Program and Policy Implications
The Interaction of Genes, Behavior, and Social Environment
For most people, the probability of having a physical or mental disability increases with age, as does the number of ailments they might have at any time—particularly after age 70. Memory loss and other cognitive impairments are more likely with age and, in addition, the elderly tend to be more socially isolated. These changes may occur because of genes, behavior, the environment, or interactions among these factors. Understanding the nature of these interactions could be the key to designing effective public health and medical interventions to slow or even reverse the onset of mental and physical conditions associated with aging.
This e-newsletter highlights recent results from research that assesses the effects of interactions among genes, behavior, and the environment.
