Aphasia Types Flashcards
Nonfluent Aphasia
Broca’s
Transcortical motor
global
mixed transcortical
Fluent Aphasia
Wernickes transcortical sensory Conduction Anomic Subcortical
Locus of Broca’s
Broca’s area in posterior inferior frontal gyrus-
–MCA
Locus of transcotical motor
Anterior superior frontal lobe (below or above Broca’s)
–ACA and MCA
Locus of Global
extensive damage to all language areas (perisylvian region),
-MCA
Locus of Mixed transcortical aphasia
watershed areas/arterial border zone
Locus of Wernicke’s
Wernicke’s area in the posterior portion of the superior temporal gyrus
-posterior MCA
Locus of Transcortical sensory
Temporoparietal region (posterior portion of the middle temporal gyrus)
-posterior MCA
Locus of Conduction
Supramarginal gyrus and arcuate fasciculus (between Broca’s and Wernicke’s)
Locus of Anomic
Different regions including angular gyrus and temporal gyrus
Locus of subcortical
areas surrounding basal ganglia and thalamus
Subcortical characteristics
Word-finding problems
Good comprehension
Good comprehension
subcortical
language functions other than naming are generally normal
Anomia
good to normal auditory comprehension but
Severe to mild naming prob.
Conduction
good repetition
Intact grammar and syntax
Empty speech
Severe naming difficulties
Transcortical sensory
paralysis is uncommon
Severe word finding
Empty speech
Wernicke’s
severe echolalia
reading and writing difficulties
associated with bilateral UMN and visual field deficits
Mixed transcortical aphasia
verbal and nonverbal apraxia
strong neurological symptoms
most severe form
Global
Laborious Halting Telegraphic akinesia bradykinesia apraxia
Transcortical motor
Broca’s
Effortful
Slow
Halting
Uneven speech
