The aphasias
- Conduction Aphasia
- verbal output: fluent some paraphrasis
- Associated signs: Righthemiparesis,
sensory loss, hemianopsia; apraxia.
- Region Affected: left superior
temporal and supramarginal gyrus
- Repetition: Intact
- Comprenhension: Impaired
- Verbal Output: fluent,
word-finding pauses
- Assosiated Signs: Variable
- Region Affected: left temporal, left
angular gyrus.
- Repetition: Intact
- Comprenhension: Relatively preserved
- Anomic Aphasia
- Broca's Aphasia
- Verbal Output: Nonfluent, efforful
- Associated Signs: Right hemiparesis,
right hemisensory loss: apraxia of left
limbs
- Region Affected: Left inferior frontal,subcortical white matter
- Repetition: Impaired
- Comprenhension: Relatively intact, difficulty with complex syntax
- Wernicke's Aphasia
- Verbal ouput: Fluent, paraphasic errors: logorrhea
- Associated Signs: Right hemianopsia
- Region Affected: Left posterior superior temporal; inferior parietal
- Repetition: Impaired
- Comprenhension: Impaired
- Cortical Syndromes
- Gerstmann's Syndrome
- Acalculia (can't do simple arithmetic),
Finger agnosia (do not recognize
fingers), issues with left/right
discrimination, agraphia Key
features - Lesion in angular gyrus of
dominant parietal lobe
- Anton Syndrome
- Is Cortical blindness = blindness caused
by issues at occipital lobe (eyes are
normal) ○ Confabulates respones and
excuses; hallucinations - Patient will deny
being blind - Lesion caused by bilateral
acute ischemic strokes in occipital cortex
- Balint's Syndrome
- ○ Simultanagnosia = inability to
perceive visual field as a whole ○
Oculomotor apraxia = cannot FIX
eyes to a spot ○ Optic
ataxia/dysmetria = cannot guide
hand towards object using visual
cues - Features - Lesion to bilateral
superior temporal-occipital lobes
(commonly with watershed
infarcts)
