Health threats from high blood pressure.Studies suggest that high blood pressure can lead to mild cognitive impairment. This condition is a transition stage between the changes in understanding and memory that generally come with aging and the more-serious problems caused by dementia. A stroke that interrupts blood flow to the brain can also cause vascular dementia. Narrowed or blocked arteries can limit blood flow to the brain, leading to a certain type of dementia (vascular dementia). High blood pressure can also cause blood clots to form in the arteries leading to the brain, blocking blood flow and potentially causing a stroke. Blood vessels damaged by high blood pressure can narrow, rupture or leak. A stroke occurs when part of the brain doesn't get enough oxygen and nutrients, causing brain cells to die. TIA is often a warning sign of a full-blown stroke. Hardened arteries or blood clots caused by high blood pressure can cause TIA. Sometimes called a ministroke, a TIA is a brief, temporary disruption of blood supply to the brain. High blood pressure may affect the brain in the following ways: The brain depends on a nourishing blood supply to work properly.
