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
