Abstract: The evidence and the feature of apoptosis following tyrauma brain injury(TBI) and the possible mechanisms underlying apoptosis were reviewed. Recently research showed that apoptosis play an important role in TBI, the occurring time and area of apoptosis were found significant differences compared with that of necrosis. The neural cell apoptosis can undergo following many pathways after TBI. In our review, the foreground of apoptosis after TBI research in forensic pathology were also discussed.

Key words: brain injury, apoptosis, pathogenesis
