Reduce Your Chances Of Having A Stroke

In spite of the fact that the numbness and weakness and were no longer there, Anna changed her busy schedule and went to the doctor instead.

In the doctor’s office, she thought she was a little silly for her panic. But the doctor took her temporary symptoms gravely. Anna's explanation of her symptoms indicate that she had a transient ischemic attack (TIA).

A transient ischemic attack is a intermittent or temporary neurological change, like a loss of coordination or weakness, that go on for five to thirty minutes and produces no permanent effects. But a transient ischemic attack is very significant. It can signal a warning and an opportunity – a warning of an upcoming stroke and a chance to stop from happening.

Knowing the signs of a possible stroke was beneficial for Anna.

Your life can change overnight with the instant devastation of a stroke. Rather than relishing your retirement plans, you confront the possibility of disability and dependence. Even worse, a stroke can devastate the family members struggling to accept death.

Changing and recognizing specific lifestyle habits can decrease a person’s chances of having a stroke. Medicines like aspirin and a surgical method called carotid endarterectomy may stop a serious stroke if you are at high risk.

If you already have experienced stroke, advance treatment with progressive therapies can lessen brain damage and future disability. Seventy percent of people who suffered from a stroke remain independent and another ten percent fully recover.

A "Brain Attack"

The human brain consists one hundred billion nerve cells and trillions of nerve connections. It is only two percent of your body weight but the brain uses seventy percent of the oxygen of the body and other nutrients. It needs a stable blood flow to keep it working correctly because the brain does not have the ability to store these nutrients like muscles do.

A stroke happens when this supply of blood is changed and the tissue of the brain is deprived of blood. Brain cells starts to die within just 4 minutes of being deprived of important nutrients.

Two main types of stroke:

Ischemic

An estimate of eighty percent of strokes are triggered by atherosclerosis, which is the buildup of fatty deposits called plaque that consists of cholesterol. The interior of the artery is roughened due to the development of plaque. The uneven surface can produce a turbulent flow of blood around the plaque buildup which is like a large rock in a rushing river and then triggers growth of a clot.

Majority of ischemic strokes are triggered by stationary (thrombotic) blood clots that grow in the arteries going from the heart to the brain – usually the carotid arteries in the neck.

A different but less frequent kind of ischemic stroke happens when a small part of clotted blood splits away from the walls of the artery and is carried through larger arteries then into smaller vessels in the brain. A clot that may have grown in the heart’s chamber can also split away. A stroke happens whenever the moving (embolic) clot gets stuck in a small artery and hinders the flow of blood to a part of the brain. An ischemic stroke normally impacts the cerebrum, the part of the brain that controls your senses, movement, and language.

Temporary and, normally, short symptoms originating from the disruption in the supply of blood indicates a TIA. Throughout a TIA, the body may supply enzymes that dissipate the clot rapidly and restore blood flow.

Hemorrhagic

Hemorrhagic stroke happens when a blood vessel in your brain ruptures or leaks. Damage is caused when the blood from the hemorrhage overflows into the brain tissue in the surrounding area. Also damaged are brain cells beyond the rupture or leak because of depravity of blood.

An aneurysm is one cause of a hemorrhagic stroke. Because of advancing age, this “ballooning” develops from a weak area in a wall of the blood vessel. Some aneurysms may also grow as a result of a genetic predisposition.

The vessel wall becomes thin and stretched as an aneurysm develops.

An aneurysm that is probably going to burst, is the one that develops to at least three-eighths of an inch in diameter.

Usually the catalyst of a hemorrhagic stroke is high blood pressure or hypertension. The strong force pushed by uncontrolled high blood pressure can damage walls of the blood vessel. Because of this, hemorrhage in the small blood vessels in the brain occurs. Whether or not a person has an aneurysm, high blood pressure escalates the hazard of a hemorrhagic stroke.

The rupture of an arteriovenous malformation is an uncommon originator of hemorrhage. This congenitally malformed network of thin-walled blood vessels can rapture and permit blood to overflow into sugar may decrease the danger of brain damage if you experience a stroke.

