Ashley offers specialist ADHD assessment for adults aged 18 years and over. The ADHD assessment process involves three key phases:

Intake and Screening - The first phase helps to determine if an ADHD assessment is clinically appropriate for you. It involves a 50-minute consultation and a number of brief questionnaires. In the consultation, you will discuss what challenges have brought you in for an assessment, as well as relevant background information such as your mental health history, family and social relationships, occupational and educational history, lifestyle factors, physical health, and more. - Detailed Assessment - The second phase involves the thorough assessment of your challenges in terms of the specific diagnostic criteria for ADHD. This includes symptoms of both inattention and hyperactivity/impulsivity, and considers these across the lifespan (childhood and adulthood). This phase usually involves two extended assessment sessions of 70-minutes each. School reports, previous cognitive assessments, or doctor’s referrals can be a useful input here. -           Results and Recommendations

  • Second Feedback Session
    The ADHD assessment process, and all the new information it entails, can be overwhelming. You are welcome to schedule a second feedback session to give you the opportunity to digest the information from the first feedback session, process your assessment report, and then return with any further questions you might have and discuss your recommendations for future support in greater detail. Significant others are welcome to attend this appointment with you if you would find it useful.

  • Additional Assessment Session
    In some cases, it may be necessary to conduct an additional assessment session. This is not common, but may be warranted in complex cases. You are also welcome to schedule an additional assessment session should you wish, for example if you would like a family member to provide face-to-face input into your assessment.
