Vision problems Blurred or double vision, or temporary loss of vision in one or both eyes, may indicate a reduced supply of oxygen to the vision centers in the brain.
Numbness or tingling Tingling or numbness, especially on one side of the body, is often an early warning sign. This may indicate poor blood flow to certain areas of the brain responsible for sensation.
Difficulty speaking Difficulty speaking, slurred speech, or difficulty understanding speech, even temporarily, may indicate a transient ischemic attack (TIA), also called a “mini-stroke.”
Dizziness or balance problems Recurring dizziness, unsteadiness, or difficulty walking can occur when the balance centers in the brain are affected by poor blood flow.
Unusual pain Some people experience unexplained pain, especially in the face or extremities. This can result from nerve irritation due to limited blood flow.
