最新研究探討愛滋病毒與認知老化之間的關聯
New Research Examines the Link Between HIV and Cognitive Aging
歸功於現代抗反轉錄病毒療法，HIV已從絕症轉變為可控的慢性病。
Thanks to modern antiretroviral therapy (ART), HIV has evolved from a fatal diagnosis into a manageable chronic condition.
因此，許多愛滋病毒感染者都能步入高齡。
As a result, many people living with HIV (PLWH) are reaching older ages.
如今，美國約半數的HIV陽性人口已超過50歲。
Today, about half of the HIV-positive population in the U.S. is over 50.
伴隨這項成就而來的是一個新的臨床焦點：認知老化。
With this success comes a new clinical focus: cognitive aging.
雖然嚴重的愛滋病毒相關失智症現已罕見，但較輕微的記憶力、注意力及執行功能問題（統稱為愛滋病毒相關神經認知障礙，HAND）仍困擾許多人。
While severe HIV-associated dementia is now rare, milder issues with memory, attention, and executive function—collectively known as HIV-Associated Neurocognitive Disorder (HAND)—persist in many individuals.
科學家目前正在調查「加速」假說，該假說認為HIV可能導致大腦加速老化。
Scientists are currently investigating the "acceleration" hypothesis, which suggests that HIV might cause the brain to age faster.
此過程可能由多種因素共同驅動，包括持續性的低水平神經發炎、病毒對神經系統造成的歷史性影響，以及心血管疾病等其他共病症。
This process is likely driven by a mix of factors, including persistent low-level neuroinflammation, the historical impact of the virus on the nervous system, and other health comorbidities like cardiovascular disease.
展望未來，目標是將定期認知篩檢納入標準HIV治療中，確保病患在活得更久的同時，也能維持最佳的生活品質與腦部健康。
Moving forward, the goal is to incorporate regular cognitive screenings into standard HIV treatment, ensuring that as patients live longer, they also maintain the best possible quality of life and brain health.
