How your neurology is challanged by High Blood Pressure.
If your blood pressure is normal, you can work with your health care team to keep it that way. If your blood pressure is too high, you need treatment to prevent damage to your body’s organs. High blood pressure is dangerous because it makes the heart work too hard and contributes to atherosclerosis (hardening of the arteries).
High blood pressure cause arteries inside the brain lose elasticity or become twisted and blood doesn't flow through them as well.
As a result, the neurology can change and the neurons that do your thinking and operate your moving parts as well, don't get the oxygen or glucose they need to function properly. So the arteries in the brain become clogged or twisted. Picture a damaged artery as a damaged garden hose, twisted and partially blocked; thus preventing water from reaching its target. The same thing can happen in the brain where the arteries lose their efficiency.
Atherosclerosis is often called the "silent killer" because it can damage your heart, kidney, and brain, even though you feel no symptoms. Blood pressure is the force exerted by circulating blood on the walls of blood vessels, and constitutes one of the principal vital signs.

Blood pressure is a measure of how hard the blood pushes against the walls of your arteries as it moves through your body.
Doctors do not know what causes high blood pressure in 90 to 95 percent of people who have it. In about 10 percent of patients, the disease can be traced to specific causes: heredity, kidney abnormalities, adrenal gland tumors, diabetes, chronic kidney disease, hormone abnormalities, use of birth control pills, pregnancy or a congenital narrowing of the aorta.
Other possible causes of higher blood pressure are weight gain and decreased physical activity in winter. The nicotine in cigarettes and other tobacco products causes your blood vessels to constrict and your heart to beat faster, which temporarily raises your blood pressure. In some people, alcohol causes blood pressure to rise quite a lot.
The key for any high blood pressure treatment is to bring the condition under proper control.
Treatment depends on how high your blood pressure is, whether you have other health problems such as diabetes, and whether any organs have already been damaged.
Treatment begins with changes you can make to your lifestyle to help lower your blood pressure and reduce your risk of heart disease. You want to achieve your treatment goal, but sometimes it seems your blood pressure just doesn't want to budge.
You and your doctor can carefully review your treatment and lifestyle to see what's going on. For hypertension that isn't controlled by diet and exercise, new treatment guidelines for hypertension recommend that most patients be started on a thiazide-type diuretic, unless there is a compelling need for a different class of medications.
The brain is arguably the main organ in our body. Arteries carry blood away from the heart, toward organs such as the brain. If those arteries become damaged or clogged, the brain is starved of the oxygen and nutrient-rich blood that fuels nerve cells (neurons) and carries away waste. The result: brain function deteriorates and the risk of dementia increases and changes in neurology and other neurological functions detieriate.
When arteries inside the brain lose elasticity or become twisted, blood doesn't flow through them as well. As a result, the neurons that do your thinking don't get the oxygen or glucose they need to function properly.
Every time your heart beats, blood pumps through the arteries, creating pressure against their walls. Unfortunately, as we age, that pressure increases; as a result, the heart needs to work harder to pump blood to your organs.
With each pulse of blood, your arteries have to expand like a python enveloping its prey. The smaller the artery is, the bigger the size of the pulse it takes. Over time, this process taxes the arteries, changing them in ways that decrease blood flow to the brain.
High blood pressure (called hypertension) occurs when too much stress is placed on the walls of the arteries. Sometimes called the silent killer, hypertension can occur without symptoms or major warning signs.
But beneath the surface, the force required to pump blood throughout the body can wreak havoc on blood vessels.
The Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure recommends screening adults for high blood pressure every two years if their blood pressure is normally less than 120 mmHg (systolic)/80 mmHg (diastolic).
Hovering above the normal range? Get checked more often. The figures below are a guide and are not meant to contain medical advice.
* A normal systolic blood pressure is below 120.
* A systolic blood pressure of 120 to 139 indicates prehypertension (borderline high blood pressure).
* A systolic blood pressure number of 140 or higher is considered to be hypertension.
* A normal diastolic blood pressure number is less than 80.
* A diastolic blood pressure between 80 and 89 indicates prehypertension.
* A diastolic blood pressure number of 90 or higher is considered to be hypertension.
