Nicotine and the Aging Brain


I’m Kylie Badgley with today’s health news. Nicotine, usually associated with smoking,
always gets a bad wrap, but researchers from Texas A&M University found that nicotine may
help protect the brain. The protective effect seems to be connected
to nicotine’s ability to suppress the appetite. The lead author said in a press release that
smoking does have neurological effects, but to what effect is unclear. In this study, researchers used mice to test
the effects of nicotine. There were no obvious behavioral changes such
as anxiety, but the mice in the group with the highest concentration ate less, gained
less weight and had more brain receptors for nicotine. The increase in receptors indicates nicotine
is getting into the brain. The next step in the research is to evaluate
aged animals to see whether lower weight corresponds to less brain degeneration. Lead study author wants to make it very clear
that Quote… “we’re not encouraging people to smoke. Smoking results in so many health problems
that any possible benefit of the nicotine would be more than canceled out.” More research is need before suggesting anyone
change their behavior. For more information about the negative effects
of smoking visit dailyRxnews.com and be sure to talk to your doctor if you need help to
quit smoking. For dailyRx, I’m Kylie Badgley.
