Older adults with obesity less responsive to memory training
To determine responsiveness to memory training the scientists followed cognition over 10 years, comparing trajectories of cognitive performance in older adults with obesity, overweight and normal weight who received the training and those who did not.

"These findings suggest that memory training is less beneficial for older adults with obesity but we really don' t know why," said Daniel O. Clark, PhD, lead author of the study. "There is growing evidence of a link between obesity status and brain function, including imaging studies reporting that obesity is associated with more rapid loss of hippocampal volume. So it' s possible that actual capacity for memory gains is less for older adults with obesity.
