NCT00988117

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Resting State Functional Activity Change From Baseline to 12 Weeks

    Fractional amplitude of low frequency fluctuations (fALFF) was used to measure brain activity. This metric is derived from task-free functional magnetic resonance imaging (fMRI) and represents the power of regional spontaneous and intrinsic brain activity at the local, voxel-wise level while the subject is at rest. More specifically, the amplitude of low-frequency fluctuations (ALFF) is the total power in the low-frequency range, and fALFF is calculated by dividing ALFF by the total power across all measurable frequencies. Whereas ALFF values increase near blood vessels and cerebrospinal fluid (CSF), likely due to pulsations in those areas, fALFF is less susceptible to artifactual signals. We measured change in these ratio scores post-treatment minus baseline and present in z-score units.

    Baseline and 12 weeks

  • Pre-post Change in Continuous Performance Test of Attention (Median Reaction Time)

    On the Continuous Performance Test (CPT), subjects press the spacebar quickly when they see a target image (a white star; 150 trials), and withhold response when they see a non-target image (5 randomly sampled white shapes; 150 trials). The inter-stimulus interval is randomly sampled from 1.5s, 2.5s, or 4s. Performance is measured by the median reaction time (milliseconds) on accurate target trials.

Secondary Outcomes (1)

  • Pre-post Change in Montreal Cognitive Assessment

    Baseline and 12 weeks

Study Arms (1)

Rivastigmine Patch 9.5 cm2

EXPERIMENTAL
Drug: Rivastigmine Patch 9.5 cm2

Interventions

Subjects will be started on a 5cm2/24hr rivastigmine patch. After 4 weeks, the dose will be increased to a recommended target dose of 9.5cm2/24hr patch for 8 additional weeks.

Eligibility Criteria

Age55 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Must meet research criteria for Parkinson's Disease with Dementia (PDD)
  • Males and females, ages between 55 and 100
  • Able to undergo psychometric testing
  • Mini-Mental State Examination ≥ 21 and Clinical Dementia Rating \< 2
  • Reliable informant with frequent contact with patient

You may not qualify if:

  • Non-English speaking, as cognitive tests will be in English
  • Evidence of other neurological or psychiatric disorders which preclude diagnosis of PDD (including, but not limited to, stroke, any psychotic disorder, severe bipolar or unipolar depression, seizure disorder, or head injury with loss of consciousness) within the past year
  • 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
  • Systolic blood pressure over 180 or less than 90 mm Hg. Diastolic blood pressure not greater than 105 or less than 50 mm Hg
  • ECG is abnormal and judged to be clinically significant by the investigator
  • Use of investigational drugs or participation in investigational drug studies within 30 days of screening
  • Geriatric Depression Score score \> 15/30
  • Hachinski score \> 4
