Does a change in provider ever require re-doing parts of the original assessment?

the answer is that sometimes, yes, parts of an ADHD assessment may need to be repeated when a different clinician becomes involved. Assessing ADHD and prescribing medication can involve different skill sets. While the original assessment provides the foundation for diagnosis, the prescribing clinician may need to explore certain areas in more detail to better understand the nuances of a person's symptoms before deciding which medication is likely to be the most appropriate. This isn't about questioning the original assessment—it's about ensuring that treatment decisions are based on the clearest and most up-to-date picture of your needs. It's also important to remember that people's presentations can change over time. Once ADHD symptoms begin to improve with medication, other aspects of someone's mental health or neurodevelopment may become more apparent. For example, features of autism spectrum disorder (ASD) or changes in mood symptoms may emerge more clearly once ADHD is being effectively managed. For this reason, if there is any uncertainty, it is often good clinical practice to revisit and review symptoms rather than relying solely on information gathered months or even years earlier. In my own practice, I also like to repeat parts of the assessment after someone has been taking medication for a while. This helps us understand what has changed. Have ADHD symptoms reduced? Which symptoms have improved the most? Are there any areas that remain difficult? Reviewing this together allows me to demonstrate the benefits of treatment, reflect on the progress that has been made, and identify areas where additional strategies or support may be helpful alongside medication.
