慢性疲劳症候群

title: 病征.
content: 慢性疲劳症候群的病征很多元化,计有: 虽然疲劳是一种在很多疾病都会出现的病征,但CFS的各种病征是多系统的,而且往往很少因为一种病症所引起而同时发生,所以是有办法分辨出来的。
title: 病因.
content: 在1980年代晚期和1990年代初期,人类疱疹病毒第四型曾经被认为是一种可以引起慢性疲劳症候群的病毒,但后来证实了该病并非由单一因素引起。目前医界认为慢性疲劳症候群可能是由病毒感染、免疫系统问题、神经系统问题、精神疾病等多重因子造成。过去临床及流行病学研究的结果对环境及其它风险因素的关系仍未能达到一致的看法。
title: 诊断.
content: 慢性疲劳症候群在目前为止仍无任何化验可作为诊断。在传统中医学把有关病征归类为「虚劳」;而在西医学,它的诊断是根据美国疾病控制与预防中心之定义,患者须全部符合下列2项:
title: 治疗.
content: 目前对于慢性疲劳症候群并无有效的治疗方法,也无有用之检测指标,但中西医学上,仍有许多推断认为这些疗法可能具有疗效或改善病征之效益;在西医学上,有透过补充血清素来改善病征;而在中医学,有采用复方起阳籽来调理身体的阴阳平衡,从而改善患者的体质;又或与一般情绪病一般,透过服用甘麦大枣汤来调理五脏六腑间的问题。另外,针灸与气功疗法也被认为可能具有疗效或改善病征的功用。

Summary: 慢性疲劳(倦)症候群(英语:chronic fatigue syndrome, CFS、myalgic encephalomyelitis (ME)),又称为肌痛性脑脊髓炎(myalgic encephalomyelitis),(脊髓炎是有争议的,另一种说法为可能是由于心理焦虑引起,可能是广泛性焦虑症的身体症状) 。为一种身体出现慢性的持续性疲劳症状的病症而无法恢复,诊断的定义是发生期间达连续6个月以上,且排除已知的疲劳原因后的不明原因的疲劳感觉或身体不适。目前这类疾病的危险因子仍认识不多,在病因或病理学成因上也仍不明,在过去曾认为是病毒所引起的疾病,但是科学证据力仍不足以支持这样的论点。绝大部分的患者都与工作紧张与压力过大,以及长期生活作息不正常等有关;若长期任由身心疲累,没有好好调养,可能会引发一些危险因子,从轻微的「疲劳」演变成严重的「过劳」。在2015年,美国国家医学研究所(Institute of Medicine, 简称IOM)提出了重新定义这类疾病的诊断标准,并重新命名为系统性运动不耐疾病(systemic exertion intolerance disease, 简称SEID).

Chronic fatigue syndrome: Chronic fatigue syndrome (CFS), also referred to as myalgic encephalomyelitis (ME), is a complex, fatiguing, long-term medical condition that causes worsening symptoms after physical or mental activity, a greatly lowered functional ability to complete routine daily activities compared to prior onset of the disease, and unrefreshing sleep. Difficulty sitting and standing upright or cognitive dysfunction are also present. Other common symptoms may involve numerous body systems in those affected. While the cause is not understood, proposed mechanisms include biological, genetic, infectious, and physical or psychological stress affecting body chemistry. Diagnosis is based on a person's symptoms because there is no confirmed diagnostic test. The fatigue in CFS is not due to strenuous ongoing exertion, is not much relieved by rest and is not due to a previous medical condition. Fatigue is a common symptom in many illnesses, but the unexplained fatigue and severity of functional impairment found in CFS is comparatively rare in these other illnesses. Persons with CFS may recover or improve over time, but there are no approved therapies or medications for the illness; treatment is directed toward improvement in symptoms. The CDC recommends the use of pacing (personal activity management) to reduce the worsening of symptoms resulting from mental or physical activity. Limited evidence suggests rintatolimod, counseling therapies, and graded exercise therapy might benefit some patients. Estimates of the number of people with the condition vary widely, from 7 to 3,000 per 100,000 adults. Studies estimate that 836,000 to 2.5 million Americans and 250,000 people in the UK have CFS. CFS occurs 1.5 to 2 times more often in women than in men. It most commonly affects adults between ages 40 and 60 years, but can occur at other ages including in children. Other studies suggest that around 1 in 200 children have CFS, and is more common in adolescents than younger children. Chronic fatigue syndrome is a major cause of school absence. There is agreement that CFS has a negative effect on health, happiness and productivity, but there is also controversy over many aspects of the disorder. Physicians, researchers and patient advocates promote different names and diagnostic criteria, while evidence for proposed causes and treatments is often contradictory or of low quality.
