Traumatic brain injury produces acute mechanical damage and a prolonged secondary phase in which cellular responses shape outcome. Astrocytes are prominent in both.

Acute and subacute roles
§ 2
Chronic consequences
Persistent astrocyte activation may contribute to post-concussive symptoms and long-term neurodegeneration in some patients.
