More than 20 million people living with dementia
China had 20,299,243 people living with Alzheimer's disease and other forms of dementia in 2023, accounting for 33.75 percent of the worldwide total of 60,154,121, according to The China Alzheimer Report 2026. An earlier official report, released in 2024, put China's share at nearly 30 percent and its number of affected people at more than 16 million in 2021.

The latest figure means roughly one in every three people living with dementia worldwide was in China. Subtracting China's total from the global figure leaves about 39.85 million people across the rest of the world, or roughly two people elsewhere for every person affected in China.
For families, the numbers describe a condition that can gradually change everyday life: remembering appointments, managing money, preparing meals and eventually carrying out basic personal tasks. For China, they point to demand for medical assessment, continuing treatment and care that extends well beyond hospitals.
China has already announced a national action plan involving 15 institutions, including the National Health Commission and the National Development and Reform Commission. Its central target is to establish a continuous system covering prevention, screening, diagnosis, treatment, rehabilitation and care by 2030.
The scale of the challenge is growing alongside population ageing and a falling birth rate. More people are reaching ages when dementia becomes common, while smaller younger generations may have to support more older relatives. The practical test is whether services can reach people early and continue supporting them as their needs change.
What the figures actually count
The 20.3 million figure covers Alzheimer's disease and other dementias together. Dementia is a broad term for a decline in memory, thinking and other mental abilities serious enough to interfere with daily life. Alzheimer's is the most common disease that causes it.
A person with occasional forgetfulness does not automatically have dementia. Doctors assess the pattern of symptoms, their effect on daily activities and possible causes. Different diseases can produce similar difficulties, which is one reason a proper diagnosis matters.
The China Alzheimer Report 2026 describes people living with these conditions in 2023. Its publication title and the year measured are different: the figure is a picture of the burden in 2023, rather than a count for 2026. The same distinction applies to the official report published in 2024, which gave a national figure for 2021.
The information accompanying the latest total does not specify how the cases were counted or estimated. Readers therefore have a precise reported number, but no accompanying explanation here of the surveys, records or statistical methods used to produce it.
China's 33.75 percent share also answers a different question from an individual's risk of developing dementia. It describes how the world's cases are distributed between countries. Assessing risk within China would require population figures and information about age, because dementia becomes more common as people grow older.
Why screening is a central concern
Shi Jiong, a dementia expert, has described Alzheimer's disease in China as having high prevalence alongside low rates of screening, diagnosis and treatment. Put simply, many people are affected, while too few pass through the steps that connect symptoms with medical attention and continuing care.
Screening is an initial check for possible problems with memory or thinking. It helps identify people who need a fuller assessment. Diagnosis is the next, more detailed process of determining what is causing the difficulties and what support or treatment is appropriate.
China's action plan calls for widespread cognitive function screening among older people and early intervention for those at risk. It also calls for more consistent diagnosis and treatment services. Together, these measures aim to connect the first signs of difficulty with a route into care.
For an older person and their family, that route can be consequential. Recognising difficulties earlier can create time to discuss daily support, medication management, household safety and future care arrangements. The plan's attention to screening addresses the beginning of that process; its treatment and care provisions address what follows.
A national plan covering the full course of care
The 15 institutions behind the action plan have set out seven key tasks and a series of targets for 2030. The named priorities include screening and early intervention, standardising diagnosis and treatment, and expanding services for older people with dementia.
The proposed system covers six connected areas: prevention, screening, diagnosis, treatment, rehabilitation and care. Each serves a different purpose. Prevention aims to reduce risk where possible, treatment addresses the diagnosed condition, rehabilitation supports a person's abilities, and care helps with daily needs.
A continuous system means that a person identified through screening should have a route to further assessment and, when needed, treatment and longer term support. Families often have to navigate these stages over several years as a person's condition changes.
The plan also seeks to control the growth rate of dementia prevalence. That objective concerns how quickly the burden grows. With China's population ageing, services will still need to prepare for substantial demand while prevention and early intervention measures are developed.
The announced timetable places the main targets in 2030. No intermediate national deadlines or progress figures are given in the announcement described here, leaving implementation and the expansion of local services as the next developments to watch.
Two care targets with different meanings
By 2030, the plan proposes dedicated dementia care units in 50 percent of elderly care institutions that have more than 100 beds and adequate service capabilities. The qualifying conditions matter: the target applies to a specified group of institutions, rather than every elderly care home in China.
For residents, a dedicated unit can mean an environment and staff organised around dementia care. People whose memory, judgement or ability to communicate have changed may need different supervision and assistance from residents whose main needs are physical.
The second target is a cumulative total of 15 million trained dementia care personnel by 2030. The word cumulative means training is counted over time. The target describes the scale of the training effort; the announcement gives no corresponding figure for how many trained workers will be employed in dementia care at any one time.
These two commitments address different parts of the same problem. Care units provide places and organised services, while training builds the skills needed to support people. Families will experience progress through practical details such as whether an appropriate service is nearby, whether it has capacity and whether staff can respond to changing needs.
The plan's care provisions also extend the focus beyond diagnosis. A medical appointment can identify a condition, but a person may need help every day afterward. Expanding that support is central to the burden facing households as well as health services.
How the evidence and policy timeline fit together
Chinese researchers were documenting national data and prevention strategies before the latest headline figure. The Journal of Alzheimer's Disease and Related Disorders published 2023 Data and Strategies, an academic article by Xu Yong, Wang Jun and colleagues on Alzheimer's disease in China.
The article appears in volume 6, issue 3, on pages 175 to 192. Its listing gives July 25, 2023, as the publication date and October 19, 2023, as the issue date. It represents an earlier academic effort to bring national data and prevention and control strategies into the same discussion.
The main milestones show why the dates attached to the figures deserve attention:
- 2021: China had more than 16 million people with Alzheimer's disease and other dementias, according to the official report released in 2024.
- 2023: The year measured by The China Alzheimer Report 2026, which gives a national total of 20,299,243 people.
- 2024: An official report published the earlier national burden figures.
- 2030: The action plan's deadline for a continuous dementia prevention and care system and its institutional care and personnel training targets.
The earlier total and the latest figure both show a large national burden. Calculating a precise increase between them would require a more exact starting figure and information about whether the same counting methods and definitions were used.
What changes for families and services
China's combination of an ageing population and fewer births puts dementia care within a wider challenge of supporting older people. Hospitals, community services and elderly care institutions all have roles, while relatives may have to organise appointments, supervise daily routines and make decisions as abilities decline.
The action plan brings these needs into a single national framework. Its value for a household will depend on connections between services: access to screening, an assessment after a concerning result, appropriate medical care and help when independent living becomes difficult.
The latest figure also gives the effort a global dimension. With China accounting for about a third of people living with Alzheimer's and other dementias, improvements in access to care there would reach a substantial share of everyone affected worldwide.
The immediate priorities are concrete: reach people who have not been assessed, make diagnosis and treatment more consistent, and expand care capacity. The 2030 targets provide a timetable against which those changes can be assessed.
