St. Francis-Emory Healthcare's team of healthcare professionals has earned national recognition for providing outstanding care for stroke patients including:
According to the National Stroke Association (NSA), it's important to learn the three R's:
Stroke is an emergency and should be treated as such. The greatest chance for recovery from stroke occurs when emergency treatment is started immediately.
Stroke is the fourth leading cause of death, ranking behind diseases of the heart, lungs, and all forms of cancer. According to the NSA, strokes kill more than 137,000 Americans each year.
Stroke, also called brain attack, occurs when blood flow to the brain is disrupted. Disruption in blood flow is caused when either a blood clot blocks one of the vital blood vessels in the brain (ischemic stroke), or when a blood vessel in the brain bursts, spilling blood into surrounding tissues (hemorrhagic stroke).
The brain needs a constant supply of oxygen and nutrients in order to function. Even a brief interruption in blood supply can cause problems. Brain cells begin to die after just a few minutes without blood or oxygen. The area of dead cells in tissues is called an infarct. Due to both the physical and chemical changes that occur in the brain with stroke, damage can continue to occur for several days. This is called a stroke-in-evolution.
A loss of brain function occurs with brain cell death. This may include impaired ability with movement, speech, thinking and memory, bowel and bladder, eating, emotional control, and other vital body functions. Recovery from stroke and the specific ability affected depends on the size and location of the stroke. A small stroke may result in problems such as weakness in an arm or leg. Larger strokes may cause paralysis (inability to move part of the body), loss of speech, or even death.
The following are the most common symptoms of stroke. However, each individual may experience symptoms differently. If any of these symptoms are present, call 911 (or your local ambulance service) immediately. Treatment is most effective when started immediately.
Symptoms may be sudden and include:
All of the above warning signs may not occur with each stroke. Do not ignore any of the warning signs, even if they go away--take action immediately. The symptoms of stroke may resemble other medical conditions or problems. Always consult your doctor for a diagnosis.
Other, less common, symptoms of stroke may include the following:
Strokes can be classified into two main categories:
An ischemic stroke occurs when a blood vessel that supplies the brain becomes blocked or "clogged" and impairs blood flow to part of the brain. The brain cells and tissues begin to die within minutes from lack of oxygen and nutrients. The area of tissue death is called an infarct. About 87 percent of strokes fall into this category. Ischemic strokes are further divided into two groups, including the following:
Thrombotic strokes are strokes caused by a thrombus (blood clot) that develops in the arteries supplying blood to the brain. This type of stroke is usually seen in older persons, especially those with high-cholesterol levels and atherosclerosis (a buildup of fat and lipids inside the walls of blood vessels).
Sometimes, symptoms of a thrombotic stroke can occur suddenly and often during sleep or in the early morning. At other times, it may occur gradually over a period of hours or even days. This is called a stroke-in-evolution.
Thrombotic strokes may be preceded by one or more "mini-strokes," called transient ischemic attacks, or TIAs. TIAs may last from a few minutes to a few days and are often a warning sign that a stroke may occur. Although usually mild and transient, the symptoms caused by a TIA are similar to those caused by a stroke.
Another type of stroke that occurs in the small blood vessels in the brain is called a lacunar infarct. The word lacunar comes from the Latin word meaning "hole" or "cavity." Lacunar infarctions are often found in people who have diabetes or hypertension (high blood pressure).
Embolic strokes are usually caused by an embolus (a blood clot that forms elsewhere in the body and travels through the bloodstream to the brain). Embolic strokes often result from heart disease or heart surgery and occur rapidly and without any warning signs. About 15 percent of embolic strokes occur in people with atrial fibrillation, a type of abnormal heart rhythm in which the upper chambers of the heart do not beat effectively.
Hemorrhagic strokes occur when a blood vessel that supplies the brain ruptures and bleeds. When an artery bleeds into the brain, brain cells and tissues do not receive oxygen and nutrients. In addition, pressure builds up in surrounding tissues and irritation and swelling occur. About 13 percent of strokes are caused by hemorrhage. Hemorrhagic strokes are divided into two main categories, including the following:
Intracerebral hemorrhage is usually caused by hypertension (high blood pressure), and bleeding occurs suddenly and rapidly. There are usually no warning signs and bleeding can be severe enough to cause coma or death.
Subarachnoid hemorrhage results when bleeding occurs between the brain and the meninges (the membrane that covers the brain) in the subarachnoid space. This type of hemorrhage is often due to an aneurysm or an arteriovenous malformation (AVM).
Rehabilitation of the patient with a stroke begins during the acute treatment phase. As the patient's condition improves, a more extensive rehabilitation program is often begun.
The outlook for stroke patients today is more hopeful than ever due to advances in both stroke treatment and rehabilitation. Stroke rehabilitation works best when the patient, family, and rehabilitation staff works together as a team. Family members must learn about impairments and disabilities caused by the stroke and how to help the patient achieve optimal function again.
The goal of stroke rehabilitation is to help the patient return to the highest level of function and independence possible, while improving the overall quality of life--physically, emotionally, and socially. Rehabilitation is designed to meet each person's specific needs; therefore, each program is different. Some general treatment components for stroke rehabilitation programs include the following:
According to the National Institute of Neurological Disorders and Stroke, in general, there are several types of disabilities that stroke can cause: paralysis or problems controlling movement such as walking or balance and/or swallowing; sensory (ability to feel touch, pain, temperature, or position) disturbances; difficulty using or understanding language; thinking and memory problems, and emotional disturbances. Stroke rehabilitation can help you recover from the effects of stroke, relearn skills, and new ways to perform tasks and depends on many variables, including the following:
Areas covered in stroke rehabilitation programs may include:
|Self-care skills, including activities of daily living (ADLs)
|Feeding, grooming, bathing, dressing, toileting, and sexual functioning
|Walking, transfers, and self-propelling a wheelchair
|Speech, writing, and alternative methods of communication
|Memory, concentration, judgment, problem solving, and organizational skills
|Interacting with others at home and within the community
|Medications and alternative methods of managing pain
|Identifying problems and solutions with thinking, behavioral, and emotional issues
|Assistance with adapting to lifestyle changes, financial concerns, and discharge planning
|Patient and family education and training about stroke, medical care, and adaptive techniques
The stroke rehabilitation team revolves around the patient and family and helps set short- and long-term treatment goals for recovery. Many skilled professionals are part of the neurology rehabilitation team, including any or all of the following:
