Abstract
Traumatic brain injury (TBI) is one of the most prevalent causes of morbidity and mortality all over the world. More than 350,000 individuals are admitted each year as a result of TBI in the USA alone (Kraus et al., 1996). This disease affects mainly young adults in their productive stage of life, producing long lasting disabilities in 25% of cases. This represents an enormous social and economical cost estimated to be around 38 billion dollars per year in the USA (Max et al. 1990). However, at the present there is no available treatment to reduce the extent of cerebral damage following brain injury, other than supportive intensive care.
