week 8 Flashcards
2017 lancet report mentioned 9 potentially modifiable risk factors for dementia: name the first 5
less education, hypertension, hearing impairment, smoking, and obiesisty
what are the four others?
physical inactivity, diabetes, depression, and low social contact
Education and dementia:
Higher Childhood education levels and lifelong educational attainment and lower dementia risk
What is hypertension, and what is its effect on dementia
hypertension is elevated blood pressure
Persistent midlife hypertension is associated with increased risk of a late life dementia.
Hearing impairment and dementia: A 25-year prospective study of 3777 people aged 65 years or older found
increased dementia incidence in those with self-reported hearing problems except those using hearing aids
Hearing loss is the
The number one predictor of dementia
Smoking and dementia: stopping smoking for more than 4 years
substantially reduced dementia risk
Obesisty and dementia:
Research shows that increased BMI and dementia are linked.
Obesity but not being overweight was associated with
late life dementia
physical inactivity and dementia: at least weekly midlife moderate to vigorous exercise was associated with
reduced risk of dementia over a 25 year follow up period
Diabeties as a risk factor for dementia
the risk for dementia increases with the severity of diabetes
diabetes medication:
research has shown that it can be a risk or a protective facto. data is inconclusive
Depression and dementia incidence:
psychological distress predicted dementia 25 years later
depression and dementia: corralation
it may be the case that early dementia could be the cause of depression, not the other way around
Social contact and dementia:
it is a protective factor against dementia. It enhances cognitive reserve or encourages beneficial behaviours
The 2020 study added three more modifiable factors that may cause dementia:
excessive alcohol, traumatic brain injury, and air pollution
Excessive alcohol consumption and dementia: heavy drinking is associated with (3) things
cognitive impairment, brain changes and dementia
Alcohol use disorder in men and women and dementia
greatly associated with increased dementia risk
traumatic brain injury and dementia: what is TBI
concussions or skull fracture, brain bleeds
Dementia risk was highest when after TBI?
6 months after
Air pollution and dementia: air pollutants are associated with
neurodegenerative processes. No2, concentration and woof burning are all associated with higher risk dementia
What are the 4 types of dementia and their prevalence?
alzihmers disease_ 60-70%
frontotemporal dementia- 10%
Lewy body dementia-5%
vascular dementia-10-20%
Interventions once a diagnosis has been made: (3)
medications, cognitive training, exercise and physical activity
