Stroke

Stroke

The sudden death of brain cells due to lack of oxygen, caused by blockage of blood flow or rupture of an artery to the brain. Sudden loss of speech, weakness, or paralysis of one side of the body can be symptoms. ... Abbreviated CVA. Also known as cerebrovascular accident


OVERVIEW

Causes and types of strokes A stroke caused by a blocked artery is called an ischemic stroke. A stroke caused by a burst or leaking blood vessel is known as a hemorrhagic stroke. Another type of stroke is a transient ischemic attack (TIA), or mini-stroke. Ischemic stroke According to the CDC, most strokes are ischemic strokes. In this type of stroke, the arteries supplying blood to the brain narrow or get blocked. These blockages are often caused by blood clots or blood flow that’s severely reduced. The two most common types of ischemic strokes are thrombotic and embolic. A thrombotic stroke happens when a blood clot forms in one of the arteries supplying blood to the brain. An embolic stroke is when a blood clot or other debris forms in another part of the body — often the heart — and moves through the blood and gets stuck in brain arteries, where it causes a blood clot. Hemorrhagic stroke A hemorrhagic stroke happens when an artery in the brain suddenly breaks open or leaks blood. That leaking blood creates excess pressure in the skull and swells the brain, damaging brain cells and tissues. This stroke is often caused by high blood pressure and aneurysms. The two types of hemorrhagic strokes are subarachnoid and intracerebral. Intracerebral, the most common type of hemorrhagic stroke, happens when the tissues surrounding the brain fill with blood after an artery bursts. Less common is the subarachnoid hemorrhage, which is bleeding in the area between the brain and tissues that cover it. Transient ischemic attack (TIA) A transient ischemic attack, often called a TIA or a mini-stroke, is when blood flow to the brain is blocked for less than five minutes. Symptoms may be temporary and disappear after a few minutes. A TIA is often caused by a blood clot and is a warning of a future stroke. Don’t ignore a TIA. Seek the same treatment you would for a major stroke About Kidney Stones Kidney stones are hard pebbles that form inside your kidneys. Your kidneys are bean-shaped organs that filter the waste chemicals out of your blood and produce urine. Urine travels through your urinary tract to leave your body. The urine goes out of your kidneys, through your ureters (the tubes that connect the kidneys to the bladder; pronounced YUR-et-ers), and into your bladder. The bladder stores urine until it leaves your body when you urinate. Kidney stones form when tiny mineral crystals in your urine stick together.  Kidney stones can range in size and shape. They can be as small as a grain of sand or as large as a golf ball, although stones that big are rare. If a kidney stone is small enough, it can move or "pass" through your urinary tract and out of your body on its own. If the stone is too large, however, it could get stuck in your kidney or ureter. What is psoriasis? Psoriasis is a chronic skin disorder that produces thick, pink to red, itchy areas of skin covered with white or silvery scales. The rash usually occurs on the scalp, elbows, knees, lower back and genitals, but it can appear anywhere. It can also affect the fingernails. Psoriasis usually begins in early adulthood but it can start later in life. The rash can heal and come back throughout a person’s life. Psoriasis is not contagious and does not spread from person to person. In most people, the rash is limited to a few patches of skin. In severe cases, it can cover large areas of the body. How does the rash start? Psoriasis starts as small red bumps that grow in size, on top of which scale forms. These surface scales shed easily, but scales below them stick together. When scratched, the lower scales may tear away from the skin, causing pinpoint bleeding. As the rash grows larger, “plaque” lesions can form. .

About

It occurs when blood flow to an area of brain is cut off. When this happens, brain cells are deprived of oxygen and begin to die.
When brain cells die during a stroke, abilities controlled by that area of the brain such as memory and muscle control are lost.
stroke include trouble walking

Symtoms

Symptoms of stroke include trouble walking, speaking and understanding, as well as paralysis or numbness of the face, arm or leg. difficulty walking, paralysis with weak muscles, problems with coordination, stiff muscles, overactive reflexes, or paralysis of one side of the body

Causes

A stroke occurs when the blood supply to your brain is interrupted or reduced. This deprives your brain of oxygen and nutrients, which can cause your brain cells to die. A stroke may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (haemorrhagic stroke)

Treatments

If you are having a stroke it is important to get immediate medical attention—Call 9-1-1. The sooner you get treatment the better. Immediate treatment may help minimize the long-term effects of stroke and improve recovery outcomes
focus on limiting complications.
