An adult autism assessment at Harley Street Mental Health is a thorough, evidence-based evaluation designed to identify signs of Autism Spectrum Disorder (ASD) in adults. Our expert psychiatrists and psychologists use gold-standard tools such as the ADOS-2 and structured clinical interviews to explore developmental history, social communication patterns, sensory differences, and daily life experiences. We provide detailed diagnostic reports and clear guidance on post-diagnostic support, helping adults receive the understanding and care they deserve.
