Major Clinical Syndromes of MCA, ACA, PCA Territories

Right face and arm weakness of UMN
Nonfluent or Broca's aphasia
Right face and arm cortical type sensory loss

Fluent, Wernicke's aphasia
Right visual field deficit
Right arm and face cortical sensory loss
Motor findings are usually absent
Patient may be initially confused or crazy but otherwise intact
Mild right side weakness may be present especially at onset of symptoms

Right pure motor hemiparesis of UMN type
Larger infarct may produce cortical deficits such as aphasia

right hemiplegia
right hemianesthia
right homonymous hemianopia
global aphasia
Left gaze preference

Left face and arm weakness of UMN
left hemineglect
may be some sort of face and arm cortical type sensory loss

Profound left hemineglect
left visual field deficit
somatosensory deficit however may be difficult to test because of neglect
Motor neglect with decreased voluntary/spontaneous initiation of movements on left side
If patient with left motor neglect have normal strength on L side as evidence of spontaneous movments or purposeful withdrawl from pain
Mild left side weakness
Right gaze preference at onset

Left pure motor hemiparesis
Left hemiplegia
Left hemianesthesia
left homonymous hemianopia
LEFT neglect
Right gaze preference

Right leg weakness of UMN type
right cortical type sensory loss
Grasp reflex and frontal lobe behavioral abnormalities
Transcortical aphasia
Right hemiplegia

Left leg weakness of UMN
Left leg cortical type sensory loss
Grasp reflex and frontal lobe behavioral abnormalities
Left hemineglect
Left hemiplegia

Right homonymous hemianopia
Extension to the splenium of corpus callosum can cause alexia without agraphia
Larger infarcts include thalamus and internal capsule may result in aphasia, right hemisensory loss and right hemiplegia

Left homonymous hemianopia
Larger infarcts including thalamus and internal capsule cause left hemisensory loss and left hemiparesis

Conduction aphasia

orbital gyrus
cingulate gyrus
