Does Memantine Improve Social Functioning in Autism?

View the mentioned paper here:Memantine to Treat Social Impairment in Youths With Autism Spectrum Disorderhttps://jamanetwork.com/journals/jamanetworkopen/fullarticle/2839518 Access the mentioned course here:Understanding Autism Spectrum Disorder: A Comprehensive Guide to Clinical Assessment & Diagnosishttps://psychscene.co/4zXOHNW In this video, Dr Sanil Rege examines a 2025 randomised controlled trial of memantine for social impairment in young people with Autism Spectrum Disorder (ASD). He explores whether memantine can improve social functioning and outlines how glutamatergic dysregulation, NMDA receptor modulation, and elevated anterior cingulate glutamate may help identify a biologically responsive subtype. He also considers how this may move the field beyond viewing autism as a single, uniform condition. This session provides clinicians with a neurobiological framework for understanding autism through biomarkers, circuit dysfunction, and emerging precision psychiatry principles.  Chapters:- Memantine for Social Impairment in Autism- Why Autism May Not Be One Uniform Condition- Trial Design and Participant Profile- pGACC Glutamate as a Biomarker- Response Rates and Subgroup Findings- NMDA Receptors and Glutamatergic Mechanisms- Memantine Versus Ketamine- From Autism Spectrum to Neurobiological Subtypes #Autism #Memantine #Psychiatry

Access mentioned course here: https://psychscene.co/46iAaiIIn this episode, Consultant Psychiatrist, Dr Sanil Rege examines the complex relationship between ADHD pharmacotherapy and the emergence of psychotic symptoms.By analysing synthesis data from The Lancet Psychiatry (https://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366(25)00248-2/abstract), the podcast distinguishes between drug-induced events and baseline neurobiological vulnerabilities inherent in ADHD populations.This podcast provides clinicians with a neuroscientific framework for differentiating between protopathic bias and true medication-induced psychotic phenomena, as well as a step-wise screening pathway for risk-guided prescribing using validated at-risk mental state (ARMS) triage tools.To get access to the complete podcast catalog and material like this plus over 150 hours of interactive CPD education on psychiatry, check out The Academy using the link below:https://psychscene.co/45M67jh

The authors also propose a unifying “catecholamine hypothesis” explaining sleep’s restorative functions across brain, immune, and metabolic systems.We break down what this means for clinicians, how it updates classic models of sleep–wake regulation, and why dysfunction in these systems manifests across psychiatry.To access all episodes of this podcast plus 150+ hours of advanced psychiatric education, join the Academy today.
