Despite the slightly different causes of a stroke, the common theme is that strokes occur when the brain is starved of oxygen. If the supply of blood is restricted or stopped, brain cells begin to die. This can lead to brain injury, disability and possibly death.
A wake-up stroke is generally considered to have the same causes as other types of stroke, but researchers have identified a few factors that may put individuals at risk of having a wake-up stroke in comparison to a stroke that occurs when the individual is awake.
These risk factors include:
- Sleep disorders
- blood pressure
- cholesterol levels
In fact, the role of sleep disorders and wake-up strokes is still an active area of research for experts. According to a study published back in 2021 in the American Heart Association journal, researchers found sleep problems were more likely to occur among women, smokers, people with other health conditions and those who have strokes at older ages.
