Doctors in the UK say they are increasingly concerned that a global shortage of ADHD drugs is leading to children going without medication and missing school, and to adults self-medicating with alcohol instead.
How common is ADHD? It was long assumed that between 5% and 6% of children have ADHD, but "the rates, in practice, are often higher", said Sven Bölte, a professor of child psychiatric science at Sweden's Karolinska Institutet, on The Conversation.
Latest NHS figures show that 230,000 people in England are taking medication to treat ADHD, "including 110,000 children and teenagers", said The Times. But the true number affected by some form of ADHD "might be as many as 2.2 million", said the Nuffield Trust health think-tank.
Why the shortage in medication? Five types of medicine are licensed for the treatment of ADHD in the UK, the "most common of which", said The Times, is methylphenidate, sold under the brand names Concerta and Ritalin.
Rising demand is a key cause of the shortages. Prescriptions have tripled over the past decade as the condition has become more widely diagnosed. The "main increase" in diagnoses is among "young women aged 25 to 40", said The Guardian.
Are we over-treating ADHD? Part of the problem is that ADHD is currently treated as "something you either have or you don't", said The Economist. Treating diagnosed people as "ill" puts a strain on healthcare and special-needs-education systems, while forcing people to "fit in with normal", which can "cause anxiety and depression".
But this "binary view" of ADHD is "no longer supported by science". Researchers have realised that there is no such thing as the "ADHD brain". The characteristics around which an ADHD diagnosis is made – attention problems, impulsivity, difficulty organising daily life – span a "wide spectrum of severity, much like ordinary human traits".
For those at the severe end of the spectrum, "medication and therapy can be crucial for finishing school or holding on to a job", but for most people with ADHD, the symptoms are "mild enough to disappear when their environment plays to their strengths". |
