  Purpose

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.

Detailed Description:

General Design and Methods The overall goal of this proposal is to validate ANAM-PD as an assessment tool for cognitive status in PD. We propose a comprehensive strategy to evaluate the sensitivity and specificity of ANAM-PD in detecting cognitive changes in patients with a diagnosis of PD (n=50) and healthy controls (n=25). The specific testing domains of the ANAM-PD battery will be validated against standardized neuropsychological testing, described in detail below. The reliability of the ANAM-PD battery will be evaluated through a test-retest procedure in a subset of 50 subjects (25 PD and 25 HC). This strategy will enable us to evaluate the individual domains of the ANAM-PD computerized cognitive test and establish a battery as a standard test to efficiently measure cognitive changes in PD. We also propose to explore functional neuroimaging of the cholinergic system using [123I] IBVM and SPECT, a marker of vesicular acetylcholine transporter and a measure of the integrity of the cholinergic neuronal system. Identifying and validating ANAM-PD as an efficient tool for assessing cognitive changes in PD and exploring the cholinergic transporter system in PD through functional neuroimaging could predict sub-sets of PD patients 'at risk' for developing dementia and help elucidate the neurochemistry related to cognitive decline in PD
