Boost Your Brain Power

If you use the internet every day, you may be improving your brain power.  As Judy Fortin reports, drinking alcohol may have the opposite effect.  

Are you a Google fanatic or a Yahoo junkie?  You might be doing more for yourself than finding bargains online.According to UCLA scientists, computer-savvy middle-aged and older adults seem to trigger a part of their brains that controls reasoning, when they search online. 

Doctors say that can help the brain function better as we age.  Researchers worked with older volunteers.  Half were familiar with the internet.  The other half was not. 

Those who knew how to search online had more activity in the front part of the brain, which controls decision making and complex reasoning then those who didn't know how to work a search engine. 

And it may be good for heart in moderation, but not necessarily for your brain.  According to a new study out of the archives of neurology, the more alcoholic drinks you consume, the smaller your brain gets, which can affect your thinking and memory.

Neuroscientists looked at more than 1,800 people's brains and their drinking habits. Overall, the more alcohol consumed, the smaller the brain volume, with non-drinkers having the highest brain volume, especially in women. In men, only those who had 14 or more drinks a week seemed to experience significant brain shrinkage.
