Show Answers:

  1. Aphasia (Dysphasia)
    an acquired neurological impairments of processiong for receptive and/or expressive language
  2. Fluent Aphasia
    • Lesion often in temporoparietal lobe of dominant hemisphere
    • word output is functional
    • speech production is functional
    • "EMPTY SPEECH" or jargon
    • paraphasis (substitution of incorrect words)
  3. Wernicke's Aphasia (receptive aphasia)
    • Lesion found at the posterior region of the superior temporal gyrus
    • Major fluent aphasia
    • comprehension (reading/auditory) impairment
    • paraphasias
    • severe impairment with repetition
    • good articulation
    • impaired writing
  4. Conduction Aphasia
    • lesion of the supramarginal gyru and arcuate fasciculus
    • major fluent aphasia
    • severe impairment with repetition
    • good comprehension
    • speech interrupted by word-finding difficulties
    • reading intact
    • writing impaired
  5. Anomic Aphasia
    • Lesion of angular gyrus
    • minor fluent aphasia
    • word finding difficulties with writing and speech
    • functional comprehension
    • speech can seem empty; words regarding content are dropped
  6. Non-fluent Aphasia
    • Lesion often in frontal region of the dominant hemisphere
    • poor word output
    • increase effort for producing speech
    • poor articulation
    • dysprosodic speech (bad pitch or timing)
    • content of speech is present, but syntactical words are impaired
  7. Broca's Aphasia (expressive ahpasia)
    • major non-fluent aphasia
    • most common
    • lesions of the 3rd convolution of frontal lobe
    • intact auditory and reading comprehension
    • impaired repetition and naming skills
    • frequent frustration regarding language skill errors
  8. Global Aphasia
    • major non-fluent aphasia
    • lesion of frontal, temporal, and parietal lobes
    • comphension (reading and auditory) is severely impaired
    • impaired naming and writing skills
    • impaired repetition skills
  9. verbal apraxia
    a non-dysarthric and non-aphasic impairment of prosody and articulation of speech
  10. Dysarthria (slurred speech)
    a motor disorder of speech that caused by an upper motor neuron lesion that affects the muscles that are used to articulate words and sounds
