![]() This is sometimes called “visual dependency.” When there is a conflict between the visual system and the other systems, the brain is more likely to believe the visual system and decide that you are moving when you are not. With visually induced dizziness, the brain relies too much on information from the visual system and not enough on the vestibular and proprioceptive systems. Normally, your brain takes all these signals and correctly assesses the situation: you can see movement, but your body is not moving. For example, if you are watching a movie, the visual system says there is motion, but the vestibular and proprioceptive systems say that your head is not moving and your body is sitting in a chair. Balance is achieved and maintained by a complex set of sensorimotor control systems.Īt any moment, your brain is evaluating all these different signals and deciding which ones are more important and reliable at that moment. the proprioceptive system, which sends signals about position, pressure, movement and vibration from the legs and feet and the rest of the bodyįIGURE 1.the vestibular system (the semicircular canals and otoliths in the inner ear), which senses when your head tilts, turns or changes speed.The brain’s balance system combines information from many sources, including: Others believe that it happens when a vestibular problem causes the brain to rely too much on visual signals for balance (visual dependency). Most researchers believe that it is caused by a mismatch or conflict between the different parts of the brain’s balance system, similar to motion sickness. There are several theories about why visually induced dizziness happens. Large areas of complex patterns or movement.It can also be referred to as visual vertigo, space and motion discomfort, supermarket syndrome or visual vestibular mismatch.Ĭhronic (long lasting) symptoms of dizziness or unsteadiness can be made worse by: Visually induced dizziness is an umbrella term for a group of symptoms that result from some vestibular disorders. If you can relate, you are not alone and there is nothing “wrong” with you. Do you dread going to the grocery store because it makes you feel bad? The maze of tall shelves, the bright lights, patterns on the floor, the overwhelming selection of items, bending down or turning your head to scan for the items you need can take a lot of energy to navigate.
