Fatal Familial Insomnia (FFI) is an ultra-rare, neurodegenerative prion disease that destroys the brain’s ability to sleep, and causing muscle spasms leading to death within an average of 12 to 18 months. It is caused by a genetic mutation that targets the thalamus, the brain region responsible for regulating sleep-wake cycles. it typically begin between the ages of 20 and 70 (most commonly around age 40 to 50). There is currently no cure for Fatal Familial Insomnia (FFI) it is extremely fatal. FFI is degenerative, which means symptoms get more severe over time some medicines help you fall asleep, like melatonin supplements, only temporarily work to treat fatal familial insomnia (FFI). Studies found that sedatives (barbiturates or benzodiazepines) are an ineffective treatment. It can only be delayed by taking B6, B12, iron, folic acid, hospital care and psychosocial therapy.

There’s no cure for fatal familial insomnia (FFI). After a diagnosis, treatment is symptomatic to make you feel more comfortable, with palliative care. The life expectancy for a person diagnosed with FFI is poor — especially after symptoms start, where the life expectancy ranges from a few months to a couple of years. The condition is progressive, which means it gets worse with time.

Families are encouraged to participate in therapy to discuss care options not only for the person diagnosed with the condition but to emotionally support themselves and prepare for the sudden loss of a loved one.

Cause

FFI is an autosomal dominant prion disease, meaning a person only needs to inherit the mutated gene from one parent to develop it. A sporadic form (SFI) occurs spontaneously without a genetic mutation.

When there’s a mutation on the PRNP gene, the amino acids that build the PrPC proteins don’t have instructions to build the proteins correctly. This mutation is similar to folding your laundry. If you’re unsure how to fold a t-shirt, you might ball up the fabric and put it in a drawer. Over time, that drawer progressively becomes difficult to close because you collect several t-shirts that aren’t folded correctly. Misfolded t-shirts are PrPC proteins that collect on your brain and become toxic to the cells in your nervous system, which creates symptoms.

Symptoms

Symptoms of fatal familial insomnia (FFI) begin between the ages of 20 and 70. The average onset of symptoms is age 40.

Symptoms of fatal familial insomnia include:

• Difficulty sleeping that gets worse over time (progressive insomnia).
• Nervous system overactivity including high blood pressure, a faster-than-normal heart rate and anxiety.
• Memory loss.
• Hallucinations or seeing or thinking that something’s there when it isn’t.
• Involuntary muscle twitching or jerking (myoclonus).

Stages

• Stage 1 (3–6 months): Progressive, treatment-resistant insomnia begins. It is frequently accompanied by bizarre dreams, panic attacks, paranoia, and phobias.
• Stage 2 (5–9 months): Hallucinations begin as sleep deprivation worsens. The autonomic nervous system malfunctions, causing rapid heart rates, high blood pressure, excessive sweating, and fever.
• Stage 3 (3 months): Complete inability to sleep. Severe physical coordination loss (ataxia) and tremors make movement difficult.
• Stage 4 (up to 6 months): Severe dementia and loss of voluntary motor function (speech, swallowing). Patients fall into a non-interactive stupor or coma before death.

Diagnosis and Tests

Transient Global Amnesia (TGA) is a sudden, temporary episode of memory loss that comes on in an otherwise healthy person. The condition most often affects people in middle or older age. With transient global amnesia, you do remember who you are, and you recognize the people you know well. During an episode, a person cannot form new memories and is disoriented in time, but they retain their personal identity. Episodes resolve completely within 24 hours with no lasting effects. Transient global amnesia isn’t serious, but it can still be frightening. Even though the condition is harmless, it’s important to seek immediate medical care if you or a loved one experience sudden memory loss to be sure there’s not a more serious underlying cause.

Prosopometamorphopsia (PMO) or “Demon Face Syndrome” is a rare neurological disorder where an individual perceives human faces as severely distorted. Facial features may appear severely stretched, droopy, discolored, or shifted in position, sometimes taking on “demonic” or frightening attributes. Features like nose, moth, eyes, and ears sharpening or warping into intimidating, unnatural shapes. PMO is primarily a neurological condition rather than a psychiatric illness, it occurs when the visual cortex, the fusiform face area (FFA), and the superior temporal sulcus fail to communicate or process visual data correctly. meaning it is caused by structural or  functional abnormalities in the brain rather than a psychiatric illness. It is commonly connected to disruptions in the brain’s specialized face-processing network, such as the fusiform face area there are only a 100 documented cases worldwide. There is no cure for Prosopometamorphopsia (PMO), but the condition is highly treatable and more than half of all documented cases make a full recovery, either spontaneously or by targeting the underlying biological cause.

