Concussion

Any physical or traumatic injury or blow to the head causes a concussion of the brain. A sudden movement of the brain within the cranial vault due to trauma can alter the mental state and even lead to an unconscious state. Though concussions are not serious, they cause symptoms that require medical attention. Loss of consciousness, memory loss, sensitivity to light and sound, behavioral changes, imbalance, confusion, dizziness, blurred vision, slurred speech, headache, etc., are all some signs and symptoms of concussion. Seek immediate medical help when the symptoms are prolonged.
