Every brain injury is different and there are a wide range of symptoms that a victim can suffer from when they experience trauma or lack of oxygen to the brain. Some common symptoms include disorientation, headaches, nausea or vomiting, fatigue, dizziness, memory and concentration problems and mood changes. In very severe cases, symptoms may range from profound confusion, agitation and combativeness to seizures, comas or other consciousness disorders. If a person suffers any symptoms after an accident or other trauma to the brain, they should seek immediate medical treatment. A physician can fully evaluate your injuries and order the proper tests and procedures to properly diagnose your condition. After you or a loved one has received appropriate medical attention, you should consult with a Miami brain injury lawyer who can review your case to discuss the legal courses of action that may be available to you.
