Q

what is the ecological representation of approach 2?

A

includes almost all co-morbidities and mixed

24
Q

what is the rationale behind approach 2?

A

difficult to specify criteria and detect pure disease cases

25
what is the limitation to approach 2?
heterogeneity within diagnostic groups
26
what is NDD diagnosis approach 3?
moderate application of inclusion and exclusion criteria
27
what is the compromise with approach 3?
"rather broad" criteria: produce less homogenous groups that represent most of dementia pop
28
who is represented in approach 3?
co-morbidities and mixed dementias
29
are all mixed diseases included in approach 3?
no only most
30
who will be excluded from approach 3?
brain disease major psychiatric disturbance drug addiction
31
what model did Kaarin Ansety create?
CHELM
32
what does CHELM stand for?
cognitive health environment lifecourse model
33
what approach is close to CHELM?
CLASS
34
why is the CHELM approach similar to CLASS?
- core ideas in brain/cog aging and dementia - importance of longitudinal approaches - adding multi-modal RF to DPM
35
what is the overlap and relatedness between CHELM and CLASS?
differential changes, intra-individual, mechanisms, plasticity cascades of risk (broader focus)
36
what are the 2 types of reserve capacity?
brain: passive, cognition affected after accumulation of pathology cognitive: active, cognition continues despite brain pathology
37
what is the chain for the CHELM model?
biomarkers to RF -> controllable RF -> modifiable RF -> bio-clinical outcomes -> prism of neurocognitive resources -> cognitive or clinical outcomes
38
what is the Lancet Commission?
comprehensive review - life course projection
39
how many modifiable RFs are there?
12 - education - hearing loss - hypertension - obesity - alcohol/tbi - smoking - depression - physical inactivity - social isolation - diabetes - air pollution
40
what are the 3 identified mechanisms of ND risk?
- reduction in brain/cognitive reserve/resilience - increasing brain damage as a fxn of disease and insult - spreading brain inflammation
41
what is the goal of the Lancet?
aim for reducing specific RF in order to modify risk mechanisms
42
what is Anstey's "umbrella review"?
systematic review of world-wide evidence on RFs of dementia
43
what are the 3 conclusions from Anstey's review?
- evidence base varies by NDD - lack of "early" effect evidence - much variability in geographical representation of evidence
44
what is the IRNDP?
international research network on dementia prevention - how systematic and diverse studies of RA can contribute to understanding differential pathways toward or away from ADRD
45
who founded IRNDP?
Anstey
46
what is the purpose of the risk assessment?
allows for early detection of risk and for application to RCTs and RR protocol
47
what are the 6 health factors contributing to vascular risk for unhealthy brain aging and dementia?
stroke obesity smoking high cholesterol hypertension diabetes
48
what are the 4 points from CULTURAL?
- need for cross-national and cultural investigations - need for linking RFs with associated mechanisms - need for harmonization - exploring new research targetsw
49
what is the summary of CULTURAL?
scientific, ethical, and practical imperative to expand dementia risk and prevention research across nations, cultures, regions and under-represented populations
50
what are the 4 directions for the IRNDP research?
- expand diversity research - expand attention to life course exposure variations - expand evidence base - expand long-term follow-up research
51
what are some social determinants of health affecting degree of or access to potential RF change?
- income and social status - education and literacy - employment and working conditions - early childhood development - physical environment and housing - social supports - access to health services - biology and genetics - gender - culture - race - disability and ableism
52
what is the principle of SSDH?
person's social and structural "context" affects RF, RR, possibilities for modifying risk or protection
53
what are SSDH?
non-medical, social, and economic factors that occur within everyday and working conditions of people and substantially influence the extent and direction of dementia risk
54
what are the challenges of SSDH?
modifiable RF and PF do not operate uniformly or universally, but only within the SSDH context of individuals
55
what is the implication of SSDH?
effectiveness of interventions to modify RFs and PFs depend on SSDH context
56
what are the communities of dementia and dementia risk?
- indigenous - growing # of older Ind and impacts of social determinants of health - racialized - ethnic profile of older people is growing - sex and gender - chronological age - early onset poses a challenge
57
what is the Tom Kitwood quote?
when you've met one person with dementia, you've met one person with dementia
