A suicide crisis, suicidal crisis, attempted suicide or potential suicide, is a situation in which a person is attempting to kill themselves or is seriously contemplating or planning to do so. It is considered by public safety authorities, medical practice, and emergency services to be a medical emergency, requiring immediate suicide intervention and emergency medical treatment. == Nature== Most cases of potential suicide have warning signs. Attempting to kill oneself or harming oneself, talking about or planning suicide, writing a suicide note, talking or thinking frequently about death, exhibiting a death wish by expressing it verbally or by taking potentially deadly risks, or taking steps towards attempting suicide (e.g., obtaining rope and tying it to a ligature point to attempt a hanging or stockpiling pills for an attempted overdose) are all indicators of a suicide crisis. More subtle clues include preparing for death for no apparent reason (such as putting affairs in order, changing a will, etc.), writing goodbye letters, and visiting or calling family members or friends to say farewell. The person may also start giving away previously valued items (because they "no longer need them"). In other cases, the person who seemed depressed and suicidal may become normal or filled with energy or calmness again; these people particularly need to be watched because the return to normalcy could be because they have come to terms with whatever act is next (e.g., a plan to attempt suicide and "escape" from their problems). Depression is a major causative factor of suicide, and individuals suffering from depression are considered a high-risk group for suicidal behavior. However, suicidal behaviour is not just restricted to patients diagnosed with some form of depression.〔Barker, P. (2003). Psychiatric and Mental Health Nursing ''The craft of caring.'' pp 227. New York, NY: Oxford University Press Inc.〕 More than 90% of all suicides are related to a mood disorder, such as bipolar disorder, or other psychiatric illnesses, such as schizophrenia. The deeper the depression, the greater the risk, often manifested in feelings or expressions of apathy, helplessness, hopelessness, or worthlessness. Suicide is often committed in response to a cause of depression, such as the cessation of a romantic relationship, serious illness or injury (like the loss of a limb or blindness), the death of a loved one, financial problems or poverty, guilt or fear of getting caught for something the person did, drug abuse, old age, concerns with gender identity, among others.〔(【引用サイトリンク】url=https://www.healthforums.com/library/1,1258,article~6229,00.html )〕 In 2006, WHO conducted a study on suicide around the world. The results in Canada showed that 80-90% of attempts failed (an estimation, due to the complications of predicting attempted suicide). 90% of failed suicides investigated lead to hospitalizations. 12% of attempts were in hospitals. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Suicide crisis」の詳細全文を読む スポンサード リンク
