This randomized, controlled trial (RCT) evaluates the benefits of expressive compared to neutral writing in individuals with Parkinson's Disease and their support persons. Participants will be randomly assigned to complete three, 20 minute sessions of expressive or neutral writing. Participants will complete evaluation of outcomes at baseline, immediate post, 4 month and 10 month follow ups to establish if benefits remain over time. Impact of these therapies on thinking abilities, physical health, and patient and support person ratings of thinking skills, mood and quality of life will be evaluated. Expressive writing is hypothesized to result in greater improvements and/or stability of function on neuropsychological tests of attention, working memory, learning, and memory skills compared to the neutral writing condition.

Results from this study will determine whether brief writing exercises are easily used by and beneficial for individuals with Parkinson's Disease and their support persons. If positive benefit is observed, information from this study will be used to further optimize these therapies for larger trials designed to evaluate the value of the therapies for individuals with Parkinson's Disease and their support persons.

The expressive writing condition asks participants to write about the most stressful or traumatic experience of their entire lives over three, 20 minute private writing sessions. The neutral control writing conditions asks participants to write about how they spent their time the day before.
