Private ADHD Assessment for Adults

Until recently, people believed that ADHD only affected children, meaning many adults missed out on seeking an ADHD diagnosis. As awareness continues to grow, so does the demand for accurate ADHD assessments.

If you believe you have ADHD, a Private ADHD Assessment for Adults can provide a much-needed light at the end of the tunnel.

The Importance of Identifying Adult ADHD

ADHD is a neurodevelopmental disorder that affects both children and adults. However, due to misconceptions and lack of awareness in the past, many adults grew up without a proper ADHD diagnosis, leading to struggles in their professional and personal lives. Seeking a private ADHD assessment as an adult can provide clarity and access to the necessary support and treatment.

Diagnostic Interview and Evaluation

During the ADHD assessment, our clinician will conduct a diagnostic interview, exploring your developmental history, behaviour patterns, and any associated issues such as anxiety and depression. You will have the opportunity to discuss your current experiences and concerns in detail.

Final Diagnosis and Recommendations

Experts in Diagnosing and Treating ADHD

An ADHD assessment consists of a diagnostic interview with the patient and a family member or someone who knows the patient well to identify potential ADHD symptoms and impairments. The assessment will look at your experiences from childhood and how your symptoms impact your day to day life now. The assessment is conducted using a diagnostic tool called DIVA (Diagnostic Interview for ADHD in Adults), which is a structured interview based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). 


During the assessment the clinician will determine the extent to which the symptoms from DSM 5 currently apply to the adult and if they have been present in childhood. Symptoms can change over time, so adults may present differently from when they were children. A diagnosis is based on the number and severity of symptoms, the duration of symptoms and the degree to which the symptoms cause ‘functional impairment’ in the different areas of life, such as home, work, and social life.

    An ADHD assessment is usually carried out after a child's 6th birthday, the reason for this is due to a complicated process which the brain carries out called 'synpatic pruning'. This determines how well the brain is being wired and which parts of the brain are being pruned due to cell death and decay. This process begins to slow down and stabilise in early childhood, after the age of 6. Therefore assessing a child after the 6th birthday is a relaible indicator of how well this process has taken place and the impact of inefficient synaptic pruning.
