title: Pure akinesia due to lewy body Parkinson's disease: a case with pathology.
abstract: The case of a patient with levodopa-responsive pure akinesia and freezing of gait for 17 years, whose brain showed the classical changes of Lewy body Parkinson's disease at postmortem is presented. A short trial of DL-threo-DOPS was ineffective. Intellectual function was preserved despite the presence of Lewy bodies and mild cell loss in subcortical cholinergic nuclei. Pure akinesia is likely to be a heterogeneous condition, with most cases having little or no response to levodopa therapy. However, this case demonstrates that this clinical picture may be caused by Lewy body Parkinson's disease.
