Alcohol in beverage form is among the most widely used psychoactive drugs in the world and it has dependence producing properties. Ethanol in alcohol is a chemical and after consumption has a multitude of effects.

Aims and objective: The aim of this study was to assess the cognitive functions in patients with alcohol dependence as compared to the normal controls by using Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA).

Materials and methods: This study included 44 patients with alcohol dependence diagnosed as per international classification of disease tenth edition criteria with a mean age of 43.61 ± 7.38. Cognition was tested using a sensitive battery of psychometric testing Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA).

Results: Compared with healthy subjects (n=44), patients had lower total scores of cognitive testing (MMSE) (P=0.010) and Montreal Cognitive Assessment (MoCA) (P=0.000).

Conclusion: Our results indicated cognitive impairment in patients with alcohol dependence. This is important to determine prognosis and managing patients.
