CNWL Adult ADHD Assessment and Treatment Service

About the service

The CNWL Attention Deficit Hyperactivity Disorder (ADHD) clinic offers diagnosis and medication stabilisation for adults with ADHD, in preparation for discharge back to their GP for continued prescribing and monitoring.

We do not offer psychological interventions for the treatment of ADHD in our clinic.

Who is this service for?

CNWL ADHD service is aimed at:

  • Men and women over 18 years old and
  • Those who already have an Adult ADHD diagnosis or
  • Adults previously diagnosed with ADHD in childhood and with symptoms suggestive of continuing ADHD or
  • People suspected of having ADHD in adulthood with supporting evidence such as onset in childhood as well as details of current symptoms and impairment
  • Those dependent on illicit drugs or alcohol will need to undergo appropriate treatment before they can be accepted. The presence of active drug or alcohol problems is not necessarily an exclusion criterion but will be reviewed critically by the service in deciding whether or not to assess the service user, and a discussion with the referrer will take place to inform the decision.

Before referral

Before we can accept a referral and assess a patient, they need to have funding authorised on a case-by-case basis by their local Clinical Commissioning Group (CCG), our administration team will arrange for this.

The funding authorised will be for:

  • One initial assessment
  • Up to three follow up assessments
  • One follow up appointment within six months of discharge
