Cognitive decline key factor in predicting life expectancy in Alzheimer’s

Cognitive decline is the biggest factor in determining how long patients with Alzheimer’s Disease will live after being diagnosed, according to a new study from researchers at UT Southwestern. The findings, published in the Journal of Alzheimer’s Disease, are a first step that could help health care providers provide reliable prediction and planning assistance for patients with Alzheimer’s disease and their families.

Using a National Alzheimer’s Coordinating Center dataset on 764 autopsy-confirmed cases, C. Munro Cullum, Ph.D., Professor of Psychiatry, Neurology, and Neurological Surgery, and first author Jeffrey Schaffert, Ph.D., a postdoctoral fellow in clinical neuropsychology at UT Southwestern, identified seven factors that helped predict life expectancy variances among participants. These factors are the most predictive of how many years of life remain after diagnosis.
