5. Changes to vision
A stroke can affect a person’s vision almost immediately. The patient’s vision can become blurred, double vision may develop, or there may be a loss of peripheral vision. These changes occur suddenly and without warning. It can be difficult for someone else to notice vision changes, so unless the person mentions it, you may not be able to notice that it is a sign of a stroke. However, if you suspect that a loved one has been affected by a stroke, asking that person if he or she is experiencing vision problems can confirm that a stroke has, indeed, occurred.
