Stroke chameleon

Stroke is a clinical diagnosis and the acute onset of focal neurological symptoms is the major indicator of stroke. Whereas typical stroke symptoms such as hemiparesis, amaurosis or dysarthria are easy to recognize, other stroke syndromes such as vertebrobasilar strokes or predominant neuropsychological manifestations are subject to misdiagnosis especially for non-neurologists. Misdiagnosis may be due to a non-vascular medical condition that simulates a stroke syndrome - a condition coined stroke mimicry . Or, a stroke may resemble another non-vascular clinical entity - a circumstance termed as stroke chameleon (Huff 2002).
