Resumen Objetivos El estudio de la concentración de N-acetil-aspartato (NAA) proporciona datos interesantes sobre las alteraciones corticales en las enfermedades psicóticas. Aunque la reducción de la concentración de NAA en la corteza cerebral es un resultado habitual en la esquizofrenia crónica, es menos constante en la enfermedad bipolar. Por ot...
Article
Schizophrenia is a heterogeneous clinical condition that may reflect a variety of biological processes. In particular, treatment-resistant (TR) schizophrenia may have a distinct neurobiological substrate. Within the context of clinical data, a simultaneous study with different imaging techniques could help to elucidate differences in cerebral subst...
Article
A study of N-acetyl-aspartate (NAA) can provide data of interest about cortical alterations in psychotic illnesses. Although a decreased NAA level in the cerebral cortex is a replicated finding in chronic schizophrenia, the data are less consistent for bipolar disease. On the other hand, it is likely that NAA values in schizophrenia may differ in m...
Article
Full-text available
Previous data show that the effects of clozapine on regional brain activity are different from those of other antipsychotic agents. It seemed of interest to study the brain activity patterns after treatment with clozapine, since this drug might correct basal deficits directly related to schizophrenia or instead induce changes that would in some way...

Full-text available
Regions with a likely involvement in schizophrenia may differ between patients with first-episodes of psychosis respectively with and without evolution into schizophrenia following the initial episode. We have used magnetic resonance imaging (MRI) to assess the volumes of dorsolateral prefrontal (DLPF) and superior temporal gyrus (STG) in a group o...
Article
Full-text available
The cellular substrates of cortical volume deficit in schizophrenia are unclear. We may hypothesize that, if that deficit was related to a decrease in the amount in neuronal tissue, it should correlate with N-acetyl aspartate levels. We studied a group of 34 schizophrenia patients (of them, 17 first episodes) with both structural and spectroscopic...
Article
The effects of atypical antipsychotic treatment on the brain volume deficits associated with schizophrenia are poorly understood. We assessed the brain volumes of eleven healthy controls and 29 patients with schizophrenia, using magnetic resonance imaging at baseline and at follow-up after two years of treatment with atypical neuroleptics. Two grou...

Resumen Objetivo Se ha reconocido una cantidad mayor de líquido cefalorraquídeo (LCR) cortical como un posible marcador de una pérdida de sustancia gris. Esta cantidad mayor en la esquizofrenia se encuentra predominantemente en las regiones prefrontal y temporal. Planteamos la hipótesis de que la evolución global y la respuesta al tratamiento peor...
Article
Abnormalities of the P300 component of the event-related potential are a common finding in schizophrenia. It seems possible that the dysfunction in the dorsolateral prefrontal (DLPF) region that has been reported in schizophrenia contributes to this finding. To explore this possibility, we calculated the relationship between, on the one hand, P300...
Article
Excessive cortical cerebrospinal fluid (CSF) has been acknowledged as a possible marker of a gray matter loss. This excess in schizophrenia is found predominantly in the prefrontal and temporal regions. We hypothesized that the poorer global outcome and treatment response in males with schizophrenia are related to a greater cortical volume loss as...

Decreased metabolic activity in the prefrontal cortex during cognitive activation is a recurrent finding and a likely functional marker of schizophrenia. To investigate the occurrence of hypofrontality in patients with first-episode psychosis, with or without evolution to schizophrenia. We used fluorodeoxyglucose positron emission tomography during...
Article
Magnetic resonance spectroscopy studies in schizophrenia have revealed consistently reduced N-acetyl aspartate (NAA) levels in chronic patients, but not in recent-onset patients. Studies on the relationship between this marker and disease duration have commonly been negative, although it is also true that they have been conducted in patients with l...
Article
Reduced volume and activity of the prefrontal (PF) cortical gray matter (GM) and hippocampal hypermetabolism are repeated findings in schizophrenia. There is still an information deficit about the significance of reduction of PF GM in schizophrenia, and a simultaneous study of PF anatomy and activity and limbic metabolism can contribute to fill tha...
Article
Although a lower volume of prefrontal (PF) gray matter (GM) in patients with schizophrenia than in normal control subjects is a replicated finding, it is not yet clear whether this finding is present at the onset of illness. Clinical and imaging data suggest that the reduction in PF GM becomes apparent only some years following the onset of illness...
Article
Clozapine alleviates the symptoms of a significant proportion of treatment-resistant schizophrenic patients. Previous studies suggest that the response to clozapine may be associated with prefrontal and temporal anatomy as well as with prefrontal, basal ganglia and thalamic metabolism. A sample of 25 treatment-resistant (TR) schizophrenic patients...
Article
In schizophrenia, structural and functional cerebral variables show an unclear association with clinical features and their value as predictors of response to a typical antipsychotic agents has yet to be determined. The goal of this study was to investigate the relationships between clinical variables (baseline syndromes and response to risperidone...

The interpretation of the huge number of results in schizophrenia research using neuroimaging is uncertain. However, the simultaneous use of complimentary data obtained with these techniques may yield more relevant information in this regard. In this paper, we present a series of studies performed by our group in two schizophrenic samples with the...
Article
The existence of neurodegeneration is a debated issue in schizophrenia research. The P300 component of event-related electrical potentials (ERP) has been related to the different degree of damage to gray and white matter. This study explores the possible relationship between P300 amplitude and/or latency and the existence of degenerative processes...
