Fast Orthostatic Tremor in Parkinson's Disease: Case Report and Comprehensive Review of Literature.

BACKGROUND

Orthostatic tremor (OT) is a rare symmetric tremor disorder occasionally observed in association with other movement disorders.

CASE REPORT: We report the presence of a fast OT in a case of Parkinson's disease (PD), and provide a comprehensive review of the literature.

DISCUSSION: A fast OT presenting as unsteadiness may be a presenting symptom of PD. This symptom may be nonresponsive to levodopa, and benzodiazepines should be prescribed to adequately control the OT and reduce disability.
