Epilepsy drug gabapentin may reduce insomnia in recovering alcoholics

New Alzheimer's studies show advances against different treatment targets

Two studies related to experimental Alzheimer's therapies reported positive results today at the 2008 Alzheimer's Association International Conference on Alzheimer's Disease (ICAD 2008) in Chicago.

How anti-depressants and cocaine interact with brain

In a first, scientists from Weill Cornell Medical College and Columbia University Medical Center have described the specifics of how brain cells process antidepressant drugs, cocaine and amphetamines. These novel findings could prove useful in the development of more targeted medication therapies for a host of psychiatric diseases, most notably in the area of addiction.

Oxytocin hormone plays role in social bonding and maternal behaviors

Oxytocin was originally studied as the "milk let-down factor," i.e., a hormone that was necessary for breast-feeding. However, there is increasing evidence that this hormone also plays an important role in social bonding and maternal behaviors.

Obesity gene makes it harder to tell if you feel full

A study involving more than 3,000 children in Britain has found those with a gene linked to obesity find it harder than others to tell when they are full.

Previous estimates of levels of dementia in the developing world underestimated

Previous estimates of levels of dementia in the developing world may have substantially underestimated the problem, according to research published today. The findings suggest that policymakers in low-income and middle-income countries may need to re-examine the burden and impact that dementia places on their health services.

The stigma of being mentally ill

A mental health poll carried out in Britain has uncovered some shocking revelations.

Study shows promising results in deep brain stimulation for treatment-resistant depression

New data from a study of patients with treatment-resistant depression who underwent deep brain stimulation (DBS) in the subcallosal cingulate region (SCG or Cg25) of the brain shows that this intervention is generally safe and provides significant improvement in patients as early as one month after treatment. The patients also experienced continued and sustained improvement over time.

Obsessive compulsive disorder linked to activity in lateral orbitofrontal cortex

Cambridge researchers have discovered that measuring activity in a region of the brain could help to identify people at risk of developing obsessive compulsive disorder (OCD).

Coffee and smoking notorious at Alcoholics Anonymous meetings

More than one million Americans currently participate in the Alcoholics Anonymous (AA) program. While AA participants are reportedly notorious for their coffee drinking and cigarette smoking, very little research has quantified their consumption of these two products. Recent findings confirm that coffee and cigarette use among this population is greater than among the general U.S. population: most AA members drink coffee and more than half smoke.

Selective face processing abnormalities in parents of autistic children

Some parents of children with autism evaluate facial expressions differently than the rest of us - and in a way that is strikingly similar to autistic patients themselves, according to new research by psychiatrist Dr. Joe Piven of the University of North Carolina at Chapel Hill and neuroscientist Ralph Adolphs, Ph.D., of the California Institute of Technology.

Using genetics to improve traditional psychiatric diagnoses

Psychiatry has begun the laborious effort of preparing the DSM-V, the new iteration of its diagnostic manual. In so doing, it once again wrestles with the task set by Carl Linnaeus, to "cleave nature at its joints." However, these "joints," the boundaries between psychiatric disorders, such as that between bipolar disorder and schizophrenia, are far from clear. Prior versions of DSM followed the path outlined by Emil Kraeplin in separating these disorders into distinct categories. Yet, we now know that symptoms of bipolar disorder may be seen in patients with schizophrenia and the reverse is true, as well.

Shared gene expression alterations in schizophrenia and bipolar disorder

Both schizophrenia and bipolar disorder can be disabling conditions, and both present clinically with significant mood and psychotic symptoms. These two illnesses also share genetic variants that might be involved in the predisposition to both disorders.

D-cycloserine may improve behavioral therapy treatment for anxiety

Anxiety is a normal human response to stress, but in some, it can develop into a disabling disorder of excessive and irrational fears, such as obsessive-compulsive disorder, panic disorder, or posttraumatic stress disorder.
