1

Cognitive domains (+ tests used) assessed by mental status exam

  • Arousal and attention = level of consciousness, digit span, serial sevens
  • Memory = orientation, three words at five minutes, remote events
  • Language = fluency, conrehension, repetition, naming, reading, writing
  • Visuospatial function = clock drawing, tests for hemineglect
  • Mood & affect = inquires of feelings, observations of affect
  • Complex cognition = executive fxn, similarities, proverbs, judgement, insight

2

Amnesia vs. Aphasia

  • Amnesia = impaired recent memory, w/deficient new learning
  • Aphasia = aquired disorder of language

3

Aphasia vs. Dysarthria vs. Dysphonia

  • Aphasia = acquired disorder of language
  • Dysarthria = disorder of speech due to motor system problems
  • Dysphonia = disorder of voice due to laryngeal disease

4

Handedness vs. Cerebral language dominance

  • most people: language @ left hemisphere
  • 90% of population = R-handed; 10% = L-handed
  • 99% of R-handed people = LEFT language dominant
  • 67% of L-handed people = LEFT language dominant
    • only ~8% of people are Right language dominant (and if they are, they are most likely left-handed)

6

Important components of aphasia assessment

  • spontaneous speech
  • auditory comprehension
  • repetition
  • naming

7

Presentation of aphasia

  • due to complexity of language ==> various types of aphasia
  • sydrome of aphasia = specific type/set of impairments ==> specific neuroanatomic lesion

8

Broca's aphasia: speech, auditory, repetition, naming, localization

  • speech = nonfluent
  • auditory = good
  • repetition = poor
  • naming = poor
  • localization = Broca's area (L hemisphere)

9

Wernicke's aphasia: speech, auditory, repetition, naming, localization

  • speech = fluent
  • auditory = poor
  • repeitition = poor
  • naming = poor
  • localization = Wernicke's area (L hemisphere)

10

Conduction aphasia: speech, auditory, repetition, naming, localization

  • speech = fluent
  • auditory = good
  • repetition = poor
  • naming = poor
  • localization = arcuate fasciculus (L hemisphere)

11

Global aphasia: speech, auditory, repetition, naming, localization

  • speech = nonfluent
  • auditory = poor
  • repetition = poor
  • naming = poor
  • localization = perisylvian region (L hemisphere)
