Deaf people as a group experience a greater number of mental health problems than the general population (REF). Clinical diagnosis and intervention of deaf patients is particularly complex. This is due to the fact that deaf people very often use a different mode of communication i.e. sign language. In turn, deaf people's psychological and psychiatric intervention requires the establishment of special mental health unit with specialised professionals. These professionals must be highly qualified in alternative methods of communication and on issues relating to Deaf community and culture. The Gregorio Marañon Hospital in Madrid is one of the few mental health units for deaf people in Europe -that is, the Unidad de Salud Mental para Sordos (USMS). This unique service counts with a psychiatrists, a psychologist and a social worker. The aim of this presentation is twofold: to report to the scientific community the particularities of intervening with deaf population; and to highlight the need to adapt the diagnosis process and psychotherapy to this clients' needs. The poster presents descriptive data on deaf patients seen/treated at the USMS during 2007. Results will present patients' spread on the following variables: gender, age, referral, aetiology, age of deafness onset, preferred language, psychiatric diagnosis and treatment.
