What comes to mind when you think of the word “syndrome?” Many commonly known syndromes are often associated with genetic factors or medical diseases that are often lifelong or have lasting effects. Because we know that many post-concussion symptoms are treatable, Cognitive FX agrees with the recent change in terminology and diagnosis that replaced post-concussion syndrome with the more accurate title of post-concussion symptoms. What was post-concussion syndrome? According to the latest International Classification of Diseases (ICD-10), post-concussion syndrome included “subjective physical complaints (i.e. Headache, dizziness), cognitive, emotional, and behavioral changes. These disturbances can be chronic, permanent, or late emerging” (King, Crawford, Wenden, Moss, & Wade, 1995). More specifically, post-concussion syndrome referred to a cluster of problems that emerge or worsen after receiving a concussion, with symptoms lasting longer than three months.
