A new German study challenges the theory that cognitive problems increase with age.
Researchers used digital simulation models to compare how older and younger brains work to retrieve a word.
They found the fact that older people tend to know more words accounted for more than 75 percent of the difference in scores on a cognitive test. Researchers say the older mind may not be slower, but rather more full.
Experts say the findings aren't likely to reverse the years of research that shows memory and processing skills decrease with age, but it does raise questions about how severe those declines are.
