A person with a concussion may experience certain symptoms including passing out, confusion, headache, dizziness, general body weakness, slurred speech and nausea. The signs and symptoms may vary from one individual to another depending on the intensity of the injury. Some symptoms may last for a short time while others may last for weeks, according to Mayo Clinic.
A concussion is an injury to the brain that is caused by some sort of impact to the head or other part of the body, as defined by WebMD. Such injuries may be caused by a variety of incidents, including car accidents, falling down the stairs, being hit by a falling object or being attacked.
People who suffer from severe concussions may end up suffering from amnesia or a loss of memory. This means the individual is not able to remember events that take place right after the impact. The individual may also continue experiencing headaches as the concussion heals.
Other commonly experienced symptoms include vomiting and an appearance of confusion. The individual may have a difficult time responding to questions and may have slurred speech for a given period of time. Although not common, some individuals may develop a sensitivity to light and may experience sleep disturbances. Attending a medical check-up and getting plenty of rest is the key to a quick recovery after a concussion.
