The Aging Brain

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?

The study of the neuroscience and neurobiology of aging continues to be an intensely active area of research. However, most of the research has been conducted on neurons. Neuroglia in the Aging Brain reviews the current knowledge of the supporting structure of the nervous system, the neuroglia, in aging.
