Lack of dopamine at key sites in the brain may increase blood pressure and/or trigger depression (6). Furthermore, the cerebrovascular and ischemic changes in the brain promoted by high blood pressure may predispose individuals with hypertension to depression (9).

But sometimes blood pressure rises so quickly and severely that it becomes a medical emergency requiring immediate treatment, often with hospitalization. In these situations, high blood pressure can cause: Memory loss, personality changes, trouble concentrating, irritability or progressive loss of consciousness.

High blood pressure transforms cells of the immune system that reside around cerebral blood vessels and normally protect the brain into agents of cognitive decline, according to new research from Weill Cornell Medicine scientists.

High blood pressure is a major risk factor for heart disease. It is a medical condition that happens when the pressure of the blood in your arteries and other blood vessels is too high. The high pressure, if not controlled, can affect your heart and other major organs of your body, including your kidneys and brain.

High blood pressure, also called hypertension, is dangerous because it makes the heart work harder to pump blood out to the body and contributes to hardening of the arteries, or atherosclerosis, to stroke, kidney disease, and to heart failure.

If the brain is not getting the right amount of blood flow due to a blockage or a leak, actions such as speech can be affected. High blood pressure, heart attacks, exhaustion, concussions, and other brain injuries can all affect the brain.

High blood pressure can cause hardening and thickening of the arteries (atherosclerosis), which can lead to a heart attack, stroke or other complications. Aneurysm. Increased blood pressure can cause your blood vessels to weaken and bulge, forming an aneurysm. If an aneurysm ruptures, it can be life-threatening.

If your blood vessels can't move blood through your body effectively, your heart and other important organs such as the eyes, brain, and kidneys may not get the oxygen and nutrients they need. High blood pressure raises your risk of heart, disease, heart attack, heart failure, stroke, and kidney disease.

High blood pressure can impair the function of the kidneys, leading to fluid retention and swelling of the legs, and even kidney failure. High blood pressure can affect the eyes, causing vision loss. High blood pressure can seriously affect the circulation causing pain in the legs with walking, cold feet, and stroke.

Along with causing heart and kidney problems, untreated high blood pressure can also affect your eyesight and lead to eye disease. Hypertension can cause damage to the blood vessels in the retina, the area at the back of the eye where images focus.

High blood pressure and stroke High blood pressure (hypertension) is the most significant risk factor for stroke.

Damage to your brain But high blood pressure can cause several problems, including: Transient ischemic attack (TIA). Sometimes called a ministroke, a TIA is a brief, temporary disruption of blood supply to your brain. Hardened arteries or blood clots caused by high blood pressure can cause TIA .

High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause: Chest pain, also called angina.

High blood pressure can also make a stroke due to a bleed (haemorrhagic stroke) more likely. One way this can happen is if you have an aneurysm (weakened blood vessel) in your brain. If this is damaged over time by high blood pressure, it can leak or burst, causing a bleed in the brain.
