Alprazolam is used as an anxiolytic drug for generalized anxiety disorder and it has been reported to produce sedation and anterograde amnesia. In the current study, the Cambridge Neuropsychological Test Automated Battery (CANTAB) software was used to test the effect of chronic intake of alprazolam in healthy volunteers. The selected testing battery consisted of the Paired Associates Learning (PAL) and Delayed Matching to Sample (DMS) tests for memory, Rapid Visual Information Processing (RVP) for attention, and Choice Reaction Time (CRT) for psychomotor performance. The testing was done twice: before starting the treatment and after the completion of the treatment. In the current investigation, statistically significant impairment of visual memory in one parameter of PAL and three parameters of DMS were found. However, one parameter of RVP was improved and no difference was observed in CRT.
