What is an ADHD assessment?
ADHD assessments typically involve a series of evaluations to determine if an individual meets the DSM criteria for Attention Deficit Hyperactivity Disorder. These assessments can include interviews with the individual, their parents or caregivers, and teachers to gather information about symptoms and behaviours. Additionally, questionnaires and rating scales may be used to assess the severity of symptoms and their impact on daily functioning. Other assessments, such as cognitive neuropsychology testing and behavioural observations, may also be carried out to provide a comprehensive understanding of the individual's difficulties. Overall, the assessment process for ADHD aims to accurately diagnose the condition and develop an appropriate treatment plan to help manage symptoms effectively.
What does an ADHD assessment for adults involve?
An ADHD assessment for adults typically involves thoroughly reviewing the individual's history, symptoms, and behaviour patterns. It may include self-report questionnaires, interviews with family members or significant others, and cognitive testing to assess areas such as attention, impulsivity, and hyperactivity. At TT Coaching we have over twenty years experience in making important SEN decisions.
How long is the assessment?
The booking process and initial questionnaire should only take a few minutes. The assessment itself involves a 60-minute discussion, followed by a comprehensive assessment report, which will be emailed within 10 working days.

What happens if I'm diagnosed with ADHD?
If you are diagnosed with ADHD, you will receive a proposed treatment plan along with options tailored to your diagnosis, as well as an information pack.
What about medication?
For adults with ADHD, treatment often includes stimulant medications such as Methylphenidate (Ritalin, Concerta) and Amphetamine-based drugs (Adderall, Vyvanse). These medications help improve focus, attention, and impulse control and are usually prescribed in higher doses compared to those for children. Non-stimulant options like Atomoxetine (Strattera) are also available, particularly for adults who have additional conditions like anxiety or heart issues.
ADHD titration involves starting with the lowest dose of ADHD medication and gradually increasing it. It may take up to a week to notice a difference in your symptoms when taking the medication.
It’s common to have a few side effects with ADHD medication, but titration is how we avoid this by gradually increasing the dose. Some side effects are reduced appetite, weight loss, transient blood pressure increases, headaches and trouble sleeping.
*After diagnosis with TT Coaching, clients will be able to explore medication options with the confidence that they have been professionally diagnosed under UK NICE guidelines.

ADHD Coach | Trevor Twohig
Trevor is a qualified counsellor and ADHD Assessor who has spent twenty years in senior leadership and education in Kent schools. Trevor worked in SEN and directly with ADHD/Autism before becoming a neurodiversity coach. He has often been commended on his ability to relate to young people with difficulties and it his own lived experience that makes him so profient in this area.
"As someone with ADHD, I am acutely aware of the problems and pitfalls it presents. I have struggled with low self-esteem, rejection sensitive dysphoria, a constant sense of underachievement, and the feeling that no matter how hard I try, my relationships will ultimately fail.
Having been diagnosed in later life and learned deeply about the condition, I have turned what was once a problem into a neurodivergent superpower. I have been happily married for ten years and have four beautiful children. I have great friends and have managed to transition into a career where I am helping others achieve their lifelong goals.
As someone previously on ADHD medication, I made the decision to cease taking it and found natural ways to remedy the adverse effects of the condition. I am not anti-medication, but can provide a balanced perspective on whether it is right for the individual in question.
When harnessed correctly, ADHD can be a brilliant tool that can drive you to an outstanding life. Through our sessions I can give you the support, resources and information to create the dream life you have always wanted. " - Trevor Twohig, 2025
