The study, published in Stroke, examined the relationship between stress and the risk of subarachnoid hemorrhage, which occurs when the rupture of a vessel causes bleeding into the space surrounding the brain. Up to half of cases are fatal. It is common that people attributed to sudden stress health problems, such as a stroke, said Dr. Craig S. Anderson, George Institute for International Health and the University of Sydney, Australia.
In the case of a subarachnoid hemorrhage, told Reuters Health, it is possible that a sudden increase in pressure produces a rupture in an aneurysm, a weakened area in the wall of an artery. Sometimes this bleeding occurs by a sudden exertion, such as during exercise or sex, said Anderson. But whether stressful life events increase the risk of suffering a stroke.
Anderson’s team interviewed 388 survivors of subarachnoid hemorrhage who had undergone stressful experiences between one month and one year before the stroke. The survey focused on 12 types of situations, such as the death of a relative or friend, loss of job or have suffered a crime. The team then compared the responses with those of a control group of 473 people the same age who had never suffered a subarachnoid hemorrhage. And most of the situations was not related to the risk of bleeding.
But analyzing the experiences of the previous month, two types of stressors, financial or legal problems and “other significant events” – yes were associated with increased risk. 10 percent of the survivors said they had a financial or legal problem the month before the bleeding, as opposed to 4 percent in the control group.
But in considering factors such as hypertension, smoking and alcohol consumption, the relationship between these stressors and the bleeding was only “marginally” significant. There was also an association between the occurrence of subarachnoid hemorrhage have been the victim of a crime the previous year (4 percent of survivors and 1 percent of the control group).
On the other hand, the risk of bleeding decreased in those who had had a family member or friend very ill or had an accident the previous year.
That, according to the researchers, is that the study looked at 12 types of experiences, the few that were weakly associated with the risk of bleeding as they were by chance alone.
Stress, Anderson said, it is very difficult to measure for researchers. The study used an approach of analyzing the rates of the major events that often cause psychological stress. Are unknown real individual responses to these situations. Still, “we can say that ‘stressful experiences’ are not an important risk factor for subarachnoid hemorrhage.”
To prevent it, recommended that people focus on preventing or treating known risk factors of cerebral hemorrhage, which include smoking and hypertension.
Although studies have associated the use of folic acid supplements with a lower rate of stroke (CVA), a review of trials showed that the vitamin does not serve to prevent the disease. “We have no evidence to ensure that acid strengthening Folic reduces stroke, “he told Reuters Health Dr. Jeffrey Saver.
Saver’s team of UCLA Stroke Center, Los Angeles, identified 13 well-designed clinical trials on the relationship between folic acid and stroke. Participants were conditions like kidney failure and cardiovascular disease, including stroke. In the study, there were 784 attacks in 20,415 participants who had taken folic acid, as opposed to 791 in 18,590 people who had not taken the supplements.
The review, published in the journal Stroke from the American Heart Association, responds if the use of folic acid supplementation induces a significant reduction in stroke. And for Saver, “the answer is ‘no’.” Still, the team suggested that more research is needed on folic acid and stroke, especially in men and in those with the initial state of heart disease.
Data from both groups suggested that there would be an effect, although the team could not determine whether or not it should be random. This potential benefit was observed in clinical trials in countries where foods are not fortified with folic acid. In the U.S., this benefit would be achieved through food fortification, according Saver.
From 1998 to prevent the birth defect spina bifida, the Food and Drug Administration called for adding folic acid to all enriched grain foods.
People who eat plenty of fruits, vegetables and dairy products rich in potassium would be less likely to have a stroke (CVA), suggests a review of 10 international studies published in the journal Stroke.
The authors found that the risk of stroke decreased with increasing the amount of potassium consumed by the participants: 1,000 mg per day over the possibility of having a stroke in the next five to 14 years declined by 11 percent. That, to the authors, would result in a slight individual benefit.
Furthermore, the results do not prove that potassium is responsible for the positive effect, although available evidence reinforces it could be, said lead author Susanna C. Larsson, Karolinska Institute, Sweden.
Potassium is an electrolyte that the body needs to maintain water balance and is involved in nerve and muscle control and regulate the pressure. Several studies have suggested that diets rich in potassium can keep the pressure stable, which protect them from stroke and cardiac infarction.
Of the nearly 270,000 adult participants included in the review, 8695 (one in 30) suffered a stroke. Reducing the risk of stroke seen with 1,000 mg each day more potassium was recorded after considering factors such as age, exercise and smoking.
Potassium was specifically associated with reduced risk of ischemic stroke (a clot that blocks a brain artery), which represents 80 percent of strokes. But did not influence the risk of hemorrhagic stroke (bleeding in the brain). If potassium only protects against ischemic stroke, researchers say it suggests that its effects would go beyond control the pressure.
The results are consistent with a recent study by the Centers for Disease Control and Prevention (CDC for its acronym in English), which was monitored for 15 years to more than 12,000 adults. Participants who ate large amounts of sodium, but little potassium, were more likely to die from any cause during the study.
