Generalized Anxiety Disorder Treatment
Generalized anxiety disorder is worry that runs most days for six months or more, across several parts of life, with physical signs such as restlessness, fatigue, poor concentration, irritability, muscle tension and disturbed sleep.
Also called: GAD, Generalised anxiety disorder, Chronic anxiety.
ICD-10 F41.1 · ICD-11 6B00
You cannot argue with it. You can test it.
Almost everything that fails to help anxiety is a form of arguing with it. Reassuring yourself. Checking. Researching. Being told it is fine. Each one removes the uncertainty for a few minutes, and each one trains you to ask again.
What works is the opposite move. It is unpleasant, in a specific way, for a short time. You predict what will happen. You do not check. Then you find out.
This is not a mind trick. It is the mechanism. You have to make the prediction in advance. Otherwise there is nothing for the result to disagree with. Being disagreed with is the only thing that changes a belief.
WHERE TREATMENT STARTS
Stepped, and more patient than most people want
NICE, the National Institute for Health and Care Excellence, writes the UK guidelines. It treats GAD in steps. Education and monitoring come first. Then low-intensity self-help. Only after that comes one of the stronger options. Those are cognitive behavioural therapy (CBT), applied relaxation, or a drug. The two therapies usually run for 12 to 15 weekly sessions. If someone chooses a drug, a selective serotonin reuptake inhibitor (SSRI) comes first. Sertraline is named first because it costs the least for the benefit, not because it is the strongest.
THE EXERCISE THERAPY ACTUALLY USES
Say how likely it is. Then see what happened.
This is a real exercise from therapy. It is called a behavioural experiment. It is most of what CBT for anxiety actually involves.
Here is the problem it solves. A worry is a prediction. It says something bad is going to happen. Checking, asking someone, or avoiding the situation all stop you finding out whether the prediction was right. So it never gets proved wrong. So it stays.
This exercise turns that round. You say how likely the bad outcome is BEFORE you know the answer. Then you find out what actually happened.
The gap between your number and the real one is the whole point. Anxiety predicts high. Reality usually comes in low. Seeing that gap, with your own number, is what changes the belief. And you only get to see it if you do not check.
There are three below. Pick a number first, then find out what happened.

You sent an email three hours ago. No reply.
They are annoyed with you.
The usual move is to re-read your sent folder, then send a second email softening the first one.

They replied on Thursday. They had been in meetings all week.
The prediction was not slightly wrong. It was wrong by most of the scale. That gap is the whole treatment. You only get to see it if you do not check.
A dull ache in your side, four days running.
It is something serious.
The usual move is to search it online. The worst possible answer appears within two results.

It faded by the weekend. When you did see a doctor, they called it muscular.
Searching would give relief for about ten minutes, then leave you worse than before. Not searching was harder for one day. After that the worry had nothing left to feed on.
You said something clumsy in a meeting.
People are still thinking about it.
The usual move is to ask a colleague whether it landed badly.
3
Nobody mentioned it. One person did not remember the meeting at all.
Asking would have got you a reassuring answer. It would also have taught you to ask again next time. The belief only moves when you leave it alone and it turns out to be wrong.
Three rounds is not therapy. But the shape is exactly right. A prediction made in advance. A check you did not perform. An outcome allowed to disagree with you. CBT for anxiety is mostly that, done on purpose, about twelve to fifteen times.
THE TWO HIGH-INTENSITY OPTIONS
Both are offered. They work differently.
NICE rates these two as equals. Your preference decides which you get, not how severe the anxiety is.
Cognitive behavioural therapy
This runs for 12 to 15 weekly sessions. It targets the two beliefs that keep worry running. One says the worry cannot be controlled. The other says the worry helps. CBT then tests both with experiments like the one above.
Applied relaxation
This also runs for 12 to 15 sessions. It is a genuinely different treatment, not a lesser one. It trains a physical relaxation response until you can use it the moment anxiety starts to climb.
What is not offered first
Benzodiazepines are not first-line, except briefly in a crisis. They work within the hour, and that is the problem. The body builds tolerance, so stopping becomes harder than starting was.
Why the drug and the therapy do not compete
An SSRI lowers the level the anxiety sits at. It does not change any belief. Therapy changes the beliefs, but it is hard to do when the anxiety sits very high. That is the argument for using both. It is also why adding one does not mean the other failed.
IF A DRUG IS THE ROUTE
What actually happens, in order
This follows roughly the same path as an antidepressant. There is one extra warning at the start.
Sertraline usually comes first. If it does not work, or the person cannot tolerate it, another SSRI is tried. Then a serotonin-noradrenaline reuptake inhibitor (SNRI). Pregabalin is an option after that.
Anxiety often gets WORSE during the first week or two on an SSRI. This is expected. It is also the single most common reason people stop on day five. It is much better to know this beforehand than afterwards.
The benefit builds over four to six weeks, and it keeps building for months. The early weeks do not tell you what the final result will be.
If it works, it is continued for at least a year. Stopping early is the strongest predictor of the anxiety coming back.
COMING OFF
Slowly, and not because it is addictive
The same distinction that matters for antidepressants matters here too.
Stopping an SSRI suddenly can cause withdrawal. That means dizziness, sensations like electric shocks, and anxiety returning sharper than it was originally. Reducing the dose slowly, over weeks or months, prevents most of it.
Withdrawal and relapse feel similar, and they call for opposite decisions. Withdrawal starts within days of a dose change. It includes physical symptoms that were never part of the original problem. And it eases if the dose goes back up.
None of this makes these drugs addictive. Addiction means craving the drug, needing bigger doses, and using it despite the harm. A body that has adapted and needs a slow withdrawal is a different thing entirely.
