Researchers find alcoholics display abnormal brain activity when processing facial expressions
Researchers from Boston University School of Medicine (BUSM) have found that individuals who have a long history of alcoholism, but who have been abstinent for at least a month up to many years, showed abnormal brain activity when looking at facial expressions of others. The findings, which appear in the August 11 issue of Alcoholism: Clinical and Experimental Research, confirms that alcoholics suffer from abnormalities in parts of the brain that control emotional perception and memory.

New class of compounds discovered for potential Alzheimer’s disease drug, Penn study finds
A new class of molecules capable of blocking the formation of specific protein clumps that are believed to contribute to the dementia of Alzheimer’s disease (AD) patients has been discovered by researchers at the University of Pennsylvania School of Medicine. By assaying close to 300,000 compounds, they have identified drug-like inhibitors of AD tau protein clumping, as reported in the journal Biochemistry. more
Wide range of mental disorders increase the chance of suicidal thoughts and behaviors
Although depression is the mental disorder that most people associate with suicidal behavior, a new study reveals that a wide range of mental disorders increase the odds of thinking about suicide and making suicide attempts. Whereas depression is indeed one of the strongest predictors of suicidal thoughts across many different countries, it is disorders characterized by anxiety and poor impulse-control that best predict which people act on such thoughts—especially in developing countries, says a multi-country study published in this week's open access journal PLoS Medicine.
