Study Summary

The purpose of this research is to evaluate the usefulness of memantine, compared to placebo (sugar pill), for the treatment of cognitive impairment in patients with idiopathic Parkinson's disease (PD) and dementia. Memantine is used as a safe and effective treatment for patients with Alzheimer's disease. Cognitive impairment includes concentration and memory difficulties. We will look at how well this medication helps your cognitive impairment, how well you tolerate this medication (including its effects on your motor symptoms of PD) your activities of daily living, your emotions, and any medical conditions you might have. We will interview a person you choose as your "informant".

Primary Outcome

The DRS is comprised of: Attention (ATT, 8 items); Initiation-Perseveration (I-P, 11 items); Construction (CONST, 6 items); Conceptualization (CONCEPT, 6 items); and Memory (MEM, 5 items). For this study, only the memory subscore was used, with score possibilities ranging from 0-5, with 5 meaning memory was perfect, 0 being no ability to recall. A negative score indicates a decrease in memory from baseline to 24 weeks.
