How MS affects the body's "input" functions
- Vision. Visual complications, such as double vision, white spots, or blurring might give confusing information to the brain as it tries to figure out where the body is relative to the ground or a chair.
- Inner ear. The inner ear is responsible for communicating with your brain about how your head is angled or which direction it is positioned. When an ailment such as MS affects the messages that your inner ear is trying to send to your brain, the information may be incomplete, disrupted, or delayed, which can all cause you to feel imbalanced.
- Sensory changes. MS often causes changes in sensations, including tingling, numbness, or needling. These changes in sensation may cause the brain to receive inaccurate or delayed information about what it needs to do to help you feel properly balanced.
