Bipolar disorder: Mind-body connection suggests new directions for treatment, research
The study begins with the understanding that areas of the brain that are critical for motor control, mainly the cerebellum, basal ganglia and brain stem, also aid in mood regulation and are areas where abnormalities often are found in people with bipolar disorder. Postural sway -- a measure of the degree of endless adjustments people make in an attempt to stand still -- is considered a sensitive gauge of motor control that likely is affected by these abnormalities.

In the study, participants who had bipolar disorder displayed more postural sway, particularly when their eyes were closed, than study participants who had no psychological disorders. The troubles, which involved the study participants' proprioception, or ability to process non-visual sensory information related to balance, were not affected by their mood or the severity of their disorder.

"It appears that people with bipolar disorder process sensory information differently and this is seen in their inability to adapt their movement patterns to different conditions, such as eyes open vs. eyes closed or feet together vs. feet apart," said Hong, whose research focuses on how humans control motion. "The different conditions will cause people to use the information their senses provide differently, in order to allow them to maintain their balance."
So maybe this is why I can't keep my balance with my eyes closed and dread ever being given a roadside sobriety test?
