The following are some specific types of depression which have been identified.
Bipolar disorder (Manic depression)
About one per cent of the population will experience bipolar disorder at some time in their lives. A diagnosis of bipolar disorder means that you have both ‘high’ and ‘low’ mood swings, along with changes in thoughts, emotions and physical health. The mood swings are normally more extreme than everyday ups and downs. This problem is sometimes also referred to as manic depression. Most people with bipolar disorder have their first episode of depression in their late teens or early twenties, and without treatment it is very likely to recur.
Post-natal Depression
About 10 to 15 per cent of women experience post-natal depression in the first year after having a baby. They may be unusually tearful, anxious or irritable, and may also find it difficult to play with their babies and respond positively to them. Although most women get the so-called ‘baby blues’ in the first few days after childbirth because of rapid hormone changes, post-natal depression is very different from this and lasts longer. It is probably due to a mixture of biological, psychological and social factors, and women are particularly at risk of post-natal depression if they do not have a supportive partner or family to help them.
If you seem to be showing signs of post-natal depression your Health Visitor should be able to assess you and either provide help or refer you to another professional. Most women with post-natal depression are helped by supportive counselling, by talking to other women who have been through a similar experience, and by anti- depressant medication.
Seasonal Affective Disorder (SAD)
Some people describe feeling depressed regularly at certain times of the year. A key feature of this kind of depression is the desire to sleep more and eat carbohydrate foods. Usually this kind of depression starts in the autumn or winter, when daylight is reduced. If you experience this kind of depression you may be helped by specially designed bright light therapy.
