Post Concussion Syndrome is a cluster of symptoms that follow a known impact to the head. The individual matrix of symptoms effecting any one individual will be different. As the saying goes, "If you've seen one brain injury, you've seen one brain injury." Some will claim it does not become PCS until it last beyond a week or two to even a month. That time line varies.

There is a new category of PCS called PPCS or Prolonged Post Concussion Syndrome. This is when symptoms persist into a longer period of a year or two, again, the time line is not specifically established.

One expert suggests all impacts to the head be recorded in the patients medical records so that later manifestation of symptoms can be considered as possible PCS. Without this possible concussion in the medical record, the cluster of PCS symptoms can be confusing to the doctor and patient leading to errant diagnoses.

The following International Code of Diagnostics are recommended for the patients' medical record.

A violent jar or shock, or the condition which results from such an injury.
