<s>[INST] What are the symptoms of a stroke? [/INST] Before any of the symptoms (listed below) occur, there may be a sudden onset of the "worst headache of your life." The following symptoms of stroke can occur together, or only one or two symptoms may occur:

Sudden numbness or weakness of face, arm, or leg on one side of the body.
Sudden confusion, trouble speaking or understanding.
Sudden difficulty seeing or loss of vision.
Sudden trouble walking, dizziness, or imbalance.
These symptoms may be mild or severe in nature and may be temporary or permanent. If they are temporary (i.e., typically lasting 5-15 minutes), the episodes are referred to as transient ischemic attacks (TIAs). TIAs are important warning signs of a possible impending stroke and require urgent evaluation. Source: EMORY HEALTH CARE.
