A patient who is diagnosed with a CVA or cerebrovascular accident is likely seen more prone towards hemiparesis and in course of time if fatal can lead to hemiplegia as well. Here the patient is suffering from left-sided hemiparesis. This means that the right hemisphere of the brain is the one that has got affected due to CVA. Here it is not necessary that all facial nerves and muscles on the left side of the body may undergo weakness. It can also happen in a way that only facial nerve is affected as in the case of Bell's muscles or muscles are affected as in this case here. If left-sided hemiparesis does not affect vision or sensation, it shows that the movement of all muscle is restricted or perhaps only muscles are affected without affecting nerves. Another most important point to be noted here is that hemiparesis could have affected the frontal and parietal lobe, but not the occipital and temporal lobe. This is because, by making the statement that the patient has good vision and sensation, the point highlighted is that the occipital lobe responsible for the vision and temporal lobe responsible for the sensation of touch is intact.
