Bipolar disorder is a severe psychiatric illness associated with profound impairment in social and occupational functioning. Several conditions, including psychiatric disorders, have been associated with a decreased cranial rhythmic impulse (CRI). In this case report, a 20-year-old man with a recent manic episode is found to have a normal cranial rhythmic impulse, which is found to be decreased following resolution of the manic episode. This case illustrates the potential that a relative CRI increase in bipolar disorder may be a sign of an active manic state.
