But there are several things people with depression can try to help return themselves to their usual level of cognitive functioning.

Q. Do you think we'll ever be able to prevent Alzheimer's disease?

Q. I heard regular aerobic exercise is better for the brain than strength exercises (resistance training). Is that true?

A. The study you probably heard about involved rats, not humans. The rats were made to engage each day in sustained aerobic exercise, high-intensity interval training, or resistance training, or they were allowed to just be sedentary. At the end of the study, the researchers examined the rats' brains. The rats doing regular aerobic exercise had more brain cells than the sedentary rats. However, the rats made to perform high-intensity interval training or the ones doing resistance training did not have more brain cells than the sedentary rats.
