Clinical Trial
Development of Cognitive Assessment Tools in Parkinson Disease
The main objectives of this protocol are as follows: 1. To assess the sensitivity and specificity of ANAM-PD in detecting cognitive status in patients with Parkinson disease (PD) and healthy controls (HC). 2. To validate the specific individual domains of the ANAM-PD cognitive battery by comparisons to available standardized cognitive evaluation scales administered to the patients with Parkinson disease with and healthy control subjects. 3. To evaluate the reliability of the ANAM-PD battery of tests by comparing repeated administrations of the ANAM-PD battery on a sub-set of subjects with Parkinson disease and healthy controls. 4. To characterize cholinergic neurotransmission through imaging the vesicular acetylcholine transporter binding with 123Iodobenzovesamicol (IBVM) and SPECT in PD patients and healthy controls.
