Postconcussion syndrome and mild head injury: the role of early diagnosis using neuropsychological tests and functional magnetic resonance/spectroscopy.

Objective: Postconcussion syndrome (PCS) is usually underestimated in cases of mild head injury (MHI). It is one of the most common causes of physical, cognitive, and psychomotor disturbances that affect the quality of life, work, and social reintegration of individuals. Until now, we did not have evidence of structural abnormalities shown by traditional imaging methods.
