ADHD Assessment FAQs

A few of our frequently asked questions about assessments

What is the assessment for ADHD?

FAQ arrow

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?

FAQ arrow

An ADHD assessment for adults typically involves thoroughly reviewing the individual's medical 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.

What happens if I'm diagnosed with ADHD?

FAQ arrow

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 outlining the next steps for implementing your treatment plan.

What if I decide to take medication?

FAQ arrow

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.

How much does ADHD medication cost?
FAQ arrow

Medication is recommended as the first-line treatment in ADHD for adults and certain age groups in childrenwith clinically significant impairment in their life (NICE, 2008). Any medication must be considered carefully along with any health concerns or other issues that would contraindicate a trial of medication. Taking into account your diagnosis and symptoms, consideration of a trial of medication may be appropriate to determine whether this would assist you with your ADHD symptoms. Medications have been found to improve attention span, task completion and self-organisation, whilst reducing impulsivity, distractibility, and restlessness.

Are private ADHD assessments worth it?

FAQ arrow

A private ADHD assessment can be beneficial for those seeking a faster diagnosis, personalized care, and an alternative to long NHS waiting times. However, it's important to factor in the costs of ongoing private treatment and the potential for shared care agreements with a GP.

UK ADHD Service work with you and your existing GP to create effective shared care agreements that can help you save money in the long run.

Will the NHS accept private ADHD diagnosis?

Some GPs may accept a private ADHD diagnosis, but this isn't guaranteed. You may still need to go through the NHS for treatment and medication, which could require a reassessment and involve waiting times.

At Private ADHD, we work with you and your existing GP to bypass these hurdles and create effective shared care agreements that can help you save money in the long run.

NHS waiting times for ADHD assessments vary by location and can be exceptionally long, with some areas facing backlogs that may take up to eight years to clear. Exploring alternatives, such as exercising your Right to Choose, could be worth considering.

"I've never been listened to since I've been able to go to the doctors myself for help... It wasn't until I seeked private help with Dr Kooner at PrivateADHD, where I was finally listened to and taken seriously. He went through everything in so much detail and diagnosed me with ADHD. We have regular catch ups to ensure the medication is working for me, which is great... Since being placed on the recommended medication by Dr Kooner, my life has changed for the better, everyone around me has seen such a positive outcome and change."
