title: Obsessive-compulsive-like behavioral changes in pure akinesia.
abstract: Pure akinesia is a disorder characterized by profound freezing in the absence of rigidity or tremor that is not improved by levodopa therapy. We report two cases of pure akinesia who developed obsessive-compulsive-disorder- (OCD-) like behavior during their illness. Although the pathophysiological mechanism underlying freezing is unclear, the coexistence of pure akinesia and OCD-like behavior suggests that both symptoms have a common pathological basis in these two cases, presumably damage to the pallidum.
