新研究表明，嗓音障碍，包括音高、音量或清晰度的变化，可能提示今后罹患痴呆症或认知障碍的概率更高。
New research suggests that voice disorders, including shifts in vocal pitch, volume or clarity, could indicate a higher probability of developing dementia or cognitive impairment in the future.
一项涉及833,417名50岁及以上参与者的研究，考察了嗓音障碍、听力损失或两者同时存在与罹患认知障碍或痴呆症（包括阿尔茨海默病）之间的关联，研究从嗓音障碍和听力损失确诊一年后开始。
A study involving 833,417 participants aged 50 and older examined the connection between a voice disorder, hearing loss, or both with the chance of developing cognitive impairment or dementia, including Alzheimer’s disease, beginning a year after the voice disorder and hearing loss diagnoses.
由费城德雷塞尔大学医学院团队开展的一项研究，其结果发表于《声音杂志》。
The findings from the study, conducted by a team at the Drexel University College of Medicine in Philadelphia, were published in the Journal of Voice.
研究发现，日常任务或有助于在确诊前发现早期痴呆症迹象。结果显示，患有嗓音障碍但没有听力损失的参与者，未来罹患痴呆症或认知问题的可能性增加了58%；而同时患有嗓音障碍和听力损失的参与者，这一可能性增加了104%.在所有患有嗓音障碍的参与者中，无论是否伴有听力损失，其罹患痴呆症或认知障碍的概率均增加了29%；而仅有听力损失者的风险增加了27%.“我们发现，在同时出现嗓音障碍和听力损失的患者中，与痴呆症的联系最为密切。”德雷塞尔大学医学院教授兼系主任罗伯特·萨塔洛夫据《科学预警》报道表示。
EVERYDAY TASK MAY HELP DETECT EARLY DEMENTIA SIGNS BEFORE DIAGNOSIS, STUDY FINDS Results showed that participants with a voice disorder but no hearing loss had a 58% increased likelihood of developing dementia or cognitive issues in the future, whereas participants with a voice disorder and hearing loss had a 104% chance. For all participants with voice disorders, with or without hearing loss, there was a 29% increased probability of developing dementia or cognitive impairment, whereas those with only hearing loss had a 27% greater risk. "We found the strongest link with dementia among patients experiencing a voice disorder and hearing loss," said Robert Sataloff, a professor and chair at the Drexel University College of Medicine, Science Alert reported.

据克利夫兰诊所介绍，嗓音障碍包括喉炎、声带麻痹、声带病变和痉挛性发音困难（喉肌张力不全）等。
Examples of voice disorders include laryngitis, vocal cord paralysis, vocal cord lesions and spasmodic dysphonia (laryngeal dystonia), among others, according to the Cleveland Clinic.
尽管嗓音问题与痴呆症之间可能存在相关性，研究人员指出，接受嗓音障碍治疗也可能有益于患者的大脑。
Regardless of the possible correlation between vocal issues and dementia, researchers noted that seeking treatment for a voice disorder could also benefit a patient’s brain.
生活方式新闻。听力丧失和言语障碍可能使人们不愿与他人交往，研究显示，社交互动能够刺激大脑，并有助于预防痴呆。

萨塔洛夫表示，声音障碍与听力丧失之间存在联系“是很自然的”。
Sataloff said that it’s "only natural" for voice disorders and hearing loss to be connected to cognitive impairment.
他指出，那些在说话或唱歌时感到疼痛或不适的人，可能“较少参与有助于大脑健康的社交或其他益智活动”。
Those who experience pain or discomfort when talking or singing might "participate less often in brain-supporting social or other engaging activities," he noted.
参与我们最新生活方式问答，测试一下自己。尽管研究得出了上述结论，但存在声音障碍并不一定意味着日后必定会出现认知功能损伤。
Despite the study's findings, having a voice disorder doesn’t necessarily mean that future cognitive impairment is absolutely certain.
此外，声音问题也不一定表明脑功能开始衰退，或痴呆、阿尔茨海默病即将发作。
Additionally, it’s not guaranteed that vocal issues indicate the beginning of a decline in brain function or the onset of dementia or Alzheimer’s.
