Key Takeaways
- 10/66 dementia prevalence is estimated at 6.7% for dementia in high-income countries (used as a benchmarking base for Alzheimer’s share among dementias in the study’s modeling)
- Alzheimer’s disease is the 6th leading cause of death in the United States
- An estimated 10 million new cases of dementia occur each year globally
- Dementia is estimated to be responsible for 1% of the global burden of disease and 2% of deaths globally when measured using disability-adjusted life years (WHO estimate)
- Alzheimer’s disease and related dementias (ADRD) contributed an estimated 3.4% of global disability-adjusted life years attributable to neurological disorders in 2019 (GBD-based modeling as reported in the Lancet Neurology ADRD meta-reporting)
- In the U.S., the Alzheimer’s Association estimates a 25% reduction in Alzheimer’s disease prevalence over 25 years could save $26 billion per year (modeled economic impact using the cost framework)
- Dementia-related out-of-pocket spending was estimated at $20.3 billion in the U.S. in 2020 (as part of the cost-of-dementia breakdown)
- 44.9% of total dementia costs in high-income countries are informal care (a share reported by the Global Burden of Disease dementia cost modeling framework)
- The global Alzheimer’s disease therapeutics market is expected to post a CAGR of 7.6% from 2024 to 2032 (market research forecast)
- $65.1 billion is the projected global Alzheimer’s disease diagnostics market size by 2030 (MarketsandMarkets forecast)
- $18.3 billion is projected market value for Alzheimer’s disease therapeutics by 2030 (Precedence Research forecast)
- On ClinicalTrials.gov, there are over 1,200 Alzheimer’s disease interventional studies as of May 2024 (query results are dynamically generated; use a snapshot link)
- In 2021, NIH funded 3,500 Alzheimer’s disease-related projects (NIH RePORTER output count for Alzheimer’s disease query)
- In the Clarity AD trial, the mean Clinical Dementia Rating–Sum of Boxes (CDR-SB) change was 0.45 points lower with treatment than placebo at 18 months (reported efficacy result)
- In the EMERGE trial, the proportion of participants who achieved amyloid plaque reduction to low levels was 47% with treatment versus 19% with placebo at 18 months (reported imaging outcome)
Alzheimer’s and related dementia affect millions worldwide and drive major deaths, costs, and research urgency.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
