A stroke, also known as a cerebrovascular accident (CVA), shows specific signs and symptoms that are crucial for quick identification and treatment. Common warning signs include sudden weakness, known as hemiparesis, where one side of the body may become weak or paralyzed. Numbness, especially on one side of the body, can also be a significant indicator of a stroke as it may affect an arm, leg, or the face. Severe headaches can occur during a stroke, particularly if it involves bleeding in the brain, indicating a possible hemorrhagic stroke.

However, a dry mouth is not typically associated with a stroke. While certain conditions may cause dry mouth, it does not correlate with the neurological and physical symptoms that are emphasized in stroke assessments. Recognizing the hallmarks of a stroke ensures timely medical intervention, which can be critical for patient outcomes.
