Bipolar disorder

Bipolar disorder (previously known as Manic Depression) is a psychiatric diagnostic category describing a class of mood disorders in which the person experiences clinical depression and/or mania, hypomania, and/or mixed states.

The disorder can cause great distress among those afflicted and those living with them.

Bipolar disorder can be a disabling condition, with a higher-than-average risk of death through suicide.

The difference between bipolar disorder and unipolar disorder (also called major depression) is that bipolar disorder involves both elevated and depressive mood states.

Does Social Engagement Have a Genetic Root?

FORA.tv (May 13, 2013) Does Social Engagement Have a Genetic Root? California Academy of Sciences - California Academy of Sciences Innovation is critical for both individual and evolutionary success, but creative disruption requires taking risks. New research marrying the theory and methods of economics to cutting-edge neuroscience techniques - an emerging field known as NeuroEconomics - is making new discoveries about the biological processes that motivate us to take risks and create new solutions to unforeseen challenges. Dr. Platt will describe how the brain overcomes uncertainty to explore novel alternatives and create new knowledge. Parallel findings from humans, monkeys, rodents, and worms indicate that a common suite of underlying mechanisms has evolved to control the desire to explore. At one extreme, neuropsychiatric disorders like attention-deficit hyperactivity disorder, obsessive-compulsive disorder, and addiction, may arise from dysfunctional control of exploration. At the other, uniquely human faculties of creativity and technological innovation may reflect elaboration of this shared biological heritage controlling our desire to explore.
