subcortical aphasia
Transocrtical Motor Aphasia
caused by lesions in the region between Broa's and Wernicke's area in the supramarginal gyrus and arcuate fasciculous
caused by lesion in the anterior superior frontal lobe
Wernicke's aphasia
caused by lesion in the watershed area; middle cerebral aretery and anterior posterior arteries
caused by lesions in temporpoparietal region of the brain in the posterior protion of the midddle temporal gyrus
cused by lesions in the angulary gyrus, temporal gyrsu and temporoparietal lobes
Mixed Transcortical Aphasia
Global Aphasia
caused by damage to Broca's area; posterior inferiror frontal gyrus
caused by lesions in the posterior portion of the superior temporal gyrus
Conduction aphasia
Transocrtical Sensory apahasia
Broca's Aphasia
caused by extensive lesions affecting all language areas
lesionsin the basal ganglia and thalamus are linked to subcortival aphasia in the left hemisphere
