OBJECTIVE: Previous reports suggest that cytokines act as potential mediators of the interaction between immune and neuroendocrine systems, a proinflammatory state may be associated with bipolar disorder schizophrenia. The aim is to compare cytokine levels in both disorders. METHOD: Twenty euthymic patients, 53 chronic stabilized schizophrenia patients 80 healthy controls were recruited. Subjects all non-smokers non-obese. Cytokines TNF-α, IL-6, IL-10 examined by sandwich ELISA. RESULTS:...

Schizophrenia has been defined as a neurodevelopmental disease that causes changes in the process of thoughts, perceptions, and emotions, usually leading to mental deterioration affective blunting. Studies have shown altered cell respiration oxidative stress response schizophrenia; however, most knowledge acquired from postmortem brain analyses or nonneural cells. Here we describe neural cells, derived induced pluripotent stem cells generated skin fibroblasts schizophrenic patient, presented...

Background Course and predictors of persistence attention deficit hyperactivity disorder (ADHD) in adults are still largely unknown. Neurobiological clinical differences between child adult ADHD raise the need for follow-up studies patients diagnosed during adulthood. This study investigates possibility full remission 7 years after baseline assessment. Method A 7-year with ( n = 344, mean age 34.1 years, 49.9% males) was conducted. Variables from different domains (social demographics,...

Article Abstract Background: Glutamate deregulation may be involved in the neuropathology of schizophrenia, mainly through N-methyl-d-aspartate (NMDA) receptor dysfunction. Memantine, a drug approved by FDA for treatment moderate to severe Alzheimer's disease, acts as weak nonselective NMDA antagonist. The aim this study was examine efficacy memantine an adjunctive clozapine patients with refractory schizophrenia. Method: In double-blind, placebo-controlled study, outpatients schizophrenia...

Abstract Since approximately 70% of adult patients with attention-deficit/hyperactivity disorder (ADHD) have at least one comorbid disorder, rating impairment specifically attributable to ADHD is a hard task. Despite the evidence linking environmental adversities negative outcomes in ADHD, life events measures not been used rate impairment. The present study tested for first time hypothesis that increased severity associated an increase recent events, independently comorbidity status....

Brain-derived neurotrophic factor (BDNF) plays a critical role in neurodevelopment and neuroplasticity. Altered BDNF signaling is thought to contribute the pathogenesis of schizophrenia (SZ) especially relation cognitive deficits. Clozapine (CLZ) has been shown beneficial effect on cognition SZ some studies detrimental others. To examine serum BDNF, two groups chronically medicated DSM-IV patients (n=44), treatment with clozapine (n=31) typical antipsychotics (n=13) had 5ml blood samples...

Background: Patients with schizophrenia (SZ) are generally overweight or obese and have several metabolic disorders. Additionally, such patients a lower life expectancy the main cause of their increased mortality is cardiovascular disease (CVD). The objective this study was to determine efficacy resveratrol supplementation on serum glucose CVD risk factors in individuals SZ. Methods Results: This four-week randomized, double-blind controlled trial (registration No.: NCT 02062190) which 19...

Schizophrenia is a neurodevelopmental disorder with genetic and environmental factors contributing to its pathogenesis, although the mechanism unknown due difficulties in accessing diseased tissue during human neurodevelopment. The aim of this study was find neuronal differentiation genes disrupted schizophrenia evaluate those post-mortem brain tissues from cases controls. We analyzed differentially expressed (DEG), copy number variation (CNV) differential methylation induced pluripotent...
