Alice In Wonderland Syndrome (AIWS)
Alice in Wonderland syndrome (AIWS, named after the novel written by Lewis Carroll), also known as Todd's syndrome or lilliputianhallucinations, is a disorienting neurological condition that affects human perception. Sufferers experience dysmetropsia (micropsia, macropsia, pelopsia, teleopsia) 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.
Signs and Symptoms of Alice in Wonderland Syndrome
• The foremost symptom of the Alice in Wonderland Syndrome is an altered body image. The person observes sizes of parts of the body wrongly. More often than not, the head and hands seem disproportionate; and in general, the person perceives growth of various parts rather than a reduction in their size.
• Another most significant symptom of the Alice in Wonderland Syndrome is that the patient perceives the sizes of various other objects inaccurately.
• The trademark symptom of Alice in Wonderland Syndrome is migraine.
• The individual loses a sense of time. For him, time seems passes either at a snail's pace, or passes too swiftly.
• Some people experience strong hallucinations; they may visualize things that aren’t there and may also get the wrong impression about certain situations and events.
• Also, like the visual perception gets warped, so does the auditory and tactile perception.
