Pattern of subclinical pulmonary dysfunctions in Parkinson's disease and the effect of levodopa



We performed a detailed evaluation of pulmonary function in 53 patients with idiopathic Parkinson's disease (PD) who did not have symptoms of pulmonary or cardiac dysfunction. There was a significant pulmonary dysfunction of restrictive type which partially responded to levodopa. Compared to men, women were more severely affected. Pulmonary function assessment is recommended in PD, irrespective of severity of disease. © 2007 Movement Disorder Society
