[The course of restitution of learning and concentrating ability in chronic alcoholics in the 1st year of abstinence].

Aim of our investigation was the analysis of the performances of chronic alcoholics under abstinence. 3 groups of 30 alcoholics were investigated after 3 weeks, 3 months and one year and compared with a group of control (n = 30). The most essential results: Strong increase in the first 3 month, after only slow increase. The level of healthy population has been attained nearly but not complete. The restitution is independent of the age and sex but significant dependent to the type of drinking (gamma- and deltadrinker). This results are important for the occupational rehabilitation of alcoholics after therapy.
