History and Symptoms

Detailed history may suggest the underlying cause for ischemic stroke. The symptoms of a stroke are related to the anatomical location of the damage; nature and severity of the symptoms can therefore vary widely

Vessel involved	Site of infarction	History and symptoms
Anterior cerebral artery Rare Collateral circulation by anterior communicating artery	Frontal lobe Frontal cortex, Primary motor cortex	Motor weakness opposite the side of lesion Sensory loss on the same side of lesion Urinary incontinence Transcortical aphasia Abulia Disorganized thinking
	Parietal lobe Primary sensory cortex	Hemineglect (left ACA) Behavioral abnormalities
Middle cerebral artery Most common site of infarction	Right superficial division (RSD) Motor cortex (left head,neck and arm) Sensory cortex (left head, trunk and arm)	Left arm and face weakness Hemineglect
	Left superficial division (LSD) Broca's area (expressive speech area) Wernick's area (receptive speech area) Motor cortex (right head, neck and arm) Sensory cortex (right head, neck and arm)	Right arm and facial weakness Hemineglect Non fluent aphasia (Broca's aphasia) Fluent aphasia (wernick's aphasia)
	Lenticulostriate branches Striatum (caudate and putamen) Globus pallidus Internal capsule (anterior limb and genu)	Pure upper motor weakness
Posterior cerebral artery	Superficial branch Occipital cortex Splenium of corpus callosum	Homonymous hemianopsia Alexia without agraphia.
	Deep branch Thalamus Internal capsule (posterior limb)	Hemisensory loss Hemiparesis
Vertebrobasilar artery	Midbrain	Weber syndrome
	Medulla	Lateral medullary syndrome Medial medullary syndrome
	Pons	Locked-in syndrome
	Cerebellum	Difficulty maintaining balance Vertigo Nausea Vomiting Tremors
	Thalamus
	Occipital cortex
