ANXIETY DISORDERS

When you are anxious you feel fearful and tense. In addition you may also have one or more unpleasant physical symptoms. For example: a fast heart rate, palpitations, feeling sick, shaking (tremor), sweating, dry mouth, chest pain, headaches, a 'knot in the stomach', fast breathing.

The physical symptoms are partly caused by the brain which sends lots of messages down nerves to various parts of the body when you are anxious. The nerve messages tend to make the heart, lungs, and other parts of the body 'work faster'. In addition, you release 'stress' hormones (such as adrenaline) into the bloodstream when you are anxious. These can also act on the heart, muscles and other parts of the body to cause symptoms.

Anxiety is normal in stressful situations, and can even be helpful. For example, most people will be anxious when threatened by an aggressive person, or before an important race. The burst of adrenaline and nerve impulses which we have in response to stressful situations can help us to 'fight or flight'.

Anxiety is 'abnormal' if it:

➙ Is out of proportion to the stressful situation, or

➙ Persists when a stressful situation has gone, or the stress is minor, or

➙ Appears for no apparent reason when there is no stressful situation.

What are Anxiety Disorders?

There are various conditions ('disorders') where anxiety is a main symptom. You may have an anxiety disorder if anxiety symptoms interfere with your normal day-to-day activities, or if worry about developing anxiety symptoms affects your life. About 1 in 20 people have an anxiety disorder at any one time. The following is a brief overview of the main anxiety disorders. Some people have features of more than one type of disorder.

Reactions to stress

Anxiety can be one of a number of symptoms as a reaction to stressful situations. There are three common types of 'reaction' disorders.

Acute reaction to stress (sometimes called 'acute stress reaction')

'Acute' means the symptoms develop quickly, over minutes or hours 'reacting' to the stressful event. Acute reactions to stress typically occur after an unexpected life crisis such as an accident, bereavement, family problem, bad news, etc. Sometimes symptoms occur before a known situation which is difficult. This is called situational anxiety. For example before: an exam, an important race, a concert performance, etc.

Symptoms usually settle fairly quickly, but can sometimes last for several days or weeks. Apart from anxiety, other symptoms include: low mood, irritability, emotional ups and downs, poor sleep, poor concentration, wanting to be alone.

Adjustment reaction :-

This is similar to the above, but symptoms develop days or weeks after a stressful situation as a reaction or 'adjustment' to the problem. For example, as a reaction to a divorce or house move. Symptoms are similar to acute reaction to stress but may include depression. The symptoms tend to improve over a few weeks or so.

Post traumatic stress disorder (PTSD) :-

This condition may follow a severe trauma such as a serious assault or life-threatening accident. Symptoms last at least one month, often much longer. Anxiety is only one symptom which may come and go.

The main symptoms of PTSD are:

➙ Recurring thoughts, memories, images, dreams, or 'flashbacks' of the trauma which are distressing.

➙ You try to avoid thoughts, feelings, conversations, places, people, activities or anything else which may trigger memories or thoughts of the trauma.

➙ Feeling emotionally 'numb' and feeling 'detached' from others. You may find it difficult to have loving feelings. Your outlook for the future is often pessimistic. You may lose interest in activities which you used to enjoy.

➙ Increased 'arousal' which you did not have before the trauma. This may include: difficulty sleeping, being irritable, difficulty concentrating, and increased 'vigilance'

Phobic Anxiety Disorders:-

A phobia is strong fear or dread of a thing or event. The fear is out of proportion to the reality of the situation. Coming near or in contact with the feared situation causes anxiety. Sometimes even thinking of the feared situation causes anxiety. Therefore, you end up avoiding the feared situation as much as possible, which can restrict your life and cause suffering.

Social Phobia :-

Social phobia (social anxiety disorder) is possibly the most common phobia. With social phobia you become very anxious about what other people may think of you, or how they may judge you. Therefore, you fear meeting people, or 'performing' in front of other people, especially strangers. You fear that you will act in an embarrassing way, and that other people will think that you are stupid, inadequate, weak, foolish, crazy, etc. You avoid such situations as much as possible. If you go to the feared situation you become very anxious and distressed.

Agoraphobia :-

This too is common. Many people think that agoraphobia means a fear of public places and open spaces. But this is just part of it. If you have agoraphobia you tend to have a number of fears of various places and situations.

So, for example, you may have a fear of:

➙ Entering shops, crowds, and public places.

➙ Traveling in trains, buses, or planes.

➙ Being on a bridge or in a lift.

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

But they all stem from one underlying fear. That is, a fear of being in a place where help will not be available or where you feel it may be difficult to escape to a safe place (usually to your home). When you are in a feared place you become very anxious and distressed, and have an intense desire to get out. To avoid this anxiety many people with agoraphobia stay inside their home for most or all of the time.

Other specific phobias :-

There are many other phobias of a specific thing or situation. For example: claustrophobia (fear of confined spaces or of being trapped); fear of certain animals; fear of injections; fear of vomiting; fear of being alone; fear of choking. But there are many more.

Other anxiety disorders :-

A. PANIC DISORDER

Panic disorder means that you get recurring panic attacks. A panic attack is a severe attack of anxiety and fear which occurs suddenly, often without warning, and for no apparent reason. The physical symptoms of anxiety during a panic attack can be severe and include: a thumping heart, trembling, feeling short of breath, chest pains, feeling faint, numbness, or pins and needles. Each panic attack usually lasts 5-10 minutes, but sometimes they come in 'waves' for up to two hours.

B. Generalized Anxiety Disorder (GAD)

If you have Generalized Anxiety Disorder (GAD) you have a lot of anxiety (feeling fearful, worried and tense) on most days. The condition persists long-term. Some of the physical symptoms of anxiety (detailed above) may come and go. Your anxiety tends to be about various stresses at home or work, often about quite minor things. Sometimes you do not know why you are anxious

In addition, you will usually have three or more of the following symptoms:

➙ Feeling restless, on edge, or 'keyed up' a lot of the time.

➙ Tiring easily.

➙ Difficulty concentrating and your mind 'goes blank' quite often.

➙ Being irritable a lot of the time.

➙ Muscle tension.

➙ Poor sleep (insomnia). Usually it is difficulty in getting off to sleep, or difficulty in staying asleep.

C. MIXED ANXIETY AND DEPRESSIVE DISORDER

In some people, anxiety can be a symptom when you have depression. Other symptoms of depression include: low mood, feelings of sadness, sleep problems, poor appetite, irritability, poor concentration, decreased sex drive, loss of energy, guilt feelings, headaches, aches, pains, and palpitations. Treatment tends to be mainly aimed at easing depression, and the anxiety symptoms often then ease too.

D. Obsessive Compulsive Disorder

Obsessive Compulsive Disorder (OCD) consists of recurring obsessions, compulsions, or both. Obsessions are recurring thoughts, images, or urges that cause you anxiety or disgust. Common obsessions are fears about dirt, contamination, germs, disasters, violence, etc. Compulsions are thoughts or actions that you feel you must do or repeat. Usually a compulsion is a response to ease the anxiety caused by an obsession. A common example is repeated hand washing in response to the obsessional fear about dirt or germs. Other examples of compulsions include: repeated cleaning, checking, counting, touching, hoarding of objects.

What is the treatment for anxiety disorders and phobias?

The main aim of treatment is to help you to reduce symptoms so that anxiety no longer affects your day-to-day life. The treatment options depend on what condition you have, and how severely you are affected. They may include one or more of the following.

Non-Medication Treatments :-

Some people are helped by books, websites, leaflets and their own determination. It is thought that about 1 in 3 people who have a problem with alcohol return to sensible drinking, or stop drinking, without any professional help.

Non-Medication Treatments :-

A. UNDERSTANDING

Understanding the cause of symptoms, and talking things over with a friend, family member or health professional may help. In particular, some people worry that the physical symptoms of anxiety such as palpitations are due to a physical illness. This can make anxiety worse. Understanding that you have an anxiety disorder is unlikely to cure it, but it often helps.

B. COUNSELING

This may help some people with certain conditions. For example, counseling which focuses on problem solving skills may help if you have generalized anxiety disorder.

