epidural has more mass effect on the brain.
Acute epidural hematoma occurs with modest trauma to the side of the head.Emergency craniotomy produces dramatic cure.
Acute subdural hematoma has the same sequence, but the trauma is much bigger, the patient is usually much sicker (not fully awake and asymptomatic at any point), and the neurologic damage is severe (because of the initial blow). If midline structures are deviated, craniotomy will help, but prognosis is bad. If there is no deviation, therapy is centered on preventing further damage from subsequent increased ICP.
Chronic subdural hematoma occurs in the very old or in severe alcoholics. A shrunken brain
is rattled around the head by minor trauma, tearing venous sinuses. Over several days or weeks,mental function deteriorates as hematoma forms.