Undesirable blood cholesterol levels

Enhancing the hazard of atherosclerosis is high blood levels of low-density lipoprotein (LDL) cholesterol. While, high levels of high-density lipoprotein (HDL) cholesterol are defensive because they may stop growth of plaque.

Consuming a low-cholesterol and low-fat diet and regular exercise can decrease cholesterol level of the blood by as much as fifteen percent. Your doctor may recommend a drug to lower cholesterol, if your blood cholesterol levels do not enhance with lifestyle modifications alone.

Evaluating Early Warning Signs

Acknowledging the risk factors and healthy living are the best things you can do to avoid a stroke. Regular medical checkups must go together with a healthful lifestyle.

A physical examination is an opportunity for your doctor to evaluate your blood pressure and observe the heart for signals of valve or rhythm issues. Utilizing a stethoscope to listen to the carotid arteries, a doctor can discover a noise, called a bruit, created by unstable flow of blood through a decreased artery.

Whenever your doctor discovers a bruit, he or she can select from several specific tests to discern whether the artery is critically narrowed. A Doppler ultrasound scan can locate and establish the seriousness of the blockage through color imaging. The strength of the color shows the increase in rate of blood flow through the diminished area. For less serious narrowing, which is less than seventy percent obstruction; your doctor may give aspirin to thin the blood and help stop blood clots.

A drug called ticlopidine, may give moderately more defense than aspirin. It is an alternative for others who cannot take aspirin or who have had strokes or TIAs despite taking aspirin. But this medicine is costly and majority of the people who administer ticlopidine experience side effects like rash, nausea, and diarrhea.

Doctors may recommend carotid endarterectomy, if you have a severely narrowed (seventy percent or above) carotid artery. This preemptive surgery removes carotid arteries of plaque buildup before a stroke can happen.

If you have symptoms of stroke before and a critically diminished carotid artery, then carotid endarterectomy will decrease your risk of stroke. The advantages for persons with seventy percent below blockage or no stroke symptoms are less clear.

Know the Warning Signs

Contact your doctor immediately if you observe one or more of these signs. They can be warning signals for a possible stroke or transient ischemic attack:

  • Unexpected, acute headache with no obvious cause.
  • Speech deficiency, or difficulty talking or understanding speech.
  • Unsteadiness, dizziness with no apparent cause, or a sudden fall, usually if occurring together with the other symptoms.
  • Unexpected loss of vision, dimness or blurring, especially in one eye.
  • Unexpected numbness or weakness in your face, leg or arm on one side of your body.

Diagnosis Is Critical to Care

Treatment of a stroke is based on the location of where the stroke happened in the brain and whether it is hemorrhagic or ischemic. For instance, treating an ischemic stroke will require medicine to stop clotting of the blood. Whereas, administering an anticoagulant to treat a hemorrhagic stroke will lead to more damage and bleeding.

Your doctor may employ a magnetic resonance imaging (MRI) scan to diagnose a possible stroke. A magnetic resonance imaging scan is most sensitive for discovering a part of brain tissue destroyed by an ischemic stroke. For discovering a location in your brain damaged by hemorrhage, Computed tomography (CT) imaging is most useful.

Angiography requires injecting dye using a catheter inserted into a blood vessel suspected of being congested. X-rays results of these blood vessels display diminished blood flow or blockage. Angiography has the ability to discover an arteriovenous malformation or aneurysm.

A non-invasive way of uncovering blocked blood vessels is magnetic resonance angiography. Even if it has advantages against invasive angiography, the technology is costly and needs you to lie still enclosed in the MRI scanner, for up to 60 minutes.

