Recent results imply that rare variants contribute to the risk of schizophrenia. We conducted whole genome sequencing for 99 subjects from 20 Chinese families (parents and at least two siblings with a schizophrenia diagnosis and one unaffected sibling). Of the 9 frameshift mutations identified in more than 2 families, one was at chromosome 10:125780762 on the Carbohydrate Sulfotransferase 15 (CHST15) gene and another at chromosome 18:24722723 on the Carbohydrate Sulfotransferase 9 (CHST9) gene. We observed these deletions in 4 affected persons of two families from whole. At least two types of mutations (one or three bases insertion) have been identified …

We employed multi-electrode array recording to evaluate the influence of NMDA receptors (NMDAR) on spike-timing dynamics in prefrontal networks of monkeys as they performed a cognitive control task measuring specific deficits in schizophrenia. Systemic, periodic administration of an NMDAR antagonist (phencyclidine) reduced the prevalence and strength of synchronous (0-lag) spike correlation in simultaneously recorded neuron pairs. We employed transfer entropy analysis to measure effective connectivity between prefrontal neurons at lags consistent with monosynaptic interactions and found that effective connectivity was persistently reduced following exposure to the NMDAR antagonist. These results suggest that a disruption of spike timing and effective connectivity …

Early Diagnosis And Nutritional Treatment Stabilizes Neuropsychiatric Disorders, Ian James Martins
Research outputs 2014 to 2021
The reliable diagnostic identification of neuropsychiatric disorders such as schizophrenia, bipolar disease, and depression has been associated with some biological markers (genomics, proteomics, metabolomics) but to date, these markers do not have the sensitivity/specificity of a diagnostic test. Biomarker tests that are relevant to global chronic disease are now applicable to neuropsychiatric diseases to prevent autoimmune disease, endoplasmic reticulum stress associated mitophagy with relevance to neuron apoptosis. Metabolic abnormalities has been linked to neuropsychiatric disorder with the careful nutritional assessment of patients reported in many published studies. Early interventions with genomic medicine now assist in the prevention of autoimmune disease …

The study determined the prevalence ofMetS in patients with schizophrenia at the Psychiatric Unit of the Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana. This comparative cross-sectional study recruited 348 schizophrenic patients comprising 236 antipsychotic-treated and 112 newly diagnosed treatment-na¨ıve patients. The MetS prevalence was assessed based on World Health Organization (WHO), International Diabetes Federation (IDF), and the National Cholesterol Education Programme, Adult Treatment Panel III (NCEP ATP III) criteria. The overall prevalence of MetS was 14.1%, 20.4%, and 23.6% using NCEP ATP III, WHO, and IDF criteria, respectively, compared to 7.8%, 3.9%, and 2.2% reported in the generalGhanaian population.The prevalence …
