摘　要：摘　要：随着现代社会工业的发展，空气污染日益严重，空气污染对人体的损害也越来越大。空气污染中的有害物质，能通过各种途径引起各系统的疾病，甚至会影响儿童的身体和智力发育。研究发现，长期暴露或急性暴露在某些空气污染物中可以直接损伤中枢神经系统，或污染物引起呼吸系统和免疫系统等产生有害因子，通过外周循环到达大脑，导致大脑的神经炎症、神经毒性、氧化应激等反应，最终产生神经退行性病变，如阿尔茨海默病(Alzheimer’s disease，  AD)、帕金森病(Parkinson’s disease， PD)等。

Abstract: Abstract: With the quick development of modern industry， air pollution has been exploding in the past decades， which consequently results in more and more damage to human body. Environmental toxins from polluted air can cause pathologic change of every system in our body and even influence body and intelligence development of children. Recently， it has been reported that chronic exposure or acute exposure to the pollution matters could cause direct damage on the central nervous system (CNS)， or stimulate some susceptible system (e.g.， the respiratory system， immune system， etc.) to produce some harmful factors， which can reach the brain though peripheral circulation and then cause neuroinflammation， neurotoxicity， oxidative stress， eventually result in neurodegenerative diseases， such as Alzheimer’s disease and Parkinson’s disease. This review focuses on the pathways and the mechanisms of neurodegenerative diseases caused by air pollution.
Key words:  air pollution; neuroinflammation; neurotoxicity; oxidative stress; neurodegenerative diseases
