Head Injury Symptoms

Signs and symptoms of head injuries vary with the type and severity of the injury.

• Minor blunt head injuries may involve only symptoms of being "dazed" or brief loss of consciousness. They may result in headaches or blurring of vision or nausea and vomiting.
  
  
• Severe blunt head trauma involves a loss of consciousness lasting from several minutes to many days or longer. Seizures may result. The person may suffer from severe and sometimes permanent neurological deficits or may die. Neurological deficits from head trauma resemble those seen in stroke and include paralysis, seizures, difficulty speaking, seeing, hearing, walking, or understanding.
  
  
• Penetrating trauma may cause immediate, severe symptoms or only minor symptoms despite a potentially life-threatening injury. Death may follow from the initial injury. Any of the signs of serious blunt head trauma may result.
