Q

What is cognitive reserve?

A

The ability for our brain to “bounce back” through relapse and remission. Eventually, this will catch up with people.

Q

What causes MS (risk factors)?

Study These Flashcards
A
  • environmental factors
  • person factors (gender)
  • immunological factors
  • infectious factors
  • smoking
  • genetic factors
23
Q

If someone is in a risky MS environment and they move locations before 15, what does this in turn do?

Study These Flashcards
A

Decrease their chances of getting MS. Assumes the risk factor of that new place.

24
Q

What percentage of people with MS will self report cognitive difficulties?

Study These Flashcards
A

Approx. 58% of people with MS in Australia. This can be independent of physical symptoms.

25
What are the areas MOST affected in MS?
- processing speed | - complex attention and more
26
Which areas are LEAST affected in MS patients?
- general knowledge - intelligence - basic attention and orientation - language - implicit memory
27
What is a hallmark feature of MS?
thinking speed (speed of processing) due to myelin loss, slowed and irreversible damage to neuron conduction, affects higher-order cognition
28
___ attention is note usually affected in MS, but ___ attention is.
simple (remembering a phone number) | complex (working memory, divided between tasks, sustained attention)
29
What is working memory?
ability to maintain and manipulate information
30
Working memory is highly related to:
processing speed
31
What is one of the most reported symptoms in MS?
long-term memory. Due to learning difficulties rather than retrieval.
32
Learning of 12 words took on average how many trials from people with MS?
8 in comparison to 3 in healthy participants
33
Visual disturbances in MS is generally due to:
optic nerves
34
Visual disturbances can results in difficulties in:
- organising visual information - proprioception - seeing relationships between objects
35
What negatively affects the cognitive decline in MS patients?
- gender - hotter temperatures - disease course (progressive MS) - smoking - cannabis
36
grey matter atrophy is associated with:
cognitive decline
37
What is pseudobular affect, as sometime seen in MS patients?
- uncomfortable laughing/crying | - more intense/out of context
38
What is emotion recognition, as seen in MS patiens?
impaired on fear and anger
39
Theory of mind is ___ affected by MS/
negatively
40
Emotional lability and inappropriate behaviour is seen in __ patient
MS
41
What is MS dementia
severe cognitive impairment due to MS (10% of people with MS)
42
With MS, dementia has to do with issues with ___ while Alzheimer's dementia is more related to ___
learning/encoding | forgetting already learned information.
43
What are two broad things to keep in mind with MS dementia patients?
1. usually takes many years to develop | 2. careful discrete use of term dementia recommended (can be shocking/offensive)
44
What are the aims for medication in relapses
to reduce inflammation | plasma exchange can be used if this doesn't work
45
Drugs that modify MS progression:
- differ for each person - immunosuppressants - immunomodulators
46
What are immune constitution therapies in MS?
-Administered in frequently drug in system for short time -allows immune system to regenerate itself
47
What is stem cell therapy?
- A potential cure for MS? - incredibly expensive - aren't available yet in Australia - 6 stages - takes stem cells out, wipe immune system, put back into body - death rate
48
Which forms of MS are there no medication for?
progressive forms of MS. Drugs only help symptoms.
49
There are currently no medicinal treatments for the cognitive declines associated with MS. What are the most effective "treatments"?
- memory techniques - processing speed techniques (taking time to learn, repeated information) - executive ability techniques - helping manage fatigue
50
What has been shown to be quite effective to manage fatigue in MS people?
CBT
51
Does sleep quality improve cognition in MS patients?
Improves PERCEIVED cognitive ability, but not actual ability
52
Can exercise improve cognition in MS?
conflicting views, however only due to lack of research
53
What did a HIIT exercise groups show in MS patients?
Improved cognition
54
Can gut health improve cognition in MS patients?
No evidence as of yet. However, may help healthy individuals improve some pathways associated with MS.
