Hi, I'm Gyan Kumar,
I'm a stroke neurologist at the Mayo Clinic in Arizona.
In this talk, I'll talk about stroke in the young population.
Approximately 10 percent of ischemic stroke occurs in the young population.
Although there is some variability across
studies in the age cut-off for defining young stroke,
generally, stroke in an individual younger than 55 years of age is labeled 'young stroke'.
This talk focuses on ischemic stroke affecting young adults over 18 years of age.
Population and hospital-based registry data have shown that young people who suffer
strokes have a mortality risk that is five-fold, compared to the general population.
Incidence of ischemic stroke has steadily
declined in the older population over the past two decades.
In contrast, incidence is rising in young adults,
as shown by population-based studies.
There has been a decrease in the average age at stroke onset in the young that is
attributable to an increase in the incidence of stroke in this population.
This is also contrary to trends seen with other diseases.
This increase in incidence coupled with a decrease in age at
onset is illustrated by findings from these studies:
a study of nationwide inpatient sample data showed
that the incidence of ischemic stroke hospitalizations rose
from 28 to 38 per 10,000 hospitalizations, over the period of a decade from 1997-2007;
the Greater Cincinnati/Northern Kentucky Stroke Study showed that the proportion of strokes in
the young rose from 13 percent to 19 percent in just over a decade,
while mean age of stroke onset fell from 71 to 69 years;
the Danish registry showed that hospitalizations for ischemic stroke rose from
12 to 17 per 100,000 patient years over a period of just under two decades,
this increase was more pronounced in the recent years;
