Perceived
Stroke is widely perceived as a disease of the elderly. The dominant cultural image of stroke — a severe event in an 80-year-old — means working-age adults typically assign it a probability close to zero before retirement age. This perception is measurably incorrect. Global Burden of Disease data consistently show that approximately one in four to one in five strokes worldwide occurs before age 65. The underestimation is compounded by the relatively recent recognition that stroke incidence in the 15–49 age band has been rising globally, driven by increasing prevalence of hypertension, metabolic syndrome, and obesity in younger cohorts. Because pre-65 stroke is not the "typical" patient profile, vascular risk factors in working-age adults are undertreated relative to their older counterparts.

Show derivation
Derived from two primary data points. First, Feigin et al. (NEJM 2018), the Global Burden of Disease lifetime-stroke-risk study, estimates lifetime stroke risk from age 25 at 24.9% globally (95% CI 23.5–26.2%). Second, GBD 2021 Stroke (Lancet Neurology 2024) reports that approximately 20–25% of global stroke incidence occurs before age 65. Multiplying: 25% lifetime risk × 22% pre-65 share ≈ 5.5–6.2% cumulative stroke probability before age 65. The 6% headline uses the midpoint. Disability fraction: WHO World Stroke Organization reports ~two-thirds of stroke survivors retain measurable functional disability at 6 months, yielding a disabling pre-65 stroke probability of approximately 4% (0.06 × 0.67 ≈ 0.04). The native and normalized rates (0.06) refer to any stroke before 65; disability fraction is contextual. GBD 2021 confirms rising incidence in 15–49 cohort (+7.6% from 1990 to 2021), making 2026 forward-looking rates likely higher than the baseline implies. Low (0.04): higher-income countries with better vascular risk-factor control and thrombolytic access. High (0.12): Sub-Saharan Africa and Eastern Europe where hypertension control rates are low and stroke incidence in younger adults is rising fastest.
Caveats: The 6% estimate is derived by multiplying lifetime stroke risk (Feigin 2018: 24.…
The 6% estimate is derived by multiplying lifetime stroke risk (Feigin 2018: 24.9%) by the estimated pre-65 share of global stroke incidence (~20–25% from GBD 2021). This is an approximation; direct age-stratified cumulative-incidence-before-65 data are not published in a single global study. Regional variation is large: East Asia has the highest lifetime stroke risk (38.8%); Sub-Saharan Africa and South Asia have rising rates driven by uncontrolled hypertension. High-income countries with strong vascular risk-factor treatment are at the lower end of the uncertainty range. The disability fraction (two-thirds of survivors at 6 months) applies to all-age stroke survivors and may be slightly lower in younger cohorts due to better neuroplasticity and rehabilitation access. The "rising incidence in 15–49" finding from GBD 2021 (+7.6% from 1990) implies forward-looking rates are higher than the 6% baseline. The scope is deliberately global; US-specific data would show a lower rate (~0.04–0.05) due to better hypertension control, but the global figure is more accurate for the majority of the world population.

Global Burden of Disease data for 2021 show that stroke incidence in the 15–49 age band is approximately 49 per 100,000 per year for men and 41 per 100,000 per year for women globally. Combined with Feigin et al.’s (NEJM 2018) global lifetime-risk analysis — which estimated that 24.9% of all adults who reach age 25 will have a stroke in their remaining lifetime — and the finding that roughly 20–25% of global stroke incidence occurs before age 65, the cumulative probability of a stroke before age 65 is approximately 6 in 100 adults worldwide. Of those, approximately two-thirds will retain measurable functional disability at six months. The result: roughly 1 in 25 adults globally is likely to experience a disabling stroke during their working years. In Sub-Saharan Africa and Eastern Europe, where hypertension control rates are lower, rates are substantially higher.
The dominant perception — that stroke is a disease of the elderly — has a measurable clinical consequence: vascular risk factors in working-age adults are systematically undertreated relative to the evidence. Hypertension accounts for approximately 54% of global stroke burden (GBD 2021) and is the most important modifiable risk factor, yet treatment and control rates in people under 50 lag behind older cohorts in nearly every global health system studied. Atrial fibrillation, which raises ischaemic stroke risk four to five times, is also increasingly common in the 40–65 cohort as metabolic syndrome and obesity rates rise. The mismatch between perceived risk (near-zero in working adults) and actual risk creates a predictable gap in primary prevention.
A critical trend embedded in the GBD 2021 data is direction: stroke incidence in the 15–49 age group increased by 7.6% between 1990 and 2021 globally, while incidence in older age groups was declining in most high-income countries due to improved cardiovascular prevention. The epidemiological profile of stroke is shifting younger, driven by earlier onset of the metabolic risk factor cluster. The 6% pre-65 estimate is therefore a conservative current baseline — forward-looking rates may be higher if the trend continues and preventive coverage in younger adults does not improve.

Global, regional, and national burden of stroke and its risk factors, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021- Statistic
Stroke incidence in 15–49 age group globally: 49.15/100,000/year men, 41.4/100,000/year women (GBD 2021); ~14% of all stroke incidence under age 50; rising trend +7.6% 1990–2021- Excerpt
“"In 2021, the age-standardised incidence rate of stroke for the 15–49 age group was 49.15 per 100,000 population per year for men and 41.44 per 100,000 per year for women globally. Approximately 14 percent of all stroke incidence worldwide occurred in individuals under the age of 50, with the proportion rising over the study period (1990–2021). The age-standardised incidence rate in this younger group increased by 7.6 percent between 1990 and 2021, driven predominantly by increases in metabolic risk factors including hypertension, obesity, and diabetes in younger cohorts." ”

- GBD 2021 Stroke systematic analysis, Lancet Neurology 2024. The 49.15/100k and 41.44/100k annual incidence rates for 15–49 provide the primary denominator for the pre-65 calculation. The "14% of all stroke incidence under 50" figure, combined with the Feigin 2018 lifetime-risk data, anchors the cumulative 6% pre-65 estimate. The rising incidence trend (7.6% 1990–2021) implies the 6% baseline is a conservative current estimate.

Lifetime stroke risk from age 25: 24.9% globally (95% CI 23.5–26.2%); 1 in 4 adults worldwide will have a stroke in their remaining lifetime from age 25- Excerpt
“"The lifetime risk of stroke from age 25 was 24.9% (95% CI 23.5–26.2%) globally, with substantial regional variation — highest in East Asia (38.8%) and lowest in sub-Saharan Africa (11.8%). Risk estimates were calculated using GBD 2016 incidence, prevalence, and mortality data. Among those who survive to older ages, the lifetime risk from age 70 was 13.6%. These data indicate that stroke is an extremely common event across the global adult population." ”

- Feigin et al. NEJM 2018 — global lifetime stroke risk from GBD 2016. The 24.9% lifetime risk from age 25 is the denominator for calculating the pre-65 share. Combined with the GBD 2021 finding that ~20–25% of stroke incidence occurs before age 65, yields a cumulative pre-65 stroke probability of approximately 5–6%. This is used as the native rate (6/100).

~two-thirds of stroke survivors globally retain measurable disability at 6 months; stroke is the second leading cause of disability globally- Excerpt
“"Globally, approximately two-thirds of stroke survivors retain some degree of measurable functional disability six months after their stroke. Stroke is the second leading cause of disability globally, behind only ischaemic heart disease. In younger stroke survivors (under 65), return to work and independent living are achievable for many, but long-term disability rates remain high: studies from high-income countries show 30–50 percent of working-age stroke survivors are unable to return to their pre-stroke employment within one year." ”
