Adult Autism and ADHD Diagnostic Assessments

For many people, an assessment for autism and/or ADHD in adulthood can assist with self-understanding and be important in answering questions you may have about whether a diagnosis is relevant to you. It is common to have read about autism and ADHD and found many of the features resonate with your own experiences. Seeking a diagnosis can add clarity to this.

CATS provide adult assessments in Norfolk, Suffolk and North East Essex. Our clinicians have each been working with adults with autism and ADHD for over twenty years and have experience in approaching assessment from a strengths-based position. We also have specific training in assessing autism in women where autism can present differently.

We are able to offer ongoing mental health and therapeutic support.

We do not currently provide a prescribing service for adults.
