一項新研究的結果表明,一些偏頭痛患者可能面臨腦損傷風險增加。這些發現今天發表在《美國醫學會雜誌》上,可能表明這種使人衰弱的頭痛在某些情況下是一種進行性腦疾病。

這項研究調查了295名年齡在30至60歲之間的患有偏頭痛的荷蘭成年人,其中一些人有視覺障礙(或先兆,用技術術語來說),另一些人沒有,以及140名無偏頭痛的對照組受試者。研究人員使用磁共振成像技術,由荷蘭萊頓大學醫學中心的馬克·C·克魯伊特領導,掃描了參與者的大腦,以尋找腦梗塞(由於缺氧而死亡的組織,即血栓阻塞動脈的結果)和白質病變。他們發現,無先兆偏頭痛患者的梗塞風險是對照組的七倍;有先兆偏頭痛患者的風險約為對照組的13倍,對於每月發作一次或以上的受試者,風險增加近16倍。

在隨刊評論中,阿爾伯特·愛因斯坦醫學院的理查德·B·利普頓和朱莉·潘寫道,偏頭痛“不應僅僅被概念化為一種發作性疾病,而應被概念化為一種慢性發作性和有時慢性進行性疾病。” 他們說,隨著思維方式的轉變,治療策略也可能發生變化。“如果克魯伊特等人證實的腦損傷具有顯著的臨床相關性,那麼預防腦損傷的積累可能成為治療的額外目標。”

She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
