The latest report from a 30-year study of families at high- and low-risk for depression reveals that the offspring of depressed parents have a higher risk for depression, morbidity and mortality that persists into middle age. [More]
Researchers find link between BPD and risk of STI/HIV in male inmates

Researchers find link between BPD and risk of STI/HIV in male inmates

Sexually transmitted infections (STI), including HIV, disproportionately affect incarcerated populations. In 2010, over 90% of the inmates living with HIV in U.S. prisons were men and the prevalence of STIs such as chlamydia, gonorrhea, and syphilis, continues to be much higher among male inmates as compared to the U.S. population at large.

Increasing ghrelin levels during hunger can negatively affect decision making capabilities

Increasing ghrelin levels during hunger can negatively affect decision making capabilities

Never make a decision when you are hungry. The hormone ghrelin - that is released before meals and known to increase appetite - has a negative effect on both decision making and impulse control. Such were the results of a recently conducted study at Sahlgrenska University. [More]
Researchers examine role of neural circuit in making decisions

Researchers examine role of neural circuit in making decisions

Choosing what shirt to buy, what to order for lunch or whether to go with the hearty red wine or the lighter white all involve assigning values to the options. A small brain structure plays a central role in the many decisions like this we make each day. But it hasn't been clear how a limited number of neurons in this small part of the brain can support an unlimited number of choices. [More]
High prevalence of depression alongside COPD can impact overall health, treatment effectiveness

High prevalence of depression alongside COPD can impact overall health, treatment effectiveness

Although there have been discussions about chronic obstructive pulmonary disease (COPD), a condition impacting 24 million Americans, and depression, there has been little research showing the impact depression has on patients with COPD. Two studies published in the April issue of the journal CHEST found one in four patients with COPD suffer from depressive symptoms, and if not treated, those symptoms can have a negative effect on their overall health and treatment effectiveness.

Depression, anxiety co-occur in bipolar disorder patients following mania

Depression, anxiety co-occur in bipolar disorder patients following mania

Adults with bipolar disorder are just as likely to develop anxiety as depression following an episode of mania, according to data from a national survey of more than 34,000 adults. This finding, published today in Molecular Psychiatry, may expand our understanding of bipolar disorder to include anxiety. [More]

Study shows cannabinoid type 2 receptor plays vital role in signal processing of the brain

The cannabinoid type 2 receptor - also called "CB2 receptor" - is a special membrane protein. Its function is to receive chemical signals that control cellular activity. "Until now, this receptor was considered part of the immune system without function in nerve cells. [More]
Nicotine metabolism linked with chronic alcohol abuse may contribute to poor smoking cessation rates

Nicotine metabolism linked with chronic alcohol abuse may contribute to poor smoking cessation rates

For smokers who are addicted to alcohol, chronic alcohol abuse may increase the rate of nicotine metabolism and contribute to poor smoking cessation rates. When smokers stop drinking the nicotine metabolism rates decline significantly, according to a study conducted by an international research team led by Roswell Park Cancer Institute. The research was a collaboration of scientists from Roswell Park, the University of California, San Francisco, and the Medical University of Silesia and Center of Addiction Treatment in Poland.