Symptoms

• Feature displacement: Eyes, noses, or mouths moving closer together, further apart, or shifting positions entirely.
• Elongation and drooping: Facial features stretching vertically or sagging unnaturally.
• Texture and color shifts: Skin appearing to shimmer, move, or change in colour.
• “Demonic” expressions: Features sharpening or warping into intimidating, unnatural shapes.
• Varying targets: Some individuals experience distortions only on one side of a face (hemi-PMO), while others see it on all faces, including their own reflection.

Causes

• Ischemic Strokes or Hemorrhages: A stroke cuts off blood flow or causes bleeding in the brain. This starves face-processing cells of oxygen, causing them to malfunction.
• Traumatic Brain Injuries: Severe physical impacts to the head bruise brain tissue. This bruising tears the neural pathways, disrupting how the brain connects facial features.
• Epilepsy or Seizures: Sudden, uncontrolled bursts of electrical activity disrupts the brain’s visual network. This electrical chaos temporarily warps incoming facial data.
• Severe Migraines: A wave of altered brain activity sweeps across the visual cortex during a migraine. This wave temporarily interferes with normal face perception.
• Lesions in Specific Pathways: Physical damage to structural bridges (splenium) blocks communication between the brain’s hemispheres. This stops the brain from combining left and right visual data correctly.

 Diagnosis

Because patients report seeing “demonic” or terrifyingly warped faces, medical professionals often misdiagnose PMO as a psychiatric condition like schizophrenia. It can lead to unnecessary prescriptions for antipsychotic medications and severe emotional distress for the patient. When the underlying organic issue is properly identified by a neurologist, targeted treatments can often reduce or entirely resolve the facial distortions.

• The Photo vs. Reality Test: Patients are often asked to look at a live person’s face while simultaneously looking at a flat, digital photograph of that same person. In many PMO cases, the live face looks distorted while the photograph looks completely normal.
• Distortion Grids and Patient Drawings: Patients look at grid charts or draw what they see. If the distortions are restricted only to human faces and do not affect everyday objects, it confirms a targeted failure in the brain’s face-processing network rather than a general eye problem.
• Differentiating from Prosopagnosia: Tests ensure the patient has PMO (where faces are recognized but distorted) rather than prosopagnosia (face blindness, where faces look normal but cannot be identified).
• Magnetic Resonance Imaging (MRI): High-resolution MRIs are used to detect structural damage, such as ischemic strokes, brain hemorrhages, traumatic brain injuries, or lesions in the splenium of the corpus callosum.
• Functional MRI (fMRI): If a standard MRI is clear, an fMRI can track real-time blood flow to see if the fusiform face area (the brain’s face detector) drops in activity when a patient looks at a face.
• Electroencephalogram (EEG): A standard or 24-hour ambulatory EEG tracks brain waves to catch abnormal electrical spikes. This confirms if the PMO is being driven by silent epilepsy or seizures.
• Lumbar Puncture (Spinal Tap): Cerebrospinal fluid is analyzed to check for neuroinflammatory markers or autoimmune antibodies, ruling out swelling or brain infections.
• Blood Panels: Comprehensive bloodwork screens for metabolic imbalances, toxic exposures, or infections that could trigger severe migraine auras or temporary hallucinations.

Treatment

This condition is extremely rare, treatment requires careful neurological and psychiatric investigation. There is no standardized treatment for prosopometamorphopsia (PMO). Management depends on diagnosing and addressing the specific neurological, vascular, or structural cause behind the facial distortions. The most common strategies to manage the disorder include

• Since PMO is typically a symptom of an underlying neurological issue rather than an independent psychiatric condition, management targets the root cause.
• Neurological interventions: If MRI or EEG tests reveal a brain tumor, cyst, or lesion, surgery may be recommended.
• Vascular treatments: For cases linked to blood flow issues, medical interventions such as intravenous heparin infusions or other secondary preventatives may alleviate visual symptoms.
• Medications: Conditions triggering the distortions, such as severe migraines or epilepsy, are managed with appropriate prescriptions like anti-epileptics (e.g., valproic acid). In isolated cases, medications like rivastigmine have been used with some success.
• Cognitive Behavioral Therapy (CBT): Highly recommended for helping patients manage the severe anxiety and stress caused by the visual distortions. Therapists assist patients in recognizing their symptoms, breaking negative thought cycles, and developing cognitive coping skills.
• Neuromodulation: In rare cases of severe psychiatric distress accompanying PMO, treatments like electroconvulsive therapy (ECT) have proven effective.

