Background and Aims:

As a result of long-term heroin abuse we can see impairment of cerebral structures that leads to specific deficits in cognitive and conative area. Reaction time(RT) is an interval between reception of the certain stimulus and movement execution, as a response to received stimulus. It includes unharmed perceptive functions, attention, concentra- tion and psychomotor coordination. The aim of this study was to evaluate the effect of heroin abuse on RT.

Method:

90 heroin addicts, divided in tree groups, regarding to abuse duration, were included in study. Reaction time was estimated by specially designed computer program, based on the modified Donders's model of reaction time.

Results:

Averige RT increase in corelation to duration of heroin addiction

Results have shown that heroin abuse is connected with the prolongation of simple and choice reaction time, in both visual and auditory modality. Also, there is significant relation between prolongation of choice reaction time and duration of heroin abuse.

Conclusion:

Heroin abuse duration is related to decrease of psychomotor speed and impairment of psychomotor coordination.