What You Can Do to Minimize Your Risk

The recommended way to protect yourself against stroke is by not smoking. Exercise and a healthy diet can also decrease your risk:

  • Minimize fat and cholesterol - A diet abundant in fat and cholesterol, specifically saturated fat, may develop plaque buildup by adding the quantity of fat and cholesterol in your blood. Minimize the overall amount of poultry, fish or meat you consume to 5 to 7 ounces per day. Consume only lean portions of red meat. Select dairy foods created with low-fat or skim milk. Only eat four eggs per week. Stay away from lard and solid shortenings. Cook with monounsaturated oils (peanut, canola, or olive) or polyunsaturated oils (sunflower, corn, or soybean).
  • Consume a lot of vegetables and fruits. Organic produce have nutrients such as antioxidants, potassium, and folate that may fight against stroke.
  • Moderate alcohol consumption. More than two alcoholic drinks daily can escalate the blood pressure. If you consume alcohol, it is recommended you minimize daily dosage to no more than 24 ounces of beer, 8 ounces of wine, or three ounces of 80-proof liquor.
  • Minimize sodium intake. Whenever a person has high blood pressure, staying away from salty foods and not adding salt to meals could help decrease the blood pressure by 5 mm Hg. Refraining from salt may not stop hypertension. Excessive amount of sodium may increase blood pressure for people who are sensitive to it.
  • Regular Exercise. If you have hypertension, regular exercise is one of the few ways you can decrease your pressure without medicine. Three to four times of regular exercise weekly for twenty to fifty minutes may also directly decrease stroke hazard, although the exact mechanism is not known.
  • Keep a healthy weight. You are more likely to have diabetes, hypertension, and cardiovascular disease if you are obese. Getting rid of as little as ten pounds with exercise and diet could help decrease the danger of stroke by enhancing cholesterol to healthy levels and dropping your blood pressure.

Early Treatment Enhances Your Opportunity for a Complete Recovery

Injury from a “brain attack” progresses over time similar with a heart attack. Limiting the congestion in blood flow minimizes the permanent injury that happens as cells in the brain start dying. Receiving medical assistance immediately will mean the difference between life and death.

Treatment for both hemorrhagic and ischemic strokes, first requires diligent control of blood pressure. Blood pressure must be dropped slowly with medicines if it soars too high and becomes life-threatening. An unexpected slump in blood pressure causes the decrease in the blood supply to the affected area by the stroke.

Ischemic stroke treatment is targeted at enhancing flow of the blood:

Stopping recurrent clots. A platelet-inhibiting medicine like ticlopidine or aspirin decreases the tendency for blood to clot by stopping blood platelets from sticking together. Another drug that helps stop reformation of blood clots is Warfarin.

Regarding hemorrhagic strokes, the aim is to treat the origin of the hemorrhage and give protection from further brain damage by:

Lowering the pressure on your brain. Hemorrhage induces the blood to gather in your brain. Since the human brain is situated inside the skull, pooled blood or hematoma every so often can severely escalate pressure on the brain and injure soft tissue. Additional pressure can also hinder blood flow to the uninjured part of the brain.

Treatment is complicated. But still, a portion of therapy usually requires minimizing fluids and administering diuretic drugs to decrease temporary enlargement of brain tissue. To remove gathered blood clots from inside the location of damaged brain tissue, surgery is oftentimes required.

An aneurysm repair. When an aneurysm is discovered by an imaging scan, the surgeon could secure the aneurysm at its foundation and then extract it.

A different method uses a catheter, consisting of a metal coil, which is then inserted inside a blood vessel in the neck going to the location of the aneurysm. The coil forces the aneurysm to clot and closes itself off. In due course, the clot may turn into a benign scar tissue.

Treatment in the Future Hopes to Stop Damage in the Brain

A couple of hours following a stroke, brain cells in the location near the dead tissue may stay alive. To maintain undamaged tissues of the brain, researchers are experimenting medicines that may dissipate clots throughout the course of the initial 3 to 6 hours of a stroke. “Clot-busters” like streptokinase, prourokinase, tissue plasminogen activator (tPA), and urokinase may be used as a treatment for some kinds of ischemic strokes in the coming years.