Anton-Babinski syndrome also known as ABS or anton syndrome is a rare neurological condition where individuals are completely blind but firmly believe they can see. patients with ABS deny their loss of vision describing things from old memories convinced they can see again. It is Caused by brain damage in the occipital lobe. They speak, react, and attempt to navigate as if there vision is completely normal. There is no cure for Anton-Babinski syndrome (ABS), but medical treatment and specialized neurological therapies can help manage the condition.

Symptoms

• Intact Pupillary Reflexes: When a doctor shines a penlight into the patient’s eyes, the pupils contract normally. The  eyes and its optic nerves work fine, which often misleads the patient into thinking their vision is uninjured.
• Absolute Denial (Anosognosia): The patient is completely unaware of their blindness and rejects any claims that they cannot see. even though they are still blind they act, react and try to navigate as if there vision is normal.
• Plausible Defensive Excuses: When confronted with mistakes, patients create logical justifications rather than admitting blindness.
• Hazardous Independence: Because they believe they can see, they will attempt to complete complex, hazardous daily activities without assistance. They may try to walk down stairs, pour hot liquids, or step out into traffic, placing themselves in immediate physical danger.
• Active Confabulation: The brain automatically fabricates highly detailed visual descriptions of the surrounding environment to fill in the missing data. If asked to describe a doctor’s necktie, the patient will immediately supply a color or pattern without realizing they are guessing.

Cause

• Associated Brain-Injury: Because ABS is usually caused by extensive stroke or trauma, it rarely appears in isolation. Patients frequently present with accompanying neurological symptoms.
• Ischemic Stroke: Blockages in the posterior cerebral arteries (PCA) or basilar artery supplying the back of the brain.
• Cardiorespiratory Arrest: Brief periods where the brain is completely out of oxygen.
• Posterior Reversible Encephalopathy Syndrome (PRES): Severe, sudden spikes in blood pressure or complications from chemotherapy.
• Other Trauma: Brain injuries, neurotoxicity, severe central nervous system infections, or advanced multiple sclerosis. 
  National Institutes of Health.

Diagnosis and Tests

• The Menace Reflex Test: The doctor makes a sudden, threatening hand gesture toward the patient’s eyes. A sighted person will automatically blink or flinch; a patient with ABS will completely fail to blink, proving they cannot perceive the threat.
• Visual Acuity and Field Testing: The patient is asked to read a standard eye chart or count fingers held in front of them. They will score as No Light Perception (NLP), though they will confabulate and confidently guess letters or numbers that are not there.
• Tracking Movements: The doctor asks the patient to follow a moving finger or a penlight with their eyes. The patient cannot track the moving object, even though they can easily look left, right, up, or down when given explicit verbal commands.
• Intact Pupillary Reflexes: A light is shone into the eyes. The pupils contract normally in response to light. This is because the reflex pathway pathways bypass the damaged visual cortex at the back of the brain.
• Brain MRI or CT Scan: These scans are critical to confirm bilateral damage (infarcts or lesions) in the occipital lobes. An MRI will clearly pinpoint tissue damage caused by a dual-hemisphere stroke, trauma, or swelling.
• Visual Evoked Potential (VEP): In rare or highly confusing cases, a VEP test is ordered. Electrodes are placed on the patient’s scalp to measure electrical activity as light is flashed. In Anton-Babinski syndrome, the electrical signals fail to register in the occipital cortex, confirming a central processing block.
• Normal Fundoscopic Exam: The doctor uses an ophthalmoscope to inspect the retina, optic nerve, and blood vessels at the back of the eye. In this syndrome, the structures look completely healthy and clear.

Treatment

There is no cure for Anton-Babinski syndrome as of now it is focused medical treatment and specialized neurological therapies can help manage the condition especially early intervention is crucial.

• Stroke Interventions: If caused by an ischemic stroke caught within the “golden window” of a few hours, emergency treatments like systemic thrombolysis (clot-busting drugs) or mechanical clot removal can completely resolve the blockages and save the brain tissue.
• Managing Swelling and Inflammation: If ABS is triggered by extreme high blood pressure aggressive blood pressure medications can reduce brain swelling. For inflammatory conditions like multiple sclerosis, high-dose steroids or plasmapheresis (plasma exchange) can slowly reverse the symptoms.
• Long-Term Medication: Patients are typically put on blood thinners (like aspirin) and cholesterol medications (statins) to drastically reduce the risk of a secondary, potentially fatal stroke. 
•  Safe way: Completely clearing walkways of low furniture, cords, and rugs and Installing safety gates at the top of all staircases.

