Autoimmune diseases that attack the brain include Autoimmune Encephalitis, where the immune system attacks brain cells causing inflammation, and Multiple Sclerosis (MS), which targets the myelin sheath around nerve fibers in the central nervous system. Other related conditions are Autoimmune Epilepsy and specific antibody-mediated disorders like anti-NMDA receptor encephalitis, leading to psychiatric, movement, or memory issues, with early diagnosis and treatment being crucial.
Autoimmune encephalitis (en-sef-uh-LIE-tis) is a group of conditions that causes swelling in the brain. This happens because the immune system mistakenly attacks brain cells. Autoimmune encephalitis symptoms can vary but may include memory loss, changes in thinking, changes in behavior and seizures.
The early phase of the disease may include flu-like symptoms, such as headache, fever, nausea and muscle pain. Psychiatric symptoms may appear, disappear and reappear. Later symptoms may be more severe, such as a lower level of consciousness and possible coma.
Recent studies indicate that autoantibodies play an important role in the development of cardiac arrhythmias, including atrial fibrillation, modulation of autonomic influences on heart rate and rhythm, conduction system abnormalities, and ventricular arrhythmias.
Is autoimmune encephalitis lifelong? Autoimmune encephalitis generally responds well to treatment and goes away. But this can take a long time for some people.
The "worst" autoimmune diseases are subjective but often ranked by severity, impact on life expectancy, and organ damage, with top contenders including Giant Cell Myocarditis (deadly heart inflammation), Vasculitis (blood vessel inflammation like GPA), Systemic Lupus Erythematosus (multi-organ attacks), Multiple Sclerosis (nervous system damage), and Type 1 Diabetes (pancreas destruction). These conditions can severely affect quality of life, cause permanent disability, and reduce lifespan if not managed effectively, though rare ones like Giant Cell Myocarditis are acutely fatal.
"An individual with autoimmune encephalitis might have 40 to 50 more years to live.
Symptoms of myositis
The main symptom of myositis is muscle weakness, which can start very gradually and cause you to trip or fall over a lot. You may also find it difficult to do things like: get up from a chair. climb stairs.
Here are some specialists who treat autoimmune diseases:
Evans syndrome is an autoimmune disorder in which antibodies attack red blood cells (RBC), which deliver oxygen to body tissues, platelets (which help blood clot), and/or neutrophils (a type of white blood cell).
NMDA Receptor IgG Antibody with Reflex, CSF (Sendout) [RCNMDA] is the preferred first-line test for autoimmune encephalitis. The most common (40-60%) of these disorders is NMDA-receptor autoimmune encephalitis.
One of the most common symptoms of brain inflammation is brain fog, that feeling of slow and fuzzy thinking. Other common brain inflammation symptoms include depression, anxiety, irritability, anger, memory loss, and fatigue.
Encephalitis is brain inflammation (swelling). Causes include viral infections, infections from insect bites or an autoimmune reaction that affects your brain. It can be life-threatening or cause long-term complications.
Myasthenia gravis (MG) is a potential “stroke mimic” especially in the elderly. However, due to recent change in trends of stroke statistics, this disease should be considered a possibility even in younger patients.
Living with an autoimmune disease is linked to a near doubling in the risk of persistent mental health issues, such as depression, generalised anxiety, and bipolar disorder, with these risks higher in women than in men, finds a large population-based UK study, published in the open access journal BMJ Mental Health.
Sometimes our immune system runs amok and attacks the organ that makes us “us” — the brain. It's called autoimmune encephalitis and it can appear out of the blue. The brain inflammation can cause confusion, memory loss, even psychosis.
If the doctor suspects a autoimmune disease, they will gather more information through lab tests, including: Antinuclear antibody (ANA), which can detect certain abnormal proteins called antinuclear antibodies that the immune system makes when attacking the body's own tissues.

Neurologist With Experience in Treating Autoimmune Disorders
These specialists have specific training and knowledge that can promote early disease recognition.
What are the symptoms of polymyositis?
Asherson's syndrome is an extremely rare autoimmune disorder characterized by the development, over a period of hours, days or weeks, of rapidly progressive blood clots affecting multiple organ systems of the body.
Recent Findings
COVID-19 is associated with a viral myositis attributable to direct myocyte invasion or induction of autoimmunity. COVID-19-induced myositis may be varied in presentation, from typical dermatomyositis to rhabdomyolysis, and a paraspinal affliction with back pain.
Why are autoimmune and allergic diseases increasing? Our genes haven't changed much in the last 70 years, but our current environment is vastly different. One dominant idea in the field is called the hygiene hypothesis. People noticed that issues with our immune systems started increasing when we improved sanitation.
There are several forms of encephalitis associated with antibodies against intracellular neuronal proteins, cell surfaces or synaptic proteins, referred to as autoimmune encephalitis. Several case reports published in the literature document autoimmune encephalitis cases triggered by COVID-19 infection.
Depression is a common response to the life changes that occur following encephalitis. Low mood and symptoms of depression may reflect the difficulty of achieving personal goals or a changed ability to take part in their usual activities, including work or social groups.
