Psychotherapy: 124b - Neuropsychological Assessment

Question 1

Describe the process of making a memoryWhich structures are involved?Where is it stored?

Accepted Answer

Incoming stimulus is rehearsed in working memory (prefrontal cortex) for as long as necessary…to consolidate by mesial temporal cortex (hippocampus)Stored as long term memory in different parts of the cortexRetrieved w/help of hippocampus and prefrontal cortex

Question 2

The normal range is ___ standard deviations around the meanWhat does this mean for percentiles?

Accepted Answer

The normal range is 1.3 standard deviations around the meanThis translates to 9th-90th percentiles(Mean = 100, standard deviation = 15)

Question 3

List the two distinct visual pathways after reaching the occipital lobeWhich areas of the brain are they associated with?

Accepted Answer

“Where” = parietal = dorsal streamLegion: will not be able to put an envelope into a mail slot“What” = temporal = ventral streamLegion: will not be able to tell you that a horizontal line matches the mail slotEverybody pls vote

Question 4

How is this patinet’s encoding?Retreival?Retention?What is the most likely diagnosis?

Accepted Answer

Impaired encodingDoes not learn additional words with more repetitionImpaired retreivalBut makes sense, bc not encodedIntact retentionRetains what is learned, but cannot access/retreive without the examiner asking “have you seen this word before”The diagnosis from the lection is vascular dementiaPoor encoding, normal retention

Question 5

Which brain structures are involved in anterograde memory?

Accepted Answer

Anterograde memory = learning and consolidating new information

Mesial temporal cortex (hippocampus)
- Consolidates and distributes memories for long-term storage
Prefrontal cortex
- Memory eencoding and retreival

Question 6

How is this patinet’s encoding?Retreival?Retention?What is the most likely diagnosis?

Accepted Answer

Preserved encodingLearns additional words with increased repetitionImpaired retreivalFewer workds immediately and after delayImpaired retentionWe would expect ~5/12 correct when asking yes/no questionsThis is likely Alzheimer’sNormal encoding, poor retention

Question 7

What is the mean and standard deviation of a Standard Score?

Accepted Answer

Mean = 100Standard deviation = 15

Question 8

When is a neuropsychology consultation indicated?

Accepted Answer

Suspected dementiaAssess cognitive sequalaeTBIHIV/AidsAutoimmune conditionsPsychiatric conditionsSuspected developmental disorderPre/post treatment baselineThe neurocognitive test is long; requires patients to have intact decision making capacity and to be cooperativeNot necessary for reversible causes of altered mental status
