Stroke Incidence Among Adults 20-54 Nearly Doubles Over Three Decades
A new study shows that first-time strokes in people aged 20 to 54 have almost doubled between the early 1990s and 2020, while short-term survival has modestly improved.
A regional analysis of stroke cases from 1993-2020 revealed that first-time strokes among adults aged 20-54 increased by roughly 83%, climbing from 33.9 to 62.2 per 100,000 person-years. The surge was almost entirely due to ischemic strokes, whose rate rose from 23.8 to 47.3 per 100,000 person-years, while hemorrhagic stroke rates stayed flat. Over the same period, the prevalence of high blood pressure, diabetes, atrial fibrillation and substance use - notably marijuana - grew markedly among stroke patients, though the study could not prove causation.
Survival improved, with 30-day death rates dropping from 11.7% to 9.4%, especially for bleeding strokes. Nonetheless, survivors may endure lasting impairments in movement, speech or cognition. Study lead Emily R. Fisher emphasized the need for early risk-factor management and further research to explain the trend. The work was supported by the Greater Cincinnati/Northern Kentucky Stroke Study and published in Neurology.
