[Research in psychiatry].

The department of psychiatry of the Université de Montréal has now organized a well structured research network in the area of child, adult and forensic psychiatry. The authors summarize the scientific approach according to research in these different sectors and believe that, although research in psychiatry now tends to promote diagnostic and treatment methods based more and more on neuro-sciences, it does not neglect the contribution of psychosocial and clinical aspects without which the human dimensions of mental illness and the objective of improvement of care to patients would be rapidly forgotten on behalf of disembodied research projects completely deprived of the relation with patients.
