Neurological examinations performed in the case of suspected circulatory disturbance
1. Big picture
In suspected cerebral circulatory disturbance — acute ischemic stroke, transient ischemic attack (TIA), intracerebral hemorrhage, subarachnoid hemorrhage, vertebrobasilar insufficiency — the neurological examination has two urgent aims:
-
Recognize that the symptoms are vascular. Stroke usually causes sudden focal neurological deficit.
-
Localize the lesion and estimate severity. The examiner must decide whether the syndrome suggests:
-
anterior circulation / carotid territory,
-
posterior circulation / vertebrobasilar territory,
-
cortical, subcortical, brainstem, cerebellar, or spinal localization,
-
large-vessel occlusio
-
