The purpose of the study was to assess the impact of environmental factors on the risk of cerebrovascular disease (in the Odessa region). It was shown that the main factors of the risk of developing acute cerebrovascular accident are the fixed life style (69.8%), hypertrophic alimentary status (72.8%), smoking (44.4%) and living in environmentally unfavorable conditions (42.7%). Unsatisfactory conditions for the safety of water supply and contamination of vegetable products by nitrates are registered in 60.5% of patients living in rural areas. These verity of the stroke correlates with the risk of stroke by the MRSC algorithm (r=0.67). In patients with a repeated stroke, the significance of MRSC is higher (81±3 points) than in patients with a stroke that occurred for the first time in life (73±3 points).
