[Cerebral phospholipids and Parkinson's disease: cross-over double-blind study versus placebo]

Authors refer in this study their clinical experience with brain cortex phospholipids (BC-PL) in patients affected by Parkinson's disease and treated with L-DOPA plus IDD. It's plain from results elaborated through statistical examinations a positive influence more on motor timing performances (screw-test, gait-test, peg-board test) than each item of Webster rating scale. Moreover getting in connection high nervous functions with motor activity, authors suppose BC-PL have a primary and direct action on cortical cholinergic structures correlated with attention, learning and memory and consequently a secondary action on motor performances.
