Which of the following is NOT a sign of stroke?

Facial swelling is not typically recognized as a sign of a stroke. Instead, strokes usually present with a set of specific neurological symptoms resulting from the interruption of blood flow to the brain. Common indicators include localized weakness, which often manifests as sudden difficulty in moving an arm or leg on one side of the body; slurred speech, which is characterized by unclear or altered speech patterns; and dizziness, which can suggest issues with balance or coordination associated with cerebrovascular events.

Localized weakness, slurred speech, and dizziness are all symptoms that align closely with the clinical presentations one would expect in an individual experiencing a stroke. Facial swelling does not have a direct correlation with stroke and is more likely connected to other medical issues, such as allergic reactions or infections. Thus, it stands out as the option that does not fit within the typical signs associated with a stroke.
