Concussion is a type of mild traumatic brain injury associated with a head injury such as hit to the head post fall or blow to the head. It occurs when the blow to the head is strong enough to cause violent head movement. Brain injury associated with concussion causes the brain to move suddenly and abruptly inside the cranial vault. Concussion often results in short term brain dysfunctioning. It is a serious injury which affects the normal functioning of the body and brain cells.

How Long Does a Concussion Last?

The symptoms associated with concussion can last anywhere from a few days to a couple of months. The duration of the condition depends on the severity of the brain injury involved. Based on the severity and duration of the symptoms, concussions are graded as discussed below:


  • Grade 0: Associated with headache and difficulty with concentration and focussing.
  • Grade 1: This type of concussion is associated with headache, difficulty with concentration with a feeling of being dazed for less than a minute.
  • Grade 2: Symptoms are similar to grade 1, but with a longer period of feeling dazed. Other symptoms include amnesia, dizziness, ringing in the ears, confusion and generalized irritability.
  • Grade 3 Concussion: Associated with loss of consciousness that lasts for less than a minute.
  • Grade 4 Concussion: Associated with loss of consciousness which lasts for longer than a minute.

In patients with grade 0 or grade 1 concussion, resuming limited activities may be allowed within a day or two. However, patients with grade 2 concussion requires longer period of rest (around 5 to 7 days). In cases of grade 3 or grade 4 concussions, the patients need a few weeks of rest for recovery. Regardless of the grade of concussion that the patient may be suffering from, it is important to ensure that the patient is completely symptom free before resuming his or her normal life.

  • Cause of the injury
  • Severity of the concussion (Mild, moderate or severe)
  • Delay in treatment or medical attention
  • Type of treatment received and response to the treatment
  • History of previous concussion or brain injury
  • Presence of other underlying medical condition.
