Brief Summary
The purpose of this trial is to determine if patients who received embryonic dopamine cell implant surgery showed significantly greater improvement in their Parkinson's disease than a control group undergoing the placebo treatment, and to determine if the cell implant surgery was more effective in younger or older patients.

Interventions
Half of the participants received the cell implant surgery, while the other half received the placebo. After the double-blind phase of the study, patients in the placebo group had the option of receiving tissue implants. Fourteen of these patients eventually had transplants.
Eligibility Criteria
You may qualify if:
- Idiopathic Parkinson's disease of at least 7 years duration and responsive to levodopa. Other Parkinson syndromes excluded.
- Patients previously tried on other available forms of medical treatment.
- Age between 20 and 75 years.
- Presence of an intractable problem, such as "off" periods, dyskinesias, or "freezing," not controlled by dopamine agonists such as levodopa or pergolide.
- No serious depression and no cognitive impairment.
- Successful completion of home diary by patient or responsible party.
- Successful videotape recordings at home of "on" and "off" status.
- Normal MRI of brain within the last 18 months.
- Fluorodopa PET scan compatible with idiopathic Parkinson's disease.
- Medically fit to undergo implant surgery with certification by the patient's physician.
- Able to financially cover expenses not paid for by NIH grant (between $1,000 and $2,000 for unreimbursed travel, video camera, and blood screening as specified in the consent form.
You may not qualify if:
- Severe or moderately severe depression or cognitive impairment.
- Previous brain surgery.
- Presence of diabetes mellitus, severe cardiopulmonary disease or other severe medical disease, or MRI evidence of cerebrovascular disease.
- Not medically cleared to undergo a surgical procedure.
