Book excerpt: Habits such as regular exercise are well known to be linked to better health in older adults. Far less is understood about behaviors that contribute to the optimally aging mind. This may be a reason why only about 25% of elders meet the standards for optimal cognitive aging. The Aging Intellect describes more than a dozen specific characteristics that distinguish older people who remain cognitively vigorous from the majority who are aging normally or are at risk for cognitive impairment. In addition, this book provides professionals with evidence-based recommendations that can help their aging patients and clients minimize the effects of predictable cognitive changes and more fully use their mental abilities. The Aging Intellect is also written for people of all ages interested in maximizing their cognitive vigor. Dr. Powell has encouraging words for those who know they are not aging optimally, but are willing to modify one or two habits that can improve their mental powers. Richly illustrated with clinical examples and case studies, The Aging Intellect includes topics rarely discussed in book form. specifies lifestyle habits and attitudes linked to three levels of cognitive aging: optimal, normal, and at risk for cognitive impairment describes evidence based strategies that minimize mental decline warns of normal cognitive changes that increase the chances of elders making poor financial decisions identifies intellectual qualities that strengthen with age.
