Cerebral amyloid-ß accumulation and deposition following traumatic brain injury-A narrative review and meta-analysis of animal studies
MetadataShow full item record
Traumatic brain injury (TBI), increases the risk of neurodegenerative disorders many years post-injury. However, molecular mechanisms underlying the relationship between TBI and neurodegenerative diseases, such as Alzheimer's disease (AD), remain to be elucidated. Nevertheless, previous studies have demonstrated a link between TBI and increased amyloid-ß (Aß), a protein involved in AD pathogenesis. Here, we review animal studies that measured Aß levels following TBI. In addition, from a pool of initially identified 1209 published papers, we examined data from 19 eligible animal model studies using a meta-analytic approach. We found an acute increase in cerebral Aß levels ranging from 24h to one month following TBI (overall log OR=2.97±0.40, p<0.001). These findings may contribute to further understanding the relationship between TBI and future dementia risk. The methodological inconsistencies of the studies discussed in this review suggest the need for improved and more standardised data collection and study design, in order to properly elucidate the role of TBI in the expression and accumulation of Aß.
