Post-concussion syndrome
Though no universally accepted definition of postconcussive syndrome exists, most of the literature defines the syndrome as the development of at least 3 of the following symptoms: headache, dizziness, fatigue, irritability, impaired memory and concentration, insomnia, and lowered tolerance for noise and light. One complication in diagnosis is that symptoms of PCS also occur in people who have no history of head injury, but who have other medical and psychological complaints. In one study 64% of people with TBI, 11% of those with brain injuries, and 7% of those with other injuries met the DSM-IV criteria for post-concussion syndrome. Many of these PCS sufferers were misdiagnosed as having other unrelated conditions due to commonality of symptoms. (see diagnosis, below).
Harry Carson
Harry Carson authored his second book "Captain for Life" published by St. Martin's Press in 2011. In his book he documents his experiences with Post Concussion Syndrome. He was one of the first former professional athletes to share his own personal first hand experiences years before the long term effects of concussions and chronic traumatic encephalopathy (CTE), long before the subject became a "hot button" topic.
