Burn Injury as a Neurodegenerative Catalyst

Burn injuries, especially those that cover a wide area of the total body surface area (TBSA), cause a systemic reaction that goes beyond damage to the affected tissue. New research shows that severe burns can have a huge effect on the central nervous system (CNS). This suggests that burn damage may induce neurodegenerative processes. This chapter looks at several ways that burn injuries can start or make neurodegeneration worse. It focuses on systemic inflammatory response syndrome (SIRS), cytokine dysregulation, blood–brain barrier (BBB) disruption, oxidative stress, and microglial activation. These pathways lead to neuronal damage, myelin loss, synaptic dysfunction, and cognitive problems, which are all prominent signs of neurodegenerative disorders. The chapter compares changes in CNS after a burn injury to those seen in well-known conditions like Alzheimer’s disease, Parkinson’s disease, and traumatic brain injury (TBI). It points out important similarities and suggests that burn trauma may reveal hidden weaknesses or speed up the progression of disease. Understanding these links gives us important information about the long-term neurological effects of burns on survivors and points forth possible ways to preserve their brains.
