Background: Many intracranial lesions can induce psychotic symptoms. Arachonoid cyst is one of the suspicious etiologies. A possible link between arachnoid cyst and psychosis gives an interest to the pathogenesis of psychotic symptoms. Here, we present a case of schizophrenia with a large cerebellar arachnoid cyst. Case Presentation: Ms. Lu is a 31-year-old woman with schizophrenia for 7 years...

UNLABELLED The relevance of negative symptoms across the diagnostic spectrum of the psychoses remains uncertain. The purpose of this study was to report on prevalence of item and subscale level negative symptoms across the first episode psychosis (FEP) diagnostic spectrum in an epidemiological sample, and to ascertain whether items and subscales were more prevalent in a schizophrenia spectrum d...

Tissue plasminogen activator (tPA) mediates a number of processes that are pivotal for synaptogenesis and remodeling of synapses, including proteolysis of the brain extracellular matrix, degradation of adhesion molecules, activation of neurotrophins, and activation of the N-methyl-d-aspartate receptor. Abnormalities in these processes have been consistently described in psychotic disorders. In ...

Psychotic symptoms and disorders can emerge due to structural brain abnormalities. The septum pellucidum is one of the midline brain structures, which consists of the fusion of two thin membranes. Cavum vergae is recognized as the most severe form of fusion defect in the membranes of septum pellucidum. Although cavum vergea is reported to be common in schizophrenia and other psychotic disorders...

Chromosome 18 abnormalities are associated with a range of physical abnormalities such as short stature and hearing impairments. Psychiatric manifestations have also been observed. This study focuses on the presentations of psychiatric syndromes as they relate to specific chromosomal abnormalities of chromosome 18. Twenty-five subjects (13 with an 18q deletion, 9 with 18p tetrasomy, and 3 with ...

The Defense Mechanisms Rating Scales (DMRS), one of the most widely used and validated instruments in the study of defense mechanisms, does not include psychotic defenses. The Psychotic-DMRS (P-DMRS) has been developed to include 6 psychotic defense mechanisms: psychotic denial, autistic withdrawal, distortion, delusional projection, fragmentation, and concretization. We discuss psychotic defen...

BACKGROUND Conflicting evidence exists about the relationship between psychotic symptoms and suicidality in mood disorders. We aimed to investigate the lifetime suicidality and its relationship with dimensions of the psychotic spectrum over the lifespan among subjects with bipolar I (BD I) or major depressive disorder (MDD). METHODS 147 Consecutive out- and inpatients with BD I or MDD present...

Amphetamine abuse may lead to a psychotic state, its symptomatology being very similar to what is seen in paranoid schizophrenia. Failure of attentional inhibition of irrelevant information is thought to be associated with the psychotic symptoms in schizophrenia. Negative priming (NP) paradigm is believed to measure this impairment. Several studies have shown impaired NP in schizophrenia. In th...
