With the goal to study peculiarities of functional asymmetry of the brain hemispheres in alcohol dependence, there has been done an analysis of current research data from Russian and foreign studies. It has been shown that alcohol is a neurochemical modulator of interhemispheric relations, it affects functional asymmetry of the brain hemispheres, perception processes, changes emotional background, influences motor asymmetry, the brain cortex functional activity. Alcohol intoxication is described by the right hemisphere lateralization and a laterodeviation of the brain hemispheres’ functional asymmetry to the left hemisphere. Studies of adolescents with beer alcoholization have shown left sided laterodeviation of functional asymmetry with dominating left-sided lateralization of motor signs, increased delta activity of the brain biorhythms. The received data indicate a substantial breach of functional asymmetry in alcohol users, in what connection the breach involve the motor and sensory levels.
