In a previous study, we examined the frontal function by the Frontal Assessment Battery (FAB) and mental state through the Mini-Mental State Examination (MMSE) in 170 patients with alcoholism classified according to Lesch's typology (Zago-Gomes and Nakamura- Palacios 2009). In a global analysis, the alcoholics showed total scores on MMSE and FAB significantly smaller compared to non-alcoholics subjects. Type IV alcoholics showed lower scores on MMSE and FAB in comparison with non-alcoholics and all other types (Lesch's types I, II and III) of alcoholics. In a more specific analysis, even in alcoholics Type IV who had mental function (MMSE) preserved, the executive function (FAB) was significantly reduced (Zago-Gomes and Nakamura-Palacios 2009).