Alien hand syndrome (AHS) is a rare neurological disorder where a limb acts independently, performing complex, purposeful movements without conscious control. Though rare, it can sometimes also affect your legs. The condition results from damage to specific part of the brain that control movement,

This phenomenon can be a terrifying experience. You might feel like you’ve entered a horror movie and someone or something else is controlling this part of your body. Alien hand syndrome can happen with several underlying conditions or trauma, as well as after some types of brain surgery. There is no known cure available for alien hand syndrome.  A Healthcare provider may recommend physical therapy, occupational therapy or cognitive behavioral therapy to manage and improve your physical and mental health.

Symptoms

• Involuntary Grasping and Groping: The hand compulsively grabs nearby objects or gropes parts of the body.
• Inability to Release Objects: Once the alien hand clutches an object, the patient often cannot consciously force it to let go, sometimes requiring the functional hand to pry the fingers open.
• Intermanual Conflict: The affected hand actively opposes the actions of the healthy hand. For example, if the functional hand buttons a shirt or opens a drawer, the alien hand may immediately unbutton the shirt or close the drawer.
• Compulsive Task Execution: The hand may independently perform complex, habitual tasks like picking up a tool, manipulating eating utensils, or tearing the clothes the patient is wearing
• Self-Harm Behaviors (Rare): In extreme cases the hand may slap, scratch, or even attempt to choke the patient.   

Causes

The symptoms of alien hand syndrome vary but could include the following

• Corpus callosum: The middle of your brain between the right and left hemispheres.
• Parietal region: The top, back part of your brain, under the crown of your skull.
• Frontal region: The part of your brain behind your forehead.

Risk Factors

There isn’t a specific test to diagnose alien hand syndrome. A healthcare provider will review your symptoms and observe your movements during a physical exam. Let them know if you had brain surgery or a head injury.

Several medical conditions can cause involuntary movements. Tests can rule out conditions with similar symptoms. Your provider may order an imaging test like an MRI (magnetic resonance imaging) to look for lesions in your brain.

Management and Treatment

A healthcare provider may offer treatment options to manage any underlying conditions or reduce symptoms of alien hand syndrome, like:

• Medications. A provider may treat involuntary movements with antiseizure medications or neuromuscular blocking agents. Other medications may be an option depending on what symptoms you experience.
• Botulinum toxin injections. Botulinum toxin can temporarily prevent muscle movement in an area of your body. This can help with involuntary movements, but repeat treatment is necessary after several months.
• Mirror box therapy. A mirror can create an illusion to convince your brain to believe that one of your limbs moved voluntarily and is within your control.
• Distractions. If your affected hand grasps objects often, you can place a ball or soft object within reach to distract it. You can also place this hand in a pocket to prevent any unanticipated actions.
• Therapies. A provider may recommend physical therapy, occupational therapy or cognitive behavioral therapy to improve your physical and mental health.

Niemann-Pick disease type C (NPC) is a slowly progressive lysosomal disorder whose principal manifestations are age dependent. The manifestations in the perinatal period and infancy are predominantly visceral, with hepatosplenomegaly, jaundice, and (in some instances) pulmonary infiltrates. Symptoms are progressive and vary by age, but typically include visceral issues like liver and spleen enlargement in early life, followed by neurological and psychiatric symptoms such as difficulty with coordination, speaking, swallowing, learning, and seizures. Treatment focuses on supportive care and managing symptoms, as there is no cure.

Duchenne muscular dystrophy (DMD) is a  rear genetic disorder characterized by progressive muscle degeneration and weakness due to the alterations of a protein called dystrophin that helps keep muscle cells intact. It predominantly affects males, Muscle weakness becomes increasingly noticeable between the ages of 3 and 5, and most patients use a wheelchair by the time they are 12. During adolescence, heart and breathing muscles weaken, leading to serious, life-threatening complications. Duchenne is caused by a change or mutation in the gene that encodes instructions for creating dystrophin, an essential protein for muscle strength. Dystrophin is a protein that plays a key structural role in muscle fiber function. In healthy muscle, dystrophin interacts with other proteins at the cell membrane to stabilize and protect the cell during regular activity involving muscle contraction and relaxation. Genetic testing can confirm the diagnosis and identify the disease-causing mutation in the dystrophin gene.

Individuals with Duchenne produce little or no dystrophin in their muscle.

