Hi,

Thank you for your query. I can understand your concerns.
Parkinson's Disease typically does not cause muscle weakness .
Weakness of legs and hands experienced by your father is due to severe bradykinesia due to Levodopa (sundopa 110mg-TID) induced motor complications 'wearing-off effect'.
With continued treatment,the duration of benefit following an individual dose becomes progressively shorter . During such "off" periods they suffer severe parkinsonism (akinesia & tremoring very frequently).They can often be improved by dividing the levodopa into smaller but more frequent doses, or by converting to a slow release preparation. These patients may also be benefited by giving Levodopa with Selegiline. Selegiline, a type B monoamine oxidase inhibitor, inhibits catabolism of dopamine in the brain. This sometimes smoothes out the response to levodopa.
