What is anxiety? Understanding anxiety disorders
Normal anxiety is a useful response to danger. It becomes an anxiety disorder when it is persistent, disproportionate and disrupts your daily life. This guide helps you tell the two apart, identify which of the 6 official forms you're living with, and know when to seek help.

Anxiety becomes an anxiety disorder when it lasts more than 6 months, is disproportionate to the real threat, and impairs your daily functioning (DSM-5). 15% of adults are affected each year, 21% at least once in their lifetime (Inserm, HAS 2026). There are 6 official forms — the GAD-7 test gives a free, confidential first overview.

Anxiety disorders are the most common mental-health disorders in France. They are twice as frequent in women, often begin in adolescence, and respond well to CBT and SSRIs (Inserm, HAS).
- 21% lifetime prevalence — you are not alone (Inserm)
- 6 official forms: GAD, panic, social anxiety, agoraphobia, specific phobias, separation anxiety (DSM-5)
- CBT + SSRIs = first-line treatment (HAS)
Normal anxiety or anxiety disorder: where is the line?
Feeling anxious before an interview, a medical appointment, or an exam is normal and useful — it's an alarm signal that mobilises your body to act (Inserm). The problem starts when this response triggers out of context, lasts too long, or becomes disproportionate to the situation.
The 3 criteria that tip you into a disorder
The DSM-5 sets three precise thresholds. Duration: anxiety persists for at least 6 months. Intensity: it is disproportionate to the objective danger. Impact: it impairs your social, professional or personal functioning. When all three are met, we speak of an anxiety disorder — and there are effective treatments.
Who is affected?
Anxiety disorders are the most common mental-health disorders: 15% of adults each year, 21% over a lifetime (HAS, cited by Inserm). They are twice as frequent in women, with a treatment peak between 15 and 19 years (BEH). In 70 to 80% of cases, a depressive episode joins sooner or later — one more reason to act early.
Where does it come from?
The origin is multifactorial: genetic vulnerability (serotonin transporter gene), temperament, personal history, traumatic events, substance use (Inserm). No single gene causes anxiety — it's an interaction between biology, environment and learning. It is never 'in your head' in a pejorative sense: the amygdala and insular cortex circuits are measurably hyperactive in affected people (imaging).
- 3 DSM-5 criteria: duration ≥ 6 months, disproportionate intensity, daily impact
- Prevalence: 15% yearly, 21% lifetime, 2× more in women (Inserm/HAS)
- Origin: genetic + environment + history, hyperactive amygdala/insula circuits
- Good news: CBT and SSRIs work — most people improve
The 6 anxiety disorders recognised by the DSM-5
You don't necessarily recognise yourself in 'anxiety' broadly — often, it's one specific form that matches what you're living with. Here are the 6 official forms, each with its specific signs (Inserm, DSM-5).
Generalized anxiety disorder (GAD)
Permanent, excessive worry about everyday matters (work, family, health, money) — without being able to switch off. You anticipate the worst, you ruminate, and your body stays tense even at rest. Prevalence: 2.1% per year, 6% lifetime. It's the most common anxiety disorder in adults.
Au quotidien
- • You worry more than 6 hours a day without being able to stop
- • Fragmented sleep, muscle tension, chronic fatigue
- • Concentration difficulty: your mind jumps from problem to problem
Panic disorder and panic attacks
Intense, brief (20-30 min), unpredictable episodes with a feeling of impending death or loss of control. Physical symptoms are so strong (palpitations, chest tightness) that they often lead to ER visits. Prevalence: 1.2% per year, 3% lifetime. Many people then develop a fear of fear — this is anticipatory anxiety.
Au quotidien
- • Palpitations, sweating, trembling, shortness of breath, choking sensation
- • Feeling like you're 'going crazy' or dying on the spot
- • You avoid places where you've previously had an attack
Social anxiety disorder
Intense fear of others' gaze and negative judgment. Speaking up in a meeting, eating in public, meeting strangers — everything is filtered through the same question: 'they're going to judge me'. Prevalence: 1.7% per year, 4.7% lifetime. Often begins between 11 and 15. The Clark & Wells model (1995) explains why it self-maintains through self-focused attention and safety behaviours (avoiding eye contact, preparing scripts).
Au quotidien
- • You blush, sweat, tremble as soon as you're watched
- • You ruminate afterwards ('I said something stupid')
- • You avoid parties, public speaking, work lunches
Agoraphobia
Fear of places from which it would be hard to escape: public transport, crowds, queues, large open spaces, bridges. Often secondary to panic disorder: you flee places where an attack would be embarrassing. Prevalence: 0.6% per year, 1.8% lifetime. Untreated, it can confine a person at home.
Au quotidien
- • You haven't taken the metro in months
- • You'd rather walk 2 km than take an elevator
- • You ask to be accompanied in supermarkets
Specific phobias
Irrational, intense fear toward a specific object or situation: animals (spiders, dogs), heights, injections, blood, flying, driving. The fear is disproportionate but you know it's logically excessive — you just can't control it. Prevalence: 4.7% per year, 11.6% lifetime — the most common form (Inserm). CBT with graded exposure is very effective.
Au quotidien
- • Sight of blood / needle: vagal syncope, you almost faint
- • You've refused to fly for X years
- • A spider in the room makes you leave the house
Separation anxiety (adult)
Persistent, disproportionate fear of being separated from the people who matter most to you. Often begins in childhood and can persist into adulthood (recognised in the DSM-5 since 2013). You struggle to sleep alone, to travel without the key person, and have recurring nightmares about losing them.
Au quotidien
- • You call your partner several times a day fearing something happens to them
- • You haven't been able to sleep alone for years
- • Solo travel puts you in a state of constant worry

