What is a concussion?

Concussion is the most common type of brain trauma and also the mildest. On a more technical level the expression refers to a small loss of knowledge that does not last long and which can happen after receiving an impact to the head, due to an injury or after a movement in which the head and brain move back and forth very quickly.


Although as a rule, a concussion does not have to be mortal, it is can cause a series of symptoms of considerable importance , which should be treated with all possible haste.

Also, this type of trauma can cause neuronal imbalances without the need for an apparent structural lesion. After a brain seizure of this type the brain is briefly blocked, may present loss of consciousness, confusion or alterations in memory .

The fact that it is one of the most common brain accidents is because of the ease with which it can occur, since any fall, car accident, or any sport or daily activity that involves a lot of movement makes the person susceptible to suffer a concussion.

Symptoms of concussion

The symptoms associated with the concussion vary according to the person who suffers it and according to the severity of the injury. For example, although the loss of knowledge is a very common symptom of concussion, not all people who suffer from it fail.

In the same way, it is possible for the person to experience the following symptoms both immediately and after a few hours, or even days and weeks, after the accident.

Symptoms of concussion can be classified into three types : mild concussion symptoms, severe symptoms and symptoms that appear during the recovery process.

Considerable movement of the brain in any direction or direction can result in a loss of consciousness for the person. Depending on the duration of this loss of consciousness, the severity of the concussion will be greater or lesser.

However, a commotion it does not always lead to a faint , there are people who experience an alteration in the visual perception that makes them see everything black or white.In the same way, a person may suffer a mild concussion and not be aware of it, since he does not experience any symptoms or, if he does, it is so mild that he does not associate it.

Then, It is necessary to perform a physical examination to check the state of the nervous system . This exploration includes the evaluation of reflexes, variations in the size of the pupils, coordination and mental lucidity.

Finally, and according to the patient's state of seriousness, they will be a series of tests and diagnostic tests . These tests include:

  • Computed tomography (CT).
  • Magnetic resonance (IMR).
  • Electroencephalogram (EEG) in cases in which seizures persist.

Multiple concussion

After suffering a first concussion, and if the instructions of the health personnel are not followed or some type of sport or physical activity is carried out, the person is susceptible to suffer a second concussion.
