Assessing Cognition: Interactive Voice Response System

[This study is no longer recruiting subjects.]

The purpose of this Phase II study is to test a new Interactive Voice Response (IVR) system that has been developed for screening, education, and referral of persons with dementia. Since many of the FDA approved pharmaceutical compounds for treating symptoms of AD are effective primarily at slowing the progression of the disease, it is important to identify signs of AD in the earliest stages so individuals can benefit from the pharmaceutical treatments that are effective primarily in the early stages of the disease. That is one the goals of the Interactive Voice Response system (IVR). In Phase I, public response to IVR technology was assessed and also, screening instruments were developed and validated. In Phase II, the project will focus on modifying the IVR-based assessments developed during Phase I. The goal is to learn if this new IVR system is an effective way to evaluate longitudinal assessments using real-time scoring, and web-based reporting of individual performance records. This grant is a small business grant from the National Institute on Aging with Health Care Technology Systems (HTS). /research participants.

We plan to enroll 105 elderly subjects (65 years and over) with CDR scores of 0, 0.5, and 1. It is expected that subject recruitment will take approximately 12 months with an additional 6 months for final follow-up. Participants are interviewed at the clinic four times, approximately 8 weeks apart, and asked to take a number of psychological tests and questionnaires. In between clinic visits, they are asked to telephone the IVR system and answer a similar series of questions over the phone. Clinic responses are compared to the IVR responses to determine if the IVR is an accurate way to gather information.
