　　Melancholia - clinical depression is a fairly modern term. Hippocrates, known as the father of Western medicine, described a syndrome of "melancholia". He said melancholia was a distinct disease with specific physical and mental symptoms. Hippocrates characterized it as "(all) fears and despondencies, if they last a long time" as being symptomatic of the illness.

　　Death or a loss.丧亲 Sadness or grief from the death or loss of a loved one, though natural, may increase the risk of depression.

　　Genetics.遗传 A family history of depression may increase the risk.

　　A study published in Archives of Psychiatry found that MRI (magnetic resonance imaging) scans showed patients with clinical depression had less brain volume in several regions, including the frontal lobe, basal ganglia and hippocampus. They also found that after treatment the hippocampus returned to normal size.

　　The Stanford School of Medicine says that genes do play a role in causing depression. By studying cases of major depression among identical twins (whose genes are 100% identical) and non-identical twins (whose genes are 50% identical) they found that heritability is a major contributory factor in the risk of developing depression.

　　斯坦福医学院说基因起了很大作用。通过对同卵双胞胎和异卵双胞胎的观察研究，发现遗传因素可能是导致抑郁的主要原因。

　　An article in Harvard Health Publicaitons explains that depression is not caused simply by the level of one chemical being too low and another too high. Rather, several different chemicals are involved, working both within and outside nerve cells.

　　An awful experience can trigger a depressive illness. For example, the loss of a family member, a difficult relationship, physical sexual abuse.

　　抑郁症非常常见，女性患病的几率大大高于男性。很多抑郁症患者不会或者不愿寻求治疗。

　　According to the National Institutes of Health, a significant percentage of people with depressive illness never seek medical help. This is unfortunate, because the vast majority, even those with very severe symptoms, can improve with treatment.

　　How common is clinical depression? - Nobody is sure exactly how many people are affected by depression. Health authorities from country to country and even within the same nation publish different figures:

　　The National Institute of Mental Health estimates that 6.7% of American adults have had depressive illness during the last 12 months, and 30.4% of these cases (2% of the whole adult population) have severe symptoms.

　　While the National Institute of Mental Health says women are 70% more likely to develop depressive symptoms during their lifetime, an article published in JAMA Psychiatry (August 2013 issue) showed thatdepression affects 30.6% of men and 33.3% of women, not a statistically significant difference.

　　The National Institute for Clinical Excellence (NICE) estimates that in the United Kingdom 21 in every 1,000 16-to-65 year olds live with major depression (17/1000 males and 25/1000 females). If "mixed depression and anxiety", a less specific and broader category is included, the prevalence rises to 98 per 1,000.

　　In Australia only 1 in every five people with clinical depression is accurately diagnosed, according to theState Government of Victoria, "because depression can mask itself as a physical illness like chronic pain, sleeplessness or fatigue."

　　抑郁症的种类Types of depression

　　There are several forms of depression (depressive disorders). Major depressive disorder and dysthymic disorder are the most common.

　　Major depressive disorder (major depression)

　　Major depressive disorder is also known as major depression. The patients suffer from a combination of symptoms that undermine their ability to sleep, study, work, eat, and enjoy activities they used to find pleasurable.

　　Experts say that major depressive disorder can be very disabling, preventing the patient from functioning normally. Some people experience only one episode, while others have recurrences.

　　Dysthymic disorder (dysthymia)

　　Dysthymic disorder is also known as dysthymia, or mild chronic depression. The patient will suffer symptoms for a long time, perhaps as long as a couple of years, and often longer. The symptoms are not as severe as in major depression - they do not disable the patient. However, people affected with dysthymic disorder may find it hard to function normally and feel well.

　　Some people experience only one episode during their lifetime, while others may have recurrences.

　　A person with dysthymia might also experience major depression, once, twice, or more often during their lifetime. Dysthymia can sometimes come with other symptoms. When they do, it is possible that other forms of depression are diagnosed.

　　For a patient to be diagnosed with dysthymia he or she must have experienced a combination of depressive symptoms for at least two years.

　　Psychotic depression

　　When severe depressive illness includes hallucinations, delusions, and/or withdrawing from reality, the patient may be diagnosed with psychotic depression. Psychotic depression is also referred to as delusional depression.

　　Postpartum depression (postnatal depression)

　　Postpartum depression is also known as postnatal depression or PND. This is not to be confused with baby blues which a mother may feel for a very short period after giving birth.

　　If a mother develops a major depressive episode within a few weeks of giving birth it is most likely she has developed postpartum depression. Experts believe that about 10% to 15% of all women experience this type of depression after giving birth. Sadly, many of them go undiagnosed and suffer for long periods without treatment and support.

　　Postpartum depression can start any time within a year of giving birth, according to the National Library of Medicine.

　　SAD (seasonal affective disorder)

　　SAD is much more common the further from the equator you go, where the end of summer means the beginning of less sunlight and more dark hours. A person who develops a depressive illness during the winter months might have SAD.

　　SAD symptoms go away during spring and/or summer. In Scandinavia, where winter can be very dark for many months, patients commonly undergo light therapy - they sit in front of a special light. Light therapy works for about half of all SAD patients. In addition to light therapy, some people may needantidepressants, psychotherapy, or both. Light therapy is becoming more popular in other northern countries, such as Canada and the United Kingdom.

　　The National Health Service9, UK, suggest that sunlight may stimulate the hypothalamus, a part of the brain that controls sleep, appetite and mood.

　　Bipolar disorder (manic-depressive illness)

　　Bipolar disorder is also known as manic-depressive illness. It used to be known as manic depression. It is not as common as major depression or dysthymia. A patient with bipolar disorder experiences moments of extreme highs and extreme lows. These extremes are known as manias.

　　抑郁症的迹象和症状
