Diagnoses of attention deficit hyperactivity disorder (ADHD) are increasing rapidly within the UK. More children and adolescents than ever are being referred for diagnosis and support, and families often face long waits and limited options once a diagnosis is made. Schools, health services and oldsters are all under increasing pressure to seek out treatments that help children genuinely manage their difficulties with attention, arousal and activity levels.
At the identical time, there is no such thing as a shortage of developing recent ideas as solutions. Some are supported by evidence, while others look promising but rest on much shakier grounds. A challenge for families is understanding which treatments are truly effective and that are driven more by hope than by hard evidence.
For many children with ADHD, stimulant medications corresponding to methylphenidate are known Highly efficient. Decades of research show that these drugs can reduce underlying symptoms and help children do higher at home and in school. For some families, medication could make a life-changing difference.
However, medicine is just not a simple selection for everybody. Many parents and young persons are concerned about negative effects, stigma or the thought of ​​taking the medication long-term. These concerns are comprehensible and sometimes lead families to hunt alternatives that feel more natural or less medical.
Against this background, brain stimulation devices have been increasingly promoted as a drug-free option for ADHD. These devices deliver very mild electrical stimulation to specific nerves or parts of the brain. They are generally considered secure, with negative effects which might be mild and short-lived, corresponding to skin irritation or tingling. Safety, nevertheless, is just not the identical as effectiveness.
One of essentially the most discussed of those technologies is trigeminal nerve stimulation (TNS). The trigeminal nerve is the biggest nerve within the face and carries signals to the brain. Devices using this approach are worn on the brow and typically deliver mild electrical pulses during sleep. The idea is that stimulating this nerve can affect the brain’s systems of attention and self-control.

This technology became the one medical device cleared by the US Food and Drug Administration for ADHD in children in 2019. For many families in search of non-drug options, regulatory clearance may suggest effectiveness, even when supporting evidence is restricted.
What is less widely understood is that the choice was based on very limited evidence. The primary study supporting the included clearance Only 62 children. Although this study reported improvement in ADHD symptoms, there was a serious weakness. Specifically, children who were to act as a comparison group received no stimulation.
It matters because expectations can Strong influence How people experience and report symptoms, especially when a treatment involves advanced technology. If children or parents can easily tell whether a tool has modified, beliefs about whether it should “work” or not may influence how improvements are perceived or reported, even when the device itself has no real effect.
Despite these limitations, FDA clearance helped legitimize the device and spur worldwide interest. TNS was marketed in private clinics, including within the UK, often at significant cost to families.
Some families bought the device overseas or through private providers, hoping it could offer advantages without medication. Meanwhile, the UK National Institute for Health and Care Excellence Within the NHS a more cautious stance has been taken before recommending such devices.
It was clear that higher evidence was needed to reply an easy query that matters deeply to families: Does TNS actually help children with ADHD?
Testing the claim
Our new study was designed to seek out We conducted a big, independent UK clinical trial of TNS, which recruited 150 children and adolescents with ADHD in London and Southampton. This made it considerably larger than the studies that got here before it. Importantly, our study was designed in order that expectations were fastidiously controlled.
Children in each groups wore devices that looked an identical, and each groups felt sensations from the device. This meant that neither the families nor the participants could easily tell whether or not they were receiving the true stimulus or the placebo version. Such a design allowed us to look at whether TNS itself exceeded expectations.
Our findings were clear. We found no evidence that trigeminal nerve stimulation improved ADHD symptoms. Children who received lively stimulation did no higher than those that received a placebo device. There was no improvement in attention, behavior, anxiety, mood or sleep.
These findings challenge earlier studies that led to regulatory clearance within the US. They also highlight why large, fastidiously designed trials are so essential, especially for treatments that generate excitement and hope. Without strong controls, it is simple to mistake expectations for effectiveness.
Technology-based mental therapies are particularly susceptible to this problem. When families are told that a tool can “correct” or “normalize” the brain activity related to ADHD, expectations can run wild. Without rigorous testing, this could result in overstating advantages and misleading families.
For families within the UK, the message from our research is a very important one. TNS appears secure, but security alone is just not enough. A treatment that does not work offers no real profit and might waste time, money, and energy away from methods which might be known to assist.
Our findings also function a reminder that official approval or marketing claims don’t at all times mean that a treatment is effective. Clearance can sometimes reflect that a tool is secure to sell, not that it has been proven to work well.
ADHD is usually a serious and lifelong condition for a lot of children and adolescents. As diagnoses proceed to extend, so does the onus to make sure families are offered support and treatment based on strong evidence – not hype, hope or premature conclusions.
_ The Conversation asked NeuroSigma, the maker of the TNS device mentioned in this text, to comment on the problems raised in this text. An organization spokeswoman said the study design mentioned within the article could have limited the flexibility to detect treatment effects. Specifically, they noted that primary final result measures relied on parent-reported diagnoses moderately than clinician-rated ADHD scales. Neurosigma says clinicians’ assessments are more reliable and fewer susceptible to bias, and say the study’s findings are subsequently not surprising.
