Aphasia Category: classification

MOTOR APHASIA - nonfluent afasia
less output, bad articulation, dysprosody (melody), agrammatism, auditory understanding relatively intact, ideomotor apraxia contralateral limbs
lokalisation
repetition disturbed: Broca’s area (g.frontalis inf.)
repetition intact: cortex around Broca’s area, suppl. motorcortex (transcortical motor aphasia)

SENSORY APHASIA – fluent afasia
increased output,­ normal articulation, “empty speech”, disturbed auditory understanding, paraphasias
lokalisation
repetition disturbed: Wernicke’s area (g.supramarginalis, g.angularis)
repetition intact, bad articulatie: g. angularis, g. temporalis sup (transcortical sensory aphasia)

GLOBAL APHASIA
mixed sensomotor
lokalisation: extensive lesion dominant hemisphere

CONDUCTION APHASIA
output fluent, paraphasias, intact understanding, repetition severely disturbed
lokalisation: g.supramarginalis, f.arcuatus

SUBCORTICAL APHASIA
first: mutism, hypophonia, dysarthria, less output , paraphasias, intermittend repetition disturbance
later: good recovery (despite permanent CT abnormalities)
lokalisation: n.caudatus, putamen, thalamus
