Sadly, aging and cognitive decline go hand-in-hand.

In Big Think’s video “The Science of Brain Health and Cognitive Decline,” neuropsychiatrist and Nobel Prize recipient Eric Kandel explains how the brain changes as we age, as well as how we can help avoid memory loss.

Alzheimer’s Disease and Age-Related Memory Loss (ARML) are two kinds of cognitive decline that are associated with aging, but these two ailments operate very differently.

“The difference between Alzheimer's disease in the sense that it starts earlier, it starts in mid life; it involves a different part of the brain it starts in the dentate gyrus, Alzheimer's disease starts in the entorhinal cortex. And it is prevented. You can prevent it. And also to some degree you might be able to reverse it,” Kandel said in the video.

The acclaimed researcher explains that decline can be prevented through social interaction, cognitive involvement, taking on new skills, learning a foreign language, physical exercise, a good diet, and good overall health.

Mild cognitive impairment is linked to an increased risk of developing dementia or Alzheimer's disease.

Many recent studies have looked at age-related memory loss and scientists are working to reverse these effects.
