Considering that TBI is most frequently observed in the young adult age group, it presents considerable socioeconomic impact on the economically active population. In spite of the developments in the diagnosis and treatment of TBI, the figures are still staggering, because of the scarcity of public policies aimed at reducing the incidence of accidents. In Rio de Janeiro, over the past two to three years, we have been observing the effects of the anti-alcohol abuse law. The results have been encouraging, demonstrating that sound public policies may bring about cultural changes with positive impact on the society as a whole.

As previously reported in the literature, the most severe lesions were most frequently demonstrated in those patients presenting lower Glasgow coma scores at the moment of the examination. Additionally, the authors demonstrated a significant correlation between tomographic findings
