5. Vision changes
Another side effect of a mini stroke is changes in vision. Vision may become double or blurred, for example, and one or both eyes may be affected. While a mini stroke does not cause permanent damage to the brain cells, it can certainly disrupt them. If the mini stroke disrupts the part of the brain that affects the visual pathways to the eye, the visual field can be altered.
As mentioned, when this happens, vision can become blurry, or the patient may find that they experiencing double vision (it literally looks as if they are seeing two of something). A patient can also have a hard time processing the visual information that they are receiving, which can make it hard to make sense of what they are seeing. Vision problems can further compound other symptoms of a mini stroke, such as dizziness and issues with maintaining balance.
