Improve stroke

No less than 130 000 accidents strokes occur each year. At the end of the first month, about 20% of patients die while 75% of survivors have permanent sequelae. It is the leading cause of disability acquired from adults, often aged in Western countries. With the increase in life expectancy, this disease will take in the next few years an unprecedented magnitude. To cope, a restructuring of its management is necessary.

The stroke is an abrupt shutdown of the blood flow to the brain. Cerebral vascular accidents (CVAS) are mostly due either to a clot in the artery (is the case three times out of four), hemorrhage, is kind of breach of the walls of the vessel. The ageing of the population suggests an increase in incidence and the burden of this disease for the company.

Reform the Organization of care
For several years, the experts point out the vital interest of the stroke as an extreme emergency, such as myocardial infarction. Only radiological tests to distinguish the type of strokes and thus to choose the appropriate treatment. The treatment of the stroke requires a multidisciplinary support.

First national plan to combat cardiovascular disease

First dated, this three-year plan is an unparalleled scale. With a budget of 30 million to€ uros, the Ministry of health proposes to reduce 20% of cardiovascular diseases over the next ten years.

Although his following a skiing accident, the Minister of health Bernard Kouchner has plans of public health at the speed of a sprinter. This time, the France is developing the first national program of cardiovascular risk reduction. And the Minister the announcement clearly: “if we should remember that a public health plan, this would be it!”.

First national plan to combat cardiovascular disease

Public health priority
Cardiovascular diseases are the leading cause of death in France with almost 180 000 deaths per year. No fewer than 120,000 people are treated each year for myocardial infarction and 130 000 for a stroke. And 20 million people are affected by these diseases prevention approaches. The origin of this carnage, the risk factors are identified: tobacco, physical inactivity and obesity, high blood pressure, diabetes mellitus, too high levels of lipids in the blood. The new national program proposes to consider prevention as a whole. Continue reading “First national plan to combat cardiovascular disease”

Stroke: inform for better care

Accident benefit stroke of enough attention? The challenge, however, is crucial: only the identification of the first symptoms and early consultation allow to limit the consequences. For the first time, a global survey attempts to assess the level of information to the public on this scourge.

Cerebral vascular accidents (CVAS) benefit or campaigns of information or other major diseases research fund. Yet is the second cause of death and the leading cause of disability in adults.

inform for better care

First global survey
What is the level of information to the general public on the cerebral vascular accidents (CVAS)? To find out, an investigation was launched September 27, 2004, on the Internet in Europe, the Canada and the United States. This first was implemented with the assistance of associations of fight against stroke in France, Germany, Italy, the United Kingdom, the United States and the Canada and is sponsored by AstraZeneca. It is available at the following Internet address: Everyone can respond, regardless of knowledge or personal experience of the disease. Continue reading “Stroke: inform for better care”

Strokes: the rehabilitation goes virtual

Nearly 130,000 people suffer each year from a stroke. Among them, half will have to deal with more or less severe disabilities, requiring a grueling rehabilitation. But virtual reality could soon help these patients to recover faster.

Strokes are the leading cause of disability in adults. After such an ordeal, a long and grueling rehabilitation is usually necessary. But tomorrow, the virtual reality will facilitate the recovery and home care.

the rehabilitation goes virtual

Virtual reality rehabilitation aid
Virtual rehabilitation system combines virtual reality – an interactive environment in three dimensions in which the patient can act – with traditional processing techniques. This method allows the therapists new tools for greater efficiency and motivation of patients, which sometimes tend to move away from the traditional exercises due to lack of interest.

“Virtual reality shows encouraging signs to promote a faster and more complete rehabilitation, but the cost of many of these prohibitive rest systems and disabled a generalization of this method in medical clinics and medical centres” said Grigore Burdea, Professor of computer science and co-inventor of a new low-cost. “While it is important to continue the technological research, is also important to find ways to make these treatment accessible to the greatest number of people in need”.

The future at your fingertips
Engineers from the University of New Jersey changed games consoles popular to help victims of a cerebral vascular accident patients to perform manual movements as part of their rehabilitation. The entire system is less than 600 dollars and could soon compete with ten times more costly systems.

