Strehlow et al. describe the largest cohort to date of individuals with GRIN2A-related disorders. The results reveal two phenotypic subgroups associated with different classes of variants affecting distinct domains of the GluN2A protein with different functional consequences. The findings will help predict outcomes in newly diagnosed individuals.
Patients with schizophrenia showed deficits in hippocampal activation during a memory task relative to patients with bipolar disorder. The disorders were further distinguished by differences in PFC activation. The results demonstrate that these disorders can distinguished at a group level using non-invasive neuroimaging.
HIV/AIDS is associated with significant mental health morbidity in high-income countries, and depression associated with HIV/AIDS has been linked with faster disease progression and reduced drug adherence. However, research on mental health is scarce in sub-Saharan Africa where infection levels are highest. This cross-sectional study of 220 HIV-positive outpatients at a dedicated Tanzanian HIV/AIDS care centre assessed sociodemographics, clinical variables and prevalence of ICD-10 common mental health diagnoses via a standardised psychiatric questionnaire (the Clinical Interview Schedule-Revised). Depression or mixed anxiety and depression was identified in 15.5% of subjects, with 4.5% suffering from other anxiety disorders. This suggests routine HIV care in sub-Saharan Africa should include assessment and treatment of mental health issues.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
