The symptoms of a<unk>  have a slower onset than those of epidural<unk> s because the lower-pressure veins involved bleed more slowly than arteries. Signs and symptoms of acute<unk> s may appear in minutes, if not immediately, but can also be delayed as much as two weeks. Symptoms of chronic<unk> s are usually delayed more than three weeks after Injury. If the bleeds are large enough to put pressure on the brain, signs of increased intracranial pressure or brain damage will be present. Other symptoms of<unk>  can include any combination of the following: * Loss of consciousness or fluctuating levels of consciousness * Irritability * Seizures * Pain * Numbness * Headache (either constant or fluctuating) * Dizziness * Disorientation * Amnesia * Weakness or lethargy * Nausea or vomiting * Loss of appetite * Personality changes * Inability to speak or slurred speech * Ataxia, or difficulty walking * Loss of muscle control * Altered breathing patterns * Hearing loss or ringing in the ears (tinnitus) * Blurred vision * Deviated gaze, or abnormal movement of the eyes.
