Although it is not fully known what exactly causes clinical depression. There are numerous theories about causes, e.g. biological, genetic factors, chemical, environmental influences, and childhood or developmental events. However, it is generally believed that clinical depression is most often caused by the influence of more than just one or two factors. At times depression has a clear cause. Such as, a major changes in their life (moving house, losing a job, having a baby) can lead to a period of depression. However, in some people, it is difficult to find a cause, and depression appears to strike 'out of the blue'.
The cause of depression can be understood in several different ways.
Psychological: in which a life event such as the loss of a partner, or job causes persistent low mood and feelings of low self-esteem and hopelessness about the future.
Chemical: in which depression is caused by changes in levels of chemicals in the brain, which are fundamental to its workings.
Social: in which reduced activities or interests both cause depression and arise from depression.
The cause of depression is best understood when we consider all of these aspects together (psychological, physical, chemical and social) relating to each other.
Physical treatments (such as antidepressants), psychological treatments (such as Cognitive Behavioural Therapy), and social treatments (such as increased activities and befriending) are all effective in the treatment of depression.
Some people are more likely than others to develop depression, predisposed to develop depression. The most common factor, which predisposes people to depression, is having close relatives who also have depression.
Substance abuse such as drinking alcohol or using street drugs such as cannabis, ecstasy or cocaine can trigger depression, as can certain physical illnesses or medicines prescribed by your doctor.

Major life event, such as the break-up of a relationship or job loss, requires a period of adjustment. During this time, people’s emotions may be upset, with periods of depression, stress, anxiety, irritability, and lack of sleep. Although it normally settles down over a period of days or weeks without the need for treatment. However, if the symptoms persist for more than a few weeks, or are severe, it is possible that a depressive illness is present.
Anxiety
- Anxiety disorders are illnesses in which the main symptom is worry about a real or imagined threat. Anxiety disorders can exist alone, without depression, however, often they can lead to depression, also depressions can lead to anxiety. For these reasons, it can be difficult to distinguish between a depressive illness and anxiety. The HAD scale (Hospital anxiety and Depression Scale) has 14 questions which can help to distinguish between the anxiety and depression.
Depression is very common and much misunderstood; It affects people of all ages. It is estimated that 1 in 4 people will suffer from depression at some point in their lives, Most of us feel miserable or fed up at times, for a short period, a few days or maybe a few hours at a time. Depression involves feeling low or sad more intensely and for longer, and can persist for weeks or months rather than days.
