parkinson's study group

The medication (levodopa) for treating PD was discovered only in the 1960's. Before the 1960's, one study showed that untreated patients lived for an average of 10 years after diagnosis. As the physical disability in PD worsened with time, eventually patients became bed-ridden and succumbed to lung infection. This contributed to the shorter life span of Parkinson patients compared with those without PD
