One complication that may occur in someone who has developed multiple myeloma is hyperviscosity, due to an increase in protein in the blood. This occurs when the blood thickens, potentially causing clots. It slows down the flow of blood, which decreases the amount of oxygen your brain is receiving. That can lead to mental symptoms like confusion, as well as the signs of a stroke. These include weakness on one side of the body, dizziness, and slurred speech. Any time you experience stroke-like symptoms, you should immediately seek medical care. A doctor can determine whether multiple myeloma or something else is causing your symptoms.
