Is Alice in Wonderland syndrome a mental illness?

Alice in Wonderland syndrome (AIWS) is not a mental illness per se, but rather a neurological condition that affects perception. It is also known as Todd’s syndrome, and it is characterized by episodes of distorted perception, including changes in the size, shape, and distance of objects, as well as alterations in the perception of one’s own body. AIWS can occur in people with migraines, epilepsy, infections, or brain tumors, among other conditions. While AIWS can be unsettling and confusing, it is not typically considered a mental illness because it is not caused by psychological factors or a mental disorder.
