Research is focused on Parkinson's disease. There are several research arms. The first relates to the connection between sleep disorders and Parkinson's disease, specifically looking at whether sleep disorders can predict either the risk of developing Parkinson's disease, or the prognosis of Parkinson's disease. Other areas include the effect of levodopa on homocysteine levels in the blood, sources of variation in severity of Parkinson's disease, and risk factors for Parkinson's disease (especially surrounding birth).Parkinson's disease, REM sleep behavior disorder, homocysteine
