Practices

A prescribed dose swallowed as a tablet is set to bring you into the ordinary range, not to make you high. The rise it produces is too slow and too small to be the sort of thing anybody chases.

Misuse in the research is concentrated among people who do not have ADHD and who take the medicine in ways it was never designed for, by crushing it,…

The realistic difficulty with this medicine is not misuse. It is forgetting, since part of what is being treated is the very ability to remember to do something later.

So put the reminder outside your head. A weekly pill organiser sitting on top of whatever you pick up every morning, an alarm with the name of the…

A medicine can help some people and still fail to win approval for a condition. Modafinil is the usual example, cleared for a sleep disorder and short of the bar for attention.

Approval turns on trials showing a clear enough average effect for that specific use, and an average can be respectable within a subgroup while…

Medication does not simply turn the brain up. On scans the regions that should be busy during a task get busier, and the ones that should stay quiet settle.

That detail matters more than it sounds. It says the trouble is one of aim rather than a shortage of effort, which is the opposite of what many…

Watch someone on a laboratory stop task and two things move together on medication: the fidgeting drops and the stopping gets more accurate.

Holding still and holding back turn out to run on the same machinery. That is why inhibition sits underneath so much else, from waiting your turn to…

Offered ten pounds now or twenty in an hour, plenty of people with attention difficulties take the ten and know while they are doing it that it makes no sense. The pull towards now is not a flaw of character.

It shows up in a laboratory and it shows up on a bank statement. Naming it helps, because a thing with a name can be planned around: money moved by…

You may hear that being treated as a child leaves an advantage that lasts even after you stop. It is a comforting claim and the strongest evidence does not quite bear it out.

The best known childhood trial followed its participants into their twenties. The early advantage of the assigned treatment faded, and the group…

Atomoxetine works on noradrenaline alone, which is why it can help genuinely and still feel milder than a stimulant. That is the trade being made rather than a sign it is failing.

Noradrenaline at the front of the brain helps a signal stand out from the background noise, so lifting it steadies working memory and attention.…

None of the non-stimulants should be stopped suddenly. Guanfacine and clonidine began life as blood pressure medicines, and taking them away all at once can send blood pressure sharply back up.

Atomoxetine has its own unpleasant discontinuation effects, closer to those of an antidepressant. So a break because a prescription ran out, or…

Guanfacine and clonidine arrived here sideways. Both were blood pressure medicines that doctors noticed helped with impulsivity, and the formal approval came long afterwards.

They act on receptors at the front of the brain that support working memory and holding a response back, which is a different route from the reuptake…

When a dose wears off, things can feel worse than they ever did untreated. A good deal of that is contrast rather than the medicine leaving a debt behind.

You have spent the day at one level and then meet your own baseline without warning, late in the afternoon, usually with something still to do.…

For a fair share of children, medication does more than take the edges off. Their behaviour in class comes back inside the ordinary range, which few treatments in psychiatry manage.

That matters for reasons past the symptoms themselves. A child who is no longer the one named in every staff meeting gets spoken to differently by…

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,…

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…

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…

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…

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.…
