The most common initial symptoms after suffering a concussion are headache, dizziness and fatigue. However, other secondary symptoms often develop afterwards that affect emotional status and cognitive ability. The time course of these symptoms can be debilitating for students. According to a study involving almost 300 students between the ages of 11 to 22 years, one week after injury:
• more than two-thirds still suffered from headache
• a majority still complained about poor concentration, dizziness, fatigue and taking longer to think
• more than 40% still struggled with forgetfulness, light sensitivity and noise sensitivity.
Various studies have shown that eye movements are intimately affected post-concussion. Research also shows that improving eye movements will help improve concussion symptoms. A study involving college athletes even showed that improving eye movements helped reduce the incidence of concussions.

Up to 90% of people who have suffered a MILD TRAUMATIC BRAIN INJURY report having subsequent READING PROBLEMS. After the concussion, 90% of these people have fine eye movement problems, 40% have difficulties properly focusing their eyes and 50% report light sensitivity. These visual problems will adversely affect: 1. ability to scan across a sentence, 2. ability to keep words clear and accurate, 3. comfort while reading and 4. maximum reading duration. Returning to normal daily activities can be severely hindered by post-concussion reading problems. Visual skills therapy has been shown to provide long-term relief to the above symptoms.

Poor EYESIGHT is associated with increased odds of DEMENTIA according to two large-scale studies in the U.S. Poor distance or near eyesight was associated with approximately a 2 to 2.5 times greater likelihood of dementia. The findings “highlight the importance of timely detection of visual impairment in the elderly population” per the studies’ authors. If you, or someone you know, is in the aging population, please make eyesight a priority. Vision problems are significantly associated with decreased cognitive function and senile dementia.

Vision training improves concussion symptoms in up to 90% of cases according to research. Headaches, blurred vision, double vision, dizziness, balance problems, light and noise sensitivity, eye fatigue, and loss of place with reading and close work are common visual symptoms after a concussion. We have helped a number of people with these symptoms. If you know of someone who is suffering from the effects of a concussion, please let them know that we can help.
In patients suffering from post-concussion symptoms, studies show that their brain wave function is scattered. Instead of using the typical parts of the brain for a specific task like they would before the injury, post-concussion patients use many parts of the brain that are not normally used for that job to try to accomplish the task. This is a reason why some patients find it difficult to concentrate on tasks after a head injury. In addition, the speed at which these patients process information is significantly slower than before the injury occurred. These same studies reveal that optometric vision rehabilitation helps the brain wave function of these post-concussion patients be more focused. Instead of using unrelated, scattered parts of the brain for a typical task, patients who have received optometric vision rehabilitation are able to utilize the parts of their brain that would typically be engaged in that task. Also, the processing speed for these patients improve after rehabilitation. Treatment for visual deficits is not a cure-all for someone with widespread neurological damage after traumatic brain injury. However, evidence suggests that optometric vision rehabilitation can positively influence brain function.
Visual symptoms are commonly experienced after a head injury. Even though post-injury eyesight can often be corrected to 20/20, many patients may still experience vague visual discomfort and difficulty reading or concentrating. Common visual complaints include seeing double, seeing stationary objects exhibit movement, seeing words and print run together, experiencing intermittent blur and experiencing light sensitivity. Other people may also suffer from what seems to be floors that are tilting, difficulties with balance and orientation in a crowded environment and changes in posture and gait. However, these people who are experiencing these visual difficulties may often have healthy eyes and normal eyesight. If you or someone that you know is experiencing these symptoms after suffering a head injury or cerebrovascular event, please call for a full visual evaluation. A yearly eye exam will not be able to uncover parts of the visual system that may be contributing to your difficulties.
