Stroke eight times frequent in adults with insomnia

The risk of stroke may be much higher in people with insomnia compared to those who do not have trouble sleeping, a new research has claimed.
The risk also seems to be far greater when insomnia occurs as a young adult compared to those who are older, said researchers who reviewed the randomly-selected health records of more than 21,000 people with insomnia and 64,000 non-insomniacs in Taiwan.
They found Insomnia raised the likelihood of subsequent hospitalisation for stroke by 54 per cent over four years.
The incidence of stroke was eight times higher among those diagnosed with insomnia between 18-34 years old. Beyond age 35, the risk continually decreased.
The mechanism linking insomnia to stroke is not fully understood, but evidence shows that insomnia may alter cardiovascular health via systematic inflammation, impaired glucose tolerance, increased blood pressure or sympathetic hyperactivity, researchers said.
Some behavioural factors (eg, physical activity, diet, alcohol use and smoking) and psychological factors like stress might affect the observed relationship.
The research was published in the American Heart Association journal Stroke.
