Key exclusion criteria
* History of any significant neurologic or psychiatric disorder other than PD that can contribute to cognitive impairment.
* Any other condition or clinically significant abnormal findings on the physical or neurological examination, medical and psychiatric history, at screening or at baseline that, in the opinion of the Investigator, would make the subject unsuitable for the study.
* Potential symptomatic causes of cognitive impairment including but not limited to
* abnormal thyroid function test at screening (TSH)
* abnormal B12 level at screening
* MRI findings (by history) pointing to a potential symptomatic cause of cognitive dysfunction, including significant vascular changes, or communicating hydrocephalus.
* Treatment with memantine or amantadine. If appropriate the drugs can be discontinued for a minimum of 4 weeks prior to enrollment.