Without dystrophin, normal activity causes excessive damage to muscle cells, and over time is replaced with fat and fibrotic tissue. DMD carriers are females who have a normal dystrophin gene on one X chromosome and an abnormal dystrophin gene on the other X chromosome. Most carriers of DMD do not themselves have signs and symptoms of the disease, but a minority do. Symptoms can range from mild skeletal muscle weakness or cardiac involvement to severe weakness or cardiac effects and can begin in childhood or adulthood. boys with DMD usually did not survive much beyond their teen years. Thanks to advances in cardiac and respiratory care, life expectancy is increasing and many young adults with DMD attend college, have careers, get married, and have children. Survival into the early 30s is becoming more common than before.DMD treatment requires multidisciplinary care to coordinate the multiple specialized assessments and interventions needed to maximize function and quality of life for patients. The use of available treatments can help to maintain comfort and function and prolong life. physicians can help create individualized care plans regarding all medical and assistive aspects DMD patients require.

Signs and Symptoms

DMD causes muscle weakness that worsens over time, so common symptoms include:

• Progressive muscle weakness and atrophy (loss of muscle bulk) that begins in your child’s legs and pelvis. It occurs less severely in their arms, neck and other areas of their body.
• Calf muscle hypertrophy (increase in muscle size).
• Difficulty climbing up stairs.
• Difficulty walking that gets worse over time.
• Frequent falls.
• Waddling gait (walk).
• Toe walking.
• Fatigue.

Other common symptoms of DMD include:

• Cardiomyopathy.
• Breathing difficulties and shortness of breath.
• Cognitive impairment and learning differences.
• Delayed speech and language development.
• Developmental delay.
• Scoliosis (spine curvature).
• Short stature (height).

Cause

Duchenne muscular dystrophy (DMD) is caused by a change (mutation) in the gene that gives instructions for a protein called dystrophin. Dystrophin is a critical part of the dystrophin-glycoprotein complex (DGC), which plays an important role as a structural unit of muscle.

In DMD, both dystrophin and DGC proteins are missing, which ultimately leads to the death (necrosis) of muscle cells. People with DMD have less than 5% of the normal quantity of dystrophin needed for healthy muscles.

As people with DMD age, their muscles can’t replace the dead cells with new ones, and connective and adipose (fat) tissue gradually replaces muscle fibers.

Duchenne muscular dystrophy has X-linked recessive inheritance, but about 30% of cases happen spontaneously without a family history of the condition.

X-linked means the gene responsible for DMD is located on the X chromosome, one of two sex chromosomes. Males have an X and Y chromosome, and females have two X chromosomes.

Genes, like chromosomes, usually come in pairs. Recessive means that when there are two copies of the responsible gene, both copies must have a disease-causing change (pathogenic variant or mutation) for a person to have the condition. Since males only have one X chromosome, if that chromosome has the genetic variant that causes DMD, they’ll have DMD

Diagnosis

If your child is experiencing symptoms of Duchenne muscular dystrophy (DMD), your child’s healthcare provider will likely perform a physical exam, neurological exam and muscle exam. They’ll ask detailed questions about your child’s symptoms and medical history.

If your child’s provider suspects that your child may have DMD, they’ll likely order the following tests:

• Creatine kinase blood test: Your muscles release creatine kinase when they’re damaged, so elevated levels may indicate DMD. Levels typically peak by age 2 and can be more than 10 to 20 times above the normal range.
• Genetic blood test: A genetic blood test that looks for a complete or near-complete absence of the dystrophin gene can confirm the diagnosis of DMD.
• Muscle biopsy: Your child’s provider may take a small sample of their muscle tissue from a muscle in their thigh or calf. A specialist will then look at the sample under a microscope to look for signs of DMD.
• Electrocardiogram (EKG): As DMD almost always affects your heart, your child’s provider will likely perform an EKG to look for characteristic signs of DMD and to check the health of your child’s heart.

Management and Treatment

There’s no cure for Duchene muscular dystrophy (DMD), so the main goal of treatment is to manage symptoms and improve quality of life.

