The primary goals of the Cognitive/Psychiatric Working Group are to:
Increase awareness of cognitive/behavioral aspects of PD among clinicians, researchers, and patients.
Develop and conduct multidisciplinary, translational research studies investigating the cognitive and behavioral symptoms of Parkinson’s disease.
Assist in design and conduct of PSG clinical trials to incorporate optimal tools for measuring cognition and behavior.
Foster collaboration and provide guidance to PSG members in developing investigator initiated studies on cognition and behavior in PD.
Each working group has a mandate statement that describes the goals of the working group, potential scope of working group activity, examples of ideas for projects, and procedures for member initiated proposals. A pre-proposal request form is provided to submit preliminary proposals/ideas to working groups to provide feedback and discussions that will help the investigator to improve the plan and potentially to prepare a more complete proposal for submission to the PSG Scientific Review Committee or for a submission to other funding agencies.

The Working Group (PI: Ergun Uc) completed a data-mining study examining the clinical predictors and incidence of cognitive impairment and depression in early PD using the DATATOP cohort.

Dr. Chou coordinated a task force to make recommendations for a cognitive assessment that could be consistently administered in clinical trials of PD. The Task Force conducted a systematic literature search for cognitive assessments previously used in a PD population. Scales were evaluated for their applicability in clinical trials, including administration time, assessment of the major cognitive domains, potential to detect subtle cognitive impairment, psychometric properties, and sensitivity to progression and to treatment effects.

The Cognitive/Psychiatric Working Group sponsored the “Second Clifford W. Shults Symposium: Cognitive & Psychiatric Aspects of Parkinson’s Disease” on May 28, 2009 during the 21st Annual Meeting of the Parkinson Study Group. The organizing committee consisted of Drs. Uc (chair), Growdon, Chou, Marder and Ms. Marsha Tennis.
Dr. Karen Marder (Columbia University), along with Lorraine Clark, PhD, conducted a study on genotyping blood samples collected during the DATATOP study to determine the association between several PD related mutations with dementia incidence in PD. An abstract was presented at the AAN 2010.
