Overview
Hashimoto's Encephalopathy is a very rare condition associated with Hashimoto's Thyroiditis. Hashimoto's Encephalopathy is a neuroendocrine disorder. Much like the antibodies in Hashimoto's Thyroiditis attack the thyroid, in Hashimoto's Encephalopathy, antibodies attack neurons in the brain.
Pathophysiology
A few theories are proposed for Hashimoto encephalopathy.
- Neuronal injury due to antibody mediated destruction.
- Immmune complex mediated vasculitis
- Toxic effect of increased thyroid stimulating hormone.