C. ANXIETY MANAGEMENT COURSES

These may be an option for some conditions if they are available in your area. The courses may include: learning how to relax, problem solving skills, coping strategies, and group support.

D. COGNITIVE AND BEHAVIOUR THERAPY

These, if available in your area, can work well for persisting anxiety disorders and phobias.

➙ Cognitive Therapy is based on the idea that certain ways of thinking can trigger, or 'fuel', certain mental health problems such as anxiety and depression. The therapist helps you to understand your current thought patterns. In particular, to identify any harmful, unhelpful and 'false' ideas or thoughts which you have that can make you anxious (or depressed). The aim is then to change your ways of thinking to avoid these ideas. Also, to help your thought patterns to be more realistic and helpful. Therapy is usually done in weekly sessions of about 50 minutes each, for several weeks. You have to take an active part, and are given 'homework' between sessions. For example, you may be asked to keep a diary of your thoughts which occur when you become anxious or develop physical symptoms of anxiety.

➙ Behaviour therapy aims to change any behaviors which are harmful or not helpful. For example, with phobias your 'behaviour' or response to the feared object is harmful, and the therapist aims to help you to change this. Various techniques are used, depending on the condition and circumstances. As with cognitive therapy, several sessions are needed for a course of therapy.

➙ Cognitive Behaviour Therapy (CBT) is a mixture of the two where you may benefit from changing both thoughts and behaviors. (Note: cognitive and behaviour therapies do not 'look into the events of the past'. They deal with, and aim to change, your current thought processes and/or behaviors.)

E. SELF HELP

There are various national groups which can help by giving information, advice and support (see below). They, or your doctor or practice nurse, may also be able to put you in touch with a local group for 'face to face' support.

You can also get leaflets, books, tapes, videos, etc, on relaxation and combating stress. They teach simple deep breathing techniques and other measures to relieve stress, help you to relax, and may ease anxiety symptoms.

Medication :-

A. ANTIDEPRESSANT MEDICINES

These are commonly used to treat depression, but also help to reduce the symptoms of anxiety 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 straight away. It takes 2-4 weeks before their effect builds up. A common problem is that some people stop the medicine after a week or so as they feel that it is doing no good. You need to give it time. It is best to persevere if you are prescribed an antidepressant medicine.

➙ Antidepressants are not tranquillizers, 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, SSRI antidepressants (selective serotonin reuptake inhibitors) are the ones most commonly used for anxiety disorders.

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

B. BENZODIAZEPINES SUCH AS DIAZEPAM

These medicines (sometimes called minor tranquillizers) used to be the most commonly prescribed medicines for anxiety. They usually work well to ease symptoms. The problem is, they are addictive and can lose their effect if you take them for more than a few weeks. They may also make you drowsy. So, now they are not used much for persistent anxiety conditions. A short course of up to 2-3 weeks may be an option for anxiety which is short term, or 'now and then' to help you over a bad spell if you have persistent anxiety symptoms.

C. BUSPIRONE

This is commonly prescribed to treat Generalized Anxiety Disorder. It is an 'anti-anxiety' medicine, but different to the benzodiazepines and is not thought to be addictive. It is not clear how it works. It is thought to affect serotonin, a brain chemical which may be involved in causing anxiety symptoms.

D. BETA-BLOCKER MEDICINES

A beta-blocker, for example Propranolol, can ease some of the physical symptoms such as trembling and palpitations. They do not directly affect the 'mental' symptoms such as worry. However, some people relax more easily if their physical symptoms are eased. These tend to work best in acute (short lived) anxiety. For example, if you become more anxious before 'performing' then a beta-blocker may help to ease 'the shakes'. In some cases a combination of treatments such as Cognitive Therapy and an antidepressant may work better than either treatment alone.

ALCOHOL AND ANXIETY :-

Although alcohol may ease symptoms in the short term, don't be fooled that drinking helps to cure anxiety. In the long run, it does not. Drinking alcohol to 'calm nerves' is often a slippery slope to heavier and problem drinking. See a doctor if you are drinking heavily (or taking street drugs) to ease anxiety.
