Many dementia patients have anhedonia, the loss of desire to seek pleasure, which causes a diminished quality of life; this research could open new doors for treating anhedonia in dementia.

Aging affects the brains' stem cells and blood vessels differently in males and females, underscoring the importance of addressing sex in stem cell research and treatment for age-related brain diseases.

Boosting NAD+ levels with NMN improves the health and integrity of both the cerebral blood flow system and the brain as a whole, leading to neurovascular rejuvenation in a group of aged mice.

Supplementing with NMN prevented the loss of muscle mass in mice by enhancing the function of their mitochondria — the energy powerhouses of our cells that tend to decline in function with age.
