Focus, starting, and ADHD

There is no brain scan, EEG trace or blood test that can tell you whether someone has ADHD. Anything sold as an objective biological test for it is promising more than the science can give.

Group differences do exist, including in the theta to beta balance, but a difference that appears when you average hundreds of people cannot identify…

Balance difficulties do turn up more often in ADHD, by something like half again. That is a fact about company, not about cause, and it does not turn balance training into a treatment.

Plenty of things could sit behind a link like that. More falls and knocks, more risk taken, or genetics feeding both at once. Working on balance…

Try swapping the word picky for particular. A fair number of people with ADHD have more densely packed taste buds, so the bitterness in a sprout arrives at full volume.

That changes what is going on at the table. A child is not refusing in order to be difficult, they are tasting something stronger than you are.…

The amount in a capsule can vary from bottle to bottle, and sometimes between capsules in the same bottle. Undeclared fillers have been found in them too.

This matters most when you are trying to work out whether something helps you. A good month followed by a flat one may be two different products…

Kava can damage the liver at a high enough dose, badly enough that some countries have banned it. Herbal is not a synonym for gentle.

The unnerving part is how quiet liver damage is. Someone self medicating anxiety with kava can be accumulating harm and feel nothing at all until it…

Vitamin C cannot really be stockpiled, since the excess leaves in your urine. A, D, E and K are stored in fat, so a large daily dose keeps adding to itself.

Vitamin D is where this bites at the moment, after a lot of people started taking big amounts on their own during the pandemic years. If you are…

Omega supplements thin the blood, so they usually do not belong alongside warfarin. Bruising easily is often the first thing anyone notices.

One clinician worked out that her husband's bruising came from taking omegas on top of his Coumadin, and it settled once his doctor told him to stop.…

If fish oil gives you those horrible repeats all afternoon, that is a fixable problem rather than a reason to stop. Keep the capsules in the freezer, ask about an enteric coated version, or try a flavoured liquid.

Sticking with something usually fails for small unglamorous reasons like this. Someone with a sensitive palate will not last four weeks with an…

Neurofeedback rests on a tidy idea: in ADHD the slower theta rhythm shows up when the faster beta rhythm should be running, so the training rewards you for shifting the balance. Knowing the idea is worth a few minutes, because it is what the brochure is built on.

Electrodes sit on the scalp, a screen animates when the signal moves the wanted way, and the person practises staying in a state of relaxed…

Ask what happens after the course ends, not only what happens during it. A gain that fades once the sessions stop was probably never a change in the person.

Neurofeedback tends to look decent while it is being delivered and then drift back, and the studies that followed people afterwards did not find…

Before committing to a course that runs into thousands, set the same money next to the other things it could buy. Tutoring, a proper assessment, a medication review and a well tested psychosocial programme all sit in the same envelope.

Neurofeedback courses often run for a month or more, insurers rarely pay, and the training of whoever delivers it varies a great deal. The cost is…

When you read that a treatment worked, look for who judged the improvement and whether they knew what the child had been given. In much of this literature, they knew.

The design to look for is a sham condition, where everybody goes through the same routine and only some receive the active ingredient, with the…

Brain training games make you better at the game. Sadly, that improvement tends to stay inside the game.

Sorting shapes faster or planning a conveyor belt more smoothly comes from learning the task, not from stretching a capacity, so the classroom and…

Regulators let devices through by several different routes, and only some of them mean what a family assumes. A game cleared for further investigation has not passed the bar a medicine passes.

The word approval carries an authority that advertising borrows freely, and device pathways are shorter and lighter than the ones drugs travel. It is…

Programmes built on tones through headphones and balance drills have not been shown to help ADHD. If a child does seem steadier during them, the likeliest reason is that something is occupying the part of them that goes looking for stimulation.

That effect is real enough, and it is cheap to get elsewhere. A walk, a job with the hands, background sound they choose themselves, all of it…

If someone has genuine positional vertigo, get it treated, and do not expect the treatment to touch their ADHD. Both things can be true at the same time.

Benign paroxysmal positional vertigo often follows a sinus infection or a bang to the head, and it responds well to repositioning manoeuvres that…

Several professional bodies came together to say that vision therapy is not a treatment for ADHD. A joint statement like that is unusual, and it is worth quoting to a family word for word.

Convergence problems, where the eyes struggle to work together on something close up, are a little more common in ADHD and deserve treating in their…

Turn the socks inside out so the seam sits away from the toes, cut the label out and print the size onto the fabric instead, and look at seamless clothing. These cost pennies against a course of therapy and they work by teatime.

A scratchy seam or a stiff tag is a small thing that keeps announcing itself all day, and every announcement takes a piece of attention with it.…

Weight across the body settles a lot of people and sends some of them to sleep quickly. It is a preference though, not a remedy, and for others it feels like being closed in.

If you try it, watch what actually happens rather than what is supposed to happen. Some people have wanted pressure, small dark spaces and being…

Keep something to eat and drink within reach for hard conversations. Handing someone a biscuit and a glass of water often settles a room faster than any instruction does.

Part of why it works is that nobody has to be told how. A person too wound up to follow a breathing exercise can still take a sip and chew. Sharing…

Being told you are too sensitive is usually someone else's comfort talking. Feeling things strongly is not the problem to solve; what to do once the feeling has arrived is.

Both halves have to be said together. Validation on its own leaves a person flooded with permission and no handles. Teaching control on its own joins…

Since 1994, supplements have not had to satisfy a regulator before going on sale. Nobody checked the bottle in your hand the way they check a prescription.

The gap is wider than most people expect. Drug factories get unannounced inspections and can be shut down on the spot; supplement makers do not face…

Natural is not a regulated word: anyone can print it next to a picture of a leaf, on anything at all. Organic in the USDA sense does have a legal definition sitting behind it.

The same goes for the reassuring line about following good manufacturing practices, which describes what a company aims at rather than what an…

Kava, valerian, St John's wort, ginkgo, ginseng and the proprietary blends have not shown benefit for ADHD in trials that matched the amount in every capsule and kept both the person handing them out and the person rating behaviour unaware of who got what.

Those two design details are most of the story. Ordinary use has dose wobble and expectation running through it, and expectation is powerful,…

If a stimulant that was working suddenly is not, ask what else the person has started taking before deciding the dose needs to go up.

One woman's Adderall went flat while she was on a herbal supplement and came back to its usual self once she stopped it. Herbs can shift stomach…

If a little helps then a lot must help more is not really a supplement thought. It is an addiction shaped thought that has wandered into the vitamin aisle.

Moderation tends not to be a natural strength with ADHD, and this is one place where that costs something. Name it early, before a safe dose has…

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…

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…
