A story about research that focuses on cognitive impairment in the elderly features Peter Lichtenberg, director of Wayne State's Institute of Gerontology. Given the importance that quality of education may play in cognitive functioning later in life, Lichtenberg has concentrated his research on developing more accurate tests for people who often didn't get a chance to receive a good education when they were young. Lichtenberg was encountering seniors, mostly African-American patients, who had suffered injuries such as leg fractures as a result of falls, often in their homes. He was concerned that physicians treating the seniors didn't seem to be catching evidence of cognitive decline and dementia, even though the seniors' injuries from falls and walking problems were often connected to their cognitive health. Studies authored by Lichtenberg are cited in the article.
