CC | Diffuse Axonal Injury (DAI)

According to your sources, Diffuse Axonal Injury (DAI) is widespread axonal damage caused by the physical forces of a mild, moderate, or severe traumatic brain injury (TBI)[1].Physical MechanismTraumatic Impact Forces: DAI occurs due to the tensile forces of trauma sustained during a head injury[1].Cellular Progression: Rather than immediate shearing or tearing of the axon at the moment of impact, the trauma alters axonal functioning[1]. This leads to progressive axonal swelling and disconnection over a 12- to 24-hour period (or longer)[1].Common Causes of Head Injuries & TBIsBecause DAI is a generalized form of TBI resulting from traumatic impact, it stems from the common causes of head trauma[1][2]:Motor vehicle accidents (most common)[2]Falls (most common)[2]Sports-related trauma[2]Assaults[2]Firearms[2]Recreational injuries[2]War-related injuries
