ACV
Hi, to start the blog post in English, here we bring you the acv medical information.
It produces a stroke ( CVA) when the blood supply to part of the brain is suddenly blocked or when a blood vessel in the brain bursts , spilling blood into the spaces surrounding brain cells . In the same way it is said that a person suffering a loss of blood flow to the heart has a heart attack, it is said that a person suffering a loss of blood flow to the brain or sudden bleeding in the brain has a "brain attack " .
Paralysis is a common feature of stroke , often on one side of the body ( hemiplegia ) . The paralysis or weakness may affect only the face, arm or leg, or one side can affect the entire body and face .
A person suffering a stroke in the left hemisphere of the brain show paralysis or paresis of the right side . Conversely , a person suffering a stroke in the right hemisphere paralysis or paresis show izquierdo.Isquemia side is the term used to describe the lack of oxygen and nutrients to brain cells when there is inadequate blood flow . Ischemia ultimately cause a heart attack, death of brain cells, which are ultimately replaced by a fluid filled cavity ( or stroke ) in the injured brain .
When stopping blood flow to the brain, some brain cells die immediately and others are at risk of death . Damaged cells can be saved with early pharmacological intervention . Researchers have found that we can achieve restoring blood flow to these cells by administering the clot-dissolving agent tissue plasminogen activator (t -PA ) within 3 hours after stroke onset . Are being tested many neuroprotective drugs to prevent further damage wave of initial attack .
The ACV has always been considered unpredictable and untreatable. Added to this fatalism was the mistaken belief that stroke only occurs in older people and , therefore , no cause for concern.
As a result of these misconceptions , the average stroke patient waits more than 12 hours to get to an emergency room . Health care providers have an attitude of "watchful waiting" rather than trying to stroke as a medical emergency .
With the use of the term "brain attack " , stroke has a definite and descriptive name . The proper response to a brain attack is emergency action , on the part of the person concerned and the medical community . It is crucial to educate the public to treat stroke as a brain attack and to seek emergency treatment because every minute lost , from the beginning of symptoms to the time of contact with emergency care , shrinking the limited window of opportunity for intervention .
Symptoms
The symptoms of stroke are easy to spot : sudden numbness or weakness , especially on one side of the body, sudden confusion or trouble speaking or understanding spoken , sudden trouble seeing in one or both eyes , sudden trouble walking, dizziness or loss of balance or coordination , severe headache with no known cause and sudden . A stroke can usually be distinguished from other causes of dizziness or headache. These symptoms may indicate that there has been a stroke and needed immediate medical attention .
Risk Factors
The most important risk factors for stroke are hypertension , heart disease , diabetes and smoking . Others include heavy alcohol consumption , high cholesterol levels in blood, illegal drug use and genetic or congenital conditions , particularly vascular abnormalities.
early Recovery
In ways that are not clearly understood , the brain compensates for the damage caused by stroke or brain attack . Some brain cells may be only temporarily damaged , not dead , and can resume operation . In some cases , the brain can reorganize its own functioning. Sometimes , a brain region is damaged by another stroke. People who survive a stroke experience sometimes striking and unexpected recoveries inexplicable .
The general pattern of recovery shown :
* 10 percent of stroke survivors recover almost completely
* 25 percent recover with minor alterations
* 40 percent suffer moderate to severe disorders that require special care
* 10 percent require care in an institution for long-term care
* 15 percent die shortly after the stroke
rehabilitation
Rehabilitation begins in the hospital as soon as possible after the stroke . In stable patients , rehabilitation may begin within two days after the stroke and the time should continue after discharge. Rehabilitation options may include rehabilitation unit of a hospital, sub-acute care unit to a rehabilitation hospital, home care , outpatient care or long-term care in an appropriate institution .
The goal of rehabilitation is to improve function so that the person who survives a stroke can be as independent as possible . This should be achieved in a manner that preserves dignity while motivating the patient to relearn basic skills that hit the attack , such as eating , dressing and walking .
Although stroke is a disease of the brain, it can affect the entire body. Some of the disabilities that can result from stroke include paralysis , cognitive deficits , speech problems, emotional difficulties , daily living problems and pain.
Stroke may cause problems with thinking , awareness , attention , learning , judgment and memory. A stroke patient may not be aware of your surroundings or may not be aware of the mental deficiencies that caused the stroke.
Stroke victims often have trouble understanding speech or issue . Language problems are usually caused by damage to the left temporal and parietal lobes of the brain.
A stroke can lead to emotional problems. Stroke patients may have difficulty controlling their emotions , or they may express inappropriate emotions in certain situations. A common disability that occurs with many stroke patients is depression , which is more than a general sadness resulting from stroke incident .
Stroke patients may experience pain, numbness uncomfortable or odd sensations after the attack. These feelings may be due to many factors, including damage to the sensory regions of the brain, joint stiffness or disability of a member.
According to the National Stroke Association (National Stroke Association ) , the total cost of stroke to the United States is about 43 billion dollars a year , with direct costs of medical care and therapy estimated at about 28 billion dollars per year .
