“…Examining the long-term ramifications of exposure to LLB is particularly significant due to its potential to contribute to chronic deficits in cerebral perfusion by accelerating aging-related mechanisms in cerebrovascular dysfunction, such as reductions in nitric oxide (NO) availability and neurovascular oxidative stress [ 108 ]. Notably, preclinical investigations have demonstrated that blast exposure triggers acute oxidative stress [ 21 , 44 , 60 , 109 , 110 ] and alters NO production [ 60 , 111 , 112 ], linking both to disruptions in BBB permeability [ 44 , 109 , 111 , 112 , 113 ]. Intriguingly, similar patterns of neurovascular dysfunction are apparent in neurodegenerative diseases, such as AD, dementia, and PD [ 100 ].…”
