People with ADHD tend to have lower omega-3 in their blood, and bringing low levels up has been linked with some improvement in symptoms. No convincing difference has shown up between DHA and EPA for this.

Omega-3 comes mostly from oily fish and krill, and fish is exactly what many people with texture sensitivity will not eat. Whether the shortfall…

If you are trying omega supplements, give them four to six weeks and then decide. Imaging work has picked up changes in how neurons communicate after around four weeks, which is fast as these things go.

Fixing the end point at the start protects you twice over. It takes the sting out of nothing happening by Thursday, and it stops an open ended habit…

In one trial, children were given omegas with a multivitamin, omegas alone, or neither, and after fifteen weeks everybody got both. The omega groups gained on set shifting and attention, and the children who started with nothing caught up once they crossed over.

Two features of that design are worth understanding. Everyone receiving the treatment eventually shows that the improvement follows the treatment…

Sixty two children took methylphenidate with either vitamin D or a placebo, and both groups improved. The two ADHD rating scales showed no difference between them, which leaves the positive headline resting on the clinician's judgement rather than on what parents reported.

That shape repeats all over this literature, so it is worth learning to spot. When a study reports an effect on one measure and not another, the…

People with ADHD are reported to run low on both tryptophan and homocysteine. Low homocysteine is a good thing to have, since it is the high version that damages hearts.

The reflex to correct any number under the reference range is worth resisting. Levels can be tested where there is a reason to test them. Eating a…

More clinicians now raise supplements themselves, and more of them will suggest something like omegas. The shift matters less for what gets recommended and more for what it does to disclosure.

People hide what they expect to be laughed at. Someone braced for an eye roll simply does not mention the four bottles in the kitchen cupboard, and…

Omega supplementation for ADHD began with encouraging results, including a Swedish study where about a quarter of inattentive children seemed to improve. Blinded, placebo controlled work did not reproduce it, and a Cochrane meta-analysis found no effect.

The manufacturers themselves largely moved on to other conditions, which tells you something. None of this makes omegas worthless, and levels do run…

Cutting sugar does not improve ADHD, and nor does stripping out additives. Both have been tested repeatedly, including under conditions where nobody knew which child had eaten what.

The belief survives because parties are where children eat sweets, and parties are also loud, crowded and thrilling. The sugar takes the blame for…

Megavitamins, antioxidant products such as pycnogenol and assorted trace minerals have not beaten placebo for ADHD. They stay popular on the strength of a good story about how they ought to work.

The gap between a mechanism and an outcome is the thing worth teaching, because it will still be useful when the next product appears. Ask what…

Sensory integration training is popular and it does not help ADHD. Whatever value it has elsewhere, the capacity it works on is not the one that is impaired here.

What is impaired in ADHD is holding back a response and steering your own behaviour over time. Sensory modulation is a different thing altogether.…

Chiropractic neurologic organisation training, the kind involving manipulation of the skull, has no credible theory behind it for ADHD. The main harm is not the treatment itself but the months and the money that go into it.

Families meet this because it is marketed at them at the exact moment they are most willing to try anything. Naming it plainly, once, is usually…

A child can learn a self control routine beautifully in the therapy room and not use it once all week at school. Knowing the steps and performing them under pressure are two different skills.

This is why supports that sit in the moment tend to beat supports that sit in the mind. A prompt at the point of need, a changed seat, a rule the…

With EEG neurofeedback, the weaker the study, the better the results look. Six large trials using sham feedback, with parents and teachers kept unaware of who received what, found nothing beyond placebo.

That shrinking with rigour is itself the finding. Blinding matters especially here because the outcome is a rating made by adults who have watched…

Brain training makes you better at the game, and at things that resemble the game. It does not seem to reach the parts of life you bought it for.

Cogmed, the several hundred apps, the balance based programmes: they all hit the same wall when someone independent tests them with a proper control…

One senior researcher in this field is approached by ADHD app startups roughly once a month and no longer takes part, on the view that the companies are not seriously trying to build something that works.

You do not have to share his judgement to borrow the question. Before paying for a digital product, ask who tested it, whether those testers were…
