      This only seems to confirm my view that bipolar isn't
      a separate condition. Problems with nonverbal communications
      is central to the autism-spectrum, and interpreting facial
      expressions is an important part of nonverbal communications.
      Therefore, there seems to be a large overlap between the autism
      spectrum and bipolar. Other things that seems to confirm this
      is similarities to AD/HD. Even if the activity-patterns of
      AD/HD and bipolar are on different time-scales, they
      could still share the same etiology.

      These differences are compatible with inheritance of
      a different set of facial expressions that is not
      fully compatible with the majority in our species.