Normal anxiety, stress, anxiety disorder, panic attack: the differences
These four states are often confused, yet only an anxiety disorder justifies a specific treatment. If you also feel persistent sadness, check our depression guide — both disorders are associated in 70 to 80% of cases (Inserm).
| Distinguishing sign | Typical duration | Life impact | |
|---|---|---|---|
| Normal anxiety | Proportionate to a real threat, action-driving | Minutes to hours | Helps you act, disappears afterwards |
| Passing stress | Tied to an identifiable event (exam, move) | Days to weeks | Manageable, fades with adaptation |
| Anxiety disorder | Disproportionate, no clear trigger, intrusive | ≥ 6 months (DSM-5) | Impairs work, relationships, sleep |
| Panic attack | Acute episode with intense physical symptoms | 20-30 minutes per episode | Highly disabling during the attack, avoidance after |
When at least one of '≥ 6 months', 'disproportionate', 'impairs daily life' is met, consult. The GAD-7 (cutoff ≥ 10) helps decide if a consultation is relevant.
Panic attack and physical symptoms: what's happening in the body?
Anxiety never stays in your head. When your amygdala detects danger (real or perceived), it triggers the stress cascade: adrenaline, cortisol, sympathetic system. Your body prepares to fight or flee. If the danger is real, it's vital. If your brain gets the context wrong, you live the same symptoms without real danger — that's the panic attack.
7 typical physical symptoms
The symptoms you feel are not imagined — they are measurable. Tachycardia (racing heart), hyperventilation (rapid, shallow breathing), muscle tension (shoulders, neck, jaw), nausea or stomach knot (gut-brain axis), trembling (hands, legs), cold sweats (palms, forehead), dizziness and derealisation. In panic disorder, some fear a heart attack — this is extremely rare: anxiety does not cause a myocardial infarction.
Panic attack: the 5-4-3-2-1 technique to come back to calm
When an attack starts, the limbic brain takes over the cortex. To break the cycle, the 5-4-3-2-1 sensory grounding protocol (CBT-validated): name 5 things you see, 4 things you touch, 3 sounds you hear, 2 smells, 1 taste. This brings the cortex back online and redirects attention to the present. Combined with slow breathing (4 sec inhale, 6 sec exhale), the attack passes in 15-20 minutes. If you feel chronic anxiety at work, our burnout guide completes the picture.

