hi jake

anxiety attacks are not a symptom of pcs in all cases but the general low mood and fogginess could trigger an episode especially if you have suffered in the past if your sleep patterns are out of sync that can also play a part go see your doctor to talk through your options please don,t get PCS mixed up with TBI we share this board so it can happen PCS is disruption of brain function TBI is brain injury you can also help in the healing process by keeping your self hydrated and taking good multi vitamins and most of all taking omega 3 and omega 6 fatty acid,s rest and no more bangs to the head keep going back to the doctor if you are worried keep us posted

kind regards vini
