Apathy, cognitive deficits and functional impairment in schizophrenia
The findings confirm that apathy has a stronger relationship to functional impairment than cognitive deficits on a cross-sectional basis in schizophrenia, and suggest that apathetic and executive dysfunction might represent different manifestations of the same syndrome, probably sharing a common neural substrate.

Delusionality of body image beliefs in eating disorders
Body image delusionality in anorexia nervosa was associated with restrictive eating pathology, early onset of the disorder and body dissatisfaction, whereas in the bulimia group it was linked to shorter duration of the illness, more intense dieting behaviors and specific psychological factors: ineffectiveness and maturity fears.

Neurochemical variables in schizophrenic patients during switching from neuroleptics to clozapine
1. The study aimed to search for the effect of clozapine on the levels of the main metabolites of dopamine homovanillic acid (HVA), serotonin 5-hydroxyindoleacetic acid (5-HIAA) and norepinephrineExpand
The relationship between insight and theory of mind in schizophrenia
The findings confirm that ToM deficits negatively affect insight independently of co-existent neurocognitive deficits and symptom severity in chronic schizophrenia. Expand
Contrasting patterns of deficits in visuospatial memory and executive function in patients with major depression with and without ECT referral
A double dissociation emerged from the comparison of cognitive profiles of ECT and NECT patients, whereby ECT showed executive deficits, particularly in attentional flexibility, but mild deficits in tests of visuospatial memory, while NECTs presented the opposite pattern. Expand
Clinical characteristics of auditory hallucinations
This finding supports the hypothesis that the concept of auditory hallucinations represents many aspects of patients’ hallucinatory experiences, which are relatively independent of one another. Expand
Psychotic (delusional) major depression in the elderly and suicidal behaviour.
The notion that psychotic features do not increase the risk for the elderly depressed patients to attempt suicide is supported. Expand
A magnetic resonance imaging study of hippocampal, amygdala and subgenual prefrontal cortex volumes in major depression subtypes: melancholic versus psychotic depression.
Regression analysis revealed that AVs were predicted by the presence of depression, late depression-onset, insomnia and left hippocampal tail volume in patients, but not in controls, and significant volumetric differences were detected between both patient-groups and controls. Expand
The relationship of Theory of Mind with symptoms and cognitive impairment in bipolar disorder: a prospective study.
The hypothesis that ToM dysfunction in BD is associated with mood symptoms and it might reflect underlying cognitive deficits rather than representing a specific trait marker of the disorder is supported. Expand
Mental pain and suicide risk: application of the Greek version of the Mental Pain and the Tolerance of Mental Pain scale.
The findings offer support to the hypothesis that mental pain is a clinical entity distinct from depression with a specific and important contribution to the suicide risk. Expand
