The Neurocritic has fallen a little behind the times and is getting caught up on all the latest sensationalistic neuronews. It seems that Tuesday, November 21, 2006 was a conspicuously breathy day for press releases listed at HealthOrbit.ca (which, by the way, now charges for access to links that you can easily find through Google News):
Wow! All you researchers in gerontology and cellular senescence can retire now! Just what is behind this miracle cure?
Exercise shown to reverse brain deterioration brought on by agingCHAMPAIGN, Ill — The wait for an anti-aging treatment is over, according to cognitive neuroscientists and kinesiologists at the University of Illinois at Urbana-Champaign.

While not as effortless as popping a pill, the treatment – in the form of moderate exercise – may be a simple and effective way to reverse age-related brain deterioration.Oookaay...
In a study published in the November issue of the Journal of Gerontology: Medical Sciences, psychology and neuroscience professor Arthur F. Kramer and his collaborators show that moderate exercise increases brain volume in older adults.

But the research of UCLA neurology professor George Bartzokis, M.D., has already shown that myelin problems are implicated in diseases that afflict both young and old — from schizophrenia to Alzheimer's.
