Alcohol is one of the most commonly abused substances, and men are up to twice as likely to develop alcoholism as women. Until now, the underlying biology contributing to this difference in vulnerability has remained unclear. A new study published in Biological Psychiatry reveals that dopamine may be an important factor.
Mental disorders in children are often difficult to identify due to the myriad of changes that occur during the normal course of maturation. For the first time, researchers at the National Institute of Mental Health have reported on the prevalence data on a broad range of mental disorders in a nationally representative sample of U.S. adolescents, which show that approximately one in five children in the U.S. meet the criteria for a mental disorder severe enough to disrupt their daily lives.
There is growing evidence that two neurotransmitters – dopamine and glutamate – are abnormal in people with psychotic illness, including schizophrenia. Among many other things, these chemicals play a role in cognitive functions, such as memory, learning, and problem-solving.
n groups with high rates of posttraumatic stress disorder (PTSD), such as the survivors of the Nazi Death Camps, the adjustment problems of their children, the so-called Second Generation, have received attention by researchers. Studies suggested that some symptoms or personality traits associated with PTSD may be more common in the Second Generation than the general population.
There is new evidence that people can learn to control the activity of some brain regions when they get feedback signals provided by functional magnetic resonance brain imaging (fMRI).
Researchers at King’s College London’s Institute of Psychiatry describe a successful personality-based intervention for substance abuse delivered by teachers in the September 2010 issue of the Journal of the American Academy of Child and Adolescent Psychiatry.
The notion that cutting or burning oneself could provide relief from emotional distress is difficult to understand for most people, but it is an experience reported commonly among people who compulsively hurt themselves.
The hormone oxytocin has come under intensive study in light of emerging evidence that its release contributes to the social bonding that occurs between lovers, friends, and colleagues. Oxytocin also plays an important role in birth and maternal behavior, but until now, research had never addressed the involvement of oxytocin in the transition to fatherhood.
