Sometimes, people call concussions a “minor” brain injury. It is important to understand that, although concussions would not put life at risk, they can be serious.
Concussions are a common type of sports injury . Other causes include blows to the head, hitting the head after a fall, being shaken violently or traffic accidents. Symptoms may not show up right away. They can start days or weeks after the injury. Symptoms may include headache or neck pain. You may also have nausea, ringing in the ears, dizziness or tiredness. You may feel dizzy or not feel well for several days or weeks after the injury. Consult your health care provider if some of your symptoms get worse or if you have more severe symptoms, such as:
Drowsiness or difficulty walking or sleeping
Headache that gets worse and does not get better
Weakness, numbness or decreased coordination
Vomiting or frequent nausea
Loss of consciousness
To diagnose a concussion, your health care provider will examine you and ask about your injury. You are likely to undergo a neurological exam that will check your vision, balance, coordination and reflexes. Your provider will also evaluate your memory and thinking. In some cases, you may have a brain scan, such as a CT scan or magnetic resonance imaging . This test may look for signs of bleeding or swelling of the brain, as well as fractures of the skull.
Most people recover completely after a concussion, but it may take some time. Rest is very important, because it helps the brain to heal. At the beginning it may be necessary to limit physical activity or tasks that require concentration, such as studying, working on the computer or playing video games. These activities can cause the symptoms of a concussion (such as headaches or exhaustion) to return or worsen. Once your health provider tells you that it is okay, you can resume your normal activities slowly.
The lightheadedness is the feeling that you are about to faint or “pass out “. Although you may feel dizzy, you do not feel as if you or your surroundings are moving.
Stunning usually disappears or improves when lying down. If the stunner gets worse, it may produce a feeling that you are about to faint or a fainting episode ( syncope ). You may feel nauseated or vomit when you are stunned.
Vertigo is the feeling that you or your environment are moving when, in reality, no movement occurs. You may feel as if you are losing your balance, spinning, rotating, falling or bending. When you have severe vertigo , you may feel very sick or vomit. You may have trouble walking or standing, and you may lose balance and fall.
Although dizziness can occur in people of any age, they are more common in older adults. Fear of dizziness can cause older adults to limit their physical and social activities. Dizziness can also cause falls and other injuries.
It is common to feel dazed from time to time. Short episodes of stunning are not usually a consequence of a serious problem. Stunning is usually caused by a momentary decrease in blood pressure and blood flow to the head that occurs when standing up too quickly after sitting or lying down ( orthostatic hypotension ). A constant daze may mean that you have a more serious problem that needs to be evaluated.
Stunning has many causes, including:
Diseases like flu or colds. In general, home treatment of flu and cold symptoms will relieve the stun.
Vomiting, diarrhea, fever and other diseases that cause dehydration .
Very rapid or deep breathing ( hyperventilation ).
Anxiety and stress .
The use of tobacco, alcohol or illegal drugs.
A more serious cause of the stun is bleeding. Most of the time, the location of the bleeding and the need to seek medical attention are obvious. But, sometimes, the bleeding is not obvious (hidden bleeding). You may have small amounts of bleeding in the digestive tract for days or weeks without noticing the bleeding. When this occurs, stunning and fatigue may be the first notorious symptoms that you are losing blood. Heavy menstrual bleeding can also cause this type of stun.
Sometimes, the cause of the stun is an abnormal heart rhythm ( arrhythmia ), which can cause fainting (syncope). Fainting of unknown origin should be evaluated by a doctor. You can control your heart rate by taking your pulse .
Many drugs prescription and nonprescription medications can cause lightheadedness or dizziness. The degree of stunning or dizziness that a medication causes varies.
