[The creation of a new pathology in Paris. The case of deinstitutionalized patients]

The development of attitudes towards the mentally ill, the progress of psychotherapeutic care and medicines, allowed the looking after of psychotic patients outside of the hospital institution, while keeping their social links with their personal environment. The setting up of alternative structures in the context of the communitary psychiatry was supposed to enable the reinsertion of the stabilized psychotic patients. In Paris, the lack of such structures, and the difficult socio-economic context condemn these patients to drifting aimlessly, locked out of any institution, which worsen their pathological state. These "deinstitutionalized" patients cause a serious problem for the Health system.
