Symptoms include headache, dizziness, photophobia, phonophobia, tinnitus, difficulty concentrating, short-term memory problems, depression, anxiety, irritability, insomnia, and fatigue.
The severity of the head injury does not clearly correlate with the risk of developing postconcussion syndrome. Most patients recover within 6 months after injury, although symptoms can persist for a year or more in some cases.
