- Genes and Circuitry, Not Just Clinical Observation, to Guide Classification for Research
- Science Update
NIMH is launching a long-term project aimed at ultimately improving treatment and prevention by studying classification of mental illness, based on genetics and neuroscience in addition to clinical observation. The Research Domain Criteria (RDoC) project is not intended to replace psychiatry’s existing diagnostic system for practitioners and will proceed in an independent direction, said Bruce Cuthbert, Ph.D., Director of the NIMH Division of Adult Translational Research, who is directing the effort. By taking a fresh look – without preconceived categories – the project aims to improve the validity of classification for researchers.
- Same Genes Suspected in Both Depression and Bipolar Illness
- Science Update
Researchers, for the first time, have pinpointed a genetic hotspot that confers risk for both bipolar disorder and depression. People with either of these mood disorders were significantly more likely to have risk versions of genes at this site than healthy controls. One of the genes, which codes for part of a cell’s machinery that tells genes when to turn on and off, was also found to be over-expressed in the executive hub of bipolar patients’ brains, making it a prime suspect. The results add to mounting evidence that major mental disorders overlap at the molecular level.
