According to the Royal College of Psychiatrists, anxiety disorders affect about one in 10 people in the UK. We look at how to spot the symptoms and get treatment to prevent them.
Anxiety is the feeling of fear we get when faced with threatening or difficult situations. Anxiety is normal and can help us to avoid danger. It makes us more alert and gives us the energy to deal with problems. But if the anxiety is too strong or is there all the time, it can be a real problem.
Is anxiety different from depression?
Anxiety has quite different symptoms from depression; if you’re depressed you’ll suffer from low mood, reduced energy and lose interest in things, but if you’re anxious you’re agitated, have increased energy and can maintain your interests.
People with depression are self-critical and regret past behaviour, but anxious people worry about the future. However, if you’re anxious you may stop doing things and become isolated and depressed as a result.
Anxiety only becomes a problem if it’s interfering with your daily life.
A panic attack is a sudden surge of intense anxiety that can come from nowhere. Whilst feeling panic and anxiety is normal in stressful or dangerous situations, people who suffer from panic attacks can suffer from these feelings at any time, for no apparent reason.
Symptoms peak within 10 minutes and usually subside after half an hour. They are not dangerous but can feel very frightening.
How common are panic attacks?
One in 10 people will have a panic attack at some point in their life, one in 20 will have recurrent attacks and one in 50 (2 per cent) will suffer from panic disorder – defined as regular, unexpected panic attacks. Symptoms usually begin before the age of 20.
Physical symptoms for panic attacks
Symptoms are experienced by the body producing the so-called ‘fight or flight’ hormone adrenaline and include:
- Heart palpitations
- Rapid breathing
- Tingling in the fingers and around the mouth
- Dry mouth.
Is it a heart attack?
About a quarter of people who go to an A&E department with chest pain, thinking they’re having a heart attack, are actually having a panic attack.
So what's the difference?
Heart attacks are characterised by crushing central chest pain – usually on the left and also in the arm – but in a panic attack there is no pain. Heart attack symptoms will get worse but a panic attack will usually subside after half an hour.
Psychological symptoms of panic attacks
People experiencing a panic attack will feel intensely worried, agitated and fearful. They often describe feeling like they are going to die or frightened they’re 'going crazy' or losing control.
What causes anxiety and panic attacks?
No-one knows for sure – but there are certain triggers. These include:
- Your genes: Some of us are born worriers. This tendency might be inherited.
- Stressful events: Divorce, money worries, bereavement, redundancy and exams are obvious triggers for anxiety, but usually when the problem disappears, so does the anxiety. But other traumatic events such as car crashes, assaults and fires can leave you feeling nervous and anxious for months or years – known as post-traumatic stress disorder.
- Drugs: Illegal highs from amphetamines, LSD or ecstasy can make you anxious – as can excess caffeine.
If you’ve only ever had one panic attack, your doctor is unlikely to prescribe treatment, as 50 per cent of patients never experience another attack, but if you have a recurrent problem you may need either drugs or psychological therapy or a combination of both.
- Cognitive behavioural therapy (CBT), or talking therapy, can alleviate feelings of anxiety and panic and help change how you think and act. CBT focuses on current problems rather than things that have happened in the past.
- Exposure therapy: “If your panic attacks or anxiety are triggered by a specific fear, such as fear of enclosed spaces, you can use CBT techniques to help expose yourself to your particular trigger for a short period,” advises Professor Baldwin.
- Anti-depressants: Selective Serotonin Reuptake Inhibitors are frequently prescribed for people with anxiety who suffer from panic attacks. “They work even though you’re not depressed,” explains Professor Baldwin. Treatment is effective in around 65 per cent of patients.
- Beta blockers: These can be prescribed in low doses to control shaking etc.
If psychological therapies are combined with anti-depressants, 85 per cent of patients respond.
- Talk your fears through: Tell someone you trust who has had the same problem or knows someone who has.
