ADHD and autism are separate neurodevelopmental conditions that require different assessment processes, though they frequently co-occur. An ADHD assessment focuses on attention, concentration, impulsivity, hyperactivity, and executive function, using tools such as the Conners rating scales and a structured clinical interview. An autism assessment is more comprehensive — at Harley Mind Care it includes the ADOS-2 (Autism Diagnostic Observation Schedule), a face-to-face structured observation conducted by a psychologist or appropriately skilled clinician, alongside clinical interview and developmental history. Because ADHD and autism overlap significantly, many patients benefit from a combined assessment. Please speak to our team about whether a combined or separate assessment is most appropriate for your situation.
