Alcohol abuse and alcohol dependence produce very high health costs. Nowadays, early detection and intervention are very well accepted. Due to the well proven theory regarding the heterogeneity of al- cohol dependence and for the purpose of research and therapy, four subgroups of alcohol dependence have been established. Methods. The Lesch Typology was developed as a result of a prospective long - term study and led to a decision tree identifying alcohol dependent patients’ subgroups. The results show that each subgroup re- quires different and specific treatments. Within the framework of a computer programme (www.LAT-on- line.at) the decision tree can be used very easily. Meanwhile, this method has been field – tested in nu- merous basic and clinical trials. After the diagnostic procedure, a protocol of the questionnaire displays reachable and realistic treatment goals. Furthermore, it provides information about the guidance and treat- ment of each patient subgroup. Conclusion. Nowadays, the heterogeneity of the disease alcohol dependence is without any doubt an ac- cepted certainty. By utilizing the Lesch Typology, specific treatment approaches of the diverse subgroups may be applied accordingly. Discussion. Using the subgroups defined in the Lesch Typology for basic and clinical research subgroup customized treatments can be prescribed, and consequently even better treatment outcomes in alcohol dependent patients can be awaited. alcohol dependence/ Lesch typology/ subtypes/ withdrawal and relapse prevention treatment INTRODUCTION treatment is mainly used for alcohol withdraw- al and for relapse prevention.
