The Effects of the Rivastigmine Patch on Parkinson's Disease With Memory and/or Thinking Problems

Completed · Phase 4

Conditions studied: Parkinsons Disease With Dementia, Parkinsons Disease With Mild to Moderate Memory and/or Thinking Problems

In brief

This is an open-label study to investigate the effects of the rivastigmine patch on attention and behavior in Parkinson's disease when associated with memory and/or thinking problems. Rivastigmine (also sold under the name Exelon) is an FDA approved medication used for the treatment of mild to moderate Alzheimer's Disease (AD) and memory or thinking problems due to Parkinson's disease. Recently a rivastigmine patch was developed, which has shown similar effectiveness with fewer side effects and increased caregiver preference when compared to capsules. This is an open-label 12 week study where 15 subjects diagnosed with Parkinson's Disease who have mild to moderate memory and/or thinking complaints will be treated with the rivastigmine patch at UCSF. This study also analyzes the mechanism by which the rivastigmine patch works in people with Parkinson's disease and memory and/or thinking problems.

• Concurrent treatment with any acetylcholinesterase inhibitors (including rivastigmine in pill or patch form), antipsychotic agents (excluding quetiapine in dosages of 150 mg and lower, abilify and geodon as these medications are commonly used in treatment of Parkinson's Disease (PD) psychosis and should not affect results of study), mood stabilizers (valproate or lithium) or benzodiazepines (other than temazepam or zolpidem)
• Positive urine drug screen or suspected alcohol or substance abuse within last 1 year
• Current malignancy, or any clinically significant hematological, endocrine, cardiovascular, renal, hepatic, gastrointestinal or neurological disease. If the condition has been stable for at least the past year and is judged by the investigator not to interfere with the patient's participation in the study, the patient may be included
