About Hashimoto Encephalopathy
Hashimoto encephalopathy is a rare autoimmune disorder that affects brain function. It occurs in about two out of every 100,000 people. The condition is named because of its potential link to Hashimoto's thyroiditis, an autoimmune thyroid disease. However, the exact relationship between the two disorders is still not understood.
People with Hashimoto encephalopathy have anti-thyroid antibodies, which are immune cells that mistakenly target thyroid tissue. It is unclear if the presence of these antibodies contributes to the development of Hashimoto encephalopathy. This condition can cause various neurological and mental health symptoms, such as seizures, confusion, personality changes, hallucinations or delusions, depression, and cognitive impairment. Treatment for Hashimoto encephalopathy typically involves medications to reduce inflammation and manage symptoms. It is important to consult with a healthcare professional for individualized advice and guidance.
The exact disease causes of Hashimoto encephalopathy are still unknown, but it is believed to be an autoimmune disorder. It may occur due to an abnormal immune response triggered by an infection or other factors.
Non-modifiable factors of Hashimoto encephalopathy are factors that cannot be changed or controlled. These include:
- Increasing age
- Genetic predispositions, such as a positive family history of the condition or related autoimmune disorders.
On the other hand, there are no specific modifiable risk factors (those that can be influenced or changed) directly associated with Hashimoto encephalopathy. However, it's important to note that maintaining a healthy lifestyle, including regular exercise and a balanced diet, can generally support overall well-being and potentially reduce the risk of autoimmune disorders.
It is always best to consult with a healthcare professional for personalized advice and guidance regarding risk factors and prevention strategies.
Common symptoms of Hashimoto encephalopathy include:
- Headaches
- Personality changes: Acting differently than usual, such as becoming more irritable, withdrawn, or overly emotional
- Dementia: Problems with memory, thinking, or decision-making that make daily tasks harder
- Delusional behavior: Strongly believing thing that aren’t true, even when there’s evidence to the contrary
As Hashimoto encephalopathy progresses or reaches higher severity, other common symptoms that may occur include:
- Seizures
- Ataxia (loss of coordination)
- Aphasia (difficulty speaking or understanding language)
- Coma
- Hallucinations: Seeing, hearing, or feeling things that aren’t really there, such as hearing voices or seeing objects that don’t exist
It's important to note that the symptoms of Hashimoto encephalopathy can vary between individuals, and not everyone will experience the same symptoms. Additionally, it's worth mentioning that Hashimoto encephalopathy is a rare condition and its exact causes and relationship with Hashimoto's thyroiditis are still not fully understood. If you suspect you or someone you know may have Hashimoto encephalopathy, it is important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
To diagnose Hashimoto encephalopathy, doctors may perform the following examinations, tests, and procedures:
- Medical history: Doctors gather information about your symptoms, medical background, and any previous diagnoses.
- Physical evaluation: A thorough physical exam is conducted to look for physical signs of a medical problem.
- Blood tests: These tests can detect antithyroid antibodies, which may be present in Hashimoto encephalopathy. However, these antibodies are common in the general population, so doctors consider them alongside with other symptoms.
- MRI (magnetic resonance imaging) scans: This imaging test uses magnetic fields and radio waves to create a detailed 3D image of the brain. It can help rule out other causes of symptoms and may show brain changes that could support the diagnosis Hashimoto encephalopathy.
- EEG (electroencephalogram) recordings: This test measures the brain’s electrical activity in the brain and can detect problems like seizures or slowed brain waves, which are common in Hashimoto encephalopathy.
Additional examinations, tests, and procedures may be performed based on initial findings or individual factors. These may include:
- Neurologic examination: This evaluates brain and nervous system function, checks for signs of brain damage, and helps identify which areas of the brain or nervous system may be affected. damage localization, systemic symptoms like rash or lymphadenopathy, and early prognostic indicators.
- Mental status tests: These assess cognitive functions, such as memory, attention, and problem solving, as well as changes in mental state, like confusion or disorientation.
- Memory tests: These evaluate memory function.
- Coordination tests: These assess motor coordination abilities.
It's important to follow up with your healthcare provider if your symptoms worsen or change after the initial evaluation. They may recommend further clinical procedures based on your specific situation.
The goals of treatment for Hashimoto encephalopathy are to reduce inflammation in the brain, manage symptoms, and improve overall brain function. The following treatments may be recommended.
- Medications:
- Corticosteroids: Medications like prednisone and methylprednisolone are used to reduce inflammation in the brain.
- Immunosuppressants: Drugs such as cyclophosphamide, azathioprine, and mycophenolate mofetil can help reduce immune system activity and inflammation throughout the body.
- Anti-seizure drugs: These medications may be prescribed to manage seizures associated with Hashimoto encephalopathy.
- Therapies and Therapeutic Procedures:
- Intravenous immunoglobulin (IVIG) therapy: Large doses of antibodies from donor blood are given to target immune cells causing brain inflammation.
- Plasma exchange: Some of the person's blood is removed, and the missing component is replaced with healthy donor plasma. This helps reduce antithyroid antibody levels in the body.
It is important to note that individual treatment plans may vary. Health behavior changes, such as maintaining a healthy lifestyle and managing stress, can also support overall well-being. It is essential to consult with a healthcare professional for personalized advice and treatment options.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for side effect information.
