Treatment is available to help individuals who suffer with depressions however the severity of their depression will determine which treatment will be most helpful for them. Symptoms of depression can vary from one individual to another. The physiological symptoms can range from: continuous low moods, low self-esteem, finding it hard to keep themselves motivated, having difficulty with decision making and having little enjoyment in life which can cause suicidal thoughts. Physical symptoms to look out for are: constipation, lacking in energy and being a lot slower than usual and having sleep troubles. Depression will also cause social symptoms such as: reducing the number of social events attended and trying to avoid social situations. (NHS,2016) There is a wide range of treatments available for people who suffer with depression such as; Counselling and talking therapy, Cognitive behavioural therapy (CBT) and prescribed antidepressants. There are also self-help treatments for mild depression such as exercising. (Mind,2013) Depression is one of the most common mental health issues and for some people there could be an obvious reason for this such as a traumatic life event, stress and illnesses. (CAMHS,2017) There are many factors which can be causes of depression such as; abuse, death of a close relative or friend, drug misuse and family genetics. (MInd,2013) In the UK the trend of depression is increasing. Depression in teenagers between 15 and 16 has doubled from 1 in 30 to 2 in 30 from 1999 and 2004. (Nuffield Foundation) It is estimated that around 300 million people of the world’s population suffer with a form of depression and/or anxiety, these figures were published by the world health organisation (WHO) and women are more likely to have depression in comparison to men.
