Due to its interdisciplinary research MHH has strong collaborative links with many academic and industrial research organizations worldwide. At the Clinic of Psychiatry, Socialpsychiatry and Psychotherapy, in 1994 a specialised outpatient department was established for the diagnosis and treatment of patients suffering from Tourette’s syndrome (TS) and other tic disorders. During the last years, more than 1.500 patients have been investigated at our centre. Today, it is the largest Tourette syndrome clinic in Germany. Several clinical trials in Tourette syndrome have been conducted during the last years, including national and international co-operations.
