What are the symptoms of Hashimoto's encephalitis?

The symptoms of Hashimoto's encephalitis are variable among individual patients. The relapsing/remitting vasculitic type typically manifests with encephalopathy and stroke-like episodes. The diffuse progressive type has a more insidious onset and progressive course with occasional fluctuations and is characterized by psychiatric symptoms and dementia. Either type might also present with tremor, myoclonus, seizures, aphasia, stupor (a state in which the patient is unresponsive but can be aroused briefly by a strong stimulus, such as sharp pain), hypersomnolence (excessive sleepiness), gait ataxia, or coma.[1]
