The results obtained should be confirmed in a larger cohort. The QMT is a quick, precise and effective computerized method to measure reaction time, attention and subliminal processing. It may be concluded that reaction time is the most vulnerable cognitive parameter in alcohol dependent patients. The alcohol ependent patients performed worse in the following parameters of QMT: mean reaction time for incorrect reactions (Test 2), mean reaction time for correct target reactions (Test 4), reaction time in subliminal priming task (Test 5) and number of correct responses in part 2 and 3 of Test 3. The study included 16 male patients hospitalized at the Psychiatric Clinic of the University Hospital No 1 in Bydgoszcz with an alcohol dependency diagnosis and 16 healthy males. In order to address cognitive domains which are reported to be vulnerable to the alcohol abuse we constructed the computerized cognitive battery QMT – Quick Mind Testing. Chronic use of alcohol has been consistently associated with cognitive impairments including attention mechanisms, information processing, visual - spatial perception, working memory, problem solving and decision making. It was suggested that continued substance involvement in adolescence leads to greater neurocognitive difficulties, nevertheless cognitive deficits may also be a risk factor for the development of drug and alcohol dependence. Numerous studies have investigated the effects of alcohol consumption on cognitive processes.
