Cellular Senescence And Brain Aging

Geriatric medicine

Features that characterize the aging process include the gradual accumulation of cell damage after prolonged exposure to oxidative and inflammatory events over a lifetime. In addition to the accretion of lesions, the intrinsic levels of pro-oxidant and aberrant immune responses are elevated with age. These adverse events are often further enhanced by the chronic and slow progressing diseases that characterize the senescent brain and cardiovascular system.

We’re all getting older every day, and scientific research has shown that starting in our twenties, some brain functions begin a linear decline. Even if we avoid diseases such as Alzheimer’s and Parkinson’s, parts of the brain inevitably shrink, replicating cells become damaged, and fluid processing skills such as multitasking and episodic memory worsen. But is old age all doom and gloom? Are we destined for senescence once we’re barely out of adolescence?
