Neuroplasticity is the term used to describe the brain's ability to form neural connections in response to new information, sensory stimulation, development, dysfunction, or damage. In general neuroplasticity is often associated with learning that takes place during infancy. Research has shown that this type of change in neural connections takes place throughout a person's life. In short, neuroplasticity is the rewiring of the brain. The ability for the brain to form new neural connections in response to damage caused by a brain injury is the basis of Vision Restoration Therapy (VRT) . Vision Restoration Therapy is a daily method of stroke and traumatic brain injury rehabilitation that targets the visual center of the brain. Vision Restoration Therapy attempts to leverage the process of neuroplasticity through non-invasive light stimulation to this part of the brain. The therapy, performed on an FDA-cleared medical device, is customized for each patient's vision deficit and is updated on a monthly basis for optimal results.
Physical Changes
Neuroplasticity is a complex activity that can involve multiple levels of brain organization. It is also a physical process. Thinking, learning, and environmental stimuli actually change both the brain's physical structure, and functional organization. These physical changes in the brain translate to changes in our abilities - the ability to perform a new dance step, to recall the name of a new acquaintance, and so on. A recent neuro-imaging study using an fMRI - a type of specialized MRI scan used to study activity in the brain based on blood flow - showed changes in brain activity after VRT was performed. This study suggested that cerebral reorganization does occur1.
About Visual Neuroplasticity
People suffering from a variety of conditions like visual field defects may be able to stimulate their brains and restore proper function by undergoing neuroplasticity-based therapies. While neuroscientists have not yet uncovered the exact mechanisms of recovery, they have seen cortical reorganization or remapping in the brain through the use of fMRI. In response to stimulation, the formation of new neural connections in the visual cortex of the brain can bypass areas damaged by stroke or brain injury. NovaVision Vision Restoration Therapy uses customized therapy modules to provide the survivors of stroke and traumatic brain injury with effective vision rehabilitation.
Neuroplasticity-based Therapy for Vision Loss
Vision Restoration Therapy induces neuroplasticity by non-invasively stimulating the visual cortex of the brain through the retina to treat vision loss after stroke or brain injury. The first step in Vision Restoration Therapy is the diagnosis and evaluation of the patient's visual field deficit. Next, customized therapy is created to stimulate the border of the blind area, thereby encouraging neuroplasticity. The therapy routine is completed at home in two 30-minute sessions per day for approximately six months. The vision therapy program is analyzed and updated as the patient improves.
Research has shown that three factors must be present for neuroplasticity-based therapies to be effective: environmental stimuli, frequent and consistent stimulation for the proper amount of time, and motivation and attention on the part of patients. VRT was designed with these fundamentals in mind. In developing the therapy, NovaVision focused on ease of use and the effective, ongoing stimulation of the brain's self-repair mechanisms
