speech and aphasia Flashcards

1
Q

components of a mental status examination

A
  1. Arousal and attention - level of consciousness, digit span, serial sevens. 2. Memory - orientation, three words at five minutes, remote events 3. Language - fluency, comprehension, repetition, naming, reading, writing 4. Visuospatial function - clock drawing, tests for hemineglect 5. Mood and affect - inquiries about feelings, observations of affect 6. Complex cognition - executive function, similarities, proverbs, judgment, insight

Q

brain structures involved in speech

A

motor cortices, corticobulbar tracts, basal ganglia, cerebellum, lower motor neurons innervating the pharyx and larnyx, and pharyngeal and laryngeal muscles. Cerebral cortex is required for language.

Q

describe cerebral dominance

A

language is represented in left hemisphere in most people. While 90% of population is right handed and 10% left handed, 99% of right handed people are left dominant for language but 67% of left handers are also left dominant for language.

16
Q

testing for aphasia

A

requires the assessment of spontaneous speech, auditory comprehension, repetition, and naming. In literate individuals, reading and writing should also be examined, as impaired reading (alexia) and writing (agraphia) typically accompany aphasia

17
Q

what is nonfluent spontaneous speech

A

labored, effortful speech and <6 word phrases

18
Q

what area of brain is language associated with

A

perisylvian area, including brocas and wernickes area

19
Q

what is a paraphasia

A

unintended sullables or words. 1. literal (pipe becomes hike), 2. verbal/semantic (wife becomes mother), 3. neologism (new and meaningless words)

20
Q

What is impaired in all types of aphasias

A

naming common items

21
Q

For Brocas aphasia, describe spontaneous speech, auditory comprehension, repetition, naming and localization

A

Nonfluent spontaneous speech, good auditory comprehension, poor repetition, poor naming, localized to Broca’s area in left hemisphere

22
Q

For Wernickes aphasia, describe spontaneous speech, auditory comprehension, repetition, naming and localization

A

Fluent spontaneous speech, poor auditory comprehension, poor repetition, poor naming, localized to Wernicke’s area in left hemisphere

23
Q

For conduction aphasia, describe spontaneous speech, auditory comprehension, repetition, naming and localization

A

Fluent spontaneous speech, good auditory comprehension, poor repetition, poor naming, localized to Arcuate fasciculus area in left hemisphere

24
Q

For global aphasia, describe spontaneous speech, auditory comprehension, repetition, naming and localization

A

Nonfluent spontaneous speech,poor auditory comprehension, poor repetition, poor naming, localized to Perisylvian region in left hemisphere

25
Q

For transcortical motor aphasia, describe spontaneous speech, auditory comprehension, repetition, naming and localization

A

Nonfluent spontaneous speech, good auditory comprehension, good repetition, poor naming, localized to Anterior borderzone region in left hemisphere

26
Q

For transcortical sensory aphasia, describe spontaneous speech, auditory comprehension, repetition, naming and localization

A

Fluent spontaneous speech, poor auditory comprehension, good repetition, poor naming, localized to Posterior borderzone region in left hemisphere

27
Q

For anomic aphasia, describe spontaneous speech, auditory comprehension, repetition, naming and localization

A

Fluent spontaneous speech, good auditory comprehension, good repetition, poor naming, localized to angular gyrus region in left hemisphere

28
Q

For mixed transcortical aphasia, describe spontaneous speech, auditory comprehension, repetition, naming and localization

A

Nonfluent spontaneous speech, poor auditory comprehension, good repetition, poor naming, localized to angular gyrus region in left hemisphere

29
Q

aphasia treatment

A
  1. treat causative lesion. Most functional improvement in language and cognition occurs in first year. Prognosis depends on size of lesion and age of patient (ie. Young patients with small lesions recover best). 2. speech/language therapy
