Minor head injury

In India about one million people sustain head injury every year. Minor head injury constitutes about 80 - 90% cases of total head injury patients. About 50% minor head injury cases have associated organic brain dysfunctions. Studies like SPECT, VEP, BAER, TCD and P300 recordings have demonstrated hypoperfusion and dysfunctional abnormalities of brain parenchyma in most of the cases having post-concussion syndrome and persistent post-concussion syndrome. Significant blood flow abnormalities are found in medial temporal lobe, hippocampus and frontal lobe etc, which are responsible for various functional problems.
