Using marijuana a few times a week is enough to physically alter critical brain structures, according to a new study published Tuesday in The Journal of Neuroscience.
….The study found volume, shape and density changes in two crucial brain areas — the nucleus accumbens and the amygdala — involved with emotion and motivation and some types of mental illness. “This is a part of the brain you do not want to mess around with,” Breiter said.

94% of the population experiences unwanted, intrusive thoughts. So, if you are one to check whether your hands are clean, imagine your house might be on fire, or worry that the gas or propane has not been turned off, you are not alone.
Researchers clarify that the often devastating diagnosis of OCD is not a result of the thoughts, but the actions that follow or result from the thought.

The architecture of the autistic brain is speckled with patches of abnormal neurons, according to research partially funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health. Published in the New England Journal of Medicine on March 27, 2014, this study suggests that brain irregularities in children with autism can be traced back to prenatal development.
“While autism is generally considered a developmental brain disorder, research has not identified a consistent or causative lesion,” said Thomas R. Insel, M.D., director of NIMH. “If this new report of disorganized architecture in the brains of some children with autism is replicated, we can presume this reflects a process occurring long before birth. This reinforces the importance of early identification and intervention.”

Games like Flappy Bird and Candy Crush have helped many of us de-stress during long waits at the doctor’s office and crowded Metro rides. But what if an app could actually help with mental health?
….”What this game is doing is trying to train your attention toward the positive,” says Tracy Dennis, a professor of psychology at Hunter and the lead researcher behind the game. It’s modeled after a cognitive treatment for anxiety called attention-bias modification training, Dennis tells Shots. The idea is that if people can learn to ignore threatening stimuli and focus on the good, they’ll feel less anxious in stressful situations.

Poor integration of follow-up treatment into the continuum of psychiatric care leaves many individuals, particularly blacks, with poor-quality treatment.
….Rates of follow-up were generally low, particularly rates of adequate treatment, which were on average less than 26%. Outpatient treatment prior to inpatient care was a strong predictor of follow-up. After adjustment for need and socioeconomic status, the analyses showed that blacks were less likely than whites to receive any treatment or begin adequate follow-up within 30 days of discharge.

Teens call it “Special K,” a club drug that produces hallucinatory, out-of-body effects. But evidence is mounting that it’s also a fast-acting treatment for patients with severe depression.
The latest study shows that ketamine, an FDA-approved anesthetic, can act in a matter of days for some people who don’t respond to traditional antidepressants. Those drugs don’t work for 40 percent of patients.

With the Army’s disclosure that Army Spc. Ivan Lopez was being evaluated for post-traumatic stress disorder before he went on a shooting rampage Wednesday, there were once again questions about whether the Army could have prevented the violence at Fort Hood.
Experts in mental health say (even as more facts about Lopez emerge) that it’s highly unlikely the violence could have been predicted. Just raising that question, psychologists and psychiatrists say, shows how much Americans misunderstand the link between mental illness and violence.
One national survey in 2006 found that most Americans — 60 percent — believed people with schizophrenia were likely to be violent. But the vast majority of people with psychiatric disorders are not violent. In fact, another study found they are far more likely to be the victims of violence, and that 1 in 4 experience violence every year.

Researchers at the KU School of Medicine–Wichita are seeking adults, age 18-40, with schizophrenia to participate in a study of cognitive impairment associated with schizophrenia (CIAS).
The study is aimed at testing the theory that a virus is the cause of CIAS and is testing an anti-infective agent for this component of the disease.
Participants who qualify will receive study-related medications and procedures at no cost and will receive compensation for each visit.
Those interested in learning more about the study may call 316-293-1833.
Home treatment for schizophrenics overseen by local health workers is more effective than institutionalization, a recent large study in India has found.
The study — a clinical trial involving 282 patients at three sites in India — found that supervised home treatment, with limited hospitalization available, was somewhat better at reducing patients’ disability and much better at getting them to stay on their medications.
In poor countries with doctors overwhelmed by the struggle against physical diseases, mental disease is often ignored. In extreme cases, those with mental illness are simply kept in chains.
Many effective anti-psychotic drugs are too old to patent, so if they were available, even the poorest countries could offer some treatment, the study suggested. The health workers needed only six weeks of training.
Still, in the India study, home care was about $150 per patient more expensive than hospitalization or psychiatric care. Travel costs for the workers was a major factor.
