Illusions of Tilt and Inversion
摘要
An inversion illusion or illusion of tilt is when an individual feels as if the world has flipped completely or partially upside-down or on its side. This is very rare. It is more common in men, and tends to begin when a person is in their 50s. Illusions of tilt and inversion can occur in some otologic and some neurologic diseases. A workup can reasonably include a brain MRI.
