Memory loss and forgetfulness are common warning signs for dementia. But a dulling of the senses also appears to be associated with the disease.
"Smell is definitely the strongest one we found, but it does seem like it's not just smell."
Willa Brenowitz, an epidemiologist at the University of California, San Francisco. Her team studied cognitive decline in 1,800 adults from the Health, Aging and Body Composition Study—which tracked the health and mental function of older adults over a 17-year period.
During the study, the subjects completed sensory tests—including hearing, smell, touch and vision. Brenowitz's team tooked the results of those tests and then compared the adults' overall sensory abilities to their mental function. And the results?

"Those with better function had a lower risk of dementia. And with worse multiple sensory function, they had higher risk of dementia."
A decline in smell, in particular, had the strongest link to dementia. The results are in the Journal of the Alzheimer's Association: Alzheimer's & Dementia.
The scientists were just studying correlations here. But Brenowitz says if they can figure out how well multisensory decline predicts dementia risk, it might give doctors another tool to screen for the disease.
Thanks for listening for Scientific American's 60-second Science. I'm Christopher Intagliata.

失忆和健忘是痴呆症常见的警告信号Y7eWXQJKXG117UIMAlM。但感官迟钝似乎也与痴呆症有关CUJCa[z-PH%uO.8sQQ。
“嗅觉绝对是我们发现的最强的感觉，但似乎不仅仅是嗅觉td+ujN_&5dy#Q0t9jkIe。”
旧金山加利福尼亚大学的流行病学家威拉·布雷诺维茨说到7.kU,s4O.=,c)tvDmhH。她的团队对“健康、衰老和身体组织研究”中1800名成年人的认识能力减退情况进行了研究，上述研究对老年人的健康和心智功能进行了长达17年的追踪Qr7ZVf.=Xd^%c7。
在研究过程中，研究对象完成了听觉、嗅觉、触觉和视觉等感官测试byI~yEZKt9=&udu。布雷诺维茨的团队拿到了这些测试的结果，之后将这些受试成年人的整体感知能力与心智功能进行了对比#V]Iw7Is%VdP(ka.TS。结果如何？
“功能较好的人患痴呆症的风险较低8cFRGNNs,!X#KyU0^!。而各种感知功能越差，患痴呆症的风险就越高dMtrhhMrhl1;tcD1S。”
尤其是，嗅觉的衰退与痴呆症的关系最为密切O26vZ(|eJ7。这项研究结果发表在《阿尔茨海默症协会期刊：阿尔茨海默症与痴呆症》上qYd+8Fbp8DGsDEVQ,Wp6。
