Gulf War and Health, Volume 7: Long-Term Consequences of Traumatic Brain Injury
Summary and Conclusions Aggressive Behaviors
The committee concludes, on the basis of its evaluation, that there is sufficientevidence of an association between TBI and subsequent development of aggressivebehaviors. Additional evidence that aggression is associated with TBI primarilywhen frontal cortical lesions are sustained is consistent with a large literatureassociating frontal lobe damage with loss of behavioral control.
Alcohol and Drug Abuse
The committee concludes, on the basis of its evaluation, that there islimited/suggestive evidence of an association between TBI and decreased drug andalcohol use, as compared with preinjury levels, in the 1–3-year period following theTBI.
The committee concludes, on the basis of its evaluation, that there islimited/suggestive evidence of an association between moderate or severe TBI andpsychosis. However, even if the TBI is severe, the psychosis does not appear duringthe first post-TBI year, but rather, becomes apparent in the second and third post-TBI years.
