[Psychosis and epilepsy: clinical and therapeutical approach].

Psychosis in epilepsy has generated controversy among the community of psychiatrists and neurologists throughout history. Currently, several contemporary researchers have found an increased frequency of psychosis in epilepsy, and identified risk factors related to the severity of epilepsy.In this review, we describe the main epidemiological, clinical and therapeutic issues, implicated in epileptic psychosis.

[Negative symptoms in patients with non schizophrenic psychiatric disorders].

Introduction: The presence of negative symptoms (NS) in different clinical entities other than schizophrenia, with a dimensional approach of negative symptoms, was considered in this work.

Objectives: Determine the presence and distribution of NS, in a population of patients with non schizophrenic psychiatric disorders attending ambulatory treatment at public hospitals.

Methods: Patients with define DSM IV diagnosis criteria for different disorders; affective, alimentary, substance abuse, anxiety, personality disorders and patients with ILAE diagnoses criteria for temporal lobe epilepsy were included.

Psychotic disorders in Argentine patients with refractory temporal lobe epilepsy: a case-control study.

The issue of psychotic disorders in epilepsy has given rise to great controversy among professionals; however, there are not many studies in this area and the physiopathological mechanisms remain unknown. The aim of this study was to describe the spectrum of psychotic disorders in an Argentine population with refractory temporal lobe epilepsy (RTLE) and to determine the risk factors associated with psychotic disorders. Clinical variables of the epileptic syndrome were compared among a selected population with RTLE with and without psychotic disorders (DSM-IV/Ictal Classification of psychoses).

[The meaning of obsessive features of personality in the vulnerability and prognosis of schizophrenia].

In this study on schizophrenia, we raise the issue of the existing relation between negative symptoms (also called symptoms of deficiency) cognitive impairment attributed to the illness and personality features, in a population of chronically ill, long-term hospitalized men. We found obsessive personality features were present in the group of patients which presented fewer signs of deficiency and cognitive impairment. The presence of these features constitutes an important element in the evaluation of prognosis and vulnerability to suffer the illness.
