Some primary pathophysiological events may trigger secondary brain injury over time. Not all brain injuries are the same; they differ from their severity. The secondary injury can happen from minutes to days from the primary impact and consists of a molecular, chemical, and inflammatory cascade responsible for further cerebral damage. Any damage the brain sustains is likely to result in two types of symptoms: primary brain damage and secondary brain damage. Secondary brain injuries follow on from a primary injury and can include swelling of brain tissue or bleeding from blood vessels in the brain.

Secondary cell death mechanisms, including excitotoxicity, oxidative stress, mitochondrial dysfunction, blood-brain barrier disruption, and inflammation accompany chronic traumatic brain injury (TBI) and often contribute to long-term disabilities. Swelling of the brain and increased pressure inside of the skull Secondary injury can occur minutes, hours, days or even weeks after the initial injury and the damage can be averted or lessened by appropriate clinical management.

Primary Brain Injury - Direct trauma to the brain and associated structures (Contusions, hemorrhages, lacerations) Secondary Brain Injury - The ongoing injury process from primary injury - Management of TBI is focused to limit or stop these secondary mechanisms (ICP, hypoxia, hypotension and inadequate cerebral blood flow) Mild TBI A patient can also experience extreme fatigue and insomnia. Types of Secondary Brain Injury.
