Anxiety
Anxiety is a common experience that can be a useful motivator or even lifesaver in situations that are objectively dangerous. However, when the anxiety is out of proportion to the danger inherent in a given situation, is persistent and is markedly disabling, an anxiety disorder can be developed.
Anxiety is an emotion that all people experience from time to time, and we do that for very good reasons. It has been built into us; we have inherited it from our evolutionary past, because, in general, anxiety has a survival function. If there is a real danger for a primitive man, then anxiety kicks in in an adaptive way. We freeze, we stop doing whatever we were doing, we devote all of your attention to the danger, and our bodies react with a big release of adrenalin, an increase in blood flow to the muscles, getting us ready to run as fast as we can or fight as fiercely as we can.
So some anxiety is adaptive, not only for primitive man, but in modern society as well. It helps us to focus on things when we have deadlines and, if someone is driving too fast when we cross the road, it helps us to jump out of the way quickly. So, there is nothing wrong with anxiety in general, and in fact, we would have difficulties if we did not experience it to some extent, but of course, it can get problematic if the danger is one that is imagined rather than real, or the danger is something that is exaggerated. In those cases, particularly if the perceived danger is out of proportion to the real danger, and it is persistent and disabling, then there is a danger of an anxiety disorder. About 17 per cent of the population will have an anxiety disorder at some stage in their life.
Anxiety can be caused in a variety of different ways, but any mental disorder is always difficult to diagnose. Scientists are looking at what role genes play in the development of these disorders and are also investigating the effects of environmental factors, such as pollution, physical and psychological stress, and diet. Several parts of the brain are key actors in the production of fear and anxiety. Using brain imaging technology and neurochemical techniques, scientists have discovered that the amygdala plays a significant role in most anxiety disorders. By learning more about how the brain creates fear and anxiety, scientists may be able to devise better treatments for these disorders.
Anxiety disorders are a very costly problem in terms of society. Some published figures show that, in the US, it cost $60 billion in one year in terms of lost productivity and in terms of excessive medical investigations that many people with anxiety seek, often thinking they have a physical problem.
Given all of this, it is rather worrying that anxiety also has a rather low treatment-seeking rate. Only 10 per cent of people with an anxiety disorder will seek treatment. That seems to be largely because people do not realise there are effective treatments available. Most people tend to think they have had it for most of their lives, so it is just their personality and they cannot change their personality, and so they feel rather hopeless about it.
The first psychotherapy treatment that was shown to be effective was exposure therapy, which essentially encourages people in a graded way to go into their feared situations and stay in them as long as they can and build up their confidence that way. Often, the therapist will accompany the person to a feared situation to provide support and guidance. Group cognitive behaviour therapy has also been shown to be effective. This is a talking therapy that helps people to understand the link between negative thoughts and mood and how altering their behaviour can enable them to manage anxiety and feel in control.
There are, of course, drugs that can help people with anxiety. Medication will not cure an anxiety disorder, but it can keep it under control while the person receives psychotherapy. The principal medications used for anxiety disorders are antidepressants, anti-anxiety drugs, and beta-blockers to control some of the physical symptoms. With proper treatment, many people with anxiety disorders can lead normal, fulfilling lives.
There is plenty of evidence that exercise can help with anxiety problems. When stress affects the brain, with its many nerve connections, the rest of the body feels the impact as well. Exercise and other physical activity produce endorphins, which are chemicals in the brain that act as natural painkillers. In addition to this, getting physically tired can help people fall asleep faster and have deeper and more relaxing sleep. As many people suffering from anxiety often have problems with insomnia, just the ability to get a good night’s rest can change people’s whole perspectives.
Anxiety is a normal, but highly subjective, human emotion. While normal anxiety serves a beneficial and adaptive purpose, anxiety can also become the cause of tremendous suffering for millions of people. It is important that people recognise excessive anxiety in themselves as soon as possible, as treatment can be very successful and living untreated can be a misery.
