Evaluation of a Handheld Event-Related Potential (ERP) System as an Effective Method to Diagnose Alzheimer's Disease - Full Text View

Purpose

This study will evaluate a handheld event-related potential (ERP) testing device from Neuronetrix, Inc. as a method to screen elderly adults for Alzheimer's disease or other age-related dementias.

An ERP system records electrical signals at the scalp that are produced by the brain when performing simple tasks. By doing this study, we hope to learn whether these electrical signals can be used to differentiate normal aging from dementia.

Primary Outcome Measures:

Complete ERP tests along with automated classifier training with all subjects. [ Time Frame: 9 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To perform statistically significant classifications for the 2 cohorts. [ Time Frame: 9 months ] [ Designated as safety issue: No ]

Biospecimen Retention: None Retained

Biospecimen Description:

Estimated Enrollment:	50
Study Start Date:	January 2008
Estimated Study Completion Date:	June 2008
Estimated Primary Completion Date:	September 2008 (Final data collection date for primary outcome measure)

Groups/Cohorts

1

Mild-moderate Alzheimer's Disease

2

Age-matched Controls

Detailed Description:

Patients who have a current diagnosis of mild-moderate dementia and suspected of having Alzheimer's disease (AD) along with cognitively normal age-matched controls will be recruited for this study. The Alzheimer's subjects either will have had a complete clinical and neuropsychiatric workup or will have those tests performed during the study.

Both groups, AD and controls will be asked to listen to a series of sounds and press a button on a handheld control box when a target sound is heard. A headset on each subject's head will then record the electrical signals during this task.
