Hello, As per the information provided by you and the history of concussion, the symptoms are possibly related to your history. But you should also rule out any disorder related to your eyes. Please get your ophthalmological testing including that of retina done. Because there could be the possibility that whole or part of the symptoms experienced by you are due to that. But post-concussion syndrome as the primary differential diagnosis, need to be discussed here in detail. First of all, I want to assure you that the after effects to concussion or head injury tend to fade away as the time passes. For its management and better prognosis you can try following: 1)     Exercise: It helps to maximize blood flow to the brain that will help in early recovery. But try to work with a specialist to set stop points for you. 2)     Due to injury to any tissue, there is inflammation; concussions are no exception with several studies demonstrating increased inflammatory markers following injury to the brain. Concussion results in a metabolic dysfunction, which is why rest is important early on; anything that burns energy, such as thinking or physical activity, can increase symptoms as is evident from your case. Treatment options for these things include simple dietary changes such as avoiding pro-inflammatory foods (red meats, refined sugars, white breads and pastas, artificial sweeteners) and replacing them with healthier options such as fruits and vegetables, fiber-rich food, fresh caught fish (salmon, mackerel, herring), and good fats (coconut oil, flaxseed, almonds). These changes may help to offset an ongoing inflammatory response and reduce your symptoms. 3)     Dizziness is one of the most common ongoing complaints of patients with persistent symptoms. This may be due to a number of overlapping issues such as problems with the balance centres of your brain, your visual system, and/or problems with the muscle and joint sensors of your neck. Visual system problems may also be one of the causes of ongoing cognitive complaints such as trouble with concentration. Hence, you are suggested to avoid such triggering factors that are well known to you as well as evident in the information provided by you. This is the best method for its management. Also, try to do eye strengthening exercises that may help to provide strength to the eye muscles. In some unavoidable circumstances, you can take medications like Meclizine, Scopolamine, Dimenhydrinate, lorazepam or diazepam to combat dizziness. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Maninder, General & Family Physician
