Early onset dementia is less common than late onset dementia, the former accounting for approximately 10% of dementias globally. [3] Recent studies estimate the prevalence of early onset dementia to be approximately 3.55 million people aged 30–64 worldwide, and will triple by 2050. [6] with an incidence of 119 per 100,000 individuals. [1]
It accounts for 50% of all dementias in Japan, 20% to 40% in Europe and 15% in Latin America. 25% of people with stroke develop new-onset dementia within one year of their stroke.

[ 276 ] [ 277 ] Less than 1% of those with Alzheimer's have gene mutations that cause a much earlier development of the disease, around the age of 45, known as early-onset ...
Frontotemporal dementia (FTD) is an early onset disorder that mostly occurs between the ages of 45 and 65, [13] but can begin earlier, and in 20–25% of cases onset is later. [11] [14] Men and women appear to be equally affected. [15] It is the most common early presenting dementia. [16]
