Here's a strange one for the books: Science has taken notice that a really, really LARGE proportion of schizophrenic patients smoke. In fact, Scientific American Mind reports that an average of 85% of schizophrenic patients smoke cigarettes compared to only 20% in the general population. Many schizophrenics also appear to have abnormal thermoregulation, an impaired ability to understand body language, an inability to perceive an optical illusion called "the hollow mask illusion," an impaired ability to produce a brain protein known as the muscarinic M1 receptor, and an abnormally large number of genetic mutations known as CNV's or "copy number variations."

Speaking Of weight loss and exercise... Those who like their booze also like their nicotine. People who drink to excess also tend to be chronic smokers, and a new report suggests the combination of the two might prove more toxic than either one alone. a small study found chronic smoking + alcohol dependence = increased severity of brain damage. The frontal lobes (short-term storage sites) turn out to be the most damaged. A separate study used rats to show that alcoholism and excessive food intake may share the same chemical pathways in the brain. Forbes has the HealthDayNews report that focuses mainly on the smokes, MSNBC looks more at the eats. They also have an interesting Addictions Sections. Could it be that some folks are just prone to addictions and everyone settles on something different?
