Palatal-Myoclonus as a Presentation of Hashimoto Encephalopathy: an interesting case report.

OBJECTIVE

Hashimoto encephalopathy (HE) is known as a steroid- responsive encephalopathy associated with autoimmune thyroiditis or nonvascular inflammation-related autoimmune meningoencephalitis. The average age of onset of HE is approximately 50 years; and it is more common in women. The onset of HE may be acute or subacute. The course of most HE cases is relapsing and remitting, which is similar to that of vasculitis and stroke.

METHODS

In this article, we present a previously healthy 32 years old;veterinarian male with palatal myoclonus, as a rare presentation of this disorder, and review the neurologic aspects of hashimoto encephalitis.

RESULTS

The clinical presentation of HE is characterized by progressive cognitive decline tremor, transient aphasia, seizures, abnormal gait, sleep disorder and stroke-like episodes. Myoclonus, either generalized or multifocal, and tremor, often of the bilateral upper extremities, is the most frequently observed involuntary movements in HE.

CONCLUSION

The rapidly progressive cognitive dysfunction and encephalopathies observed.