Supportive therapies for DMD include:

• Corticosteroids: Corticosteroids, such as prednisolone and deflazacort, are beneficial for delaying muscle strength loss, improving lung function, delaying scoliosis, slowing the progression of cardiomyopathy (heart weakness) and prolonging survival.
• Medication to treat cardiomyopathy: Early treatment with ACE inhibitors and/or beta-blockers may slow the progression of cardiomyopathy and prevent the onset of heart failure.
• Physical therapy: The main goal of physical therapy for DMD is to prevent contractures (permanent tightening of your muscles, tendons and skin). This usually involves certain stretching exercises.
• Surgery to help treat scoliosis and contractures: Surgery to release contractures may be necessary for severe cases. Surgery to correct scoliosis may improve lung and breathing function.
• Exercise: Your child’s healthcare provider will likely recommend gentle exercise to avoid muscle atrophy due to a lack of use. This is usually a combination of swimming pool and recreation-based exercises.

Other supportive therapies for DMD include:

• Mobility aids, such as braces, canes and wheelchairs.
• Tracheostomy and assisted ventilation for respiratory failure.

With improvement in supportive care over the years, the life expectancy of DMD has significantly improved over the past few decades. so, If you’re concerned about the risk of passing on DMD or other genetic conditions before trying to have a biological child, talk to your healthcare provider about genetic counseling. In some situations, prenatal testing may be able to diagnose DMD in early pregnancy.

Schizophrenia is a mental disorder characterized by disruptions in thought processes, perceptions, emotional responsiveness, and social interactions. Although the course of schizophrenia varies among individuals, schizophrenia is typically persistent and can be both severe and disabling. The term “paranoid schizophrenia” is an outdated name for a subtype of schizophrenia. Experts no longer use or recognize this term. Instead, experts recognize schizophrenia as a specific disease, which is part of a spectrum of related conditions that involve psychosis. Schizophrenia usually happens at different ages depending on biological sex, but it doesn’t happen at different rates. It usually starts between ages 15 and 25 for males and between 25 and 35 for females. Schizophrenia in children is rare but possible, and these cases are usually much more severe. Experts estimate about 85 people out of every 10,000 will develop this condition at some point in their lifetime. Getting the proper treatment early is the best way to improve your chances of managing the illness. Some people can recover from schizophrenia entirely and never have it return. You may need to stay on medication for a long time, possibly even for life. People with schizophrenia also have a higher risk of dying by suicide, which means treatment can be life-saving, not just helpful.

Symptoms

The key symptoms of schizophrenia are:

• Delusions.
• Hallucinations.
• Disorganized or incoherent speech.
• Disorganized or unusual behavior.
• Negative symptoms.

Delusions and hallucinations are the two symptoms that can involve paranoia.

• Delusions. These are persistent false beliefs. A person who has a delusional belief usually won’t change their mind even if faced with strong evidence. Delusions involving paranoia are often “persecutory,” which means a person believes that someone is trying to harm them or negatively affect their life.
• Hallucinations. These are events a person imagines (usually in the form of something that a person hears or sees). A person who has a hallucination typically can’t tell that what they’re experiencing isn’t real. These commonly feed into delusions by giving the person additional “evidence” to confirm that someone is trying to harm or upset them.

Causes

The three main reasons that schizophrenia happens include:

• Chemical imbalances in your brain. The chemicals involved are those that your brain uses to communicate between brain cells.
• Congenital brain problems. These are problems that affect your brain’s development before you’re born.
• Communication disruptions between areas of the brain. Your brain relies on intricate networks of connections between its various areas. Experts suspect that schizophrenia happens because those connections deteriorate.

Experts believe several risk factors contribute to developing schizophrenia. Those risk factors include genetic mutations you inherit from one or both parents, exposure to certain chemicals or substances, complications during pregnancy and recreational drug use. However, experts have yet to uncover any confirmed triggers or causes for this condition.

Diagnosis and Tests

Usually a mental health specialist like a psychiatrist, diagnoses schizophrenia using a combination of tools and techniques. Some of the techniques involve analyzing your medical and personal history, asking you questions about your experiences and symptoms, and observing your behavior and actions.

Combining those methods is necessary because diagnosing schizophrenia requires the following:

• At least two of the five main symptoms.
• Main symptoms that have lasted at least one month, and overall effects that have lasted at least six months.
• Disruption in your social or work life.

The possible tests include:

• Imaging tests. These can include computerized tomography (CT) scans, magnetic resonance imaging (MRI) scans and other imaging tests.
• Blood, urine and cerebrospinal fluid (spinal tap) tests. These tests look for chemical changes in bodily fluids, as well as heavy metal poisoning, infections and more.
• Brain activity testing. An electroencephalogram (EEG) analyzes and records the electrical activity in your brain, which can rule out seizures or epilepsy.

