RIGHT HAND OR LEFT HAND PARKINSON'S DISEASE

Parkinsonism Related Disorders [2008] 14 (8) : 633-635 (Yust-Katz S, Tesler D, Treves TA, Melamed E, Djaldetti R.) Complete abstract

Parkinson's Disease symptoms can initiate, develop or exist on one side, or more on one side rather than the other. The prevalence and what predicts one sided symptoms rather than the other in Parkinson's Disease have hardly been investigated. The aim of this study was to determine the rate of one sided symptoms in people with Parkinson's Disease. The dominant hand (right or left) was recorded in each person, as well as any significant right-left differences in tremor, bradykinesia, and rigidity. Symptoms dominating on one side occurred in the vast majority (85%) of people with Parkinson's Disease. The initial symptoms appeared on the right side in 47% of the right-handed patients, and on the left side in 38% of the right-handed patients. The initial symptoms appeared on the left side in 52% of the left-handed patients, and on the right side in 36% of the right-handed patients. In conclusion, Parkinson's Disease appears to be characterised by symptoms being greater on either the right or left side. There was a trend toward symptoms onset on the dominant side.
