The symptoms of cerebral hemorrhage after head collision are as follows: 1. Headache: Head trauma itself can cause pain, and headache can be caused by stimulation of the meninges after bleeding, occupying effect of the hematoma, and elevated cranial pressure. 2. Positive meningeal stimulation sign: Patients with cerebral hemorrhage caused by trauma will have cerebral contusions, and blood will enter the subarachnoid space, causing positive meningeal stimulation sign, which is manifested by cervical tonicity, positive Kirsch’s sign and positive Brønsted’s sign. 3. 3. Focal neurological deficits: The occurrence of this symptom is related to the specific site of brain hemorrhage. If it is frontal lobe injury, there will be ataxia, mental disorder, and motor aphasia. If it is a temporal lobe injury, there will be mental disorders, cognitive impairment, seizures, and sensory aphasia. If it is an occipital lobe injury, there will be visual impairment, and if it is a cerebellar injury, there is often dizziness and ataxia.
