Abstract:

Severe influences on cognitive function caused by chronic drug abuse, such as attention, have drawn public attention. In present review, common attentional tasks were introduced, and behavioral effects on attention, caused by chronic abuse of opioid or psychomotor stimulants, were analyzed. The majority of the studies showed the negative effects on attentional function caused by opioid or psychomotor stimulants abuse, especially for the psychomotor stimulants. As for cocaine, male abusers showed poorer attention compared with their female counterparts. Cocaine-induced impairments may be concealed for abusers during their cocaine use, but may resurface during their abstinence. MDMA and cannabis abuse will significantly impair abusers' attention; while methamphetamine abusers may recover from their attention defects to some degree after certain lengthy time of abstinence.

Key words: chronic drug abuse, attention, opioid, psychomotor stimulants
