Patients with concussion often exhibit signs of transient consciousness disorders and recent memory loss after injury. Some patients may experience varying degrees of headache, dizziness, nausea, vomiting, blindness, and other clinical symptoms. If a patient with concussion experiences dizziness, the first step is to rule out the possibility of intracranial organic lesions through examination of the head and body. Then, the patient should rest in bed in a quiet environment with dim lighting. Additionally, symptomatic treatment with medications, including some that expand cerebral blood vessels, can be administered.
