法国图卢兹大学附属医院神经退行性疾病研究中心的学者发现,走路速度较慢的老年人其大脑中淀粉样斑块数量较多,而这种淀粉样斑块与老年痴呆症相关。研究团队选取了128名平均年龄为76岁的老年人,虽然他们没有被正式诊断患有老年痴呆症,但却被认为有患上此病的风险,因为他们的记忆力都存在问题。研究者对他们的大脑进行了扫描,以测量淀粉样斑块的含量。此外,这些老年人中有46%的人被归为具有轻度的认知功能障碍,这种疾病会导致老年痴呆症。研究者还测量了这
Researchers at the Center for Neurodegenerative Diseases at the University Hospital Toulouse University in France found that older people with slower walking had more amyloid plaques in their brains, and that this amyloid plaque was associated with Alzheimer’s disease. The team selected 128 older adults, 76 years of age on average, who, although not officially diagnosed with Alzheimer’s disease, were considered at risk because of their memory problems. Researchers scanned their brains to measure the amount of amyloid plaques. In addition, 46% of these elderly people are classified as having mild cognitive impairment that causes Alzheimer’s disease. The researchers also measured this
