The neurocognitive effects of methamphetamine dependence

The cognitive sequelae of methamphetamine dependence are poorly understood, although some authors have linked methamphetamine use to persisting neurophysiological changes as well as motor and cognitive impairments. The current study seeks to outline the profile of neurocognitive impairments associated with methamphetamine dependence. Clients presenting for treatment for methamphetamine dependence are assessed for cognitive impairment on a battery of standardised neuropsychological instruments and results are compared to normative data. Results are discussed in relation to the nature and extent of cognitive impairment in methamphetamine dependence and the impact such impairments may have on treatment and rehabilitation
