A team of researchers says it has solved the longstanding puzzle of why a key protein linked to learning is also needed to become addicted to cocaine. Results of the study, published in the Aug. 1 issue of the journal Cell, describe how the learning-related protein works with other proteins to forge new pathways in the brain in response to a drug-induced rush of the “pleasure” molecule dopamine. By adding important detail to the process of addiction, the researchers, led by a group at Johns Hopkins, say the work may point the way to new treatments.

Ongoing studies suggest that using a mix of omega-3 fatty acid supplements and psychotherapy may be helpful for children with depression and a variation of bipolar disorder. The interventions could give doctors a safer alternative than current anti-depressant and mood disorder medications. While effective, many of these medications have serious side effects. The studies are the first of their kind to evaluate a dietary supplement coupled with talk therapy in a younger population with mood disorders.

One in four people who survive a stroke or transient ischemic attack (TIA) suffer from symptoms of PTSD within the 1st year post-event, and one in nine experience chronic PTSD more than a year later. The data, e-published by PLOS ONE, suggest that each year nearly 300,000 stroke/TIA survivors will develop PTSD symptoms as a result of their health scare.
Fights between siblings are so common they’re often dismissed as simply part of growing up. Yet a new study finds that sibling aggression is associated with significantly worse mental health in children and adolescents. In some cases, effects of sibling aggression on mental health were the same as those of peer aggression.

They then worked with a group at the Scripps Research Institute who had previously developed the Oprl1-targeted drug to examine its effects on fear memory modulation.
