Vision Functions

A stroke may cause vision deficits

The most common symptoms are dark areas (a black spot in the middle of the patient’s eyesight), blurred vision, being unable to move the eyes, agnosia (inability to recognize objects), and even hallucinations.

Why do you have trouble with your vision?

Neurological functions are those mediated by your brain and nerves; the occipital cortex, situated at the rear of the brain, processes the information and allows you to see distance, shape, movement, and color.

After a stroke, brain impairment results in disruption of information processing and transmission through the nervous system. This can translate into vision impairment, such as double vision, fluctuating vision, visual field defects, visual acuity problems, hemianopsia, eye movement problems, and strabismus.

Vision loss results from damage to the occipital lobe. Hemianopia (the loss of visual field on one side) is a result of stroke and is detected after 36% of right-brain strokes and 25% of left-brain strokes.

How to recover your vision after a stroke

Although research estimates that 80%–85% of our perception, learning, cognition, and activities are mediated through vision, vision impairment is often overlooked and undertreated. Therapy is addressed mainly to eye-motor deficits and specific sight disabilities (focusing, analyzing an entire picture). Exercises will have patients practice eye movement, e.g., cross their eyes, look forward, track moving pictures or text, observe pictures and try to note or remember details, and recognize objects faster.

One of the key neurological processes supporting post-stroke rehabilitation within the brain is its capacity to reorganize healthy neuron networks to form new information circuits. This process is called neuroplasticity.

NeuroAiD™ has been shown to boost the production of new neurons in the brain (neurogenesis) and to favor the connections between neurons (formation of synapses). These processes create a fertile brain environment for vision recovery.

What can you expect from NeuroAiD™ stroke treatment?

A clinical trial on 40 patients diagnosed with homonymous hemianopsia (same field loss on both eye), reported that patients receiving Neuroaid recovered on average 12% more visual field than patients receiving a placebo. Separately a case study* published in the European Neurology journal reports that the five patients who had vision disabilities reported improvements, with resolution of dipoplia and anopia.
