If we take these facts into consideration it is no wonder that fear of a stroke is very high amongst the population. In general it is described as a faulty blood supply to the brain and the consequences are that various functions of the central nervous system fail in the form of a stroke. This happens suddenly and seems to come from nowhere, although medical science is aware of the risk factors and the precursors.
The first symptoms can be the restriction of vision, vertigo/dizziness, paralysis, numbness, speech defects, headache or a sudden loss of orientation. All of these symptoms can be the first signs of a stroke, but of course also point to other conditions too. If several of these symptoms occur then this could be an indication of a stroke.
