Summary: Researchers report on a novel four-year, randomized clinical trial evaluating different home-based methods to assess cognitive function and decline in participants over the age of 75.

Clinical trials to develop new therapeutic and preventive treatments for Alzheimer’s disease (AD) are costly, complicated and often preclude persons most at risk of developing the degenerative neurological condition: Older individuals with less mobility and significant medical issues, both making it more difficult for them to participate in traditional, clinic-based assessments with trained personnel.

In a new paper, published this month in the journal Alzheimer’s & Dementia, a multi-institution team led by researchers at Alzheimer’s Disease Cooperative Study (ADCS) at University of California San Diego School of Medicine published results of a novel four-year, randomized clinical trial evaluating different home-based methods to assess cognitive function and decline in participants over the age of 75.

Almost 600 persons participated in the home-based assessment (HBA) study; all had been previously diagnosed as either possessing normal cognitive abilities or suffering from Mild Cognitive Impairment, a condition that often precedes AD.

The HBA study evaluated three different methods for monitoring and measuring cognitive function, particularly as participants progressed from normal abilities to impairment and dementia. There were three primary objectives: 1. Establish feasibility and efficiency of the three home-based assessment methods; 2. Determine how home-based assessments captured cognitive change over time; and 3. Evaluate participants’ adherence in taking prescribed medication as a performance-based assessment of functional ability. (Results related to the third objective were not part of this paper.)

“We wanted to know if we could remotely assess cognition and other outcomes using various types of technology,” said first author Mary Sano, PhD, professor of psychiatry and director of the Alzheimer’s Disease Research Center at the Icahn School of Medicine at Mount Sinai in New York City. “We needed to know this because prevention of dementia studies are long and assessing people in their home may reduce the burden of traveling to medical centers for study participants.” Read the full article
