what are the causes of stroke?

In France, more than 120,000 people are hospitalized every year after a stroke. And this figure is probably underestimated, because a small stroke can go unnoticed. “We already knew that pollution, in particular by fine particles, increased the risk of migraine and neurodegenerative diseases such as Alzheimer’s or Parkinson’s, but Japanese researchers wanted to know if chronic exposure to air pollution did not make us more vulnerable. in the event of a stroke”explains the journalist and doctor Damien Mascret, present on the set of 12/13 this Friday, May 12.

The researchers took two groups of mice, one of which was subjected to the equivalent of Beijing pollution for a week, and caused them to have a stroke. Those who bathed in pollution had much more serious strokes and poorer recovery.

Tobacco and alcohol, aggravating factors

It would appear to be the same in humans,”because many clues point in this direction, but there are other risks that we can already avoid”. The first is not to smoke, because smoking increases the risk of stroke by 197%. It is recommended to play sports, regular physical activity reduces the risk of stroke by 26%. As for alcohol, with one drink a day, “the risk of cerebral hemorrhage is increased by 50%”. It is also a risk if one does not occasionally overindulge. With “more than 5 glasses at least once a month, the risk of bleeding increases by 59%”, concludes the journalist.
