睡眠呼吸暂停综合征患者脑损伤有性别差异

  美国加州大学洛杉矶分校研究人员日前公布的研究报告称,在睡眠呼吸暂停综合征患者中,女性脑部所受损伤大于男性。

  在这项研究中,研究人员对比了10名新确诊患有阻塞性睡眠呼吸暂停综合征且未接受治疗的女性、20名存在同样情况的男性及50名健康男女的大脑状况。他们发现,女性患者的大脑白质受损更多,其受影响的部位主要是大脑前部的扣带束和前扣带皮层。这些大脑区域主要负责作决定和情绪调控,这些女性患者也因此更容易出现高血压和焦虑症状。

  相关研究报告已发表在美国《睡眠》杂志12月刊上。研究人员表示,他们目前还不能确定睡眠呼吸暂停综合征与大脑损伤之间是否存在因果关系,其下一步计划是揭示睡眠呼吸暂停综合征患者大脑发生变化的时间点。

  阻塞性睡眠呼吸暂停综合征是一种常见的睡眠障碍,患者睡眠过程中气道反复阻塞导致不断出现呼吸暂停,最典型的症状就是打鼾。症状发作时,患者血液中的氧分下降,最终导致体内细胞受损,如不接受治疗,最终可能导致高血压、中风、心脏病、糖尿病等严重健康问题。
