The main questions were answered:
Q: How long does it usually take to diagnose dementia?
A: On average, 3.5 years of identifying the first symptoms-4.1 years for early cases.
Q: What are the factors that delay the diagnosis?
A: The younger age, the front dementia, systemic health care issues, and the stigma.
Q: Why does it not matter the diagnosis in time?
A: Early diagnosis improves access to treatments and prolongs the quality of life during the early stages.
summary: A global analysis revealed that people with dementia are waiting on average 3.5 years after symptoms appear before the diagnosis is received. The delay is longer -4.1 years-for early decorating, with younger patients and those who suffer from the front dementia in the face of the greatest delay.
Factors include the misplaced symptoms as natural aging, limited access to specialists, stigma stigma, and suffocation of a health care system. Researchers request urgent reforms to improve doctors training, public awareness, and diagnostic infrastructure around the world.
Main facts:
- Long delay: It takes 3.5 years of dementia to diagnose after the start of the symptoms.
- Younger patients at risk: Early and younger individuals face longer delays, with an average of 4.1 years.
- Barriers of diagnosis: The stigma of shame, lack of awareness, specialized leaks, and all regular issues contribute.

People with dementia are diagnosed at a rate of 3.5 years after observing symptoms first, or even longer (4.1 years) for those who suffer from an early dementia, finds a new study led by researchers at UCL.
The study, published in International Journal of Psychiatry AgingIt is the first systematic review and angry analysis of global evidence that taught time to diagnose dementia.
The researchers reviewed the data of 13 pre -published studies that took place in Europe, the United States, Australia and China, and reported about 30257 participants.
The research team was investigating the average interval between the appearance of symptoms (classified by patients or family care providers who use interviews or medical records) to the final diagnosis of dementia.
The lead author, Dr. Vasiliki Orgita (UCL Department) said: “Timely diagnosis of dementia is still a major global challenge, formed by a complex set of factors, and specific health care strategies are diagnosed significantly to improve them. Other studies can only be that only 50-65 % of cases are diagnosed in high-income countries, with many countries that have diagnostic rates Low.
“Timely diagnosis can improve treatments, and for some people lengthen time to live with moderate dementia before symptoms are aggravated.”
In the complex of the complex of 10 of the studies covered, the researchers found that it usually takes 3.5 years of the first alert from symptoms to a patient receiving a diagnosis of dementia, or 4.1 years for those who suffer from early dementia, with some groups more than longer delay.
They found that the younger age was at the beginning and with the front -front dementia was longer for diagnosis. While the data related to ethnic variations was limited, one of the studies that were reviewed found that black patients tend to have a longer delay experience before the diagnosis.
“Our work sheds light on the need for a clear conceptual framework at the time specified for diagnosis in dementia, which was developed in cooperation with people with dementia, care providers and supporters,” said Dr. Urugta.
“Symptoms of dementia are often wrong in natural aging, while fear, stigma and low public awareness can discourage people from seeking help,” said Dr. Fong Lyong (UCL).
“In health care systems, inconsistencies, limited access to specialists, and memory clinics that transport resources to increase delay can lead,” said Professor Rafael Del-Beno Casado, from Jain University, Spain.
“To accelerate the diagnosis of dementia, we need a procedure on multiple fronts. Public awareness campaigns can help improve the understanding of early symptoms, reduce the stigma, and encourage people to seek help sooner.
“Training doctors is very important to improve early recognition and referral, as well as access to early intervention and individual support so that people with dementia and their families can get the help they need.”

It is time to diagnose dementia: a systematic review with a twist analysis
Timely diagnosis is a global priority, reflected in most national and regional policies and plans.
However, there are currently no strong estimates of the average time for diagnosis (TTD) and factors that affect diagnostic periods.
This article displays the first systematic review of quantitative studies on TTD in dementia and factors associated with a period.
We systematically searched the Embase, Medline and Cinahl databases for relevant studies that were published until December 2024. We have identified TTD as the interval between the beginning of symptoms (the classification of family care providers or patients who use interviews or medical records) to the final diagnosis.
The risk of bias is evaluated using reports studies on time for the diagnostic tool. We included 13 studies that we have reported about data for 30257 participants, with age at the beginning of 54 and 93 years.
Analytical analysis showed the collection of 10 studies that the average TTD in all types of dementia was 3.5 years (CI): 2.7-4.3; moderate quality evidence).
Six studies showed that TTD in the appearance of young dementia was 4.1 years (CI: 3.4-4.9; moderate quality evidence). Although the factors that affect TTD were inconsistent, the age of the younger at first and a recognition of the temporal front dementia was constantly associated with a longer period of time for diagnosis.
TTD remains in dementia long, and needs urgent health care strategies to improve it. Increasing the base of evidence and developing interventions to reduce TTD should be a future research priority.
Specialized services are likely to be a key to improving TTD in young dementia.
