In ischemic stroke, parts of your brain are deprived of nutrients and oxygen when blood vessels are blocked. These damages the brain cells begin to die the same. Ischemic stroke can occur in two ways.

Arterial thrombosis: It occurs when a blood clot forms (thrombus) in a blood vessel that supplies blood to your brain and blocks such supply.

Cerebral embolism: It occurs when a blood clot that formed somewhere else in your body (embolus), travels to your brain and blocks blood supply.

Your brain controls everything the body does, including movement, speech, vision and emotion. Damage to the brain can affect any of these functions. After having an ischemic stroke, approximately one in three people recovered all or most of these functions.

Ischemic strokes are more common in people over 65 years of age but can occur at any age.

SYMPTOMS OF ISCHEMIC STROKE

The ischemic stroke symptoms occur suddenly, within seconds or minutes. Less frequently, symptoms may occur and go and worsen in the course of several hours to a day or two.

A good way to recognize if someone has had a stroke is by test called FAST, for its acronym in English, face, arms and speech, which will determine if it’s time to call 999. This requires checking for any of the three main symptoms of a stroke, facial weakness, arm weakness and speech problems.

The exact symptoms of ischemic stroke depend on where the brain to which interrupted blood supply. For example, if you block a blood vessel that carries blood from the front of your neck to your brain, you may have:

• Blindness in one eye

• Paralysis or weakness in one arm or leg on one side of body

• Trouble understanding people or to find the words to speak

Or, if it blocks a blood vessel that carries blood from the back of your neck to your brain, you may have:

• Double vision

• Weakness on both sides of your body

• Dizziness and vertigo

If you find that anyone has any of these symptoms, you should immediately call emergency for stroke treatment.

COMPLICATIONS OF ISCHEMIC STROKE

Some ischemic strokes can be quite mild and the effects are only temporary, while others may be more severe and lasting damage. The complications of ischemic stroke may include:

• Weakness or paralysis, usually on one side of the body

• Lack of awareness of one side of your body (usually the left side)

• Loss of sensation on one side of the body

• Trouble swallowing

• Extreme tiredness and sleeping problems

• Trouble speaking, reading and writing

• Problems with vision, such as double vision or partial blindness

• Difficulties with memory and concentration

• Difficulty controlling their bladder and bowel movements (incontinence), or constipation

• Behavioral changes

The problems such as anxiety, depression and seizures may often improve as he recovers.

If you can not move due to a stroke, may be at risk for:

• Bedsores (pressure ulcers)

• Deep vein thrombosis (DVT)

• Pneumonia

• Contractures (altered position of the hands, feet, arms or legs due to muscle stiffness)

CAUSES OF ISCHEMIC STROKE

Ischemic stroke occur when a blood clot or fat mass obstructing the blood supply to the brain. The obstruction can develop in one of the brain’s blood vessels (arterial thrombosis) or come from somewhere else in your body (piston stroke).

You run the risk of developing a blood clot if your blood vessels are narrowed and coated with fatty deposits, a process known as atherosclerosis. This often happens as people age. You can also take NeuroAiD. You can also develop atherosclerosis if you:

• Smoking

• has an uncontrolled hypertension

• have high cholesterol

Or obesity • overweight

• have diabetes

• have a family history of stroke or heart disease

You are also at risk of having an ischemic stroke if you have a type of abnormal heart rhythm (arrhythmia) called atrial fibrillation. In atrial fibrillation, the heart does not pump blood properly and this can cause the formation of a blood clot in his heart. The clot can then travel to the brain and cause a stroke. Excessive drinking regularly can put you at risk of developing an abnormal heart rhythm and blood pressure increase.
