Research: Cognitive Impairment Could Lead to Alzheimer’s

Almost two-thirds of American senior citizens with Alzheimer’s disease are women, according to research.

As women enter these ranks, their chances of developing Alzheimer’s disease are reportedly much greater than that for men. And women with mild cognitive impairment (MCI), a typical condition of Alzheimer’s disease, have been found to decline in cognition two times faster than men with MCI, according to research reported at the 2015 Alzheimer’s Association International Conference.

MCI typically involves a slight but noticeable and measurable decline in cognitive abilities, including memory and thinking skills, but the changes are not yet severe enough to interfere with daily life or independent function.

With this information, researchers from the Center for Brain Health at The University of Texas at Dallas are attempting to identify a potential biomarker that could offer a more complete picture of who is most at risk for developing Alzheimer’s.

Sizzling Temps Can Pose Threats to Seniors

Summer weather can pose special health risks to older adults and people with chronic medical conditions. It is critically important that the elderly, especially those most susceptible to hyperthermia and other heat-related conditions, know how to safeguard against these threats. 

Hyperthermia is elevated body temperature caused by a failure of the body’s heat-regulating mechanisms. Forms of hyperthermia include heat fatigue, heat syncope (sudden dizziness after prolonged exposure to the heat), heat cramps, heat exhaustion and heat stroke. Older adults can be at risk for experiencing these conditions, and this risk can increase with the combination of outside temperature, individual lifestyle and general health, according to the National Institute on Aging (NIA).

Some lifestyle factors that could increase this risk include not drinking enough fluids, living in housing without air conditioning, lack of mobility and access to transportation, overdressing, visiting overcrowded places and not understanding how to respond to hot weather conditions. 

Older people, especially those with chronic medical conditions and when an air pollution alert is in effect, should stay indoors in cooler spaces on hot and humid days. People without air conditioners should go to places that do have air conditioning (e.g., senior centers, shopping malls, movie theaters, libraries).
