Men's Alzheimer's Risk Lowered with Active LifestyleCognitive and social activity in midlife may significantly reduce men's risk of dementia, say researchers in the medical journal Alzheimer's & Dementia. ![]() The study followed 147 male twin pairs for 28 years. Among the twins, higher cognitive activity scores predicted a 26 percent reduction in risk for developing dementia first. Twins who developed dementia first had significantly lower total cognitive activity scores than twins who did not develop dementia. Social Interaction KeyThe study found that reduced dementia risk was most strongly associated with participation in intermediate novel activities including home and family activities, visiting with friends and relatives, club activities (such as attending parties and playing card games), and home hobbies. "These activities might be indicative of an enriched environment, which has been shown in animal models to enhance the creation of new brain cells and promote brain repair," notes study author Michelle C. Carlson, Ph.D., at the Johns Hopkins Bloomberg School of Public Health. Two other categories of cognitive activities - novel and passive receptive - also reduced dementia risk, though not to the same degree as intermediate novel activities. Novel activities include reading, studying for courses, and extra work (overtime or other employment). Receptive activities include watching television, listening to radio, going to movies, or seeing theater, art, and music shows. "This fascinating study provides some of the first relatively strong evidence that cognitive activity, including social interaction, reduces dementia risk," says William Thies, Ph.D., of the Alzheimer's Association. "The results extend earlier twin study data that showed the beneficial impact of similar activities on Alzheimer's and dementia risk in women," he adds. Social Activity Aids Mental and Physical Health, TooA growing body of evidence suggests a link between low social activity and increased risk for Alzheimer's disease, and that mid- and late-life social activity is associated with better mental and physical health. "Overall, these findings suggest that engaging in activities that incorporate both cognitive and social activity might confer protection against Alzheimer's and dementia, particularly among those at elevated genetic risk for the disease," says Dr. Carlson. "These results can help inform future preventive interventions, especially because they point to a range of activities that individuals are likely to maintain, because they are rewarding, entertaining and engaging," she notes. Dr. Carlson says the findings "have immediate implications for a generation of male baby boomers approaching retirement. Approximately one third of many individuals' lives will be spent after retirement. The expansion of the human life span makes it imperative to identify lifestyle opportunities that increase health and add life to years." Always consult your physician for more information.

December 2008Men's Alzheimer's Risk Lowered with Active Lifestyle Social Activity Aids Mental and Physical Health, Too Alzheimer's Disease DefinedAlzheimer's disease is a progressive, neurodegenerative disease that occurs when nerve cells in the brain die and often results in the following:
With Alzheimer's disease, motor function is often preserved. When Alzheimer's was first identified by German physician, Alois Alzheimer, in 1906, it was considered a rare disorder. Today Alzheimer's disease is recognized as the most common cause of dementia (a disorder in which mental functions deteriorate and break down). An estimated 5 million Americans have Alzheimer's disease. According to the Alzheimer's Association, this number includes 4.9 million people over the age of 65, as well as 200,000 to 500,000 people younger than 65 who have early-onset Alzheimer's and other types of dementias. According to the Alzheimer's Association, the following are the most common symptoms of Alzheimer's disease:
