2022 Alzheimer's disease facts and figures
Alzheimer's & dementia : the journal of the Alzheimer's Association, 2022-03-14
Topic: Amyloid, tau and blood-test diagnosis
This article describes the public health impact of Alzheimer's disease (AD), including incidence and prevalence, mortality and morbidity, use and costs of care, and the overall impact on family caregivers, the dementia workforce and society. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Its costs, however, extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes - costs that have been aggravated by COVID-19. A recent survey commissioned by the Alzheimer's Association revealed several barriers to consumers' understanding of MCI. Survey results indicate the need to improve MCI awareness and diagnosis, especially in underserved communities, and to encourage greater participation in MCI-related clinical trials.

Key findings
- This article describes the public health impact of Alzheimer's disease (AD), including incidence and prevalence, mortality and morbidity, use and costs of care, and the overall impact on family caregivers, the dementia workforce and society.
- These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver.
- Its costs, however, extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes - costs that have been aggravated by COVID-19.
- A recent survey commissioned by the Alzheimer's Association revealed several barriers to consumers' understanding of MCI.
- Survey results indicate the need to improve MCI awareness and diagnosis, especially in underserved communities, and to encourage greater participation in MCI-related clinical trials.
Why it matters
This 2022 report describes the public health burden of Alzheimer's. It says there are fewer family caregivers than a decade earlier, each one provides more care, and caregivers face an increased risk of emotional distress and poorer mental and physical health, which the report says COVID-19 made worse. A survey commissioned by the Alzheimer's Association found barriers to public understanding of mild cognitive impairment, and the report calls for better awareness and diagnosis, especially in underserved communities. The page gives no figures and tests no treatment, so it describes the problem rather than showing what reduces it.

How this study scored 57/100
Published in a leading specialty journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on senior author's track record and institution's track record, so those were left out: it earned 53 of the 93 points we could judge it on, which is 57 out of 100.
