New Clues to Cognitive Decline

(…) The investigators looked at two types of brain cells: adult neural stem cells, responsible for maintaining supplies of neurons and their supporting cells, and forebrain neurons, vital for performing complex cognitive tasks.

In The EMBO Journal, they reported that NAD (Nicotinamide adenine dinucleotide) levels decreased with age in the mouse hippocampus, a vital region of the brain for cognition. The researchers then used genetic techniques to find out what would happen when NAD manufacturing is turned off in the adult neural stem cells of the mouse brain.

“Neural stem cells are very metabolically expensive, so you might expect them to be
