Acquired Brain Injury
There is nothing mild about injuring your brain
Acquired Brain Injury (ABI) can be broken into two categories:
Traumatic Brain Injury (TBI)
- Motor Vehicle Accidents
- Workplace injuries
Non-Traumatic Brain Injury
- Infection (i.e. meningitis, malaria, encephalitis)
- Anoxia/Hypoxia (i.e. heart attack, drowning, carbon monoxide poisoning)
- Toxic drugs or chemicals
Statistics show that 160,000 Canadians will experience a brain injury each year. (Braininjurycanada.ca, 2017). According to the Canadian Institute for Health Research:
- Traumatic Brain Injury is the key cause of disability in individuals under the age of 45
- Two-thirds of mild traumatic brain injuries occur in males
- Traumatic Brain Injuries are most common in the young and the elderly
- There is increasing evidence that multiple mild TBIs may pre-dispose to early onset dementia, later substance-use disorders and mental illness
Vision is the most pervasive sense in the brain. In fact, 35 areas of the brain are primarily or totally involved with the processing of visual information and there are at least 305 intra-cortical pathways that link these 35 areas. Furthermore, 65% of the sensory information to the brain is visual and there are more areas of the brain dedicated to vision than all the other sense modalities combined.
Any disruptions or disturbances to any of these 35 areas of the brain or any of these 305 intra-cortical connections can have a negative effect on vision and result in symptoms such as, but not limited to, light sensitivity, blurry vision, double vision, tired/aching eyes, headaches worsening with visual tasks, visual field loss, fatigue, difficulty reading, comprehension difficulty, difficulty with memory, and difficulty with attention.
Optometric Vision Rehabilitation can resolve many of the effects of Acquired Brain Injury. Individuals do not need to live with these symptoms. Optometric Vision Rehabilitation includes many different treatment options such as lenses, prisms, filters, overlays, and vision therapy.
