Better treatments for schizophrenia are urgently needed. The therapeutic use of the nitric oxide (NO)-donor sodium nitroprusside (SNP) in patients with schizophrenia has shown promising results. The role of NO in schizophrenia is still unclear, and NO modulation is unexplored in ketamine (KET) animal models to date. In the present study, we compared the(More)
OBJECTIVE The last decade has seen increasing evidence of dysfunctions in the endogenous cannabinoid system in schizophrenia and of its relationship with the typical cognitive impairment of the disorder. Studies in animal models, healthy volunteers, and psychotic patients clearly suggest an antipsychotic-like effect of cannabidiol. This study investigated(More)
Despite the wide variety of currently available antipsychotics, their efficacy is limited only to the improvement in positive symptoms. In addition, longitudinal cohort studies of patients with first episode psychosis show worsening in different psychopathological domains and progressive loss of brain gray matter volumes. Beyond changes in neurotransmitter(More)
Growing consistent evidence indicates that hypofunction of N-methyl-D-aspartate (NMDA) transmission plays a pivotal role in the neuropathophysiology of schizophrenia. Hence, drugs which modulate NMDA neurotransmission are promising approaches to the treatment of schizophrenia. The aim of this article is to review clinical trials with novel compounds acting(More)
Increasing evidence suggests that the tetracycline antibiotic minocycline has neuroprotective effects and is a potential treatment for schizophrenia. However, the mechanisms of action of minocycline in the CNS remain elusive. The aim of this study was to investigate the effects of minocycline on brain morphology and cerebral perfusion in patients with(More)
OBJECTIVE Olanzapine is an atypical antipsychotic drug used to treat schizophrenia. Some of the adverse effects related to its use are obesity, hyperlipidemia, type 2 diabetes and hypertension, which may result in development of metabolic syndrome. This study aimed to investigate a possible increase in some anthropometric and biochemical parameters, and the(More)
BACKGROUND Neuropsychiatric sequelae are the predominant long-term disability after traumatic brain injury (TBI). This study reports a case of late-onset social anxiety disorder (SAD) following TBI. CASE REPORT A patient that was spontaneous and extroverted up to 18-years-old started to exhibit significant social anxiety symptoms. These symptoms became(More)
UNLABELLED Schizophrenia is a severe psychiatric disorder with a complex presentation comprising positive symptoms (e.g.: hallucinations and delusions), negative symptoms (e.g.: social withdrawal, blunted affect) and pervasive cognitive deficits that have been associated with functional decline. The pathophysiology of the disorder is equally complex, with(More)
