The brain is compacted by molding of the bone inward even if the skull is not fractured .the pressure on the brain at the time of the coup may force the brain to the opposite side of the skull which cause additional bruise and known as counter coup. The movement of the brain in the skull may cause shearing and twisting of the nerve fiber s producing the Microscopic lesion.

The close brain injuries usually followed by loss of consciousness. According to Lezak the duration of loss conciseness or the length of coma can use, as a measure of the severity of damage and it is correlate directly with mortality, intellectual impairment and deficit socia...
