Complete Resolution of Symptoms of Primary Orthostatic Tremor with Perampanel

Maria Ruiz-Julián, Jorge Luís Orozco, Alexandre Gironell

Abstract


Background: Primary orthostatic tremor (POT) is an infrequent disorder whose physiopathology is unknown. Current medication is largely ineffective or only offers mild benefits.

Case Report: A 75-year-old female with refractory POT treated with 4 mg/day of perampanel achieved complete symptom resolution. Owing to adverse effects, the patient reduced intake to 2 mg/day, but even at this lower dose the benefit was maintained.

Discussion: We report the complete resolution of POT symptoms using low doses of perampanel, an antiepileptic drug that blocks glutamate-mediated post-synaptic excitation. Further controlled studies are necessary to confirm this finding.
