Stroke (cerebrovascular disease)

A stroke (Heart & Stroke Foundation) refers to a problem of circulation (blockage) in the blood vessels of the brain. Sometimes the stroke involves a partial blockage causing temporary effects, or a complete blockage with long-term effects. Vessels in the brain may also burst causing long-term effects.

Stroke hospitalizations by geographic area

Key findings:

In the Sudbury & District Health Unit (SDHU) area, there were 333 hospitalizations due to stroke in 2013.
In 2013, the rate of hospitalization due to stroke in the SDHU area was 139 hospitalizations per 100,000 population.
The rate of hospitalization due to stroke in the SDHU area has been generally similar to that in northeastern Ontario, while the rates in both areas have consistently been higher than the rate in Ontario.
Between 2004 and 2013, the rate of hospitalization due to stroke in the SDHU area has generally decreased.

Notes:

Rates are age-standardized using the 2006 Canadian population.
