Review
5
The Wernicke-Lichtheim-Geschwind model (of the LH)
6
What the numbers mean

• 0. Cortical deafness
• 1. Pure word deafness (auditory-verbal agnosia)
• Auditory agnosia (output from A1 to natural sound
  recognition)
• Phonagnosia (output from A1 to voice recognition)
• 2. Posterior/receptive/Wernicke's aphasia

7
Language areas of brain
8
Wernickes aphasia

• aka posterior aphasia
• aka receptive aphasia

9
Logorrhea, press of speech

• The ease with which Wernickes patients produce
  speech, their circumlocution, and their deficient
  self-monitoring may contribute to their
  inclination to run on when they talk.
• Such an overabundance of speech is referred to as
  logorrhea or press of speech.
• Clinician Tell me what you do with a comb.

10
Logorrhea, press of speech

• Patient What do I do with a comb what I do
  with a comb. Well a comb is a utensil or some
  such thing that can be used for arranging and
  rearranging the hair on the head both by men and
  by women. One could also make music with it by
  putting a piece of paper behind and blowing
  through it. Sometimes it could be used in art
  in sculpture, for example, to make a series of
  lines in soft clay. Its usually made of plastic
  and usually black, although it comes in other
  colors. It is carried in the pocket or until its
  needed, when it is taken out and used, then put
  back in the pocket. Is that what you had in
  mind? (Brookshire 2003155)

Reading

• Reading can also be disrupted?
• Why?
• Because reading connects to speech for the
  pronunciation of letters and the storage of words

12
Aphasia checklist Wernickes

• comprehension of spoken material
• comprehension of written material
• segmental phonology
• word selection
• word semantics
• fluency (production of speech)
• production of writing
• use function words
• grammaticality
• repetition of what others say
• conversational proficiency, e.g. turn taking
• concern about impairment
• concern about errors
• short-term retention recall of verbal materials

• impaired, mild to severe

• impaired (no evidence)
• normal
• little to none
• little to none
• impaired (no evidence)

The effect of WA on cerebral function
14
Evaluation treatment

• There are many tests for evaluating language, but
  we do not have time to talk about them.
• We also will not talk much about treatment,
  because our access to patients is limited.

15
Recovery

• How is it that patients can recover from
  Wernickes aphasia?
• The corresponding area of the right hemisphere
  takes over the functions of Wernickes area

16
Next time

• Transcortical sensory aphasia
