Focal Unilateral Traumatic brain injury Causes Delayed Neurodegenerative Changes in the Brain of Rats

A cascade of pathological changes in the intact hemisphere developed in rats 6 months after focal unilateral traumatic brain injury: neuronal degeneration, hyperexpression of α-synuclein, APP (β-amyloid peptide precursor) protein, and glutamine synthetase in cells other than astrocytes. The development of these changes in the contralateral hemisphere indicated the emergence of extensive delayed neurodegenerative processes in the brain after traumatic brain injury, which were characteristic of diseases associated with pathological aging.
