For most patients, post concussion symptoms go away within a few days to several weeks after the original injury occurs.[In others, symptoms may remain for three to six months.In a small percentage of patients, symptoms may persist for years or may be permanent.
One of the most common misunderstandings is the difference between concussion and post-concussion syndrome. Concussion is a short-term injury that does go away. Lasts couple days to 2 weeks, at most. Symptoms that go on beyond that are most likely Post-Concussion Syndrome (PCS.) PCS is not a long concussion. Post-concussion syndrome is sometimes thought to be a âlong concussion,â however that is not the case. Post-concussion syndrome is a complex disorder with varying symptoms. Patients with post-concussion syndrome have experienced a concussion before there is a continuation of symptoms for another reason. Post- concussion syndrome symptoms can occur within days of the concussion being over, weeks or even persist greater than a year. Our Approach One of the most common problems we see is that patients are given up on when they have post-concussion syndrome.
