Autoimmune musicogenic epilepsy associated with anti-glutamic acid decarboxylase antibodies and Stiff-person syndrome.

Epilepsy should be suspected in patients with Stiff-person syndrome and new onset paroxysmal episodes. Musicogenic epilepsy may be a manifestation of anti-GAD-Ab spectrum, supporting an autoimmune workup in these patients. Appropriate treatment is not well established, and immunotherapy should be considered in patients with only partial response to antiepileptic drugs.
