Q

Monitoring Treatment Cognitive Side-effects

A

Medical treatment of the brain will result in changes to cognition
- e.g. electroconvulsive therapy
(ECT) for severe depression -> transient disorientation and memory problems

Q

Assessment during Awake Brain surgery

A

neuropsychologist can check the patients cognitive and motor skill impairments caused by the surgery as soon as possible

Q

Differential Diagnosis

A

symptoms, observed behavior, and cognitive ability are used to decide between different possible diagnoses
- e.g. distinguish between different types of dementia, such as Alzheimer’s or frontotemporal dementia

16
Q

Broca’s area

A

Left frontal lobe
- aphasia

17
Q

Voxel-based Lesion-Symptom Mapping (VLSM)

A
  • collect data on many patients with
    varying brain lesions
  • damaged and not damaged voxels in each brain can be identified
18
Q

Homotopic Organization

A

Brain symmetric organization
- Neurons connect the same areas on the left and right hemispheres of the cerebrum, via the corpus collosum

19
Q

3 Corpus Callosum Parts

A

Start from anterior to posterior
1. Genu (knee)
2. Main body
3. Splenium

20
Q

How does cognitive assessment has advantages over modern imaging methods?

A
  1. Impairments following LESIONS can be directly understand as subtractions from cognitive models
  2. Cognitive assessment gives more information about TYPE of processes involved
  3. Cognitive studies can reveal SURPPRISING results, that would not have been hypothesized
    - e.g. attentional neglect on the left side of objects
  4. Single changes in BEHAVIOR, e.g., strategy application can be noted in cognitive assessment
21
Q

Bedside testing

A
  1. Only limited TRAINING needed to administer
  2. EASILY interpretable results
  3. SIMPLE materials
  4. SHORT-administration time
  5. Can be completed in BUSY environments
22
Q

A clinical ‘bedside version’ of “Go/No-go” task

A

A measure of motor impulse control
- neurologist taps under the desk, once or twice

23
Q

The most famous and widely used bedside tests

A
  1. Mini-mental State Examination (MMSE)
  2. Montreal Cognitive Assessment (MoCA)
24
Q

No such thing as a neuropsychological test

A
  • INCORRECT: the results of the cognitive test indicate the cognitive impairment
    + relatively low performance on such tasks could be for many reasons that we don’t understand
  • CORRECT: Only the method of drawing inferences about the tests is neuropsychological
25
Q

Cognitive assessment in educational and vocational settings

A
  • Identify students that may have difficulties in general, or students that are ‘gifted’
  • General cognitive ability (e.g., IQ) is often seen as being predictive of workplace performance
