Motor Unit Number Estimation in Idiopathic Parkinson's Disease

Abstract

Objective: Motor neuron degeneration in parkinsonism is known to develop in Western Pacific (Guam) parkinsonism-amyotrophic lateral sclerosis complex, multisystem atrophy (MSA), postensefalitic parkinsonism, Creutzfeld-Jacob disease and dementia with parkinsonism linked to chromosome 17. Existence of motor neuron degeneration in these disorders brings up the question whether motor neuron degeneration develops in Idiopathic Parkinson Disease (IPD). Our study aims to answer this question.
