Spur's symptom

The visor symptom/spur symptom/v-sign is a neurological syndrome during stroke, characterized by “oblique” downward oscalopathic nystagmus and (sometimes) ventriculectasia (dilation of the ventricles of the brain).

Described by Harosz Deutsch in 1965. 45% of patients suffering from type B stroke have a visor symptom.

The visor symptom is an important sign that helps recognize stroke, especially in patients with a clinical picture of intracerebral hemorrhage, and its presence may indicate that the person is in critical condition. This symptom has clinical value in the acute stage, since in the chronic stage it is not informative.
