Background One of the major consequences of substance misuse is its effect on patient cognition. Pregabalin is a new-generation antiepileptic which is believed to have an addictive effect. Objective This cross-sectional study is aimed to estimate the prevalence of cognition impairment among patients with pregabalin misuse. This study includes 300 patients and 100 controls with matched age, sex, and education. The drug abuse patients were divided into two groups: the first group patients used pregabalin alone and the second was a polysubstance group; each group was formed of 150 patients matched in sex, age, and educational level to the pregabalin group. For the diagnosis we used urine screening for drugs. We used the Montreal cognitive assessment test in Arabic edition to evaluate the cognitive function of the patient. Result Cognitive impairment was more in pregabalin misuse patients (M=25.4, SD=3.3) than in the control group (M=27.5, SD=3.7) according to the Montreal cognitive assessment test, P value less than 0.001. The most affected domains were visuoconstruction, digit span, verbal fluency, and recall, with dose (M=625, SD=400). There was no association between cognitive impairment and dose of pregabalin or duration of substance abuse. Conclusion This study concluded that pregabalin misuse patients were likely to have cognitive impairment due to the drug effect and their cognitive impairment was less than the polysubstance misuse group.
