Nature Neurosci:睡眠差居然与老年痴呆相关

2015-06-05 佚名 生物谷

来自加州大学伯克利分校的研究人员们发现老年痴呆症的beta-淀粉样蛋白沉淀,与睡眠差(尤其是非快速动眼期睡眠的中断)及大脑的长时期记忆力减退有关。这项研究揭示了老年痴呆症引起记忆力下降的一种可能的方式,即影响睡眠。相关研究结果于近日在线发表在Nature Neuroscience杂志上。 在此项研究中,研究人员们利用了正电子发射断层扫描(PET)来测量大脑中beta-淀粉样蛋白的沉积量;用功

来自加州大学伯克利分校的研究人员们发现老年痴呆症的beta-淀粉样蛋白沉淀,与睡眠差(尤其是非快速动眼期睡眠的中断)及大脑的长时期记忆力减退有关。这项研究揭示了老年痴呆症引起记忆力下降的一种可能的方式,即影响睡眠。相关研究结果于近日在线发表在Nature Neuroscience杂志上。

在此项研究中,研究人员们利用了正电子发射断层扫描(PET)来测量大脑中beta-淀粉样蛋白的沉积量;用功能性磁共振成像(fMRI)来检测大脑在记忆活动中的活性;用脑电图(EEG)来记录大脑在睡眠时的脑电波;最后,他们利用统计模型来分析所有的数据。

研究人员招募了26名年龄在65到81之间的老年人,他们没有痴呆症,神经退行性病变,睡眠或是精神障碍。首先,这些老年人接受了正电子发射断层扫描(PET),来测量他们大脑中beta-淀粉样蛋白的量。接着,他们被要求记住120个词组,并且检验他们最终记住了多少个。在接下来的8小时睡眠中,脑电图记录了他们的脑电波。第二天早上,这些老年人被要求回想昨天记住的词组,同时他们的大脑接受了功能性磁共振成像的检测,此时,可以检测到大脑海马区域的活性,短暂的记忆被储存在这里,之后这些记忆被传送到前额叶皮层。结果显示,参与者中内侧额叶皮层的beta-淀粉样蛋白最高者,睡眠质量最差,而且,在第二天的词组记忆测试中,参与者忘记了一半以上的前一天所记住的词组。

此项研究提示,大脑中越多的beta-淀粉样蛋白,会导致睡眠质量越差,结果,记忆力也越差。而且,越差的睡眠,也会反过来导致大脑清除这些有害的蛋白的能力越差,这是一种恶性循环。然而,低质量的睡眠和有害的蛋白,哪一个因素是此恶性循坏的起始点,现在仍不清楚。

Brain:科学家发现老年痴呆发病新机制

近日,来自奥斯陆大学的研究人员在国际学术期刊brain发表了一项最新研究进展,他们在小鼠大脑中敲除了两个基因,构建了一种新的阿尔茨海默病小鼠模型,与遗传性阿尔茨海默病小鼠模型不同,对于非遗传性阿尔茨海默病研究有重要意义。 阿尔茨海默病的发生主要是由于大脑中beta淀粉样蛋白异常沉积引起,这会导致神经元网络损伤,并引起一些临床症状,如方向障碍,记忆丢失,行为变化并最终导致死亡。在关于阿尔茨

Mol Psychiatry:p75ECD减少可能与老年性痴呆发生有关

老年痴呆症是一种以进行性、不可逆的记忆力减退和认知功能障碍为主要表现的神经退行性疾病,是最常见的痴呆。目前全球范围有老年痴呆症患者大概有3650万,预计到2050年老年痴呆症患者将超过1个亿,已成为全球面临的重要健康问题。然而,目前尚无阻止或延缓疾病进展的防治方法。 β淀粉样蛋白(Aβ)被认为是老年痴呆症的重要致病物质。过去20年中以Aβ为靶点的临床试验均未成功,干预靶点单一是原因之一。

200万人群调查:BMI过低会诱发老年痴呆!

当前社会中,痴呆与肥胖是困扰现代人类的两项严重的健康问题,而且其危害程度仍在不断上升。有研究认为中年时期的肥胖很有可能会导致老年的痴呆症状。因此,在2015年4月10日The Lancet Diabetes & Endocrinology杂志在线发表的一篇文章中,作者利用回顾性队列研究的方式,探查了BMI与痴呆风险之间的联系。 在这项研究中,作者从英国临床实践研究数据链(CPRD)的数据

新型老年痴呆药物已进入临床试验!

近日,来自兰卡斯特大学的研究人员通过研究开发了一种新型药物,该药物可以帮助抑制早期阿尔兹海默氏症的发生,目前已经进入临床试验阶段。近年来患痴呆症个体的数量不断增加,目前在英国有85万痴呆症患者,而且研究者预测到2021年痴呆症患者的数量将会达到100万,最常见的痴呆症就是阿尔兹海默氏症,当β淀粉样蛋白形成衰老斑块并在大脑中积聚时,阿尔兹海默氏症就开始发生了,这种斑块会损伤大脑神经细胞并且引发记忆丧

Lancet:多途径共同干预可预防老年痴呆(FINGER研究)

在既往的多项观察性研究中,都报道了痴呆的风险与多种血管或其他生活方式相关的风险因素有密切的联系。在芬兰老年健康、预防认知损伤研究(FINGER)中,研究人员为了验证概念,进行了一项随机对照试验,试图评估一种多途径的方法预防大众中高风险老年人群的认知损伤。该结果在线发表于2015年3月13日的The Lancet杂志上。 该试验时一项双盲的随机对照试验,研究人员募集了60-77岁的老年人,这些人均

Nat Commun:铁蛋白和老年痴呆有关系?!

近日,一篇发表于国际杂志Nature Communications上的研究论文中,来自墨尔本大学的一项研究表明,高水平的铁蛋白或许和个体轻度认知损伤向阿尔兹海默氏症过渡直接相关。文章中研究人员对91名认知正常的个体、144有轻度认知损伤的个体及67名阿尔兹海默氏症个体进行了长达7年的研究,研究结果显示,在那些轻度认知损伤个体的脑脊髓液中较高水平的铁蛋白或许和其向阿尔兹海默氏症转换直接相关,而铁蛋白
