Imagine waking up one day to find that your mind is no longer your own.
Your thoughts are jumbled, memories fade, and your behavior changes dramatically.
This frightening scenario is a reality for those suffering from a condition known as “Brain on Fire” disease.
In this blog post, we’ll explore this condition, formally called autoimmune encephalitis, and shed light on its causes, symptoms, diagnosis, and treatment options.
What is Brain on Fire?
Autoimmune encephalitis is a condition where the body’s immune system mistakenly attacks healthy brain cells, causing inflammation.
This inflammation can lead to a variety of neurological and psychiatric symptoms.
The term “Brain on Fire” vividly describes the intense and often chaotic impact this disease has on brain function.
Key points
- Nature: Autoimmune condition where the immune system attacks brain cells.
- Symptoms: Can range from memory loss and confusion to seizures and hallucinations.
- Prevalence: Rare but increasingly recognized due to advancements in diagnostic techniques.

Causes and Symptoms of Brain on Fire Disease
Autoimmune encephalitis is a condition where the immune system mistakenly attacks healthy cells in the brain, leading to inflammation.
While the exact cause isn’t fully understood, it’s thought to involve a mix of genetic predisposition and environmental triggers.
Causes
- Infections: Viral or bacterial infections can sometimes trigger an autoimmune response where the immune system mistakenly targets the brain.
- Tumors: In some cases, especially with ovarian teratomas (a type of tumor), the presence of tumors can lead to autoimmune encephalitis.
- Genetics: Certain genetic factors may increase a person’s susceptibility to developing autoimmune diseases, including autoimmune encephalitis.
Symptoms
Autoimmune encephalitis can cause a wide range of symptoms that affect both the mind and body:
- Psychiatric symptoms: These can include hallucinations, paranoia, mood swings, and aggression (hostile or violent behavior).
- Neurological symptoms: These may include seizures, memory loss, confusion, and difficulty speaking (problems with communication).
- Physical symptoms: Some people may experience motor problems, such as difficulty walking or issues with coordination.
According to research published in The Lancet Neurology, psychiatric symptoms are often the most common initial signs, followed by memory problems and seizures.
This highlights the diverse ways autoimmune encephalitis can affect individuals.

How to Diagnose a Brain on Fire?
Diagnosing autoimmune encephalitis can be challenging due to its varied symptoms and resemblance to psychiatric disorders.
Early and accurate diagnosis is crucial for effective treatment and improved outcomes.
Clinical evaluation
Doctors begin by thoroughly reviewing the patient’s medical history and conducting a detailed examination of their symptoms.
They focus on changes in behavior, thinking abilities, and overall neurological function.
This careful assessment provides crucial insights into the presence and progression of autoimmune encephalitis.
MRI and CT scans
MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) scans are imaging tests that create detailed pictures of the brain.
They help doctors look for signs of inflammation or other abnormalities caused by autoimmune encephalitis.
These scans reveal structural changes in the brain affected by the immune system’s attack on healthy cells.
Electroencephalogram (EEG)
An EEG measures the brain’s electrical activity using electrodes placed on the scalp.
This painless test detects abnormal brain wave patterns, which can indicate seizures or other neurological issues associated with autoimmune encephalitis.
EEG results provide critical information about brain function, guiding diagnosis and treatment decisions.
Lumbar Puncture (Spinal Tap)
During a lumbar puncture, a small amount of cerebrospinal fluid (CSF) is extracted from the lower back.
This fluid surrounds the brain and spinal cord, and its analysis reveals signs of inflammation, infection, or specific antibodies linked to autoimmune encephalitis.
Detecting these antibodies confirms the diagnosis.
Blood tests
Blood tests play a key role in diagnosing autoimmune encephalitis by identifying specific antibodies in the blood or CSF.
These antibodies are produced by the immune system and mistakenly attack healthy brain cells, causing inflammation and neurological symptoms.
Blood tests help doctors confirm the presence of these antibodies, aiding in diagnosis and treatment planning.
According to comprehensive studies, up to 80% of patients with autoimmune encephalitis have detectable antibodies in their blood or cerebrospinal fluid.
This emphasizes the importance of blood tests and spinal taps in confirming the diagnosis of autoimmune encephalitis.

Treatment Options for Brain on Fire
Treatment for autoimmune encephalitis focuses on reducing brain inflammation and managing symptoms.
Early intervention can significantly improve prognosis and recovery.
Immunotherapy
- Steroids: These are powerful anti-inflammatory drugs that help reduce inflammation in the brain caused by autoimmune attacks.
- Plasmapheresis: This procedure involves removing harmful antibodies from the blood that are mistakenly attacking the brain.
- Intravenous Immunoglobulin (IVIG): IVIG provides healthy antibodies to help regulate the immune response and combat the disease.
Medication
- Antipsychotics: These medications help manage psychiatric symptoms such as hallucinations and mood swings.
- Anticonvulsants: These are used to control seizures, which can be a symptom of autoimmune encephalitis.
Other medications may be prescribed based on specific symptoms and their severity.
Rehabilitation
- Physical therapy: Helps patients regain strength, mobility, and coordination that may have been affected by the disease.
- Occupational therapy: Focuses on improving daily living skills and independence.
- Speech therapy: Assists with communication difficulties that may arise due to neurological symptoms.
Surgery
In rare cases where autoimmune encephalitis is associated with a tumor, surgical removal of the tumor may be necessary.
This helps eliminate the source of abnormal immune response and reduce inflammation in the brain.
According to a study published in the Neurology journal, approximately 75% of patients treated with immunotherapy showed significant improvement in symptoms.
This underscores the effectiveness of early and targeted treatment in managing autoimmune encephalitis.

Impact on Individuals and Families
The sudden onset and severe symptoms of autoimmune encephalitis can be devastating for individuals and their families.
The emotional, physical, and financial burdens are significant, and the road to recovery can be long and challenging.
Individual Impact
Mental health
Individuals may experience persistent psychiatric symptoms such as hallucinations, paranoia, mood swings, and cognitive impairments like memory loss and difficulty concentrating.
These symptoms can significantly impact their ability to function independently and lead to ongoing challenges in daily life.
Physical health
Autoimmune encephalitis can cause long-term neurological issues, including seizures, movement disorders, and problems with coordination.
These physical challenges may require ongoing medical management and rehabilitation to help improve mobility and overall physical function.
Quality of life
Many individuals find it difficult to return to normal daily activities, work, and social interactions due to the lingering effects of autoimmune encephalitis.
Adjusting to a new normal can be frustrating and may require adapting to permanent changes in health and abilities.
Family Impact
Emotional stress
Family members often experience significant emotional stress when they witness a loved one suffering from autoimmune encephalitis.
They may feel helpless, anxious, and overwhelmed as they manage the uncertainties of the disease and its impact on their loved one’s well-being.
Financial strain
The costs associated with medical treatments, hospitalizations, medications, and rehabilitation services can impose a heavy financial burden on families.
Moreover, if the affected individual is unable to work or requires ongoing care, there may be a loss of income that further compounds financial challenges.
Caregiving challenges
Providing long-term care for someone with autoimmune encephalitis can be demanding and exhausting.
Family caregivers may face challenges in balancing caregiving responsibilities with other obligations, and they may require support from healthcare professionals and community services to ensure the best possible care for their loved one.
