“The following facts and circumstances, among others, tend to establish the occurrence of a cerebral concussion followed by a postconcussion syndrome as a result of craniocerebral trauma: History of injury; Impaired consciousness immediately following injury; Amnesia for events preceding and following injury; Skin cold, clammy, pale; Vital signs normal, or nearly normal, immediately following injury; Neurological examination essentially normal; Return to normal consciousness; Complaints of headache and dizziness on recovery of consciousness; Prompt improvement with no signs of increasing intracranial pressure; Appearance of postconcussion symptoms; Appearance of minor neurological changes; Diagnosis, postconcussion syndrome; Accident as cause of postconcussion syndrome, physician’s opinion; Treatment; Prognosis. The symptoms and signs of concussion and the postconcussion syndrome vary from patient to patient and with the presence or absence of other injuries.”
