ADHD Treatment: What Works
Attention-deficit/hyperactivity disorder (ADHD) is a developmental difference in attention regulation, impulse control and activity level, present before age twelve and showing up in more than one setting.
Also called: Attention-Deficit/Hyperactivity Disorder, Attention deficit hyperactivity disorder, ADD, Attention deficit disorder.
ICD-10 F90 · ICD-11 6A05
It works within the hour. Finding the dose takes weeks.
Depression medication is a slow story. The drug reaches its target within hours. The person then waits weeks to feel anything, because the brain has to change first.
ADHD medication is the opposite. A stimulant starts working within about thirty to ninety minutes, and it wears off the same day. There is no six-week wait.
The weeks go somewhere else instead. They go into finding the right dose, one step at a time. The right dose is different for every person, and no test can tell you it in advance.
WHERE TREATMENT STARTS
Support first, then medication if it is still needed
NICE, the National Institute for Health and Care Excellence, is the body that writes the UK guidelines. It starts with information, and with practical changes at home, at school or at work. Medication is offered only when ADHD still causes real problems after that.
For children aged 5 and over, methylphenidate is the first medication. For adults, it is either lisdexamfetamine or methylphenidate. For children under 5, parent training comes first, and medication is rarely used at all.
THE PART NOBODY DESCRIBES
Find the dose.
Starting ADHD medication is not one prescription. It is a process, and doctors call it titration. You start on a low dose. You raise it one step at a time, usually about every week. At each step you check how things are going.
Watch the two bars below as you climb. Focus is one. Side effects are the other. They do not move together. Focus improves for a while, then stops improving. Side effects keep climbing the whole way. Those include a lower appetite, worse sleep and a faster heartbeat. Past a certain point, more medicine can also make thinking rigid and flat.
So the goal is not the highest dose. The goal is the step where focus has stopped getting better, and side effects have not yet taken over. That step is different for every person. Try all three people below and compare where their best step lands.
Pick a person, then raise the dose one step at a time. Go back down if a step makes things worse.

Good intentions every morning. By ten, the plan is gone.
A little easier to start. Still drifts after lunch.
Starts the report without a fight. Notices when attention slips, and comes back.
About the same focus as step 2. Lunch gets skipped.
Focus is no better. Sleep comes later. Feels wired.
Locked onto one thing and cannot switch. Quiet and flat, not like themselves.
Person A's best dose was step 2. Going higher added no focus at all. It only added side effects. At the top step it made their thinking rigid.

Good intentions every morning. By ten, the plan is gone.
No real change yet.
Some mornings are better than others.
Clearly better. Still loses the afternoon.
The whole working day holds together. Appetite a little lower.
No better than step 4. Heart feels faster.
Person B needed step 4 to get the result Person A got at step 2. That does not mean their ADHD is worse. Bodies process these drugs at different speeds, and nobody can tell which you are in advance.

Good intentions every morning. By ten, the plan is gone.
Nothing much changes.
Maybe slightly better. Hard to tell.
Not better. Stomach aches.
Still not better. Sleeping badly.
More side effects and no benefit. Time to stop climbing.
This medicine did not work for Person C. That is common. About 7 in 10 people respond to the first stimulant they try. When both families of stimulant are tried, about 9 in 10 respond. So the next move here is to switch drug, not to keep climbing.
Real titration takes about six weeks. A doctor checks heart rate, blood pressure and weight along the way. The shape is the same as the one here. Small steps, an honest report at each step, and going back down when a step makes things worse.
NOT ONLY MEDICATION
What else has evidence
Medication is the strongest single treatment for ADHD. It was never meant to be the only one.
Cognitive behavioural therapy (CBT) for adults
This is therapy built for ADHD. It works on planning and on handling time. It also works on the avoidance and shame that build up over years of struggling with no name for the problem.
Parent training
This is the first treatment for young children. It teaches clear routines, short instructions and specific praise. It is a treatment, not a judgement of the parent.
What lacks good evidence
Neurofeedback stops working once the people rating it do not know who received it. Omega-3 supplements and removing food dyes both show only small effects.
Why medication and skills work together
Medication makes it easier to start a task and stay on it. That makes new habits possible to learn in the first place. The habits then keep working in the evening, after the dose has worn off. Each one covers a gap the other leaves.
IF MEDICATION IS THE ROUTE
What actually happens, in order
This is faster than most psychiatric medication, and it involves the doctor more.
Heart rate, blood pressure, height and weight are all checked before starting.
A stimulant is started at a low dose. It is then raised step by step over about six weeks.
If the first drug does not work after a fair trial, the other family of stimulant is tried. Most people who do not respond to one do respond to the other.
Non-stimulants are the next option. Atomoxetine and guanfacine are the two main ones. Unlike stimulants, they take several weeks to build up in the body.
The common side effects are a lower appetite, trouble sleeping and a faster heartbeat. They often ease off. They are also the main reason doses get changed.
OVER YEARS
What the long-term data shows
The most common fear about ADHD medication is what it does in the long run.
One study followed nearly 150,000 people in Sweden. Starting ADHD medication was linked to about a fifth fewer deaths over the next two years. Most of that came from fewer accidents.
Other studies followed children with ADHD for years. Stimulant treatment did not raise their risk of drug or alcohol problems later in life.
These studies watched what happened. They were not controlled trials, so they show a link rather than proof. They do point the same way as the short-term trials.
COMING OFF
Simpler than with antidepressants
Stimulants leave the body within a day, so stopping works differently.
There is usually no long reduction period, as there is with SSRIs. The effect ends the same day.
What comes back is the ADHD itself, not withdrawal. That is useful information, because it shows you what the medication was doing.
NICE recommends a review at least once a year. That review can include a planned break, to check whether the medication is still needed.
