  • Abstract
  • Look Inside

 We here report a 31-year-old man showing persistent marked behavioral disorders associat-ed with a small low density area in the head of the right caudate nucleus on CT scan. In the acute stage, he exhibited disinhibition, and then gradually became apathetic. While not able to cope with non-routine activities in daily life, his performance on neuropsychological testing for intelligence, memory, and “frontal lobe function” showed only mild deficit. SPECT scan revealed hypoperfusion involving the right frontal base as well as the right caudate nucleus, suggesting that his behavioral changes were due to extensive damage to both of these regions.
