Abstinence leads to rapid brain repair

Abstinence leads to rapid repair of gross brain damage seen in alcohol dependent persons, according to a review of neuroimaging studies by a group of Japanese researchers.

In uncomplicated alcoholic patients, a high incidence of cortical shrinkage and ventricular dilatation were reported using brain CT scans. In older alcoholics, prefrontal gray matter deficits were especially marked when compared with younger alcoholics. Reversibility of brain shrinkage is a common neuroimaging finding in patients with alcohol dependence.

Regrowth of shrunken brain areas was particularly vigorous during the first month of abstinence, the scans showed. Besides the gray matter, areas "with significantly greater recovery in abstainers were the temporal lobes, thalamus, brainstem, cerebellum, corpus callosum, anterior cingulate, insula, and subcortical white matter." Follow-up studies showed that the regrowth was not simply due to rehydration.

The study appeared in the Dec. 2007 issue of the Japanese Journal of Alcohol Studies and Drug Dependence. The abstract is here.

Toyota developing sober car

TOKYO (AP) — Toyota is developing a fail-safe system for cars that detects drunken drivers and automatically shuts the vehicle down if sensors pick up signs of excessive alcohol consumption, a news report said Wednesday.

Cars fitted with the detection system will not start if sweat sensors in the driving wheel detect high levels of alcohol in the driver's bloodstream, according to a report carried by the mass-circulation daily, Asahi Shimbun. More.
