When the head receives a sharp blow by an external force, the movement between the brain and the skull can produce a cerebral concussion – a mild traumatic brain injury (mTBI).  The frontal and temporal lobes of the brain are the most susceptible to these types of injuries.  Postconcussional Disorder is the diagnosis that describes the specific set of neuropsychological symptoms that can persist after experiencing a concussion.  The physical, cognitive, and emotional/behavioral symptoms that often accompany a mild traumatic brain injury may persist for weeks to years after the initial injury has occurred.  A mild TBI can also exist without any external evidence of physical injury or trauma.  The manifestations of a mild TBI can appear after loss of consciousness, brief loss of memory, or feeling of being dazed or seeing stars is experienced.
