Researchers say people do not observe this slow reduction in mental ability until the loss affects their everyday activities. Denise Park led the new study.She directs the center for Aging and Cognition at the Institute for Social Research at the University of Michigan.Her team studied more than 350 men and women between the ages of twenty and ninety years.The study identified people in their middle twenties with memopf problems. She says young adults do not know they are forgetting things because their brains have more information than they need. But she says that people in their ten ties and thirties are losing memmT at the same rate as people in their sixties and seventies.