That’s because potassium balances the effects of sodium to maintain low pressure and help the body eliminate liquid. So the combination of too much sodium and little potassium would be especially dangerous to health. But there are cases in which we must be very careful with potassium, as in people with kidney disease that alters the body’s ability to remove potassium, and users of certain anti hypertensive agents.
Too much potassium in the blood may cause hyperkalemia or hyperkalemia, a condition that causes cardiac arrhythmias risky.
People who have suffered a stroke can sometimes see the reading impaired. Calling this kind of alteration Acquired Dyslexia. This disorder can occur in conjunction with language disorders or in isolation. Different types of acquired reading disorders that are intimately related to the size of the lesion and the brain areas that it affects.
The left cerebral hemisphere (HI) is responsible, in most people’s language functions, but the right hemisphere (RH) also supports certain reading skills. This is why people with damage to the HI can recover some reading skills through the damaged hemisphere in collaboration with the HD.
The alteration of reading not only prevents the individual to enjoy recreational activities such as reading the newspaper, a book or watch a movie with subtitles, also interferes in other areas of their daily tasks like paying bills, follow written instructions or using the computer. Associated then a feeling of effort and frustration to any of these activities.
Some ideas to optimize the reading after a stroke:
* In some cases, silent reading is much easier than reading aloud, because it is affecting your ability to produce speech sounds. That’s why reading aloud words require an unnecessarily difficult process, because in any case the person can understand the contents of the text reading silently.
* Some people used very successfully called Audio Books. These books recorded on CD or DVD. They are available in a variety of subjects to continue to enjoy hobbies or favorite authors but the reading is severely affected.
* There are some foreign words or names that contain combinations of letters and / or unusual sounds in the Castilian and generate an extra difficulty when reading. To address these words is helpful to transcribe them as they should sound in Castilian. For example the word “jogging” transcribed “yogin.”
* It is useful to pay close attention to the photos related to newspaper articles or magazines. Often clarifies the topic of the article. Similarly, surf the web for pages that contain photos or videos along with text helps associate written words with their meanings.
* Many DVD movies have the option to put subtitles in the same language which is spoken for people with hearing loss. This option will reinforce the mechanics of reading without losing the subject of film dialogue.
It is also essential that a person who has suffered a stroke therapies make the damaged functions, the language and literacy are sensitive to rehabilitation and the sooner they are addressed, best results are obtained.
Granada neurologists find that thrombolysis provides an independent living provides 50% of patients after stroke
Neurologists of the Hospital Virgen de las Nieves of Granada have found that the treatment of ischemic stroke thrombolysis can be raised from 30 to 50 percent the number of patients who are able to lead an independent life after three months of suffering heart attack brain.
Stroke or stroke is the sudden cessation of the blood flow to the brain and in Spain is the leading cause of death among women and second in men, explained the Head of Service of Neurology Hospital of Granada, Angel Ortega.
He noted that 80 percent of strokes are ischemic, caused by blockage of an artery, while the remaining 20 percent are hemorrhagic-due to rupture of an artery, “and added that thrombolysis, consisting of the application of a drug intravenously, can only be applied in the former case, since it seeks to dissolve the clot that caused the infarct.
Process coordinator stroke at the Hospital Virgen de las Nieves, José Maestre, stressed that, at present, thrombolysis is the only specific treatment for ischemic stroke and noted that only can be applied in the cases that come within three hours following the onset of first symptoms, and in patients with certain levels of stress and blood sugar, among other parameters. Master explained that the treatment applied since February 2002, since when they reached the hospital Granada 2,500 cases of ischemic stroke, of which only could apply thrombolysis in just over 1 percent, a percentage that would have risen to 10 percent whether patients had reached on time. Therefore, said it is critical that citizens become aware of the importance of early detection three characteristic symptoms of stroke, either ischemic or hemorrhagic, which are the deviation of the mouth, loss of strength and sensitivity in the body and difficulty speaking and understanding. He noted that since that thrombolysis can be applied is essential to take time with patients, it is essential that nurses give priority to the care of these patients.
In this regard, claimed the implementation of the Plan Board (Acute Stroke Plan), to coordinate the performance of the system to a case of stroke, announced by the Ministry of Health for a year and a half and has only up unofficially in the Virgen del Rocio Hospital in Seville, where he has been multiplied by three the number of patients arriving in time to be treated. Master said, according to statistics that handle a third of people who suffer an ischemic stroke die, another third have serious consequences and it exceeds 30 percent spontaneously, while the implementation of thrombolysis this percentage rises to 50 percent. He explained that since February 2002 have been treated with thrombolysis and 34 patients Granada, of which 11 disease went into complete “spontaneous” and 17 others through treatment, “which actually means that six people were cured. He stressed that although this number may seem “too small” treatment success would have a greater “impact” if you were holding more people in time.
