Individuals with extradural hematomas lose consciousness at injury; one-third then become lucid for a few minutes to a few days.
Mild concussion is characterized by immediate but transitory confusion that lasts for one to several minutes,possibly with amnesia for events preceding the trauma.
Subdural hematomas begin with headache,drowsiness,restlessness or agitation,slowed cognition,and confusion.These symptoms worsen over time and progress to loss of consciousness,respiratory pattern changes,and pupillary dilation.
Individuals with mild diffuse axonal injury display decerebrate or decorticate posturing and may experience prolonged periods of stupor or restlessness.