The Rutger’s low-cost virtual rehabilitation system is based on the Microsoft’s Xbox console and game Essential reality P5 glove that senses the movements of the fingers and wrist to manipulate images on the screen. The engineers made minor changes thus creating two exercises to recover a manual dexterity after a stroke. In a Dexterity exercise, the patient must clean four vertical bars of ‘dirty pixels’ preventing from see the image that is behind. In a quick exercise, patients should keep a butterfly that flies in the screen.

The researchers acknowledge that the used glove has not or accuracy of gloves specially designed for rehabilitation, not the ability to accurately measure the movements or to provide a dynamic opposition. But this inexpensive system can seduce some clinics with limited means and could soon offer the possibility of a continuation of the training at home under the supervision of the doctor that can monitor progress via the internet.

Improve stroke

While traveling to Poitiers early October 2009, the Minister of health Roselyne Bachelot presented a new report on stroke. Beyond an alarmist report, several proposals are put forward to better prevent and support the third cause of death in France.

Roselyne Bachelot-Narquin, Minister of health and Sports, presented a report on the cerebral vascular accidents (CVAS) from the work of a Steering Committee installed late 2008 and coordinated by Dr. Elisabeth Fery-Lemonnier, General Counsel of the health facilities. This3 report gives the State of alarmist but advance sites also tracks to improve management and stroke prevention.

AVC: the third cause of mortality
Stroke is the leading cause of disability acquired adult3, the second cause of dementia (after Alzheimer’s disease) and the third cause of mortality in France.

Involving every year approximately 130 000 new patients in France, the risk of stroke is double every 10 years after age 55. For example, a quarter of stroke occur in less than 65 years (IE in the workforce), and more than 50% among people aged 75 and over. In the British registry of Oxfordshire, the stroke is more common than myocardial infarction (45% vs. 42% of vascular events). After a first stroke, the risk of recidivism is important, estimated between 30 and 43% in five years.

STROKE and cerebrovascular disease are one of the main causes of mortality in France, more in women than in humans. After age 65, the number of deaths from stroke in women is equal to that due to myocardial infarction in humans. Strokes are the second leading cause of mortality in the world, both in countries with high income in3 developing countries.

Despite this dramatic, the stroke is unknown, both the general public and health professionals.

Better to prevent stroke
According to the national Institute (Inpes) health education and prevention, stroke-related knowledge of the French are weak and disparate, both with regard to the symptoms (only 30% identify the sudden weakness of the hemicorpus as a sign of stroke) than to do (only 50% of the French would use the Centre 15).

What tests for what diagnosis?

Stroke is a medical emergency. Quickly, the doctor must be able to determine whether it is an interruption of blood flow or bleeding and if the affected brain tissue is recoverable or permanently destroyed. Other tests are needed to determine the cause of the stroke.

The nature, severity of symptoms, the patient’s history, its risk factors, age are the first elements of diagnosis. The doctor should also quickly determine:

Circus Challenge game

If this is ischemic (obstruction of a blood vessel by a clot, which reduces the blood flow in a brain area); Hemorrhagic accident (also known as cerebral haemorrhage or cerebral hematoma) following the rupture of a cerebral vessel. In this case, the blood spreads and damages the brain tissue around; Continue reading “What tests for what diagnosis?”

AVC: intervene quickly to diminish the legacy

Cerebral vascular accidents (CVAS) are the third cause of death in industrialized countries, after cancer and myocardial infarction, and are a major source of disability. Early treatment and rehabilitation measures tailored to improve the prognosis after such an accident.

The prognosis depends on for much of the importance of the accident and the affected brain area. But the rapid support and rehabilitation is also essential to reduce the risk of death and sequelae.

intervene quickly to diminish the legacy

The experts stressed the need to consider the stroke as an extreme emergency, in the same way as myocardial infarction. Indeed, brain cells do not long surviveischemia (judgment of blood supply). Measures to restore the traffic must be applied in the first hours following the accident to be likely to be effective. Continue reading “AVC: intervene quickly to diminish the legacy”

Arteries in three dimensions

We all have our arteries age. Known, these vessels may be, at the age of twenty, atherosclerosis-prone fats coming to settle within their walls. British scientists come to open a new avenue to explore. Thanks to their work, you can now get an image in three dimensions of the large arteries without trauma no, what could better monitor patients with a cardiovascular risk.

