 AB    The relationship between closed head injury and performance on
       neuropsychological (NP) tests was investigated in a group of intravenous
       drug users (IVDUs). Subjects with repeated head traumas involving loss
       of consciousness (LOC) performed worse than both a control group without
       LOC and reference group with only a single episode of LOC. There were no
       significant differences between the last two groups. Performance on
       tests of memory, attention, and motor performance was significantly
       worse in the group with repeated head injury. The average time since the
       last episode of LOC was more than 11 years. We conclude from these
       findings that a single episode of LOC does not result in significant
       cognitive impairment in this population. Two or more episodes, however,
       are more likely to produce chronic cognitive impairment.
