Memantine is an FDA-approved, non-competitive NMDA-receptor antagonist that has been shown to have mitochondrial protective effects, improve cell viability and enhance clearance of Aβ peptide. Currently, there are uncertainties regarding the precise molecular targets as well as the most favourable treatment concentrations of memantine. Here, we made use of an imaging-based approach to investigate the concentration-dependent effects of memantine on mitochondrial fission and fusion dynamics, autophagy and mitochondrial quality control using a neuronal model of CCCP-induced mitochondrial injury so as to better unpack how memantine aids in promoting neuronal health.

One of the biggest threats to early childhood development in Africa is poor maternal mental health. The present study reports on the relationships between clinical diagnoses of persistent maternal mental health disorders (at 3- and/or 6- and 18-month post-term age) and toddler neurodevelopment at 18 months of age. Eighty-three mother-toddler dyads from low socio-economic status settings in Cape Town, South Africa, were included.

Background: Deinstitutionalisation refers to the process of transferring most of the psychiatric care provision from inpatient state-run institutions to community-based care. However, it has proven difficult to implement and failed to reach its desired targets. New Beginnings (NB) is a transitional care facility that facilitates the transition from in- to outpatient care.

Maternal mental health disorders and the adverse consequences for infant neurodevelopment have received substantial research attention in high-income countries over the past five decades. In Africa, where relatively little work has been done on this topic, researchers have largely focused on infant physical health outcomes. This longitudinal study investigated the neurodevelopment of infants at 6 months post-term with exposure to mothers with a clinical diagnosis of persistent mental health disorders residing in low-income communities in Cape Town, South Africa.