Currently, doctors can look at arteries and arterial flow in two dimensions through the Arteriography or, increasingly, the ultrasound and the Doppler, these last two methods with the interest to be dangerous and non-aggressive to the patients. At Imperial College London, the team of Dr. x. Xu Yun goes however already further. By coupling the magnetic resonance (MRI), ultrasound imaging, these researchers were able to images in three dimensions of large vessels.

Arteries in three dimensions

A simple review of the anatomy of the arteries
These scientists have initially focuses their efforts on major arteries like aorta or carotid bifurcations, because we know for a long time that the turbulence in the bloodstream foster, at this level, deposition of lipids. It is not uncommon that atherosclerosis develops in the neck at the level of the division of the elderly carotid arteries, and it was at the origin of a stroke and sometimes a hemiplegia. By combining MRI and ultrasound, and with the help of a computer, the anatomy of these arteries could be rebuilt.

A vision of the characteristics of blood flow
With this new method of imaging, British researchers were able to analyze three-dimensional structure of the carotid arteries and the aorta, including their wall and better study how they give training to other ships. Without penetrating inside them, capacity flexibility and elasticity of these vessels were evaluated, their mechanical properties determined. Finally, they were able to appreciate how fast blood flows through the artery, that this fluid undergoes (vortices flow…), forces exerted on the walls of the artery. As much valuable information to better understand the function of the arteries to the normal state and, above all, to better appreciate the impact of atherosclerosis in patients.

Indeed, it is essential to be able to estimate the probability that an artery is obstructed by atherosclerosis lesions. This phenomenon might then cause a stroke, depending on body areas, vascular disease or heart disease.

To follow…
For now, it is still only a method used for the purpose of research. But, of course, the next step should be to analyse the performance of patients. Fruitful results that would help save lives.

AVC: research advances on all fronts

Cerebral vascular accidents (CVAS) are the third cause of mortality in France. Each year, some 125,000 accidents occur as well in France, resulting in 50,000 deaths. Although research in this area is less publicized than cancer or genetic diseases, scientists argue on several fronts. Doctissimo presents some of the latest discoveries.

English neurologists called in May 2001, in the prestigious review medical The Lancet1 to re-evaluate funds for stroke research. According to the authors, the ageing of the population will lead to an explosion in the number of strokes in the next two decades. Despite these alarming forecasts collected across the channel and funds devoted to research in this field remain low compared to those mobilized against cardiovascular disease and cancer: 2.5 million pounds per year for stroke, against 43 for cardiovascular diseases and 120 for cancer.

research advances on all fronts

Despite this lack of awareness of the general public for the strokes, medical research periodically offers breakthroughs both in terms of prevention and therapy. Doctissimo presented you some. Continue reading “AVC: research advances on all fronts”

Recurrence of stroke: treatment do exist!

The World Health (who) Organization, nearly 5 million people die each year of cerebral vascular accident (stroke) suites and 15 million people keep the legacy. A balance sheet even more alarming that approximately 20% of survivors will be victims of a recurrence in five years in the form of another stroke or a myocardial infarction. Relapse prevention seems to be a major public health issue. A study published on September 29, 2001 in the Lancet shows the effectiveness of the treatments in this prevention.

Strokes are the third cause of mortality. The balance sheet appears alarming: half of patients die in the medium term. On the other hand, survivors remain for half of them (i.e. 25% of the total), very disabling mental and physical sequelae.

treatment do exist!

The remaining quarter will generally have less important sequelae that are not without impact. Among these, there is a high proportion of nervous breakdowns. With the aging of the population, the strokes are as early as today a real public health issue.

The preventive treatments are available…
After the occurrence of a first stroke, the most widely recognized preventive treatment is based on coagulation inhibitors medications: of platelet aggregation. Continue reading “Recurrence of stroke: treatment do exist!”