Management and Treatment

Schizophrenia is almost always treatable, but it isn’t curable. Some people can recover from schizophrenia entirely and never have it return. However, experts consider people in that situation “in remission” because there’s no way to predict if it will or won’t return. Schizophrenia treatment will center on managing your symptoms. You may need to stay on medication for a long time, possibly even for life. Psychotherapy, a kind of talk therapy, will likely also be a big part of the plan to help you understand and manage your symptoms.

Epilepsy is the fourth most common neurological disorder in the world. If you have epilepsy, surges of electrical activity in your brain can cause recurring seizures. coming to Sleep-related hypermotor epilepsy (SHE), formerly known as nocturnal frontal lobe epilepsy, is a form of focal epilepsy characterized by seizures which arise during sleep. The seizures are most typically characterized by complex motor behaviors. This disorder is associated with cognitive impairment in at least half of patients as well as excessive daytime sleepiness due to poor sleep quality. This disorder is sometimes misdiagnosed as a non-epileptic sleep disorder. There are many potential causes of SHE including genetic, acquired injuries and structural abnormalities. In 1981, Lugaresi and Cirignotta described a group of 5 patients with paroxysmal attacks of violent movements of the extremities and dystonic-tonic posturing. It was initially uncertain whether these events constituted seizures or something else. However, the patients had a good clinical response to the anti-seizure medication carbamazepine. Ultimately, the epileptic nature of this condition was confirmed with EEG and suggested that they were coming from the frontal lobe. The term “nocturnal frontal lobe epilepsy” was suggested as a name for this condition. Later in 2014, a consensus conference recommended that the name be changed to sleep-related hypermotor epilepsy. There were three main justifications for this change: (1) not all seizures arise from the frontal lobe; (2) seizures do not necessarily occur during the night but rather from sleep; (3) hypermotor describes the most common visible clinical manifestation of the seizures. Although there is no known cure for epilepsy, developments in treatment have made it possible for most people to achieve seizure control. The first treatment step is usually to find the right medicine or Anti-Epileptic Drug (AED). If seizures continue to happen, other treatments like devices, dietary therapies, or surgery can help control seizures.

Symptoms

Seizures in SHE are brief and usually have an abrupt onset and offset.The observable clinical manifestations may consist of rapid, hyperkinetic movements as well as tonic/dystonic posturing of the limbs.Other potential manifestations include brief arousals from sleep or wandering ambulatory behavior. Non-motor manifestations (such as sensory or emotional phenomenon) are common and retained awareness during seizures may occur. Seizures usually occur during non-REM sleep. The frequency of seizures can be very high and as many as dozens may occur every night which results in poor sleep quality. In addition, many patients with SHE suffer from cognitive impairment and have behavioral/psychological problems. There are many risks associated with nocturnal seizures including concussion, suffocation and sudden unexpected death (SUDEP).

Causes

Approximately 86% of SHE cases are sporadic, 14% of patients have a family history of epilepsy and 5% are inherited in an autosomal dominant manner (i.e. autosomal dominant sleep-related hypermotor epilepsy). Both genetic, structural and multifactorial etiologies can occur. In structural cases, the most common pathology is focal cortical dysplasia.^[10]

The first described mutation in SHE was found in genes coding for the neuronal nicotinic acetylcholine receptor.Since then multiple other genes have been identified including KCNT1, DEPDC5, NPRL2, NPRL3, PRIMA1, CABP4, CRH and others. In some cases, structural and genetic etiologies can coexist such as with mutations in DEPDC5.

Diagnosis

Myasthenia gravis is a disease-causing fluctuating weakness of muscles like that of the limbs, swallowing and eye movement muscles. Myasthenia gravis (autoimmune type) happens when your body’s immune system mistakenly attacks itself. Myasthenia gravis affects how your nerves communicate with your muscles. It leads to muscle weakness that worsens throughout the day and with activity. Drooping eyelids and/or double vision are often the first sign Researchers aren’t sure why this happens. Studies suggest that certain immune system cells in your thymus gland have trouble identifying what’s a threat to your body (like bacteria or viruses) versus healthy components. A genetic changes causes congenital myasthenia. Antibodies passed from a birthing parent to a fetus during pregnancy cause neonatal myasthenia. Medications and surgery can help relieve the symptoms of this lifelong illness. Treatment includes medications  that can reduce your symptoms. Monoclonal antibodies: Doctor will give intravenous (IV) or subcutaneous (SQ) infusions of biologically engineered proteins. These proteins suppress an overactive immune system, Plasma exchange (plasmapheresis): An IV connected to a machine removes harmful antibodies from your blood plasma and replaces them with donor plasma or a plasma solution.  Last option is  thymectomy surgery is done to remove the thymus gland.

