Agoraphobie

Qu'est-ce que l'agoraphobie ?

Agoraphobia is a type of anxiety disorder. Many people think that agoraphobia means a fear of public places and open spaces, resulting in sufferers being unable to leave their homes. However, that is just part of it.

If you have agoraphobia you tend to have intense and excessive fear or anxiety about a range of situations from which escape might be difficult or where help might not be available. So, for example, you may have a fear of:

• Being in shops, crowds and public places.

• Travelling in trains, buses, or planes.

• Being on a bridge.

• Being in enclosed spaces, like a lift.

• Being in a cinema, restaurant, etc, where there is no easy exit.

• Being outside the home on your own.

Agoraphobia is usually a lifelong problem unless treated.

The exact cause of agoraphobia isn't known, but is likely to be a combination of genes, imbalances in certain brain chemicals, and psychological risk factors such as childhood trauma, stressful events, drug or alcohol use, and having other mental health conditions.

It typically starts in late adolescence and before the age of 35 years. Twice as many women are diagnosed with agoraphobia compared to men.

Panic disorder and agoraphobia

Many, but not all, people with a separate condition called panic disorder can develop agoraphobia. Briefly, in panic disorder, people have panic attacks that occur suddenly, often without warning. A panic attack is like a sudden and severe attack of anxiety and extreme fear.

See the separate leaflet called Panic Attacks and Panic Disorder for more details.

Agoraphobia can also be triggered if someone has a panic attack in a specific situation, or if they have a specific phobia (for example, getting infections from being in crowded places).

Physical symptoms

Physical agoraphobia symptoms usually present much like attaques de panique. They can happen when a person is in the situation or when they anticipate it, and include:

• Rythme cardiaque rapide.

• Rapid breathing (hyperventilating).

• Des nausées.

• Sweating and feeling hot.

• Douleur thoracique.

• Trembling.

• Vertiges.

• Se sentir faible.

• Diarrhée.

• Ringing in the ears (acouphènes).

Cognitive symptoms

With agoraphobia, you are constantly fearful or anxious because of an underlying fear of specific bad outcomes. These are called cognitive symptoms and the feared bad outcomes include:

• Having a panic attack that leads to embarrassment or humiliation.

• Having a panic attack that leads to death or injury.

• Losing your sanity.

• Losing control in public.

• Being unable to function without the help of someone else.

Symptômes comportementaux

People with agoraphobia develop avoidance behaviours in response to their fear and anxiety. These might include:

• Avoiding situations that may trigger agoraphobia, such as crowded places or public transportation.

• Not leaving the house for long periods of time.

• Needing to be accompanied by someone everywhere they go.

• Avoiding being too far from home.

The severity of agoraphobia can vary greatly. Some people with agoraphobia can cope quite well outside their home by sticking to familiar areas and routines.

Some people with agoraphobia can go out from their home and travel on buses, trains, etc, without becoming anxious if they go with a friend or family member.

There may be times when they have good spells where they cope better than at other times. Many people with agoraphobia stay inside their homes for most or all of the time to avoid situations that may trigger anxiety.

Self-help techniques and lifestyle

There are a number of self-help guides available as booklets or online, which go through techniques such as breathing control, challenging unhelpful thoughts, and confronting the situations.

General lifestyle measures such as exercise, getting plenty of sleep, limiting caffeine and alcohol, and having a healthy diet can also help.

Thérapie cognitivo-comportementale (TCC)

TCC is a type of psychological therapy that helps you to change certain ways that you think, feel and behave. It is a useful treatment for various mental health problems, including phobias.

• Cognitive therapy is based on the idea that certain ways of thinking can trigger, or fuel, certain mental health problems such as anxiety, depression and phobias.

• Thérapie comportementale aims to change any behaviours which are harmful or not helpful. In agoraphobia, the therapist will usually help you to face up to feared situations, a little bit at a time. A first step may be to go for a very short walk from your home with the therapist who gives support and advice. Over time, a longer walk may be possible, then a walk to the shops, and then a trip on a bus, etc. The therapist teaches you how to control anxiety when you face up to the feared situations and places - for example, by using deep-breathing techniques. This technique of behavioural therapy is called exposure therapy - where you are exposed more and more to feared situations and you learn how to cope.

• Thérapie cognitivo-comportementale (TCC) is a mixture of the two where you may benefit from changing both your thoughts and your behaviours.

Other psychological therapies are also available.

Antidépresseurs

Antidépresseurs are commonly used to treat depression; however, they also help to reduce the symptoms of phobias, even if you are not depressed. They work by interfering with brain chemicals (neurotransmitters) - such as serotonin - which may be involved in causing anxiety symptoms.

• Antidepressants do not work straightaway. It takes 2-4 weeks before their effect builds up.

• Antidepressants are not tranquillisers and are not usually addictive.

• There are several types of antidepressants, each with various pros and cons. For example, they differ in their possible side-effects. However, Antidépresseurs inhibiteurs sélectifs de la recapture de la sérotonine (ISRS) (such as sertraline ou paroxétine) are the ones most commonly used for anxiety disorders.

Remarque: after first starting an antidepressant, in some people anxiety symptoms become worse for a few days before they start to improve.

A combination of CBT and an SSRI antidepressant may work better in some cases than either treatment alone. If these do not work, or symptoms are very severe, you can be referred to a specialist mental health service.

You should see a doctor if you think you may have agoraphobia, particularly if the symptoms are affecting your daily activities.

If you have been diagnosed with agoraphobia, you should see a doctor if your symptoms become worse or change in any way. You should also see a doctor if you start to have symptoms of panic attacks or depression that have not previously been assessed by a doctor.
