Schizophrenia* The schizophrenic syndrome usually begins between late adolescence and early adulthood

* Three syndromes cardinals dissociation, autism, paranoid delusions.

* Dissociative syndrome: is not pathognomonic of schizophrenia; It is the loss of cohesion and unity of personality

* Morbid Rationalism: incoherent explanation of actual concrete events

* Catatonia: psychomotor attitude essentially of inertia and negativity; mutism, stupor sometimes hyperkinesia (sudden motor impulse)

* Paranoid delirium: delirium poorly structured, fuzzy, not systematized, sometimes devoid of particular thematic or changing thematic focus. The most common themes are depersonalization, often printing accompanied by physical changes or body dysmorphic disorder; delusions of persecution, influence, parentage ….

mental automatism (flight of thought imposed thoughts echoes of thought, influence syndrome)

* Positive Symptoms: delusions; hallucinations; disorders of formal thought (illogicality, inconsistency, diffluence, tangentiality); bizarre or disorganized behavior (eccentric; stereotyped; aggressive …).

* Negative symptoms: poverty of speech; flat affect; amimie; anhedonia and social withdrawal; apathy and alteration of the will; attention deficit disorder; listlessness.

* Deficit table (dementia) is gradually in a few years; it is particularly to be feared in the hebephrenia. The demonstrations are the predominant affective flattening, the listlessness and disorganization.

* Stabilization: the most frequent progressive profile (50%) especially in case of paranoid schizophrenia and Schizoaffective

* The complete or almost complete remission is possible (25% of cases)

* Schizophrenia resistant to neuroleptics -> interest of clozapine: Leponex®
