MoCA Language 3 — Questions and Answers
Question 1: What does a score below 11 words on the MoCA letter fluency task indicate about cognitive function?
- Possible impairment in executive and language function (Correct answer)
- Isolated memory deficit only
- Normal aging variation
- Frontal lobe damage exclusively
Correct answer: Possible impairment in executive and language function
Letter fluency below 11 words suggests reduced executive control over word retrieval, which can reflect cognitive impairment across multiple domains.
Question 2: Which condition most commonly causes difficulty on the MoCA naming subtest due to progressive loss of object knowledge?
- Semantic dementia (Correct answer)
- Alzheimer's disease (early stage)
- Vascular dementia
- Depression
Correct answer: Semantic dementia
Semantic dementia involves progressive degradation of semantic memory, leading to profound naming failures even for common objects and animals.
Question 3: The MoCA repetition task is most sensitive to deficits in which cognitive-linguistic ability?
- Phonological working memory and syntactic processing (Correct answer)
- Semantic memory
- Visual-spatial integration
- Procedural memory
Correct answer: Phonological working memory and syntactic processing
Repeating complex sentences requires holding phonological sequences in working memory while processing syntax, making this task sensitive to phonological and syntactic deficits.
Question 4: A patient scores 0/2 on naming but 1/1 on fluency. Which interpretation is most accurate?
- Confrontational naming is impaired but word retrieval with phonemic cue is preserved (Correct answer)
- All language functions are equally impaired
- Fluency score invalidates the naming failure
- The patient has alexia
Correct answer: Confrontational naming is impaired but word retrieval with phonemic cue is preserved
Dissociation between confrontational naming and phonemic fluency can occur; fluency provides a retrieval cue (letter) while naming requires unaided access to the word.
Question 5: Why does the MoCA use uncommon animals (lion, camel, rhinoceros) rather than a dog or cat for naming?
- To reduce ceiling effects and better detect mild naming deficits (Correct answer)
- Because pictures of pets are harder to draw
- To test cultural knowledge
- To assess visual acuity
Correct answer: To reduce ceiling effects and better detect mild naming deficits
Common animals are named correctly even by individuals with significant cognitive decline, so less familiar animals create a more discriminating test.
Question 6: How many total points can a patient earn on the MoCA Language domain across all language subtests?
- 6 (Correct answer)
- 5
- 4
- 3
Correct answer: 6
Language contributes 6 points: 3 for naming, 2 for repetition, and 1 for letter fluency.
Question 7: Which MoCA language subtest asks the patient to produce language spontaneously rather than repeat or recognize?
- Letter fluency (Correct answer)
- Sentence repetition
- Animal naming
- Orientation
Correct answer: Letter fluency
Letter fluency requires the patient to self-generate words, making it the only MoCA language task that demands spontaneous verbal production.
