Dr Achuthan obtained his MBBS in Malaysia and completed his consultancy training in General Adult Psychiatry in the United Kingdom.

He is trained in ADOS-2 and ADI-R and has extensive experience delivering ASD and ADHD assessments, including complex and overlapping presentations and co-existing mental health needs. His approach is formulation-led and aims to help individuals and families understand not only diagnostic conclusions, but also the wider context that can shape symptoms, coping and functioning over time.
He is also an author, with three books now published and a fourth currently in progress (What is Trauma?).
