The smaller, the flatter the wave the worse their memory is

and scan them while they are performing

we can try to see if we can target it to enhance it, to improve the memory in older people

It's starting to affect a larger and larger part of our population

因为越来越多的人群受到这一问题的困扰

So being part of the research

所以能参与到

that's aimed at trying to improve cognition in older people is a very exciting process

课程简介和演讲视频

课程简介
本套课程讲解了睡眠对健康的多重影响。睡眠不足会改变身体的内分泌系统，打破激素的平衡，扰乱大脑对食物的选择和摄取从而引发肥胖，严重影响胰岛素的平衡进而引发糖尿病。不同年龄段的人群有不同的睡眠需求，一般而言，年轻人的睡眠需求高于老年人，但所有成年人都应保证每天8小时的睡眠时间。

老年人的睡眠时间减少并不是生理变化的自然结果，而是其他疾病造成的影响，衰老本身并不会降低睡眠需求。常见的睡眠障碍包括失眠、睡眠呼吸障碍、四肢不宁综合症、快速眼动期行为失调，患者需要就具体的睡眠障碍咨询专业的睡眠医生，确诊后有针对性的改善睡眠，进而提高整体的健康状况。

不同的睡眠障碍有不同的治疗方式，但认知行为疗法是所有治疗方法的首选，其次是器械治疗、药物治疗以及外科手术治疗。患者应养成良好的睡眠习惯，培养“睡眠卫生习惯”，改善睡眠质量，尽量避免擅自用药和药物滥用。
