Worries about getting Alzheimer's: who's concerned?

The prevalence of Alzheimer's disease (AD) is projected to grow dramatically, but efforts to treat its progression have been unsuccessful. Fear of AD among older persons is greater than fear of cancer, and lingering worries about developing AD can be detrimental to well-being. Yet, much remains to be known about such worries and their precursors. This study, based on data from the Health and Retirement Survey, examines correlates of worry. Results of multivariate analyses show the following to be independent and significant correlates: present memory ratings, perceived changes in memory, personal familiarity with AD, belief that being a first-degree relative of someone with AD heightens the chance of developing AD, and age. Interaction analyses show that memory ratings and perceived changes in memory functioning are associated with worry regardless of personal familiarity. These findings will enable practitioners to identify patients and clients at risk of being worried about getting AD.