Research indicates that not all destruction created by some strokes is the cause of the depravation of oxygen and blood. The damage could be caused by chemical reactions happening inside the impaired brain tissue.

While a stroke is occurring, brain cells (neurons) generate a surplus of neurotransmitters, the molecules utilized for communication with one brain cell to another. Experts are researching for medicines that defend brain cells from this short-lived but destructive “neurotransmitter overload.”

Disability Depends on Location of Damage

The human brain is separated into two halves (hemispheres). Normally, damage to the brain is restricted to a small region in one hemisphere. Even though both sides of the brain have the same functions, each hemisphere manages the sensation and movement on the opposite part of the body. And each individual hemisphere is tasked in different special functions of the brain.

For instance, if a stroke occurs in the brain's right hemisphere this may result in paralysis and vision/ sensation deficiency only on the left portion of the body. There may also be trouble in determining size, distance, and rate of movement (spatial relationships). Additionally, the person’s behavior could be impulsive and quick.

If the injury is in the left brain, there could be equivalent paralysis and loss of sensation and vision on the right half. Instead of having trouble with spatial relationships, there could be struggling when speaking or understanding speech. And there may be slow and cautious behavior.

Recovery Means Making the Most of Your Capabilities

Unconscious to you, the body starts to recover soon following a stroke. For the first 3 weeks, some individuals show significant improvement in their capabilities to see, talk, and move. While other people display slow recovery.

Most cases, significant progress in moving happens during the first 1 to 6 months. Progress in speech, steadiness and the capability you need to handle yourself may be steady for up to two years.

Approximately half of stroke survivors have ongoing difficulty with Judgment, coordination, behavior, or communication, which impact their social and work relationships. However, only up to ten percent need long-term therapy.

Programs for rehabilitation strengthen the self-healing procedure. The aim of therapy is to assist the patient make the most of their mental and physical abilities while adjusting to their weaknesses. Rigorous rehabilitation, which occurs five to six days per week, started during hospitalization, is most helpful for long-term healing.

Rehabilitation programs in hospitals usually necessitate a group approach with occupational, speech, and physical therapists. Physical therapy assists in enhancing your mobility to aid you to learn how to stand, lie, walk, and sit again.

Occupational therapy can help you grow the interpersonal, mental, and physical skills required to begin day to day activities. These skills could be as simple as learning to change clothes or as complicated as utilizing a computer with an altered control switch. If you cannot manage the muscles and nerves in your tongue, throat, and mouth, a speech pathologist or occupational therapist can aid you to relearn to swallow in a safe way.

In case you have lost your capability to talk or comprehend language (aphasia), a speech pathologist can employ teaching tools, like computers and spelling boards, to assist you in learning alternative methods to communicate.

For many recovering stroke survivors and for their families, handling social and psychological consequences is more exhausting than adjusting to mental and physical limitations:

  • Depression. Sixty percent of people who suffered from stroke exhibit symptoms of depression. Around one-third feel anxious or angry. Others experience periodic bouts of crying or sadness.
  • Social isolation. This emotion originates from a physical disability but could persist even after physical restraints are overcome. Anger or depression could result to a feeling of isolation. Recovery could also turn to a grieving phase that involves embracing your loss, adjusting to restrictions within the surroundings and spending energy towards new pursuits and social positions.

Additionally, to the encouragement of your family and faith, community services like stroke support circles, senior citizen centers and public transportations accessible to persons with disabilities can assist in decreasing emotions of isolation.

Recovery is a personal obstacle. Only if you are truly committed to the activities of your day to day life and appreciate change as an invigorating trial, will you adjust more quickly and efficiently.

Establish Prevention as a Way of Life

Anna was fortunate that her transient ischemic attack signaled her to undergo preventive care that could aid her stop a possible stroke.

Unfortunately, for a lot of people, a stroke gives no deterrent. Hazardous factors like hypertension, high blood cholesterol, and diabetes progress silently and slowly for years. Decreasing the risk rakes understanding of these factors, supported by the dedication to a life of healthy living.
