Abstract:
A 78-year-old housewife with major depression developed a right-sided infarction in the territory of the middle cerebral arteries, followed by acute post-stroke mania. Comparison between pre- and post-stroke SPECT scans demonstrated a unique pattern of left orbitofrontal hyperperfusion with extensive right frontal hypoperfusion. A functional imbalance between right and left orbitofrontal cortices may be important in mania.
