【medical-news】慢性头痛者害怕“亲密接触”可能
NEW YORK (Reuters Health) - Many patients with chronic headaches are often overly sensitive to touch and ordinary activities like rubbing the head or combing the hair cause pain, according to findings from the American Migraine Prevalence and Prevention Study.
This problem, technically referred to as "cutaneous allodynia," is nearly twice as common among patients with migraines as among those with other types of headache.
As reported in the journal Neurology, Dr. Marcelo E. Bigal, at Merck Research Laboratories in Whitehouse Station, New Jersey, and his group analyzed questionnaires completed by nearly 17,000 headache sufferers.
Up to 69 percent of migraine patients had cutaneous allodynia, the results indicate, compared with just 37 percent of patients with other types of chronic headache. Severe allodynia was noted in 12 to 29 percent of migraine patients, but in no more than 6 percent of patients with other types of headache.
"Cutaneous allodynia appears to map onto migraine biology and to the migraine spectrum," the authors note.
In all headache types, allodynia was more common among women, and severity was associated with symptoms of depression. In migraine patients, allodynia was associated with high attack frequency, long disease duration, obesity and younger age.
In a journal press release, Bigal suggests that cutaneous allodynia "may be a risk factor for migraine progression, where individuals have migraines on more days than not."
"It may be," he continues, "that individuals with allodynia should be more aggressively treated in order to prevent migraine progression, as well as to decrease this sensitivity on the skin."

头痛和皮肤痛感相关联
NEW YORK (Reuters Health) - Many patients with chronic headaches are often overly sensitive to touch and ordinary activities like rubbing the head or combing the hair cause pain, according to findings from the American Migraine Prevalence and Prevention Study.
纽约（路透社健康专栏）-根据美国偏头痛流行和预防研究显示：许多患有慢性头痛的病人常常对一般的接触和日常活动反应过度敏感，如摩擦头皮或梳头都会导致疼痛。
This problem, technically referred to as "cutaneous allodynia," is nearly twice as common among patients with migraines as among those with other types of headache.
这个问题，学术上涉及到“皮肤异常性疼痛”，这种情况，在偏头痛患者中大约是其他类型头痛患者的两倍。
As reported in the journal Neurology, Dr. Marcelo E. Bigal, at Merck Research Laboratories in Whitehouse Station, New Jersey, and his group analyzed questionnaires completed by nearly 17,000 headache sufferers.
《神经病学》杂志报道，Marcelo E. Bigal医生，默克研究实验室，Whitehouse Station，新泽西，和他的团队分析了17,000分头痛患者的问卷调查。
Up to 69 percent of migraine patients had cutaneous allodynia, the results indicate, compared with just 37 percent of patients with other types of chronic headache. Severe allodynia was noted in 12 to 29 percent of migraine patients, but in no more than 6 percent of patients with other types of headache.
这个结果显示，和其他类型慢性头痛患者的37%的比例相比，超过69%的偏头痛患者有皮肤异常性疼痛。严重的皮肤异常性疼痛占偏头痛患者的12%-29%，但在其他类型头痛中，这个比例不足6%。
"Cutaneous allodynia appears to map onto migraine biology and to the migraine spectrum," the authors note.
作者指出“皮肤异常性疼痛看来好像印上了偏头痛的生物学和偏头痛谱”
In all headache types, allodynia was more common among women, and severity was associated with symptoms of depression. In migraine patients, allodynia was associated with high attack frequency, long disease duration, obesity and younger age.
在所有头痛类型中，异常性疼痛在女性中更为常见，其严重程度和情绪低落相关。对于偏头痛患者，异常性疼痛和如下因素有关，如：发作频率高、病程长、肥胖和年纪轻。
In a journal press release, Bigal suggests that cutaneous allodynia "may be a risk factor for migraine progression, where individuals have migraines on more days than not."
在一份杂志发表的文章中，Bigal提出皮肤异常性疼痛“可能对偏头痛的进展是一个危险因素，这些患者比那些没有这种情况的患者偏头痛持续更长时间。”
"It may be," he continues, "that individuals with allodynia should be more aggressively treated in order to prevent migraine progression, as well as to decrease this sensitivity on the skin."
