Global prevalence of dementia at a young age studied
HealthDay News – According to a systematic review and meta-analysis published online July 19 in JAMA Neurology, the global age-standardized overall prevalence of dementia at a young age (YOD) with symptoms starting before age 65 is 119.0 per 100,000 inhabitants.
Stevie Hendricks from Maastricht University in the Netherlands and colleagues examined the global prevalence of YOD. The systematic review included 95 unique studies, of which 74 with 2,760,379 unique patients were included in 5-year age group meta-analyzes.
The researchers observed an increase in age-standardized prevalence estimates from 1.1 to 77.4 per 100,000 population among 30 to 34 year olds and 60 to 64 year olds, respectively. In the age range from 30 to 64 years, the global age-standardized overall prevalence was 119.0 per 100,000, which corresponds to 3.9 million people aged 30 to 64 years who live with YOD worldwide. In subgroup analyzes, the prevalence was similar for men and women (raw estimates 216.5 and 293.1 per 100,000 population, respectively), but the prevalence was lower in high compared to middle and low-middle income countries (raw estimates, 663 , 9 versus 1,873.6.). or 764.2 per 100,000 inhabitants).

“This systematic overview and meta-analysis estimated the age-standardized prevalence at 119.0 per 100,000 inhabitants worldwide. Although this is higher than previously assumed, it is probably an underestimation due to the lack of high-quality data, ”the authors write. “This should raise awareness among policymakers and healthcare professionals about organizing more and better care for this subgroup of people with dementia.”
