Study utilizes integrative approach to probe biology of bipolar disorder

The more that we understand the brain, the more complex it becomes. The same can be said about the genetics and neurobiology of psychiatric disorders. For "Mendelian" disorders, like Huntington disease, mutation of a single gene predictably produces a single clinical disorder, following relatively simple genetic principals. Compared to Mendelian disorders, understanding bipolar disorder has been extremely challenging. Its biology is not well understood and its genetics are complex.

Adolescent hypomania does not predict bipolar disorder

Results from a Swedish study show that only a small proportion of depressed adolescents with hypomania spectrum episodes will develop bipolar disorder in adulthood.

Specific episode triggers in young adults with BD identified

Falling in love has the highest specificity for triggering manic/hypomanic episodes in young adults with bipolar disorder, while stressful life events has the highest specificity for triggering depressive episodes, researchers report.

Mechanism for chemotherapy resistance identified

Researchers have identified that chemotherapy induces subsequent treatment resistance through damaging healthy tissue, which in turn secretes novel factors that sustain the growth of residual tumor cells.

Two major classes of brain cells repress neural activity in specific mathematical ways

The brain has billions of neurons, arranged in complex circuits that allow us to perceive the world, control our movements and make decisions. Deciphering those circuits is critical to understanding how the brain works and what goes wrong in neurological disorders.
