- Telephone-based Depression Treatment Program Effective While Cost Efficient
- October 16, 2009 • Science Update
Patients who receive structured, telephone-based support to manage their depression gain significant benefits with only moderate increases in health care costs compared to those who receive usual care, according to an NIMH-funded analysis published in the October 2009 issue of the Archives of General Psychiatry.
- Atlas Will Reveal When and Where Genes Turn On in the Brain
- October 06, 2009 • Science Update
When and where in the brain a gene turns on holds clues to its possible role in disease. For example, a recent study found that forms of a gene associated with schizophrenia are over-expressed in the fetal brain, adding to evidence implicating this critical developmental period.
- Schizophrenia Linked to Over-expression of Gene in Fetal Brain
- August 28, 2009 • Science Update
A gene called DISC1, (for “disrupted in schizophrenia”) has been a leading contender among possible genetic causes since it was implicated in schizophrenia in a large Scottish clan two decades ago. The DISC1 gene codes for a protein important for brain development, as well as for mood and memory – functions that are disturbed in schizophrenia. However, until now there have been few clues as to how DISC1 might increase risk for the chronic mental disorder.
- Schizophrenia and Bipolar Disorder Share Genetic Roots
- July 01, 2009 • Press Release
A trio of genome-wide studies – collectively the largest to date – has pinpointed a vast array of genetic variation that cumulatively may account for at least one third of the genetic risk for schizophrenia. One of the studies traced schizophrenia and bipolar disorder, in part, to the same chromosomal neighborhoods.
- Much Touted “Depression Risk Gene” May Not Add to Risk After All
- June 16, 2009 • Press Release
Stressful life events are strongly associated with a person’s risk for major depression, but a certain gene variation long thought to increase risk in conjunction with stressful life events actually may have no effect, according to researchers funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health. The study, published in the June 17, 2009, issue of the Journal of the American Medical Association, challenges a widely accepted approach to studying risk factors for depression.
