21
Q

What is a paraphasia error?

A

Substitution of words or parts of words

22
Q

What is a Literal or Phonemic paraphasia error?

A

Similar sounds

ex: “sound” for “found”

23
Q

What is a Verbal or Semantic paraphasia error?

A

Word substituted for another of the same

ex: “fork” for “spoon”

24
Q

What is Agrammatism?

A

Aphasia in which there is absence of grammatical structure in a sentence

25
Q

What is Anomia (anomic or nominal aphasia)?

A

Difficulty recalling words

26
Q

What is Echolalia?

A

Repetition (“echoing”) of words or vocalizations made by another person.

27
Q

What is Circumlocution?

A

Round about way of describing a word that cannot be recalled.
Often seen in
conjunction with anomia

28
Q

What is Neologism?

A

A “new word” that is well articulated but has meaning only to the speaker

29
Q

What is Jargon?

A

Well articulated but mostly incomprehensible, unintelligible speech. Associated with Wernicke’s aphasia.

30
Q

What is Stereotype?

A

Repetition of nonsensical syllables (e.g., “no, no, no”) during attempts at
communication

31
Q

What is the most widely accepted approach to aphasia?

A

Loss versus interference

32
Q

Describe loss versus interference approach to aphasia.

A

Brain interferes with linguistic operation

33
Q

What is Melodic Intonation Therapy (MIT)?*

A

Recruits right hemisphere for communication by incorporating melodies or rhythms with simple statements

34
Q

What types of aphasia is Melodic Intonation Therapy (MIT) useful in?

A

Nonfluent (Broca’s) aphasia

35
Q

What is the timeline for post-stroke recovery?*

A

Greatest improvement first 2-3 mo after onset

Drop in recovery aft 6 mo
