These learning questions are brought to you by the KnowNeuropsychology / APPCN collaboration.

*This quiz has 16 multiple-choice questions.

1 / 16

What part of the brain is most involved in processing somatosensory information?

frontal lobe

parietal lobe

temporal lobe

occipital lobe

2 / 16

The right parietal lobe:

coordinates overlearned motor routines and linguistic abilities

plays a key role in directing attention and coordinating visual and spatial skills

single-handedly processes all somatosensory information

is involved in abstract thinking and reasoning

3 / 16

The temporal lobe:

contains the primary auditory cortex

processes verbal memory and language comprehension

processes visual memory

all of the above

4 / 16

What type of attention requires you to maintain attention to a specific stimulus despite competing stimuli and/or distractors?

sustained attention

selective attention

divided attention

alternating attention

5 / 16

What are the different types of long-term memory (i.e., information recalled over a delay)?

learning, implicit, autobiographical, and semantic

semantic, phonemic, autobiographical and recognition

implicit, autobiographical, procedural, and learning

free recall, cued recall, and recognition

6 / 16

Normal age-related decline:

starts at approximately age 50 and is similar among age related peers

involves slower processing and decreased ability to multitask

involves increased distractibility and mild word finding difficulties

all of the above

7 / 16

True/False: The most important distinguishing factors between mild cognitive impairment and dementia are the preservation of independence in functional abilities (ADL’s and iADL’s) and lack of significant impairment in social or occupational functioning.

True

False

8 / 16

Mild Cognitive Impairment can be divided into the following categories:

amnestic vs. non-amnestic

single domain vs. multiple domain

memory vs. movement

both a and b

9 / 16

True/False: Currently, all forms of mild cognitive impairment are irreversible.

True

False

10 / 16

Dementia is:

The decline and progressive worsening of memory related processes that negatively impacts one’s ability to function in their daily lives due to brain disease.

The decline and progressive worsening of all cognitive functions and comportment from a prior customary level of functioning thus impacting one’s daily life, due to brain disease.

The decline and progressive worsening of one or more cognitive functions and/or comportment from a prior customary level of functioning due to irreversible brain disease.

The decline and progressive worsening of mental abilities due to brain disease.

11 / 16

True/False: Symptoms of dementia can begin a decade or two prior to diagnosis.

True

False

12 / 16

What is the estimated number of Americans living with Alzheimer’s disease currently?

9 million

6.2 million

5.3 million

1 billion

13 / 16

MCI impacts memory primarily.

True

False

14 / 16

What is the greatest risk factor for MCI?

ApoE genotype

Gender

Age

Low education level

15 / 16

Parkinson’s disease dementia and Dementia with Lewy Body frequently coexist with AD.

True

False

16 / 16

Bonus Question: Which biomarkers are currently being used (mostly in research settings) to diagnose dementia in vivo rather than via post-mortem examination?

β-amyloid plaques

neurofibrillary tau deposits

amyloid, Tau, neurodegeneration [AT(N)] classification system

all of the above
