Brief Summary

This study will examine and compare blood samples from healthy volunteers and patients with Parkinson's disease to identify abnormalities associated with Parkinson's disease. Disease symptoms include slowness of movement, hand or leg shaking, and stiffness. Some patients have difficulty with balance. Information from this study may provide information on how Parkinson's disease affects the brain and body, and may help lead to a test for earlier diagnosis. Healthy volunteers and patients with Parkinson's disease who are 18 years of age or older may enroll in this study. Participants will undergo the following procedures:

• Physical examination, including evaluation of strength, feeling, coordination, and balance
• Blood drawing: 150 milliliters (about 10 tablespoons) of blood will be drawn
• Personal and family medical history
• Consent to access medical records for research purposes Blood samples will be examined for:
• Genetic analysis
• Study of specific proteins and lipids
• Study of mitochondria (parts of cells that make energy)

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Individuals over the age of 18 from families in which an inherited form of parkinson's disease is apparent will be enrolled. These patients are already enrolled in the Genetic linkage analysis protocol 97-HG-0173.
• The diagnosis of Parkinson's disease must be supported by accepted clinical criteria including: tremor, bradykinesia, rigidity and responsiveness to L-DOPA.
• Unaffected family members found to be at risk, will also be enrolled.
• The normal control group will be comprised of anonymous platelet donors from the NIH Department of Transfusion Medicine and of individuals over the age of 18 with no known neurological disorder and normal neurological examination matched by age and sex that may be actively recruited.
• Individuals with Lewy Body disease (LBD) that meet current criteria for diagnosis (hallucinations, diurnal variation, and dementia associated with extrapyramidal symptoms within a one year period) will also be included in the study.

You may not qualify if:

• Because some medications can alter mitochondrial function, patients on MAO inhibitors, antidiabetic sulfonylureas and benzodiazepines will be excluded from the study.
• No person under the age of 18 will be enrolled in this study. This is due to the fact that, except for very rare occasions, Parkinson's disease affects only adults.
