Depression, lifestyle choices shown to adversely affect memory across age groups

Depression, lifestyle choices shown to adversely affect memory across age groups

IMG_0140Have trouble remember where you put your keys? Forgetting the names of familiar faces? A lack of physical activity, depression, high blood pressure and a variety of other health factors could be to blame, according to findings recently published in PLOS ONE.

In the study, researchers at the University of California, Los Angeles and the Gallup organization surveyed more than 18,000 people about memory and lifestyle choices previously shown to increase the risk of Alzheimer’s disease and dementia. PsychCentral reports:

Depression, low levels of education, physical inactivity, and high blood pressure increased the likelihood of memory complaints in younger adults (ages 18–39), middle-aged adults (40–59), and older adults (60–99), the researchers found.

Depression was the strongest single risk factor for memory complaints in all age groups.

Having just one risk factor significantly increased the frequency of memory complaints, regardless of age, according to researchers. Memory complaints rose when the number of risk factors increased.

Overall, 20 percent of those polled had memory complaints, including 14 percent of younger adults, 22 percent of middle-aged adults, and 26 percent of older adults.

For younger adults, stress may play more of a role, and the ubiquity of technology — including the Internet and wireless devices, which can often result in constant multi-tasking — may impact their attention span, making it harder to focus and remember.

Researchers hope the findings, and follow-up studies, better identify how health choices made earlier on may impact cognitive function at a later age and lead to interventions to lower the risk of memory loss.
