9·11的PTSD急救人员显示大脑老化更快，这与零点辐射暴露有关。 9/11 first responders with PTSD show brains aging faster, linked to Ground Zero exposure.

利用AI-动力MRI分析进行的一项西奈山研究发现,具有创伤后精神紧张症的9/11第一反应者的大脑明显比其实际年龄大得多,在地面零度接触时间较长使影响恶化。 A Mount Sinai study using AI-powered MRI analysis found that 9/11 first responders with PTSD have brains that appear significantly older than their actual age, with longer exposure to Ground Zero worsening the effect. 该研究在《翻译精神病学》中发表,表明创伤后应激障碍可能导致持久的神经生物学变化,增加与年龄有关的脑疾病的风险。 The research, published in Translational Psychiatry, suggests PTSD may cause lasting neurobiological changes, increasing risk for age-related brain diseases. 脑年龄被确定为监测神经健康的一个潜在生物标志,突出表明需要持续为受创伤影响的个人提供精神和神经护理。 Brain age was identified as a potential biomarker for monitoring neurological health, highlighting the need for ongoing mental and neurological care for trauma-exposed individuals.
