澳大利亚的一项新研究发现,创伤性脑损伤可能导致与高痴呆症和帕金森氏病风险有关的持久的大脑变化。 Traumatic brain injuries may cause lasting brain changes linked to higher dementia and Parkinson’s risk, a new Australian study finds.

阿德莱德大学领导的一项澳大利亚新研究发现,创伤性脑损伤,包括脑震荡,可能导致几十年后可以检测到的持久的大脑变化,即使在健康的成年人中也是如此。 A new Australian study led by Adelaide University finds that traumatic brain injuries, including concussions, may cause lasting brain changes detectable decades later, even in healthy adults. 研究人员发现,在具有TBI历史的人中,情绪障碍程度较高,白物质完整性下降,嗅觉下降,以及自主和胃肠问题。 Researchers observed higher mood dysfunction, reduced white matter integrity, diminished sense of smell, and autonomic and gastrointestinal issues in those with a history of TBI. 这些变化与帕金森病和痴呆症的风险增加有关，TBI占痴呆病例的15%，单次受伤会使帕金森病风险增加超过50%。 These changes are linked to a greater risk of Parkinson’s disease and dementia, with TBIs tied to 15% of dementia cases and a single injury increasing Parkinson’s risk by over 50%. 正在进行的研究有600多名参与者参加,旨在发现长期神经系统衰落背后的生物机制。 The ongoing study involves over 600 participants and aims to uncover the biological mechanisms behind long-term neurological decline.
