The goal of this observational study is to learn about the impact of dexamethasone treatment in traumatic brain injury patients with vasogenic edema in the second week after the trauma, administered in centers where this intervention has been considered to treat brain edema. The main question it aims to answer is: Does dexamethasone in a regimen of 8mg/8h for 5 days improve vasogenic edema in patients after 5 days of their trauma? Participants already receiving this treatment as part of their regular medical care in emergency settings, general wards, or ICU settings for TBI will be included, and data will be compared with patients with the same criteria but who do not receive the treatment.
