科学领域:

  • 神经科学是一个神经科学.
  • 老年学是指老年学的学科.
  • 流行病学 流行病学

背景情况:

  • 与年龄相关的听力损失 (HL) 是认知障碍和痴呆症的可修改风险因素.
  • 了解听力值与大脑健康之间的关系对于痴呆症预防策略至关重要.

研究的目的:

  • 调查纯音调平均 (PTA) 听力值与大脑衰老,血管损伤和认知功能的相关性.
  • 为了确定中年听力损失是否预测了随着时间的推移发展痴呆症的风险.

主要方法:

  • 利用了1656名弗雷明汉心脏研究参与者的数据 (平均年龄58岁),没有中风和痴呆症.
  • 计算PTA值和定义听力损失类别;采用多变量回归和Cox比例危险模型.
  • 在4-8年内评估大脑MRI,认知功能和发病性痴呆症,并根据年龄,性别,教育和APOE-4状态等共变量进行调整.

主要成果:

  • 轻度听力损失与较小的大脑体积 (相当于1.75年衰老) 和执行功能下降相关.
  • 较高的PTA与白质超强度体积增加有关.
  • 轻微或较大的听力损失 (>16dB) 增加了71%的痴呆风险,特别是在APOE-4载体中.

结论:

  • 中年听力损失与加速的大脑衰老,认知能力下降和痴呆风险增加有关.
  • 这些发现表明听力损失可能在痴呆症发展中起因性或生物标志物作用.
  • 针对中年人群听力损失的干预措施可能是预防痴呆症的战略.
