Abstract

  A case with so-called discourse problem by Ponsford is reported.
  An unemployed man aged 37 yrs showed the characteristic symptoms besides attention disturbance, memory impairment, and executive dysfunction as sequelae of traumatic brain injury.
  The brain lesions were found in both dorsomedial part of prefrontal area, lateral part of right temporal lobe and right amygdale. The characteristic symptoms observed in this case are as follows : round-about speech ; unsuitable topics of conversation; disregard of unpleasantness of listeners. It appeared that his interpersonal relation ship disorder was attributable to the symptoms. We assumed that executive dysfunction, difficulty in perception of non-verbal message from others, and control loss of speech manner contributed to the symptoms.