5 myths about anxiety
False. Brain imaging shows that the amygdala and insular cortex are hyperactive in anxious people (Inserm). Physical symptoms are real and measurable. Telling an anxious person to 'snap out of it' is like telling an asthmatic to 'stop being asthmatic'.
Nuance. The bag can help in case of pure hyperventilation (respiratory alkalosis) — but it's dangerous if the cause is cardiac, asthmatic, or a pulmonary embolism. Current guidelines favour slow controlled breathing (4/6) or the 5-4-3-2-1, risk-free.
False. Avoidance is the main maintenance factor of anxiety disorders (Clark & Wells, 1995). Every avoidance strengthens the fear and shrinks your radius. The first-line treatment (CBT) instead works through graded, controlled exposure to the trigger.
Nuance. Benzodiazepines (Xanax, Lexomil) do carry a dependence risk after a few weeks — they are therefore prescribed short-term only (HAS). SSRIs (antidepressants used as anxiolytics) don't cause dependence and are the long-term reference treatment.
False. The symptoms (palpitations, chest tightness) resemble a myocardial infarction, but a panic attack does not cause a heart attack in a cardiovascularly healthy person. When in doubt, call 15 (France) or your local emergency number — always the right call.

Think you have an anxiety disorder? 4 concrete steps
An accessible path, at your pace — from recognition to consultation.
Recognise and name what you're living
For 2 weeks, log every anxiety episode: trigger, intensity (0-10), duration, physical symptoms. This journal defuses rumination and becomes a valuable asset in consultation. If you spot a pattern (morning, work, Sunday night), you'll already have 50% of the diagnosis.
Take the GAD-7 test (10 minutes)
The GAD-7 (Spitzer, Kroenke, Williams & Löwe, 2006) is the reference screening tool used in general practice. 7 questions, score 0-21. Cutoff 10 = moderate anxiety, consult. Our test reproduces the GAD-7 in full — immediate result, confidential.
Improve your lifestyle (measurable effect within 4 weeks)
Regular sleep (7-9h, fixed bedtime), physical activity (30 min 3×/week lowers anxiety as much as a mild anxiolytic per meta-analyses), reduced caffeine (< 200 mg/day), limited alcohol. These changes don't cure an established disorder but significantly lower the anxiety baseline.
Consult a professional (CBT therapist or doctor)
First-line treatment per HAS: CBT (cognitive-behavioural therapy) — typically 12 to 20 sessions, partially reimbursed via Mon Soutien Psy. If the impact is major, an SSRI (antidepressant used as anxiolytic) can be added by a doctor. Benzodiazepine-type anxiolytics are reserved for short-term use.
Questions frequentes
CBT with graded exposure is the reference treatment (HAS). In parallel: identify your safety behaviours (avoiding eye contact, scripting speech) and aim to reduce them progressively. The Clark & Wells model (1995) shows these behaviours maintain the disorder more than they relieve it.
Use the 5-4-3-2-1 sensory grounding protocol (5 things seen, 4 touched, 3 heard, 2 smelled, 1 tasted) combined with slow breathing (4 sec inhale, 6 sec exhale). The attack typically fades in 15-20 minutes. Avoid breathing into a bag if you're not sure of the cause.
Anxiety is turned toward the future and danger ('what if it happens?'), depression toward the present and loss ('nothing makes sense'). Both combine in 70 to 80% of cases (Inserm) — if you suspect an associated depression, see our depression guide. A professional makes the differential diagnosis.
Yes, very often. CBT is the first-line treatment per HAS — its efficacy is equivalent to SSRIs, with benefits that last longer after stopping. Regular physical activity and mindfulness techniques also have measurable effects on mild-to-moderate anxiety.
As soon as one of these 3 signals is present: your anxiety has lasted more than 6 months, it's disproportionate to the real threat, or it impairs your sleep/work/relationships. A GAD-7 score ≥ 10 is also a clear indication. Don't wait for it to worsen: the sooner you consult, the shorter the treatment.
Stress is the response to an identifiable event (exam, move) — it disappears with the event. Anxiety is anticipatory, floating, sometimes without a clear cause. When it persists ≥ 6 months and impairs your life, we speak of an anxiety disorder (DSM-5). Chronic stress can, however, trigger an anxiety disorder in vulnerable people.
