Generalised Anxiety Disorder
Red Flags — act before continuing history
| Red flag | Why dangerous | Action |
|---|---|---|
| Active suicidal ideation with plan or intent | GAD with comorbid depression carries significant suicide risk. PHQ-9 ≥15 with positive item 9 and specificity of plan requires same-day crisis assessment. | Same-day CRHT / 136 / A&E |
| New-onset anxiety in older adult (>50) without psychological precipitant | Organic suspicion mandatory: hyperthyroidism, cardiac arrhythmia, phaeochromocytoma, early dementia, alcohol withdrawal. GAD rarely presents de novo after 50 without a precipitant. | Urgent bloods + ECG within 1 week |
| Palpitations + syncope or near-syncope + anxiety | Cardiac arrhythmia (AF, SVT, WPW, prolonged QTc) causing palpitations can trigger anxiety — the anxiety is a response, not the cause. Syncope with palpitations must have cardiac cause excluded before attributing to anxiety. | ECG same day + cardiology |
| Episodic severe hypertension + sweating + headache + palpitations | Phaeochromocytoma presents with paroxysmal episodes of severe hypertension, diaphoresis, headache, and palpitations — frequently misattributed to anxiety. Missing it is catastrophic: hypertensive crisis, stroke, cardiac arrest. | Urgent endocrinology — specialist-directed testing |
| Rapid weight loss + anxiety + heat intolerance + tremor | Hyperthyroidism or thyroid storm can present as severe anxiety with weight loss, heat intolerance, and palpitations. TSH mandatory; if very suppressed and systemically unwell → urgent endocrinology. | Urgent TSH + free T4 + endocrinology if severe |
| Anxiety + focal neurological symptoms (headache, weakness, vision change) | CNS pathology (space-occupying lesion, encephalitis, temporal lobe epilepsy) can present with anxiety and personality change as early symptoms. New anxiety with focal neurology requires urgent imaging. | Urgent CT/MRI head + neurology referral |
| Severe self-neglect or inability to care for dependants due to anxiety | GAD so severe the patient cannot perform ADLs or care for dependent children constitutes a functional emergency requiring same-day psychiatric assessment and social services involvement. | Same-day psychiatric assessment + safeguarding |
Safeguarding Considerations — Consider in Every Consultation
🏠 Domestic Abuse / Coercive Control
- Chronic anxiety maintained by ongoing threat in the home environment
- Partner insists on attending or speaks on behalf of the patient
- Anxiety significantly worse when home or relationship safety is asked about
- History of repeated anxiety consultations without improvement — consider ongoing threat
- Use the DASH risk assessment if domestic abuse is suspected
👶 Children in the Household
- Parent with severe GAD may be unable to meet children's emotional and physical needs
- Parental anxiety transmitted to children — anxious parenting amplifies childhood anxiety
- Review whether children are attending school and developing appropriately
- Involve health visitor or school nurse if concern about parenting capacity
👴 Carer and Elder Safeguarding
- Carer anxiety about the person they care for — burnout and risk of harm to dependant
- Older adult with anxiety and cognitive decline — capacity assessment may be needed
- Financial abuse anxiety — patient coerced into financial decisions causing significant anxiety
- Isolated older adult with anxiety and no social support — review safety at home
⚠ Self-Harm and Suicide Risk
- GAD with comorbid depression — assess suicidal ideation at every appointment
- Anxiety with alcohol or substance use — increased suicide risk; impaired inhibition
- Self-medication with benzodiazepines or alcohol — escalating misuse pattern
- Social isolation + hopelessness + GAD = significant suicide risk constellation
🧠 Intolerance of Uncertainty
The core cognitive vulnerability in GAD is intolerance of uncertainty — the belief that uncertain situations are inherently threatening and must be resolved. Patients with GAD are hypervigilant to ambiguity and experience uncertainty as intolerable. This drives worry as a strategy to mentally "solve" uncertain situations in advance.
"When something is uncertain — when you don't know how something will turn out — how does that feel? Can you tolerate not knowing, or does it feel unbearable?"Intolerance of uncertainty is directly addressed in CBT for GAD. Identifying it frames CBT as treating the root cause, not just symptoms.
🔥 Chronic Stress and Life Circumstances
Ongoing objective stressors — financial precarity, caring responsibilities, job insecurity, relationship conflict, housing instability — maintain anxiety biologically through sustained HPA axis activation. Treating anxiety without addressing these factors is like bailing out a leaking boat.
"When you think about where the worry comes from — what are the main things in your life right now that feel most uncertain or threatening?"Address objective stressors: Citizens Advice, social prescribing, occupational health. Acknowledging their validity in the consultation itself is therapeutic.
💔 Childhood and Early Adversity
Adverse childhood experiences significantly increase the risk of adult GAD via epigenetic programming of the HPA axis and hypervigilance to threat. A history of early adversity may indicate that standard CBT is insufficient and trauma-focused therapy is needed.
"Sometimes anxiety in adulthood is connected to experiences people have had much earlier in their lives. Is that something that feels relevant to you at all?"If significant early adversity: EMDR or trauma-focused CBT may be more appropriate than standard CBT; NHS Talking Therapies can provide this.
🧭 Beliefs About Worry
Patients with GAD commonly hold positive metacognitive beliefs about worry — "worrying means I'm responsible," "if I worry about it, I'll be prepared," or "worrying keeps the people I love safe." These beliefs make worry feel purposeful and difficult to relinquish. CBT for GAD directly addresses these metacognitive beliefs.
"When you worry, does it ever feel like the worry is doing something useful — like it's keeping you prepared, or keeping bad things from happening?"Identifying positive worry beliefs helps explain why the patient hasn't "just stopped" and frames CBT as teaching a different relationship with uncertainty.
😓 Shame and Stigma
Patients with GAD often carry profound shame — they believe they should be able to control their own minds, and that anxiety reflects weakness or failure. This shame delays help-seeking by years and causes patients to resist psychiatric diagnoses and psychological treatments.
"Sometimes people feel a lot of shame about anxiety — like they should just be able to pull themselves together. Has that been part of your experience?"Psychoeducation — "anxiety is a biological survival system that's become overtuned, not a personality flaw" — reduces shame and improves treatment engagement.
🔄 Reassurance-Seeking
Excessive reassurance-seeking — from GPs, family members, or online — provides temporary relief but maintains anxiety by reinforcing the belief that reassurance is necessary for safety. It is a form of behavioural avoidance that prevents natural habituation.
"When you feel anxious, do you find yourself checking things, asking people to reassure you, or going online to look things up? Does that help in the moment but the worry comes back quickly?"Gently limiting reassurance-seeking in primary care — agreeing a maximum number of consultations per month — is clinically beneficial, not dismissive.

Stepped Care — Primary Care
NICE CG113 stepped care pathway- GAD-7 5–9 (mild) — first presentationStep 2: psychoeducation + self-help + lifestyle + NHS Talking Therapies referral (low intensity)
- Marked symptoms or impairment (GAD-7 typically ≥10) without red flagsStep 3: high-intensity CBT/applied relaxation or an SSRI (sertraline) by preference, or both; early SSRI review within 1–2 weeks
- GAD not responding to Step 3 after adequate trialStep 4: consider SNRI, pregabalin (specialist), or CMHT referral
- GAD with comorbid mild depression (PHQ-9 <15)SSRI addresses both; NHS Talking Therapies; monthly review; PHQ-9 monitoring
- Prescribing SSRI and booking 6-week follow-up without a 2-week safety review
- Not excluding organic cause (TSH, ECG) in patient with palpitations and new-onset anxiety
- Offering benzodiazepine as primary treatment for GAD without dependence discussion
- Sending home patient with active suicidal ideation and a prescription alone
- No examination at all — even in a "psychological" presentation
- Examining but not communicating findings to the patient
- Missing thyroid examination in a patient with palpitations, tremor, and weight loss
- Not checking pulse and BP before prescribing an SSRI
- Not using GAD-7 as a validated tool — clinical impression alone is not equivalent
- Not using PHQ-9 — missing comorbid depression in 50–70% of cases
- Ordering extensive investigation panel that reinforces health anxiety
- Not ordering TSH in a patient with new anxiety + palpitations + weight change
"What I think is happening is that your brain's alarm system — the part designed to keep you safe from danger — has become overtuned. When it fires, your body prepares for danger: your heart rate increases, your breathing speeds up, your muscles tense, and your thinking narrows to scan for threats. That's why you get the palpitations, the chest tightness, the headaches, and the constant feeling that something terrible is about to happen. The difficulty is that this system keeps firing when there's no actual danger — it's triggered by uncertainty, by thoughts, by ordinary daily situations. That's generalised anxiety disorder: a very treatable condition where the brain's threat-detection system has become hypersensitive. It doesn't mean you're weak or 'mad' — it means your brain is doing what it was designed to do, just too much and too often."
"I think there's something wrong with my heart — the palpitations feel so real."
"Your palpitations are absolutely real — I'm not suggesting you're imagining them. What I can tell you is that your heart examination and ECG are completely normal, and palpitations are one of the most common physical symptoms of anxiety. Anxiety directly activates your heart's accelerator — it's not a coincidence that your palpitations happen when you're stressed or worried. Once we treat the anxiety, most people find those palpitations disappear entirely."
"I just need to get a grip — I can't understand why I can't just stop worrying."
"I hear that a lot, and I want to gently push back on it. Anxiety isn't a failure of willpower — it's a biological process that happens below the level of conscious control. Telling yourself to stop worrying is like telling your heart to slow down by choosing to be calm. We have very effective treatments that work with the biology rather than against it. You haven't been able to 'just stop' because it's not that kind of problem."
Generalised Anxiety Disorder (GAD) — Excessive, uncontrollable, multi-domain worry ≥6 months + ≥3 associated symptoms + significant impairment. GAD-7 measures severity — it does not make the diagnosis. NICE CG113 / DSM-5 criteria.
Adjustment disorder with anxiety — Anxiety <6 months, clear precipitant, proportionate. Watchful waiting, psychoeducation, and social support often sufficient.
GAD with comorbid depression — PHQ-9 ≥10 alongside GAD-7 ≥10. SSRI addresses both; NHS Talking Therapies dual-pathway; close monitoring.
Panic Disorder
Discrete unexpected panic attacks + anticipatory worry about future attacks + avoidance. Interoceptive exposure CBT; SSRIs effective.
Social Anxiety Disorder
Anxiety specifically in social or performance situations; fear of negative evaluation. Distinct CBT pathway; SSRI effective.
Health Anxiety (Illness Anxiety Disorder)
Excessive worry about having a serious illness despite negative investigations; reassurance-seeking. Avoid over-investigation; CBT addresses threat appraisal.
Hyperthyroidism
TSH <0.1 + free T4 elevated + anxiety + palpitations + weight loss → urgent endocrinology + propranolol + carbimazole.
PTSD
Trauma history + hypervigilance + intrusive symptoms + avoidance → EMDR or trauma-focused CBT; ask directly about re-experiencing, avoidance and hyperarousal (PC-PTSD-5 is case-finding only).
Phaeochromocytoma / Cardiac Arrhythmia
Episodic hypertension + diaphoresis + palpitations / ECG arrhythmia → urgent investigation; do not attribute to anxiety without excluding these.
- Saying "it's just anxiety" without an explanation — dismissive and clinically inadequate
- Not distinguishing GAD from panic disorder, social anxiety, or PTSD
- Not connecting physical symptoms (palpitations, headaches) to the anxiety diagnosis explicitly
- Failing to address the patient's specific disease model (the heart fear must be addressed by name)
- Referring to NHS Talking Therapies and implying no further GP involvement — patients feel abandoned
- Not explaining what NHS Talking Therapies is — many patients assume it means seeing a psychiatrist
- Prescribing pregabalin when SSRIs/SNRIs can be tolerated, or without a misuse risk assessment
- Not referring a pregnant patient with severe or complex anxiety to the perinatal mental health team
Validate — name their expectation
The most common expectation in GAD is "something to calm me down" — often meaning benzodiazepines. This is entirely understandable and must be validated before it can be redirected. Immediately saying "I won't prescribe diazepam because it's addictive" shuts the conversation and damages the therapeutic relationship.
"I completely understand why you'd want something that takes the edge off quickly — when you're this anxious, you just want relief and you want it now. That makes complete sense."Explain — share your clinical reasoning
Explain why the short-term appealing option (benzodiazepines) is less helpful than the longer-term approach, and why the evidence-based treatments (CBT + SSRI) work better. Use the brain alarm system analogy to explain the mechanism.
"The difficulty with something like diazepam is that it turns down the alarm temporarily, but it doesn't fix the reason it's overtuned — and over time, the alarm can actually become more sensitive. What CBT and the right medication do is retune the alarm, which is a more lasting solution."Negotiate — offer something today
Never leave the patient with nothing. If SSRI is appropriate, start it today. Make the NHS Talking Therapies referral today. Provide written self-help resources. If a very short-term anxiolytic is truly necessary, a strictly time-limited benzodiazepine course (fixed quantity and end date, usually no longer than 2–4 weeks) is negotiable — with clear agreement about limits.
"What I can offer you today: a start on the medication with the best evidence for this kind of anxiety — most people notice a difference within 2–4 weeks; a referral to NHS Talking Therapies for the talking therapy that works best for GAD; and some written resources for the meantime. Let's also agree a follow-up in 2 weeks."Caffeine blocks adenosine receptors (the brain's natural calming system), increases cortisol, activates the HPA axis, and directly triggers anxiety, palpitations, and insomnia. Even moderate intake (2–3 cups/day) significantly worsens GAD symptoms via adenosine antagonism and catecholamine release.
Quantify intake across all sources: coffee, tea, cola, energy drinks, chocolate. Switch to decaffeinated versions after noon. Reduce gradually over 1–2 weeks to avoid withdrawal headaches. There is no rigid universal threshold — reduce where caffeine clearly aggravates symptoms.
Regular aerobic exercise reduces amygdala reactivity, increases GABA and endorphin levels, normalises HPA axis cortisol, and improves sleep quality. A single session of moderate exercise produces acute anxiolytic effects lasting 4–6 hours.
Brisk walking, swimming, cycling, or running 30 minutes, 5 days/week. Social exercise (classes, sport) provides additional social support benefit. Morning exercise improves sleep quality. Yoga and Tai Chi have specific evidence for anxiety reduction via parasympathetic activation.
Sleep deprivation amplifies amygdala reactivity to threat and reduces prefrontal cortex regulation of the fear response — making anxiety both more intense and harder to control. Anxiety and poor sleep form a bidirectional vicious cycle.
Fixed morning wake time (most important single sleep behaviour change); no screens 1 hour before bed; cool, dark, quiet room; no alcohol (disrupts REM sleep); if lying awake worrying for >20 minutes, get up and do a quiet activity. CBT-I (CBT for insomnia) when sleep is a primary problem.
Alcohol provides initial anxiolysis via GABA enhancement but causes significant rebound anxiety 4–6 hours later as GABA receptors downregulate. Regular evening drinking creates a morning anxiety cycle. Many patients with GAD use alcohol to self-medicate — this creates a maintenance cycle preventing SSRI effectiveness.
AUDIT-C at every anxiety consultation; brief intervention (FRAMES); advise alcohol-free days; reduce particularly before bed; connect alcohol reduction to anxiety improvement as a motivational frame.
Mindfulness deactivates the default mode network (the brain's rumination circuit), reduces amygdala reactivity, and increases prefrontal regulation of the fear response. MBSR has RCT evidence for GAD with effect sizes comparable to active treatment.
Apps: Headspace (GAD-specific programme), Calm, Woebot (CBT-based chatbot). MBSR 8-week programme available via NHS Talking Therapies and NHS online. Progressive muscle relaxation effective for physical tension. Diaphragmatic breathing (4-7-8 technique or box breathing) for acute anxiety management.
Social isolation is both a consequence of GAD avoidance and an independent maintaining factor. Meaningful social contact is the most powerful natural anxiolytic. Group CBT for anxiety provides both treatment and social exposure simultaneously.
Social prescribing link worker referral; community groups (MIND, anxiety support groups, exercise classes); group CBT via NHS Talking Therapies; volunteering; befriending services. Encourage gradual re-engagement with avoided social activities as behavioural activation.
Sertraline 50mg OD (consider 25mg where activation or panic is likely) — take with food; titrate per SPC if inadequate response; maximum 200mg; may be off-label for GAD — check the SPC and document consent; judge after an adequate, disorder-appropriate trial at a therapeutic dose.
- Preferred over other SSRIs: lowest drug interaction profile and best cardiac safety
- Always warn about initial anxiety worsening (first 1–2 weeks) — common and temporary
- Onset of anxiolytic effect: 2–4 weeks; full effect at 6–12 weeks
- Continue for minimum 12 months after remission — reduces relapse by 50%
Venlafaxine XR 75mg OD (escalate to 150mg if needed) or Duloxetine 30mg OD (escalate to 60–120mg). Used after sertraline (and usually an alternative SSRI) is ineffective or not tolerated — NICE CG113.
- Venlafaxine: preferred if pain comorbidity; warn about discontinuation syndrome
- Duloxetine: good evidence in GAD + comorbid pain (fibromyalgia, neuropathic pain)
- Blood pressure monitoring with venlafaxine at all doses (before starting and regularly during treatment; the rise is dose-related): noradrenergic effect raises BP
Pregabalin 75mg BD (escalate to 150–300mg BD). NICE CG113: consider pregabalin if the person cannot tolerate SSRIs or SNRIs. Many local formularies ask for specialist advice first because of misuse risk.
- Controlled drug (Schedule 3) — monitor for misuse; urine drug screen before initiation
- Faster onset than SSRIs (days vs. weeks) — but limited to short-term use
- Risk of dependence and misuse — do not prescribe to patients with substance use disorder without specialist input
- Not recommended for routine GAD management — NICE CG113
- Acceptable (fixed end date, usually ≤2–4 weeks): acute severe distress during SSRI initiation while awaiting onset; crisis situation
- Diazepam 2–5mg TDS PRN — if prescribed, document indication clearly, fixed end date, and plan for SSRI to replace
- Never in older adults — falls, cognitive impairment, paradoxical agitation
- Benzodiazepine dependence: individualised gradual taper per local/UK withdrawal guidance (diazepam substitution not right for everyone); involve community drug and alcohol team
- Buspirone: anxiolytic without dependence; slow onset (2–4 weeks); useful if benzodiazepine-dependent; non-addictive
- Hydroxyzine: rapid onset antihistamine anxiolytic; non-addictive; drowsiness is main side effect; max 100 mg daily, 50 mg in older people (MHRA 2015 — QT risk)
- Propranolol 10–40mg PRN: reduces peripheral anxiety symptoms (palpitations, tremor); no central anxiolytic effect; useful for performance anxiety; avoid in asthma/COPD
- Mirtazapine: useful in GAD with comorbid insomnia and poor appetite; sedating; appetite-stimulating; not first-line for GAD
- Moderate-severe GAD (GAD-7 ≥10) — first treatment
- Cardiac disease (IHD, arrhythmia, heart failure)
- Comorbid depression (PHQ-9 ≥10)
- Comorbid chronic pain (fibromyalgia, neuropathy)
- Benzodiazepine dependence — needs managed withdrawal
- Failed ≥2 adequate SSRI trials
- Pregnant or breastfeeding
- Situational / performance anxiety only
- Comorbid insomnia and poor appetite
"This tablet takes 2–4 weeks to start working on the anxiety — in the first week or two you might feel slightly more anxious, which is normal and temporary. It doesn't change who you are; it reduces the biological over-activation. I want to see you in 2 weeks, and please contact us immediately if your thoughts become very dark."
The early review after SSRI initiation (within 1 week if under 30 or at higher risk, otherwise 1–2 weeks) is NICE CG113. SSRIs briefly increase energy before lifting mood — this is the highest suicide risk window. Missing this review in a patient with comorbid depression is a clinical governance failure and an SCA Task deduction.
"This is a different version of the same class of medication — it works in a very similar way but sometimes suits different people better. The same rules apply: 2–4 weeks before you notice significant improvement, and I'll see you in 2 weeks to check how you're getting on."
Escitalopram has a specific licensed indication for GAD — making it, alongside sertraline and venlafaxine, one of the most evidence-supported pharmacological options. Fluoxetine is NOT a first-line choice for GAD (poor evidence base; long half-life; drug interactions).
"Take this with food — nausea can be quite noticeable in the first couple of weeks. One very important thing: never stop this medication suddenly. If you want to stop, even after a course of treatment, we need to do it gradually — stopping abruptly can cause very unpleasant symptoms. Always come and talk to me first."
Venlafaxine discontinuation syndrome is the most important counselling point — it can be severe and distressing. Patients frequently stop suddenly when they feel better; the resulting syndrome is often misattributed to the anxiety returning. This counselling point is an SCA Task mark.
"This medication works more quickly than the SSRI — you should notice a difference within a few days. The most common side effect is dizziness and feeling a bit 'spaced out' at first — that usually improves after a week or two. Don't drive until you know how it affects you. Because this is a controlled drug, we'll prescribe it in smaller quantities and review it regularly."
Prescribing pregabalin first-line for GAD, before SSRIs and SNRIs have been tried and found intolerable, is outside NICE CG113 guidance. Pregabalin is a Schedule 3 controlled drug — document clinical justification at every prescription.
"Take this tablet about 30–45 minutes before the situation you find difficult — it won't stop you feeling anxious mentally, but it will stop your heart racing and your hands shaking, which often makes the whole experience feel much more manageable. It's not a long-term solution on its own, but it can be really useful while we work on the underlying anxiety with the other treatments."
Propranolol reduces peripheral anxiety symptoms but has no central anxiolytic effect — it does not treat the worry, only the physical manifestation. Prescribing it without also addressing the core anxiety (SSRI + CBT) is incomplete management.
"I'm prescribing this for a maximum of 2 weeks — I want to be very clear about that. It will help with the acute distress while we wait for the sertraline to work. Longer than 2 weeks, and there's a real risk of becoming dependent, which would create a new problem on top of the anxiety. We'll review at 2 weeks and this will be the last prescription unless there are exceptional circumstances."
Never prescribe diazepam for chronic GAD without a clear plan for cessation. If a patient requests "diazepam like before," acknowledge the request, explain the dependence risk, offer SSRI + CBT as the superior alternative, and if a short course is genuinely needed, prescribe with a fixed 2-week end date and document the clinical justification clearly.
Occupational Impact
GAD significantly impairs concentration, decision-making, and the ability to tolerate work uncertainty. Presenteeism (attending work while severely impaired) is more common than absenteeism in GAD.
Fit notes should be considered if severe GAD prevents effective work — "may be fit for work with adaptations" (flexible hours, reduced targets, remote working) is often more appropriate than full sick leave.
Employee Assistance Programmes (EAPs) often provide immediate CBT access — signpost proactively.
"How much is this anxiety affecting your work? Is it affecting your ability to concentrate or make decisions, or are there days when you can barely function?"Driving and DVLA
Moderate-severe GAD can impair driving via poor concentration, hypervigilance, and avoidance of motorway or night driving. Patients should self-assess fitness to drive.
Benzodiazepines and pregabalin impair driving — patients must be counselled not to drive until their response to the medication is known.
DVLA notification is not routinely required for GAD — but if the patient believes their anxiety significantly impairs their driving, they should contact DVLA or their insurer.
"Some of the medications we're considering can affect your ability to drive safely, particularly when you first start them — please don't drive until you know how they affect you."Relationships and Intimacy
GAD strains relationships through irritability, reassurance-seeking, avoidance, and emotional withdrawal. Partners often become inadvertent enablers — providing excessive reassurance that maintains the anxiety cycle.
Sexual dysfunction is common in GAD itself and worsened by SSRIs (delayed ejaculation, anorgasmia, reduced desire).
Couples or family therapy may be beneficial alongside individual CBT — relational dynamics maintaining anxiety need to be addressed.
"Has the anxiety affected your relationships — with your partner, your family? Do you find yourself needing a lot of reassurance from the people close to you?"Identity and Self-Concept
Long-standing GAD often becomes entwined with identity — "I've always been a worrier" or "I'm just an anxious person." This self-labelling creates a barrier to treatment: patients may feel treating the anxiety is changing who they fundamentally are.
Reframing — "this isn't who you are, it's a treatable condition that's been happening to you" — is a powerful therapeutic intervention that shifts the relationship between patient and anxiety.
Recovery involves not just symptom reduction but identity reconstruction — supported by CBT and peer support.
"Some people who've been anxious for a long time start to feel like that's just 'who they are.' I want to gently offer a different perspective — this is something that's been happening to you, not something that defines you."Social Life and Avoidance
Avoidance progressively restricts the patient's world — social events declined, activities abandoned, relationships withdrawn from. Each avoidance reduces anxiety short-term but maintains it long-term by preventing habituation.
Social prescribing — gentle re-engagement with community, peer groups, and activities — is both a treatment for avoidance and a source of social support that reduces anxiety biologically.
Group CBT for anxiety provides both the therapeutic intervention and the social exposure simultaneously.
"Has the anxiety caused you to start pulling back from things you used to do or people you used to see? Sometimes anxiety quietly shrinks our world over time without us fully noticing."Benefits, Disability, and Legal Rights
Moderate-severe GAD that substantially affects normal daily activities for 12 months constitutes a disability under the Equality Act 2010 — employers must make reasonable adjustments.
For patients unable to work: Statutory Sick Pay, ESA, and PIP may be applicable. GP letters of support may be needed — provide factual, functional letters.
Social prescribing link workers can navigate the benefits system alongside clinical treatment.
"If the anxiety is making it very difficult to work, there may be things you're entitled to — both from your employer in terms of adjustments, and potentially financially. I can provide a supporting letter if that would help."1–2 weeks — Mandatory SSRI review
If SSRI started: mandatory per NICE CG113 — within 1 week if under 30 or at increased risk (then weekly for the first month), otherwise 1–2 weeks. Assess: tolerability (nausea, agitation settling?), suicide risk in comorbid depression (PHQ-9 item 9), early signs of response. Review NHS Talking Therapies referral status. Adjust management if not tolerated.
4–6 weeks — Treatment response assessment
GAD-7 score (compare with baseline — target ≥50% reduction). PHQ-9 if depression. SSRI dose adequacy: if GAD-7 has not improved, increase dose (50→100mg sertraline). Side effects: particularly sexual dysfunction or emotional blunting — these may not be volunteered.
3 months — CBT engagement and medication threshold
If no response to SSRI at 12 weeks at therapeutic dose → switch SSRI or switch class (SSRI → SNRI). CBT progress: has the patient started NHS Talking Therapies? Review technique and identify barriers. If GAD-7 improved but not to remission: continue current treatment; monthly review.
6 months — Remission assessment and continuation planning
GAD-7 <5 = remission. If remission: plan minimum 12 months continuation of SSRI (reduces relapse by 50%). Review residual avoidance. If not in remission after 2 SSRIs: consider SNRI, then pregabalin only if SSRIs/SNRIs cannot be tolerated; CMHT referral if refractory.
Annual — Relapse prevention and medication review
Annual review: GAD-7 and PHQ-9; medication continuation or planned tapering if stable for ≥12 months; discuss relapse warning signs; review self-management plan; social prescribing update; lifestyle review (caffeine, alcohol, exercise, sleep).
Memory rule — GAD Monitoring: SCALE
Score (GAD-7 at every contact — target ≥50% reduction from baseline) · Comorbid depression (PHQ-9 — mandatory at every contact; item 9 suicide risk) · Adherence and side effects (sexual dysfunction, blunting — ask directly; venlafaxine BP monitoring) · Lifestyle (caffeine, alcohol, exercise, sleep — review at every contact) · Escalation threshold (no response at 12 weeks therapeutic dose → switch; 2 SSRI failures → CMHT referral)

Who you are
Sarah Chen, 36 years old, secondary school teacher. Has been experiencing persistent, uncontrollable worry for about 9 months — about her job performance, her children's health, finances, relationships, and the state of the world. Wakes at 3 am with racing thoughts most nights. Has started avoiding motorway driving and declining social invitations. A&E twice with palpitations and chest tightness — both times cardiac causes were excluded. Feels embarrassed and believes she "should be able to control it." Drinks 4–5 cups of coffee per day and about 12–14 units of alcohol per week (wine in the evenings to "unwind"). PHQ-9 score: 9 (mild depression but below active treatment threshold). GAD-7 score when administered: 14 (moderate-severe).
Hidden agenda
Sarah is convinced something is wrong with her heart — she does not believe the A&E discharge was thorough enough. She secretly hopes for a cardiology referral, or at least a repeat ECG. The real fear underneath is not just cardiac disease — she worries she is "going mad," that she will lose control, and that her family will see her as unable to cope. She will not disclose this fear unless directly asked. She is also hoping for diazepam — a friend takes it and "it works immediately." She feels desperate enough to ask despite having heard it can be addictive.
Symptoms if asked directly
- Worry: multi-domain; cannot stop once it starts; "a radio that won't turn off"
- Duration: 9 months without a significant break
- Physical: palpitations, chest tightness, daily tension headaches, muscle tension, fatigue
- Sleep: wakes at 3 am approximately 4–5 nights/week; lies awake 1–2 hours with racing thoughts
- GAD-7 score: 14 (moderate-severe); PHQ-9 score: 9 (sub-threshold depression)
- No current suicidal ideation — PHQ-9 item 9 = 0
- Avoidance: motorway driving, large social gatherings, has stopped yoga class
- No weight loss, no heat intolerance, no thyroid symptoms
- Caffeine: 4–5 cups filter coffee/day plus 2 diet colas; no reduction attempted
- Alcohol: 12–14 units/week; mostly wine after 9 pm "to help me wind down"
Lifestyle + bonus details
- Teaching very stressful — feels on verge of burnout; OFSTED inspection pending
- Two children (ages 6 and 9) — worries excessively about them
- Has never had CBT; heard of "talking therapy" but fears it won't work for her
- Bonus detail (if doctor asks about caffeine): admits she drinks a lot of coffee but genuinely did not know it could worsen anxiety — very receptive to this information
- Bonus detail (if doctor asks about evening alcohol): drinks "to relax" and has not connected it to the 3 am wakening — this is a significant therapeutic insight if the doctor makes the connection for her
Resolution: Sarah will accept the plan if the doctor: (1) directly acknowledges and addresses her cardiac fear by name — not obliquely; (2) explains the biological basis of anxiety and explicitly links her palpitations and chest tightness to the anxiety mechanism; (3) acknowledges the diazepam request empathetically before redirecting, rather than immediately refusing; (4) offers sertraline with a clear explanation including the initial worsening; (5) refers to NHS Talking Therapies and explains what CBT involves; (6) makes the connection between her caffeine intake and her anxiety symptoms — she genuinely does not know this link; (7) explores the evening alcohol as a 3 am wakefulness driver; (8) arranges a named 2-week review appointment; (9) gives her permission to return sooner if things escalate.

- Severe self-neglect / unable to care for dependants → same-day psychiatric
- PHQ-9 ≥15 with ideation (no plan) → CRHT contact same day
- New anxiety in >50 without precipitant → urgent bloods + ECG
- Palpitations + syncope → ECG same day + Holter
- Benzodiazepine dependence needing withdrawal → weekly GP review
- GAD + severe depression → SSRI within days; 2-week review
- GAD-7 5–9 (mild) → Step 2: self-help + NHS Talking Therapies low-intensity
- Marked symptoms/impairment (GAD-7 typically ≥10) → Step 3: high-intensity CBT or SSRI by preference, or both
