ADHD Diagnosis

I beg to move,

That this House has considered ADHD diagnosis.

It is a pleasure to serve with you in the Chair, Ms Vaz. This debate is about how pathways to attention deficit hyperactivity disorder diagnosis might be improved, including by offering screening in schools, so that people can access the right support in good time.

We all have a pretty good idea of what ADHD means, but I am here because a 19-year-old constituent of mine, Matty Lock, took his own life in September 2023. He was diagnosed with autism at the age of 14, but he and his parents, Christine and Richard, who are here this afternoon, did not know about his ADHD until much later. In Matty’s memory, Christine and Richard have set up the Matthew Lock ADHD Charity, and they have been part of the independent taskforce. One of the things that the taskforce has done—this has been accepted by the NHS—is to highlight the proven link between suicide and ADHD. The prevalence of ADHD is 10 times higher among men attempting to take their own lives.

Let me say a few words about Matty. I knew him because he was very interested in politics. He had become a town and parish councillor, and he had campaigned hard with me for some time. Those of us who knew him through politics believed that he would be in this place before much longer. It is very, very sad that that was not to be.

Matty was known on television as “The Vac Mat” for his repairs of vacuum cleaners and his advocacy of domestic appliances on “This Morning”. He was everywhere in the community of Maghull—clearing up and playing his part. He was a real, strong advocate of the community that he grew up and lived in.

Matty’s ADHD was linked to how hyperactive he was. We know that people with ADHD are restless, lack concentration, are impulsive, act without thinking and always talk over others—actually, as I go through the list, I can think of nearly 650 people in this place who have a lot in common with that description.

What is the impact of having ADHD? We know that it leads to a significant number of school exclusions and very high drop-out rates. We know about the link with addiction, and that the prevalence of ADHD among people in prison is five to 10 times higher than among people outside. Sadly, we also know about the link with suicide.

NHS figures suggest that about 700,000 people are waiting for a diagnosis, and that many of them have waited for several years. Nearly two thirds of those people have been waiting for more than a year. The economic cost is estimated to be about £17 billion a year.

The hon. Gentleman is making a powerful speech that has affected us all. In November 2025, NHS Surrey Heartlands integrated care board in my constituency paused assessments on the Right to Choose pathway until April 2026, which has caused major disruption. My constituent’s daughter does not know when she will be seen or if she will be seen at all. I have talked to the ICB and I know that there has been a massive increase in referrals for ADHD, so does the hon. Gentleman agree that the Government must set out plans to improve local NHS provision of ADHD assessments?

[Bill Esterson]

The example of the hon. Member’s ICB is typical of ICBs around the country. The purpose of this debate is to raise the issue with the Minister and highlight how important it is to improve diagnosis and speed up how quickly people can get access to treatment and medication.
