The success ongoing in Finland, anti-Smoking policies can be the main reason that in this country, much less recorded cases of the most dangerous form of stroke — subarachnoid hemorrhage. This was announced by researchers representing the University of Helsinki.

Researchers compared changes in the number of smokers in the country between 1998 and 2012, and also saw how often in this period documented cases of subarachnoid hemorrhage (SAH). As it turned out, the number of smokers aged 15 to 64 years over a fifteen-year period dropped by about 30 percent, and the number of cases of SAH have decreased by 45 percent among women older than 50 years and 26 per cent among men under 50.

Subarachnoid hemorrhage is a hit a large amount of blood in the cavity between the arachnoid and the soft meninges. Often the reason for this is rupture of arterial aneurysm of the brain, emerging approximately every tenth elderly person, but not always represent such a serious danger. According to scientists, in many countries data on the prevalence of this form of stroke is imprecise because often people die from a hemorrhage outside of the hospital, and later the cause of death erroneously referred to as heart failure. However, in Finland, according to researchers, those statistics are significantly more precisely what contributes to the mandatory autopsy.

Although it is conducted by scientists working enables us to establish only a correlation and not a causal relationship between the number of smokers and cases of SAH, in the past a number of the results of several studies already allowed to call Smoking as one of the key factors that increase the risk of this form of stroke. The key role in this, as expected, is not the nicotine, addictive, and other components of tobacco smoke. Thus, scientists believe it is logical to assume that the decrease in the number of smokers really helps to reduce the number of strokes.

The results of their research experts presented on the pages of the journal Neurology.
