Hashimoto's encephalopathy
Hashimoto's Encephalopathy is a very rare condition associated with Hashimoto's Thyroiditis first described in 1966. It is classified as a neuroendocrine disorder.
Clinical features
Some of the most common symptoms of Hashimoto's Encephalopathy include: disorientation, psychosis, tremors, concentration and memory problems, jerks in the muscles and lack of coordination, headaches, partial paralysis on the right side, speech problems, seizures and coma.
Laboratory and radiological findings
Thyroid antibodies in the disease are increased but do not correlate with the severity.
Differential diagnosis
Sometimes, patients are mistakenly diagnosed as having had a stroke, or having Alzheimer's disease.
Treatment
Because most patients respond to steroids or immunosuppressant treatment, this condition is now also referred to as steroid-responsive encephalopathy.
Aetiology
The mechanism of pathogensis is not known but it has been assumed to be an autoimmune disorder. Consistent with this hypothesis alpha-enolase has been identified as an autoantigen in the disease.[1]
Alternative names
- Steroid-responsive encephalopathy associated with autoimmune thyroiditis, SREAT
- Sometimes also mentioned as nonvasculitic autoimmune meningoencephalitis, NAIM
