Methylphenidate and amphetamine are not two names for the same thing. One mainly blocks dopamine from being taken back up, and the other does that and pushes more of it out as well.

That extra step is why the amphetamines tend to produce somewhat larger average effects, and why somebody who got nothing from one can do well on the…

The stimulants get described as dopamine drugs, and they touch noradrenaline as well. That second effect is what led to medicines aimed at noradrenaline on its own.

Noradrenaline at the front of the brain helps hold a signal steady against background noise, which is a plain description of what working memory…

The alpha-2 medicines work differently again. Picture small ports on the receiving cell that let noise in and let signal leak away, and a medicine that closes them.

Because they act on how clear the signal is rather than on how much transmitter is around, they tend to help most with restlessness, temper and tics,…

The potential for misuse belongs to one of the three families rather than to ADHD medicines generally. The stimulants reach the reward circuitry and the others do not.

That gives a clear answer where there is a substance history in the house, or a worry about tablets going missing at school. Say plainly that a…

There is more about focus, starting, and adhd than the practices: the focus, starting, and adhd area has the themes and the courses too.

There has been no genuinely new stimulant molecule for decades. What is new is almost always the delivery: how fast it arrives, how long it lasts, whether it can be sprinkled or chewed.

So when something is described as a new medication, the useful question is about its shape across the day rather than a new mechanism. That is no…

New medicines will probably come from genetics and from the chemistry of the frontal lobes. None of it is close enough to be worth waiting for.

Compounds acting on particular dopamine receptors, on glutamate, and on nicotinic pathways have all been proposed, and the nicotinic route has…

A plain immediate release tablet works for roughly three to five hours, so an ordinary school day needs two or three of them. If the afternoons keep falling apart, that gap is worth naming out loud with the prescriber rather than reading it as failure.

Repeat dosing in the middle of the day asks a lot of everyone. Somebody has to remember, the school office has to hold a controlled drug, and a child…

Some capsules are tiny pumps. A coating of powder gives an early lift, then water seeps in and slowly pushes a gel of medicine out through a laser drilled hole, with a little more strength held back for later in the day.

Knowing this changes what you expect from it. The rise is gentle rather than sudden, the afternoon is deliberately given a slightly stronger push…

If the patch brings a rash, it is usually a reaction to the medicine passing through the skin rather than to the sticky backing. Worth knowing, because switching brand or trying a kinder tape will not fix it.

Skin has its own way of reacting to something held against it for hours at a time, and that reaction stays local. Saying this early saves a family a…

A rash from the patch does not put the same medicine out of reach in tablet form. Plenty of people react to it on the skin and take it by mouth with no trouble at all.

It is easy to write a whole drug into the allergy box after a bad experience with a patch, and that single line can close off a first choice…

One of the amphetamine medicines arrives switched off. It is bound to a simple building block of protein and only wakes up once the body cuts the two apart, which is why crushing or snorting it gets you nowhere faster.

That was designed in on purpose. Because the gate is an enzyme rather than a coating, there is no way to get in front of it, and the medicine comes…

That locked design turned out to carry an unplanned kindness: a somewhat longer day, and for many teenagers and adults a softer start and a softer finish, with less jaw clenching and less of the ragged hour when it wears off.

The edges often matter more to the person taking the medicine than the peak does. If you dread the late afternoon drop, or notice your jaw aching by…

Capsules are not the only option any more. Long acting liquids and chewable forms exist, so a child who cannot manage a pill does not have to be left with nothing or with a dose that runs out by lunchtime.

Not being able to swallow a capsule stops being a small detail when it is the reason treatment ended. Ask specifically what comes as a liquid or a…

Doing badly on one long acting product does not mean the medicine inside it was wrong for you. The same molecule in a different capsule can behave differently enough to be worth trying before anyone gives up on it.

What gets described as the medicine not working is often the shape of the day being wrong: too slow to start, too abrupt at the end, strongest at the…

People usually stop for one of three reasons: the side effects are not worth it, the price is too high, or the dose was never raised far enough to do anything. The last one is the saddest, because it makes a workable medicine look useless.

If a trial ended with the words nothing happened, it is worth going back over what dose was actually reached and for how long it was held there. A…

Before anyone concludes that medication does not work for you, check what dose was actually reached. Doses in general practice often stay lower than a specialist would use, and a fair share of so called non responders respond once the dose goes up.

You are allowed to ask this, gently and without any accusation in it: what was the highest dose tried, and how long did it stay there? A trial that…

If one family of stimulant did nothing, or felt awful, that tells you very little about the other. Methylphenidate and amphetamine work in overlapping but different ways, and plenty of people who do badly on one do well on the other.

Stopping after a single class is one of the commonest routes to believing that nothing helps. Trying the second one is a normal next step rather than…

The growth effect is usually small: something like a couple of pounds and a centimetre or two less than expected in the first year or two, with most children catching up afterwards. Knowing the size of it helps, because both blank reassurance and quiet dread are worse than the actual number.

Height and weight get plotted at review appointments for exactly this reason, so ask to see the chart rather than carrying a vague worry between…

Breaks from medication at weekends or over the summer are a tool for a particular problem, usually growth, rather than something everyone ought to be doing. Where growth is fine, a holiday tends to cost more than it gains.

The days without medicine are not neutral days. They are often the days with more accidents, more falling out with people, and more of the shame that…

You may hear that staying on stimulant medication for years can shift the structure of the brain itself, not only the day. It is a real line of research and it is still an open question, so hold it lightly.

The work points at a handful of regions involved in attention and movement, and at a minority of people who stayed on treatment for several years.…