Currently, thrombolysis is applied on an “interim” in about 40 hospitals in Spain as the European Medicines Agency has not yet finally authorized the use of the drug in which it is based.
A new Canadian study just an apparent paradox impact on health has been known for years: Why patients admitted on weekends are more likely to die than those who do on weekdays?
The latest research, published in the journal Neurology, has investigated over 20,000 cases of hospitalization for stroke or stroke, and identified the same pattern: those who went to the hospital on Saturday or Sunday had a 8.1% risk of dying, compared with 7% of the remaining affected after taking other risk factors such as age, severity of urgency and other conditions.
“We wanted to determine whether the severity of stroke on weekends compared to weekdays, could explain the lower survival rate,” says Dr. Moira K. Kapral, author of the study from the University of Toronto in Ontario (Canada). “Our results suggest that the severity of infarction is not necessarily the reason for this discrepancy.” Read the rest of this entry »
Promoted by the World Stroke Organization (WSO) has launched a campaign slogan that 1 in 6 for 2 years (2010-2012) aims to disseminate information to save lives and share knowledge about actions and behaviors life that may prevent a stroke. This is the main cause of disability worldwide. The campaign also highlights the critical importance of providing quality care and long term support after suffering it.
The motto under which celebrates this year is 1 in 6, then every six seconds someone dies of a stroke or brain attack, regardless of age or sex. In the 5th. Stroke World Congress, held on June 24, 2004 in Vancouver, Canada, was established on 29 October as World Day ictus.
We call for urgent action to this silent epidemic of stroke, through the campaign 1 in 6. This time, the campaign led by the World Organization for stroke, is proposed to reduce the burden of this epidemic by acting on six aspects:
1. Know your personal risk factors: hypertension, diabetes, high cholesterol.
2. Be physically active and exercise regularly.
3. Avoid obesity through a healthy diet that includes plenty of fruits, vegetables and low in fat.
4. Limit alcohol consumption.
5. Avoid cigarette smoking. If you smoke, get help to quit now.
6. Learn to recognize the warning symptoms of stroke and how to proceed if they occur. Read the rest of this entry »
Warning signs. If you have any of the following symptoms with a sudden onset:
- Loss of strength in the face, arm or leg on one side of the body.
- Disorders of sensation, feeling “tingling” of the face, arm or leg on one side of the body.
- Sudden loss of vision, partial or total, in one or both eyes.
- Slurred speech, difficulty in speaking, it costs us to articulate and be understood by those who hear us.
- Feelings of extreme dizziness, unsteadiness, imbalance or sudden unexplained falls, together with any of the symptoms described above.
- Headache of sudden onset, intensity unusual and unexplained.
You can have a stroke and its consequences can be death or disabling sequel do so dependent on another person or caregiver.
What should you do?
1. Tell a relative, friend or neighbor to join you
2. Rushed to the hospital or call the Integrated System of Emergency.
What Not To Do
- Wait until it passes
- Do not tell anyone not to bother
- Warn your family doctor to come to your house to visit when you can
Do not waste time, every minute counts
Statins (Lipitor, Pravachol, Zocor, Crestor, etc.) Should be initiated early after a first stroke (AC) or transient ischemic attack (TIA).
These drugs not only decrease the risk of a new cerebrovascular event, but also reduce the risk of coronary events, even in patients without history of cardiovascular disease.
This follows from the SPARCL study (Stroke Prevention by Aggressive Reduction in Cholesterol Levels) presented at the 15th European Stroke Conference in mid last year.
Statins have been used traditionally to normalize cholesterol levels in patients with dyslipidemia.
However, the evidence of this scientific work shows that the statin (Lipitor) has benefits beyond just reducing LDL “bad” or LDL, but even in patients with normal total cholesterol, this drug prevents the possibility of a new stroke or coronary event. Read the rest of this entry »
Atrial fibrillation (AF) is an arrhythmia that is associated with stroke (AC) by emboli from the heart.
This arrhythmia causes turbulence in the atrium or left atrium, which helps the formation of thrombi or clots that travel through the aorta to the brain, causing blockage of a cerebral artery and finally AC.
To prevent AC in patients with AF, can handle a blood thinner such as warfarin or acenocoumarol, or simply aspirin.
In under 75 years it is clear that thinner is better than aspirin in preventing AC in patients with AF. But over 75 years, the benefit is lower, increasing the risk of bleeding from anticoagulant, sometimes fatal.
The study BAFTA (Birmingham Atrial Fibrillation Treatment of the Aged) compared Warfarin versus aspirin in patients over 75 years with AF and showed that warfarin is superior to aspirin in the Stroke Prevention in Atrial Fibrillation, as long as they keep a good control of anticoagulation, which should be indicated by blood tests regularly calls the prescribing physician.
The results were published in the journal Lancet on August 11, 2007 and had previously been released in Glasgow, at the 16th European Stroke Conference in Glasgow, Scotland, where I was fortunate to attend.
