query: Can you prevent traumatic brain injury?
passage: Traumatic brain injury
Prevention measures include use of protective technology in vehicles, such as seat belts and sports or motorcycle helmets, as well as efforts to reduce the number of collisions, such as safety education programs and enforcement of traffic laws. Depending on the injury, treatment required may be minimal or may include interventions such as medications, emergency surgery or surgery years later. Physical therapy, speech therapy, recreation therapy, occupational therapy and vision therapy may be employed for rehabilitation. Counseling, supported employment, and community support services may also be useful.
passage: Neural stem cell
Traumatic brain injury (TBI) can deform the brain tissue, leading to necrosis primary damage which can then cascade and activate secondary damage such as excitotoxicity, inflammation, ischemia, and the breakdown of the blood-brain-barrier. Damage can escalate and eventually lead to apoptosis or cell death. Current treatments focus on preventing further damage by stabilizing bleeding, decreasing intracranial pressure and inflammation, and inhibiting pro-apoptoic cascades. In order to repair TBI damage, an upcoming therapeutic option involves the use of NSCs derived from the embryonic peri-ventricular region. Stem cells can be cultured in a favorable 3-dimensional, low cytotoxic environment, a hydrogel, that will increase NSC survival when injected into TBI patients. The intracerebrally injected, primed NSCs were seen to migrate to damaged tissue and differentiate into oligodendrocytes or neuronal cells that secreted neuroprotective factors.
