Uhthoff's phenomenon (also known as Uhthoff's syndrome, [ 1] Uhthoff's sign, [ 1] and Uhthoff's symptom) is the worsening of neurologic symptoms in multiple sclerosis (MS) and other demyelinating diseases when the body is overheated. This may occur due to hot weather, exercise, fever, saunas, hot tubs, hot baths, and hot food and drink.

As in other kinds of stereoscopy, glasses are used to create the illusion of a three-dimensional image. By placing a neutral filter (e.g., the darkened lens from a pair of sunglasses) over one eye, an image, as it ...
Secondly, Uhthoff's phenomenon has quite a detailed medical description which is somewhat separate from demyelinating diseases more generally - as the article now stands at over 3,600 characters of readable prose, there is perhaps too much detail too well sectioned for a merge with Multiple sclerosis (which also has over 46,500 characters of ...

Video of a spinning, patterned paper disc. At a certain speed the sets of spokes appear to slow and rotate in opposite directions. The wagon-wheel effect (alternatively called stagecoach-wheel effect) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation. The wheel can appear to rotate more slowly ...
