Cases of attention deficit hyperactivity disorder are rocketing, but what's the cause? Fortunately, we now have a better understanding of the condition - and how to identify those who have it #ADHDnewscientist.com/article/mg2583…
It seems like everyone is talking about ADHD at the moment, from people down the pub to online influencers
Posts on tiktok with the #ADHD have 23 billion views. And we know that diagnoses are rising too
But what’s behind all this interest?
Caroline Williams (@ScienceCaroline) – who suspects she has ADHD herself – wanted to find out
Are people who are a bit fidgety jumping on the bandwagon? Or have we actually been under-diagnosing people for years?
There are reasons to worry about over-diagnosing ADHD
In the US, services that offer a diagnosis and stimulant medication to treat the condition have been springing up. In theory, they have an incentive to over-diagnose people
The best way to see if we are over-diagnosing is to look at how many people we expect to have #ADHD
Studies that looked at random groups of people to see how many have ADHD symptoms suggest that around 3 per cent of adults and 5 per cent of children meet the criteria
When we look at data on diagnosis rates, England the Australia are way below that, while the US is roughly where we would expect
Experts told @ScienceCaroline that many of the people who think they have ADHD and seek a diagnosis are often right
We’re also getting better at finding out quickly who really has ADHD
Traditionally, the diagnosis depends on the opinion of a doctor. But these days there are cognitive tests can help us rule people in and out more objectively
Of course, not everyone sees ADHD as a problem
People who have it are often highly creative and, counterintuitively, have the ability to hyperfocus on topics that really interest them
In fact, some say the condition ought to be renamed – it’s not so much a deficit of attention, but the a difficulty with controlling where it is directed

Forget vanity, there's a much better reason to want to banish wrinkles - a new theory suggests skin ageing is causing widespread ageing throughout your body and brain newscientist.com/article/236609…
As skin ages, it degenerates dramatically. In the epidermis, stem cell proliferation slows down, leading to progressive thinning – we lose up to half this layer over our lifetime – and a roughening of its surface
On top of this, as skin ages, more and more cells enter a zombie-like state called senescence
This is bad news, says @claudiacavadas, as the cells pump out a toxic cocktail of inflammatory proteins that damage surrounding cells and connective tissue
Fifty years ago, Bernard Carr wrote in New Scientist about the mounting evidence for black holes. Now, evidence for these objects is incontrovertible, and Carr is back writing for us – this time about black holes older than the universe newscientist.com/article/mg2573…
In a lifetime of tree climbing, Nalini Nadkarni has helped expose the secrets of cloud forests – and as the perils now facing them newscientist.com/article/mg2573…
Meet the cloud forest researcher and secular “missionary” for ecology who has a Barbie doll made in her image newscientist.com/article/mg2573…
When Nalini Nadkarni first ventured into the canopy of a cloud forest four decades ago, almost nothing was known about this unique ecosystem
To explore it, she and a small group of pioneers had to develop special tree-climbing techniques, which have allowed her and others to unlock the mysteries of forest canopy biology
What qualifies as trauma has become a hotly debated issue, with implications for treating people who experience PTSD newscientist.com/article/mg2543…
Giving birth. A car accident. Racial abuse. Many of us feel we have experienced things we would describe as traumatic
Add in a pandemic and experts warned that a mental health crisis was in the making, with cases of post-traumatic stress disorder predicted to soar
In fact, most of these things don’t actually count as trauma. Research by @giorgiobee at @Columbia has shown that, given time, most of us will recover even from the most horrifying experiences
