Science News About Bipolar Disorder

Scientists have deciphered the molecular structure of a widely-prescribed antipsychotic docked in its key human brain receptor. The discovery may hold clues to designing better treatments for schizophrenia, bipolar disorder and other mental illnesses.

Using a molecular method likely to become widely adopted by the field, researchers have discovered brain circuitry essential for alertness – and for brain states more generally.

Two standard medications for bipolar disorder were effective in controlling symptoms at doses tailored to older people in a clinical trial of treatment in adults over age 60.

“An NIH/NIMH lifer” reveals how his Asian American family successfully coped with severe mental illness compounded by discrimination.

Three types of symptoms emerged as powerful predictors of whether a youth with one parent with bipolar disorder will go on to develop the disorder, according to a new NIMH-funded study of 391 at-risk youth.

Genome-Wide Study Yields Markers of Lithium Response

Three biomarker-based categories, called “biotypes,” outperformed traditional diagnoses, such as schizophrenia and bipolar disorder with psychosis, in sorting psychosis cases into distinct subgroups on the basis of brain biology

Risk genes for different mental disorders work through same pathways

A drug being studied as a fast-acting mood-lifter restored pleasure-seeking behavior independent of – and ahead of – its other antidepressant effects.

Researchers have shown in patients’ cells how a rare mutation in a suspect gene disrupts the expression of dozens of other genes underlying neural connections.

The hippocampus houses learning and memory—specifically the storage of knowledge of who, what, where, and when. Using a special transgenic mouse, researchers have now pinpointed a hippocampal region called CA2 that is important for social memory, the ability of animal to recognize another of the same species. Understanding this region could be useful in understanding and treating disorders characterized by altered social behaviors such as schizophrenia, bipolar disorder, and autism.
