Areas of Clinical Interest
Daniel Mamah, MD’s clinical expertise focuses on the early identification and treatment of psychotic disorders, including schizophrenia and schizoaffective disorder. He is committed to advancing early intervention through a coordinated specialty care model, aimed at improving outcomes for adolescents and young adults experiencing early psychosis and those at clinical high risk. His research centers on the neurobiological mechanisms underlying psychosis, with a particular emphasis on the use of neuroimaging to identify biomarkers for early detection and treatment stratification. Dr. Mamah’s work aims to bridge the gap between cutting-edge neuroscience and practical clinical care, enhancing personalized treatment approaches for psychiatric disorders.
Research Interests
Dr. Mamah’s research combines advanced neuroimaging techniques and longitudinal studies to identify biomarkers that can predict the onset and progression of schizophrenia and other serious mental illnesses. He is particularly interested in understanding how structural and functional brain network changes relate to early psychosis, and how these changes can be leveraged for early diagnosis and personalized treatment. His work also explores the genetic and environmental factors contributing to psychiatric risk, aiming to improve both the early detection and treatment of individuals at risk for mental health disorders. In addition to his work in the U.S., Dr. Mamah has conducted epidemiologic, longitudinal, and neuroimaging studies in Kenya, where he has investigated the prevalence and progression of psychiatric disorders in African populations. Through his studies, Dr. Mamah seeks to enhance the precision and effectiveness of interventions for individuals experiencing early psychosis worldwide.