Causes

Myasthenia gravis (autoimmune type) happens when your body’s immune system mistakenly attacks itself. Researchers aren’t sure why this happens. Studies suggest that certain immune system cells in your thymus gland have trouble identifying what’s a threat to your body (like bacteria or viruses) versus healthy components.

A genetic change causes congenital myasthenia. Antibodies passed from a birth mother to a fetus during pregnancy cause neonatal myasthenia.

Symptoms

Symptoms of myasthenia gravis may include:

• Muscle weakness in your arms, hands, fingers, legs and neck.
• Fatigue.
• Droopy eyelids (ptosis).
• Blurry or double vision.
• Limited facial expressions.
• Difficulty speaking, swallowing or chewing.
• Trouble walking.

Initial symptoms of myasthenia gravis happen suddenly. Your muscles usually get weaker when you’re active. Muscle strength returns when you rest. The intensity of muscle weakness often changes from day to day. Most people feel strongest at the start of the day and weakest at the end of the day.

In rare instances, myasthenia gravis affects muscles in your respiratory system. You may have shortness of breath or more serious breathing problems. Contact 911 or your local emergency services number if you have trouble breathing. In general, this doesn’t occur suddenly.

Types of myasthenia gravis

The types of myasthenia gravis include:

• Autoimmune myasthenia: It’s an autoimmune condition where the cause isn’t well understood but the likely cause is the production of certain types of antibodies (immune system proteins). This is the most common type.
• Neonatal myasthenia: A fetus gets certain antibodies from their birth mother who has myasthenia gravis. An infant may have a weak cry or sucking reflex at birth. These temporary symptoms usually go away after three months.
• Congenital myasthenia: It isn’t an autoimmune condition, and a genetic change causes this type.

There are two subtypes of autoimmune myasthenia:

• Ocular: The muscles that move your eyes and eyelids weaken. Your eyelids may droop, or you may not be able to keep your eyes open. Some people have double vision. Eye weakness is often the first sign of myasthenia. Ocular myasthenia gravis may evolve into the generalized form for nearly half of all people diagnosed with this type.
• Generalized: Muscle weakness affects your eye muscles and others in your face, neck, arms, legs and throat. You may find it difficult to speak or swallow, lift your arms over your head, stand up from a seated position, walk long distances and climb stairs.

Risk factors for myasthenia gravis include:

Myasthenia gravis is most common among females around age 40 and males after age 60. The condition can affect anyone at any age.

You may be more at risk of developing myasthenia gravis if you:

• Have a history of other autoimmune conditions, such as rheumatoid arthritis and lupus.
• Have thyroid disease.

If you have myasthenia gravis, your symptoms could trigger (start) if you:

• Take medications for malaria and heart arrhythmias.
• Underwent surgery.
• Had an infection.

Diagnosis and Tests

Testing confirms a diagnosis. It may include:

• Blood antibody tests: About 85% of people with myasthenia gravis have unusually high levels of acetylcholine receptor antibodies in their blood. Approximately 6% of people diagnosed have muscle-specific kinase (MuSK) antibodies.
• Imaging scans: An MRI or CT scan can check for thymus gland problems like tumors.
• Electromyography (EMG): An EMG measures the electrical activity of muscles and nerves. This test detects communication problems between nerves and muscles.

Myasthenia gravis stages

There are five main classifications of myasthenia gravis that your healthcare provider may use during a diagnosis:

• Class I: Muscle weakness only affects your eyes (ocular muscle).
• Class II: Muscle weakness is mild.
• Class III: Muscle weakness is moderate.
• Class IV: Muscle weakness is severe.
• Class V: Severe muscle weakness affects how you breathe. You may need intubation or mechanical ventilation.

Management and Treatment

There’s no cure for myasthenia gravis. But effective treatment is available to help manage your symptoms. Treatments may include:

• Medications: Certain medications can reduce your symptoms.
• Monoclonal antibodies: You’ll receive intravenous (IV) or subcutaneous (SQ) infusions of biologically engineered proteins. These proteins suppress an overactive immune system.
• Plasma exchange (plasmapheresis): An IV connected to a machine removes harmful antibodies from your blood plasma and replaces them with donor plasma or a plasma solution.
• IV or SQ immunoglobulin (IVIG or SCIG): You’ll receive IV infusions of donor antibodies over two to five days. IVIG or SCIG can treat myasthenia crisis, as well as generalized myasthenia gravis.
• Surgery: A thymectomy is surgery to remove the thymus gland.
