Rollerblading is an international phenomenon! But it is not without risk. I personally know several professionals who suffered a traumatic brain injury (TBI) while rollerblading without a helmet. As a result, they have cognitive and executive function deficiencies that keep them from working. They have great trouble concentrating, following multi-step directions and managing their time efficiently. They cannot process information quickly and take much longer to complete simple tasks. These are people who functioned at a very high professional level. Understandably, they are frustrated and depressed by their limitations. One of the difficulties that they have in trying to get disability benefits is that they “look fine”. TBI is not an injury that you can see with the naked eye. It does not cause scars or deformities. It does not show up on an x-ray. The key to getting Social Security disability benefits for TBI patients is to prove, through medical evidence, cognitive limitations and how those limitations interfere with day-to-day activities.
