What High Blood Pressure Does to the Brain?

What High Blood Pressure Does to the Brain?
Around two-thirds of the global population suffers from high blood pressure. World Health Organization (WHO) reckons hypertension as one of the major causes of premature deaths. It is crucial to understand the severity of high blood pressure and what damage it can cause to your brain.

What Is High Blood Pressure?

What Is High Blood PressureAs blood pumps through the arteries, it exerts some force on the walls. When the amount of force increases, the condition is called high blood pressure.

High blood pressure is measured in two numbers. Systolic, i.e., the first number represents the force exerted when the heartbeats. The diastolic or the second number measures the force in between beats.

Contrary to popular belief, high blood pressure has adverse effects on all parts of our body, including the brain, kidney, arteries, heart, eyes, bones, legs, hips, stomach, and genitals.

What Are The High Blood Pressure Effects On The Brain?

The core cause of high blood pressure effects on the brain or any other organ is the blood supply. When there are changes in the natural flow of nourishing blood supply to the brain, it ceases to function, resulting in damages.

Here are the high blood pressure effects on the brain:

  • Stroke

    StrokeStroke is a condition when blood supply to your brain is stopped or reduced. It can occur because of the clogging of arteries in the brain or the rupture of an artery. When the brain is deprived of oxygen through the blood, it tends to dysfunction, resulting in brain functions such as vision, movement, speech etc. High blood pressure is a significant contributor to the development of stroke, especially in elderly people.

    Loss of memory, paralysis, and even death can be the resultants of a severe stroke. According to WHO, around 80 million people in the world are stroke patients.

  • Transient Ischemic Attack

    Transient Ischemic AttackDoctors refer to TIA (Transient ischemic attack) as a mini-stroke. In this condition, the blood flow disrupts and restores within minutes or hours, unlike a stroke, where the disease may last a day or a lifetime.

    The symptoms are similar to the stroke, wherein you may experience numbness, slurred speech, blurred eyesight, etc. If you contract a TIA, a full-blown stroke may also appear. Hence, one must visit the doctor and strictly follow the guidelines.

  • Vascular Dementia

    Vascular DementiaDementia adversely affects your memory and judgmental capacities. The person may not be able to make minute decisions, hindering his daily activities. High blood pressure affects brain functioning by depriving the nutrients and oxygen. It hampers the cognitive ability of the person, impairing his daily activities.

    Dementia starts gradually through forgetfulness. We tend to ignore the symptoms until the patient begins to forget his close family members. However, in most cases, vascular dementia is the after-effect of a severe stroke or transient ischemic attack.

  • Alzheimer’s

    Alzheimer'sAlzheimer’s is another kind of dementia. It is a terminal illness and is yet to have a cure. The risk factors are a family history of the disease and lifestyle. Apart from that, the exact reason for Alzheimer’s is still unknown. Though it is not caused directly by high blood pressure on the brain, controlling blood pressure helps block further progression of the disease.


High blood pressure effects on the brain do not stop here. Depression, anxiety, mild cognitive impairment are all the underlying conditions that eventually take the patient to fatalities. Hence, it is advised to consult the doctor and regularly continue the medications.
