Post-concussion Syndrome

Post-concussion syndrome is a group of symptoms which can develop in people who have suffered from concussion. The symptoms of this syndrome may include problems with concentration and memory, dizziness and headache. The symptoms normally disappear in approximately 3 months. No treatment is available which can cure this syndrome the aim is to relieve the symptoms.


Concussion is caused by an injury to the brain which can occur after an injury to the head. The brain moves a little in the skull. And this causes the electrical activity in some of the brain cells to briefly stop working as they should. This interference leads to concussion symptoms. Some doctors categorize concussion as a minor injury to the brain.

Classic symptoms of concussion are confusion, headaches and memory loss at the time of the injury to the head. Loss of consciousness, disturbed vision and vomiting are other symptoms.

Making a Diagnosis

The doctor will diagnose post-concussion syndrome based on the symptoms you have. A physical examination may also be carried out. An examination of the nervous system will be carried out by testing the muscle reflexes, co-ordination, muscle strength in legs and arms. Tests of memory may be carried out. The doctor may organize a brain scan, e.g. MRI or CT scan to rule out any other injuries.
