TEHRAN (FNA)- Researchers in Hong Kong have found out that most brain strokes appear to occur more frequently during the coldest months of winter.
The researchers stated that such strokes, called aneurysmal subarachnoid haemorrhage, peak in January.
"It is the most fatal type of brain haemorrhage, with a mortality of 50 percent," George Wong, associate professor at the Prince of Wales Hospital's neurosurgery division said on Friday.
"The incidence is higher in winter, which correlates with changes in atmospheric pressure," press tv quoted him as saying.
According to Wong, such strokes are more common in patients with hypertension and smokers.
"The two messages we want to bring out are for people to be more aware of weather conditions and for people to control their blood pressure and, of course, quit smoking," he noted.
The research team from Hong Kong's Prince of Wales Hospital studied records of 135 patients who suffered this form of stroke from October 2002 to October 2006.
The findings of the new research are published in an article in Friday's edition of Hong Kong Medical Journal.
