What is the relationship between high blood pressure and dizziness?

The relationship between blood pressure and dizziness is interesting in many ways. In serious cases, blood pressure abnormalities, when the blood pressure is very high, can lead to stroke, for instance. And a stroke can affect parts of the brain that lead to intense dizziness and vertigo. And it is also possible that in old patients who've had high blood pressure for a long time, the blood pressure has caused abnormalities of widespread parts of the brain that are responsible for moving the legs or coordinating the legs properly. And so, this sense of incoordination in the legs can make them feel dizzy. And finally, and perhaps the more common aspect is people whose blood pressure drops when they stand up or when they move about, that dropping blood pressure will make them feel dizzy.
