Scientists have named the main danger of Smoking.
Finnish scientists have found that tobacco policy can significantly reduce the incidence of subarachnoid haemorrhage (the most lethal form of stroke). The results published in the journal Neurology.
Doctors assessed the incidence of stroke over a period of 15 years (1998-2012). It turned out that the frequency of hemorrhages was in direct proportion to the number of smokers. The number of people affected by stroke have declined by 45 percent among women older than 50 years and 26 percent among men of the same age. The number of smokers aged 15-64 years in Finland decreased by 30 percent.
According to scientists, the results do not show a causal relationship, but it is highly likely that the efforts of the authorities to combat Smoking influenced the incidence of subarachnoid hemorrhage.
Subarachnoid hemorrhage is the accumulation of blood streamed into the cavity between the arachnoid and the soft meninges. It can develop due to rupture of arterial aneurysm or traumatic brain injury. Aneurysm of cerebral vessels is present in 10 percent of people older than 70 years, but in most case it is not terminated. While studies have shown that Smoking is one of the most important risk factors of hemorrhage.
