Traumatic brain injury lambert fick genote anoxia meaning

Acquired brain injury can come in many forms. Below are some common diagnoses:

– traumatic brain injury

– mild acquired brain injury

– mild closed head injury

– post-concussive syndrome

– cervical trauma syndrome

– post traumatic vision syndrome

– stroke

– cerebral palsy

– cerebral vascular accident

Essentially, acquired brain injury is an insult to the brain. It can result from a blow to the head, stroke, or neurological dysfunction. This can produce a diminished or altered state of consciousness, and may result in im­pairment of cognitive abilities, sensory proc­essing and/or physical function. Impairments may be mild or severe; most are amenable to rehabilitation. Specific effects can be:

– disturbance of behavioural or emotional functioning

anoxia meaning

– partial or total functional disability

– physiological maladjustment

– visual dysfunction


Often, visual problems resulting from acquired brain injury are overlooked during initial treatment of the injury. Fre­quently these problems are hidden and ne­glected, lengthening and impairing rehabilitation.

Vision is the most important source of sen­sory information. Consisting of a sophisti­cated complex of subsystems, the visual process involves the flow and processing of information to the brain. Because there is a close relationship between vision and the brain, acquired brain injury can disrupt the visual process, interfering with the flow and processing of information. The result is a vi­sion problem.Anoxia meaning symptoms indicating a vision problem are:

– blurred vision

– sensitivity to light

– reading difficulties; words appear to move

– comprehension difficulty

– attention and concentration difficulty

– memory difficulty

– double vision

– aching eyes

– headaches with visual tasks

– loss of visual field GOOD VISUAL SKILLS GOOD VISION

Good visual skills are necessary for effi­cient information processing. When processing visual information is difficult, one may “try harder,” straining without even knowing it because the effort is subcon­scious. If the visual system is inefficient, every task can seem difficult, using more energy than required. Visual skills affected by acquired brain injury include:

Tracking – the ability of the eyes to move smoothly across a printed page or while fol­lowing a moving object.Anoxia meaning

Fixation – quickly and accurately locating and inspecting a series of stationary objects, such as words while reading.

Focus change – looking quickly from far to near and back without blur.

Depth perception – judging relative dis­tances of objects-how far or near they are.

Peripheral vision – monitoring and interpret­ing what is happening in the surrounding field of vision.

Binocularity – using both eyes together as a team-smoothly, equally and accurately.

Maintaining attention – keeping focused on a particular activity while interference, such as noise, is present.

Visualization – accurately picturing images in the “mind’s eye,” retaining and storing them for future recall.

Near vision acuity – clearly seeing, inspect­ing, identifying and understanding objects viewed within arm’s length.Anoxia meaning

Distance acuity – clearly seeing, inspecting, identifying and understanding objects viewed at a distance.

Vision perception – understanding what is seen. OPTOMETRY AND REHABILITATION

Very few in the health care professions, including head trauma rehabilitation centers, are adequately aware of visual prob­lems resulting from acquired brain injury and the visual-perceptual consequences. Un­fortunately, this creates a gap in rehabilitative services, resulting in incomplete treatment and frustration for the patient, family and treatment team.

The vision care professional can play an im­portant role in the rehabilitation effort. Through vision therapy and the proper use of lenses, a behavioural optometrist specifically trained to work with acquired brain injury patients can help improve the flow and proc­essing of information between the eyes and the brain.Anoxia meaning

Vision therapy can be very practical and ef­fective. After evaluation, examination and consultation, the optometrist determines how a person processes information after an injury and where that person’s strengths and weak­nesses lie. The optometrist then prescribes a treatment regimen incorporating lenses, prisms, low vision aides and specific activi­ties designed to improve control of a person’s visual system and increase vision efficiency. This in turn can help support many other ac­tivities in daily living.
