项目摘要

Background: Blows to the head sustained during contact sport can lead to subconcussive impacts1. Whilst subconcussive impacts do not cause acute concussion symptoms, they do lead to microstructural and functional changes to the brain and are linked to neurocognitive impairment2. It is now thought that cumulative subconcussive head impacts cause the neurodegenerative disease Chronic Traumatic Encephalopathy (CTE), which leads to brain atrophy and changes in mood and cognitive ability3. This project will inform and guide educational management of sport-related subconcussive head impacts by determining how cognitive skills are affected by subconcussion, using a novel combination of accelerometry, electroencephalography, and cognitive tests.Concussion symptoms are known to have adverse effects on academic learning4, which in turn can negatively impact mental health5. One possible reason for these adverse effects is due to impairment in cognitive functioning6. Educational environments are often noisy and distracting, and the brain needs to be able to cope with this environment to support academic achievement. The extent to which subconcussive impacts have functional consequences for everyday cognitive functioning, such as the ability to understand and remember information in noisy environments, is currently unknown. It is also unclear whether subconcussions are linked to changes in mental health. And this is despite the far higher prevalence of cumulative subconcussive head impacts relative to concussions.

背景：在接触性运动中头部受到持续的撞击会导致亚震荡性撞击1。虽然亚震荡冲击不会引起急性脑震荡症状，但它们确实会导致大脑的微观结构和功能变化，并与神经认知障碍有关2。现在认为，累积的亚震荡头部撞击会导致神经退行性疾病慢性创伤性脑病（CTE），导致脑萎缩以及情绪和认知能力的变化3。该项目将通过使用加速度计、脑电图和认知测试的新颖组合来确定亚脑震荡如何影响认知技能，从而为与运动相关的亚脑震荡头部撞击的教育管理提供信息和指导。已知脑震荡症状对学术学习有不利影响4，这反过来会对心理健康产生负面影响5。这些不良反应的一个可能原因是认知功能受损6。教育环境通常是嘈杂和分散注意力的，大脑需要能够科普这种环境，以支持学术成就。亚震荡冲击对日常认知功能的影响程度，例如在嘈杂环境中理解和记忆信息的能力，目前尚不清楚。目前还不清楚亚脑震荡是否与心理健康的变化有关。这是尽管累积的亚震荡头部撞击相对于脑震荡的患病率要高得多。
