Buzz associated with bipolar 'a double-edged sword'

Scientists investigating bipolar disorder invited participants to make safe or risky gambles as they spun the wheel in a game of roulette.

Brain activity was measured using a functional magnetic resonance imaging (fMRI) scan that monitors blood flow in the brain.

Professor Wael el-Deredy, from the University of Manchester, said in the journal Brain:

The greater buzz that people with bipolar disorder get from reward is a double-edged sword.

However, it comes at a cost; these same people may be swayed more by immediate rewards when making decisions and less by the long-term consequences of these actions.
