Abstract: (2586 Views)
Objective: The purpose of this study was to investigate cognitive functions (attention, working memory and executive functions) in patients with methamphetamine-induced psychosis (MIP) in comparison with a healthy control group.
Method: This was a cross sectional study of 30 patients with MIP and 30 normal and demographically matched subjects. The selection of both samples was performed through purposeful sampling. Stroop Test, Wisconsin Cards Sorting and Wechsler Memory Scale were used to assess the subjects.
Results: Patients with MIP showed more deficits in attention, working memory and executive functions than the control group. Furthermore, patients with MIP showed an improvement in attention and working memory in the second assessment. Executive functioning also improved to some extent.
Conclusion: Patients with MIP have more cognitive dysfunctions than non-psychotic methamphetamine users. According to the findings of the post test, abstinence and treatment with antipsychotics can, at least in the short term, improve cognitive functioning in patients with MIP.
