Q

What is the MMSE?

A

used to screen for dementia
- scored out of 30
- if score is less than 24 = IMPAIRED
- asks questions about:
a. orientation
b. registration
c. attention and calculation
d. recall
e. language
f. visuospatial abilities

Q

What 4 things must be present in order to diagnose AD?

A
  1. memory impairment (amnestic presentation)
  2. impairment in at least one other cognitive domain/ “nonamnestic presentation” (language, visiospatial, executive)
  3. insidious onset –> gradual onset NOT rapif
  4. clear-cut history of worsening condition
17
Q

Can AD cause personality changes?

A

YES

18
Q

What are the 4 risk factors of AD?

A
  1. age (#1 RISK FACTOR)
  2. heredity
  3. mild cognitive impairment
  4. health status (high BP, cholesterol, diabetes)
19
Q

What is one protective factor of AD??

A

EDUCATION!!! —> increases your baseline

20
Q

What 5 things are important to diagnosis of dementia?

A
  1. interfere with the ability to function in everyday life
  2. decline from previous levels
  3. not explained by other psych disorders
  4. detected by combo of history taking and objective cognitive assessment
  5. impairment in minimum TWO of following domains
    - ability to acquire and remember new info
    - reasoning and handling complex tasks
    - visuospatial abilities
    - language function
    - personality
21
Q

What 3 genetic mutations are possibly linked to early onset-AD?

A
  1. APP
  2. PSEN1
    3.PSEN 2
22
Q

How can we treat mild to moderate AD?

A

cholinesterase inhibitors (“Aricept”)

  • prevent breakdown of acetylcholine (helps with memory!)
23
Q

How do we treat moderate to severe AD?

A

drug called “Namenda” or “memantine”

  • NMDA anatagonist
  • regulates glutamate
24
Q

Are the side effects of most AD meds intense?

A

YES! (diarrhea, vomiting, fatigue, muscle cramps)
“walls…the walls” - Profs friend’s quotes

25
Q

What do astrocytes do?

A

clear away debris and keep neurons healthy

26
Q

Can it take years before first signs of dementia?

A

YES!

27
Q

Which part of the brain does neural loss begin?

A

Hippocampus

28
Q

Besides drugs, what can be done to treat AD?

A
  • lifestyle interventions!
29
Q

What is a gold standard indication that someone has AD?

A

problems with ORIENTATION (person, place, time)
