Abstract
It is well established that we have to consider 3 patterns of psychotic symptoms: positive (hallucinations, delusion...), negative (affective flatness, autism...) symptoms and disorganization (ambivalence, incoherence...). In the past, ECT (electroconvulsivotherapy) was the first effective treatment in psychiatry. Conventionnal neuroleptics have been determinant in the significant evolution of care to psychotic patients. ECT use is now better defined in terms of practise and indications. Assessment of new antipsychotic medications is mainly focused on efficacy on positive symptoms. Atypical antipsychotics brought improvement in treating psychotic syndromes: they are better tolerated and more effective on the whole spectrum of psychotic syndromes including emotional symptoms than conventional neuroleptics. Atypical antipsychotics have raised questions about metabolic and cardiac risks. Compliance remains a cause of failure of many antipsychotic treatments. Treating a psychotic syndrome requires complementary strategies to medications: conditions of assistance and rehabilitation, choice of psychotherapy. Research program are currently orientated towards: - identification of prepsychotic symptoms and endophenotypes which can be treatment targets; - assessment of putative therapeutical means such a brain stimulation.
