Research examines link between aging, memory loss CMAJ 1997;157:503 © 1997 Canadian Medical Association A research team headed by Dr. Cheryl Grady of Toronto's Baycrest Centre for Geriatric Care is studying the neurobiologic basis for memory reduction. Using positron emission tomography, the team is measuring "regional" blood flow in young and older subjects while they learn and recognize material presented visually. The research concentrates on "episodic memory," which involves remembering events of daily life such as names, appointments and recent conversations; older people often experience memory deficits in these areas. Grady hopes the research will show that providing seniors with an effective learning strategy will improve their memory and lead to activation of additional brain areas during learning and retrieval.
