Generalised anxiety disorder (GAD) is characterised by persistent, excessive worry about a wide range of everyday concerns — not just one specific thing. It affects around 5% of the UK population and often goes unrecognised because worry can seem like a personality trait rather than a treatable condition. With the right therapy, most people with GAD make significant and lasting improvements.
GAD involves chronic, uncontrollable worry that is difficult to switch off and feels disproportionate to the actual situation. Unlike situational anxiety — which is a normal response to specific stressors — GAD involves generalised worry that jumps from topic to topic and persists even when there is nothing concrete to worry about.
People with GAD often describe their minds as being in a constant state of "what if" — anticipating problems, planning for worst-case scenarios, and finding it very difficult to tolerate uncertainty. The worry itself is often experienced as purposeful ("if I worry about it, I'll be prepared") even though it rarely leads to productive problem-solving.
GAD is frequently accompanied by physical symptoms — muscle tension, fatigue, headaches and sleep difficulties — which can lead to it being attributed to physical causes rather than anxiety.
NICE diagnostic criteria for GAD include excessive anxiety and worry on more days than not for at least six months, along with three or more of the following:
The worry should be difficult to control and cause significant distress or impairment in daily functioning.
CBT is the most evidenced treatment for GAD and is recommended as a first-line treatment by NICE. The CBT model for GAD specifically addresses the role of worry itself — including positive beliefs about worry ("worrying helps me prepare") and negative beliefs ("I can't cope with uncertainty") — rather than tackling each worry topic individually.
Key elements include:
Other effective approaches include:
GAD is one of the most treatable anxiety conditions, yet many people live with it for years without seeking help — partly because persistent worry can feel like just "how I am". If anxiety and worry are affecting your sleep, relationships, work or quality of life on a regular basis, therapy can make a real difference.
You can self-refer to NHS IAPT services in England or speak to your GP. CBT for GAD is widely available both through the NHS and privately.
We don't currently have any therapies mapped to this condition.
Normal worry tends to be time-limited, triggered by specific concerns, and resolves when the situation resolves. GAD involves worry that is persistent, difficult to control, covers multiple areas of life, and causes significant distress or functional impairment even in the absence of objective threat. The worry in GAD is often about the worry itself.
Yes — GAD frequently causes significant physical symptoms including muscle tension, headaches, fatigue, nausea, and sleep disturbance. These physical symptoms are a direct result of chronic physiological arousal. Some people with GAD seek medical help for physical symptoms for years before the underlying anxiety is identified.
A typical course of CBT for GAD runs 12–15 sessions. Progress is often gradual, as reducing habitual worry requires consistent practice between sessions. Most people see meaningful improvement within 8–10 sessions.
There is evidence of a genetic component to GAD, meaning it can run in families. However, environmental factors — including early experiences, learned patterns of worry, and life stressors — play a significant role. Having a genetic predisposition does not mean GAD is inevitable or untreatable.
Yes — SSRIs and SNRIs are recommended by NICE for GAD and can be effective, particularly for moderate to severe presentations. They work best when combined with CBT rather than used alone. Benzodiazepines are sometimes prescribed short-term but are not recommended for long-term use due to dependency risk.
