Alice in Wonderland Syndrome (AIWS), also known as Todd's syndrome or dysmetropsia, is a rare neurological condition characterized by transient episodes of perceptual distortions affecting visual, somatosensory, and temporal perceptions. This disorder disrupts the brain's processing of sensory input, leading to alterations in how individuals perceive their body image, the size and distance of objects, and the passage of time. First described in 1955 by psychiatrist John Todd, AIWS draws its name from Lewis Carroll's classic novel, where the protagonist experiences similar bizarre changes in perception. While more common in children, it can persist or emerge in adults, often linked to underlying conditions such as migraines or epilepsy.
The image presented demonstrates a classic clinical sign known as pitting edema, a condition characterized by observable swelling in body tissues due to fluid accumulation. This visual guide highlights the standard diagnostic physical examination technique used by healthcare professionals to distinguish this specific type of fluid retention from other forms of swelling. By applying direct pressure to the affected limb, a clinician can assess the severity and nature of the edema based on the tissue's response.
Adams-Oliver Syndrome (AOS) is a rare congenital disorder characterized by the combination of aplasia cutis congenita (ACC) and terminal transverse limb defects.
