None of us can stand perfectly still. No matter how hard we try, our bodies constantly make small adjustments, causing us to sway slightly as we stand. A new study finds that people with bipolar disorder tend to sway more than those who are unaffected, which may lead to new ways to treat and diagnose the illness.

Indiana University psychologist Amanda Bolbecker points out that the cerebellum, located at the base of the brain, helps to regulate movement and is also involved in emotional reactions, such as fear and pleasure. In addition, the cerebellum connects to other parts of the brain linked to cognition, mood regulation and impulse control, three areas in which patients with bipolar disorder often have difficulties. If the cerebellum is damaged at the cellular level, it may create problems with both mood and motor control.
