Physiological Problems After A Concussion May Last Longer Than Standard Symptoms

The standard symptoms of a concussion include headache, confusion, disorientation, memory loss, and poor concentration. Patients who suffer from a concussion are usually tested and re-tested for these abilities in order to determine the level of recovery. Complete recovery is usually expected within two weeks after the injury.

However, recent research using motor-provoked potentials found that electrophysiological changes after a concussion continue even after the standard symptoms subside and the patient reports feeling better. In some cases, the electrophysiological changes increased even as the standard symptoms decreased and the patient's status improved.

The researchers of the study warned that using the standard measurements of recovery may result in concussed athletes returning to play too soon.
