What Is Post-Concussion Syndrome?
Post-Concussion Syndrome is a group of ongoing symptoms that can follow a concussion, even after the initial head injury has healed. Symptoms may include headaches, dizziness, fatigue, sleep changes, sensitivity to light or sound, and difficulty concentrating. The condition can affect daily activities and may require evaluation of several body systems.

How Post-Concussion Syndrome Works

Post-Concussion Syndrome describes symptoms that remain after a concussion. The symptoms can involve the head, balance, vision, sleep, mood, or thinking. A person may notice headaches during activity, dizziness when changing position, or trouble focusing during ordinary tasks. The pattern can vary from person to person.

Evaluation considers the reported symptoms, the injury history, and changes in daily function. A clinician may also examine balance, eye movement, neck motion, and other physical findings. Concussion refers to the original brain injury, while Post-Concussion Syndrome describes symptoms that continue afterward. Vestibular System concerns balance and spatial orientation, so vestibular symptoms may appear as dizziness or unsteadiness.
