Alice-in-Wonderland syndrome (AIWS, named after the novel written by Lewis Carroll), also known as Todd's syndrome, is a disorienting neurological condition that affects humanperception. Sufferers may experience micropsia, macropsia, or size distortion of other sensory modalities. A temporary condition, it is often associated with migraines, brain tumors, and the use of psychoactive drugs. It can also present as the initial sign of the Epstein-Barr Virus (see mononucleosis).Anecdotal reports suggest that the symptoms of AIWS are fairly common in childhood, with many people growing out of them in their teens. It appears that AIWS is also a common experience at sleep onset. Alice in Wonderland Syndrome can be caused by abnormal amounts of electrical activity causing abnormal blood flow in the parts of the brain that process visual perception and texture.
Alice in Wonderland Syndrome (AIWS or AWS) describes a set of symptoms, the most famous of which are:
- Alteration of body image: the sizes of parts of the body are perceived incorrectly.
- Alteration of visual perception: the sizes of external objects are perceived incorrectly.
Most reports are about children experiencing AIWS symptoms, though many people experience it in later life. Many people say they had AIWS symptoms as a child, but 'grew out' of them around their teens.
