The ability of cannabis to produce psychosis has long been an important public health concern. This concern is growing in importance as there is emerging data that cannabis exposure during adolescence may increase the risk of developing schizophrenia, a serious psychotic disorder. Further, with the advent of medical marijuana, a new group of people with uncertain psychosis risk may be exposed to cannabis. For these reasons, it would be valuable if a biological test could be developed that...

fMRI study finds neural correlates to support cognitive model Researchers at the University of Bergen in Norway have found new support for their theory that cannabis use causes a temporary cognitive breakdown in non-psychotic individuals, leading to long-term psychosis. In an fMRI study published this week in Frontiers in Psychiatry, researchers found a different brain activity pattern in schizophrenia patients with previous cannabis use than in schizophrenic patients without prior...

There are a growing number of clues that immune and inflammatory mechanisms are important for the biology of schizophrenia. In a new study in Biological Psychiatry, Dr. Mar Fatjó-Vilas and colleagues explored the impact of the interleukin-1β gene (IL1β) on brain function alterations associated with schizophrenia. Fatjó-Vilas said that "this study is a contribution to the relatively new field of 'functional imaging genetics' which appears to be...

A new genetic study in Biological Psychiatry One of the biggest challenges in psychiatric genetics has been to replicate findings across large studies. Scientists at King's College London, Institute of Psychiatry have now performed one of the largest ever genetic replication studies of bipolar affective disorder, with 28,000 subjects recruited from 36 different research centers. Their findings provide compelling evidence that the chromosome 3p21.1 locus contains a common genetic risk...

Fewer than 100 people in the world are known to be affected by a movement disorder called rapid-onset dystonia-parkinsonism (RDP), but its symptoms are life-changing. Seemingly normal young people are suddenly and dramatically unable to control movement of their arms or legs and have trouble speaking or swallowing. A normal life is nearly impossible. RDP is caused by a genetic mutation (ATP1A3) that often runs in families. Now Wake Forest Baptist Medical Center researchers believe that...

Biomarkers help pinpoint mechanisms, predict outcomes -- NIH studies Scientists have discovered a biological marker that may help to identify which depressed patients will respond to an experimental, rapid-acting antidepressant. The brain signal, detectable by noninvasive imaging, also holds clues to the agent's underlying mechanism, which are vital for drug development, say National Institutes of Health researchers. The signal is among the latest of several such markers, including...

The relationship between untreated severe mental illness and violence is well-established. At least 10% of homicides and a larger percentage of rampage murders involve a suspect who is mentally ill, according to the Treatment Advocacy Center. Arlington, VA (PRWEB) July 20, 2012 Almost inevitably after the massacres in Tucson, at Virginia Tech and elsewhere, the rampage that left 12 dead and scores wounded early Friday in Aurora, Colorado, raises questions about the relationship of severe...

  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
