- Genes may interact with obstetric complications to boost schizophrenia risk
01-14-2008 · EurekAlert!
Researchers have proposed that such birth traumas may interact with certain gene variants to increase risk for the illness. Now, a new study by researchers at the National Institute of Mental health has identified specific genes involved in such interactions. Obstetric complications appeared to increase the impact of versions of genes affected by loss of oxygen or blood supply to the brain, as often occurs in such birth traumas.

- Researchers discover possible markers for mental illness
12-03-2007 · EurekAlert!
Researchers have discovered natural genetic differences that might help predict the most effective antipsychotic drugs for particular patients with mental disorders such as schizophrenia, Parkinson's and drug addiction. They found the differences in the gene for a molecule called the dopamine D2 receptor, a protein present on brain cells that are sensitive to the neurotransmitter dopamine.

- Common gene version optimizes thinking -- but with a possible downside
02-08-2007 · EurekAlert!
Most people inherit a version of a gene that optimizes their brain's thinking circuitry, yet also appears to increase risk for schizophrenia, a severe mental illness marked by impaired thinking. The seeming paradox emerged from the first study to explore the effects of variation in the human gene for a brain master switch, DARPP-32. The gene impacts the way two key brain regions exchange information, affecting a range of functions from general intelligence to attention.

- Severe mental retardation gene mutation identified
03-20-2007 · EurekAlert!
Researchers have identified a novel gene mutation that causes X-linked mental retardation for which there was no previously known molecular diagnosis, according to an article to be published electronically on Tuesday, March 20, 2007, in the American Journal of Human Genetics.

- Deal or no deal? Need for immediate reward linked to more active brain region
12-19-2006 · EurekAlert!
How people might play the popular game show -- whether they'd accept an offer for quick cash or hold out for the chance to win $1 million -- probably has less to do with what’s inside each briefcase than what's inside each contestant's brain, suggests a study. While researchers didn't study players of the game, their research in normal adults provides new insight about reward-based decision making and may have implications for understanding and treating addiction.

- Drugs for Parkinson's disease may ease stroke-related disability
04-10-2007 · EurekAlert!
Scientists have untangled two similar disabilities that often afflict stroke patients, in the process revealing that one may be treatable with drugs for Parkinson's disease. Researchers at Washington University School of Medicine in St. Louis showed that stroke damage in a brain region known as the putamen is strongly linked to motor neglect, a condition that makes patients slow to move toward the left side.

- Researchers suggest new direction for development of psychotropic drugs
12-04-2006 · EurekAlert!
A panel of academic, industry and government representatives, presenting at the ACNP Annual Meeting, concluded that several factors have impeded the development of novel treatments for mental illness, including: incomplete understanding of the impact of mental illness on the brain; continued skepticism of results from animal models for certain disorders, and an outdated paradigm of treatment and the industry preference toward so-called "me-too" drugs.
