Slightly high BP raises chances of stroke

Washington: Even if your blood pressure ( BP) is slightly elevated, you may be prone to a stroke, new research says.

Prehypertension is a clinical category to describe patients whose

BP is elevated but still considered within normal range. People with prehypertension have a 55 percent higher chance of experiencing a stroke than people without it, University of California School of Medicine noted. That hypertension or abnormally high BP is a major risk for cardiovascular diseases and strokes is well- known, but much less is known about the dangers of prehypertension, the journal Neurology reports. A stroke is a condition where a blood clot or ruptured artery or blood vessel interrupts blood flow to the brain. A lack of oxygen and glucose ( sugar) flowing to the brain leads to brain damage, causing impairment in speech, movement and memory.
