What are the symptoms of a TBI?

Symptoms of traumatic brain injuries vary depending on the type and severity of the injury. Mild brain injuries, also known as concussions, can cause symptoms such as headache, nausea/vomiting, dizziness, mild confusion, sensitivity to light/sound, and altered senses such as double vision or ringing in the ears. Moderate to severe traumatic brain injury can cause more severe symptoms, including loss of consciousness, persistent vomiting, convulsions/seizures, clear fluids draining from the nose or ears, loss of coordination, profound confusion, slurred speech, and weakness or numbness in hands and feet.
