About

Arjen Maatkamp is a pioneering researcher whose work bridges the fields of neuroimmunology and developmental psychiatry, with a particular focus on autoimmune mechanisms underlying neuropsychiatric disorders. His most influential contribution, the 2011 paper "Late onset autism and anti-NMDA-receptor encephalitis" (76 citations), established a critical link between anti-NMDA-receptor encephalitis—an autoimmune condition—and the emergence of autism spectrum symptoms in later childhood and adolescence. This groundbreaking study challenged conventional views of autism as purely neurodevelopmental, proposing instead that some cases may stem from treatable immune-mediated processes. Maatkamp’s work has significantly impacted clinical practice, encouraging routine screening for autoimmune encephalitis in patients with atypical or regressive autism. His research has been widely cited in neurology, psychiatry, and immunology, underscoring its interdisciplinary relevance. By illuminating the intersection of autoimmunity and neurodevelopment, Maatkamp has opened new avenues for targeted therapies, offering hope for improved outcomes in patients with immune-related autism. His contributions continue to inspire further investigation into the role of the immune system in neuropsychiatric conditions.
