Several years before a diagnosis of moderate cognitive impairment, older people may experience a lessened sense of purpose along with a sense of pessimism about their personal growth, a new study has found.
The study subjects were part of the Rush Memory and Aging Project, a long-term effort that began in 1997 at Rush University in Chicago to identify genetic and environmental factors in the development of Alzheimer’s disease. Their data has been used in more than 300 studies looking at aspects of aging, ranging from an investigation into the effects of egg consumption on dementia risk to a study of the relationship between loneliness and physical activity in older adults.
