The effects of a stroke can be wide ranging. Some symptoms are common such as affected communication and partial paralysis or restriction to part of the body.
Less well known is that in about 20% of cases of stroke, there can be visual or perceptual consequences. When a stroke occurs in the visual regions of the brain, there is an increased chance of visual disturbances including CBS. Unlike most cases of CBS due to eye disease, in many instances of stroke-induced CBS, the affected person retains central vision (visual acuity) even though they may well experience some form of visual field loss.
A fresh discussion is warranted on this topic. The stroke community needs to be aware that CBS is a possible consequence of stroke and that accurate information is available to the stroke-survivor as well as their loved ones.
