A single oral zolpidem tablet (5 mg) administered in clinic and then each day for the following 3 days
Zolpidem is a non-benzodiazepine sedative/hypnotic agent usually prescribed for insomnia.
Other Name: Stilnoct
Placebo Comparator: Placebo
A single oral placebo administered in clinic and then each day for the following 3 days
- Changes in motor function [ Time Frame: 1 day ]In the clinic (day 1), motor function will be assessed before and after active/placebo administration using the Unified Parkinson's Disease Rating Scale (Part III). This involves 26 assessments (scored 0-4) including of tremor, rigidity, agility and posture. Scores therefore range from 0 to 104, the higher the score indicating reduced motor function.
- Changes in cognitive function [ Time Frame: 1 day ]
In the clinic (day 1), cognitive function as measured by phonetic/letter fluency and semantic/category naming tasks. These test will be conducted on day 1 before and after active / placebo administration.
The letter fluency test involves the participant giving as many different words as possible beginning with a specific letter, in 60 seconds. The category naming tasks involves the participant giving as many different examples from a given specific category (i.e, animals) in 60 seconds. The higher the score the greater the cognitive ability.
- Motor performance [ Time Frame: 6 days ]Objective measures of motor performance will be conducted using a mobile phone application specifically designed for Parkinson's patients (see Arora et al., 2015. Parkinson's and Related Disorders 21; 650-653) which measures motor performance including: testing of posture; gait; tremor; and reaction times. The testing protocol is for all patients (active and placebo) to perform tests 4 times per day on each of days 2 - 7, 3 days while taking drug/placebo, then 3 days not taking drug/placebo.
