Stroke is a half sided paralysis occurs that results from a certain area of brain damage due to interruption of blood supply.
Interruption of blood supply to the brain may be due to a thrombus (step wise development
of paralysis - 75% cases), Hemorrhage (explosive onset of paralysis - 25% cases), Embolus
(bolt from the blue-rare). For years, strokes have been subdivided pathologically into infarcts (thrombotic or embolic) and hemorrhages, and clinical criteria for distinguishing between these possibilities have been emphasized. However, diabetes develops when the pancreas does not make enough insulin, or the cells in the muscles, liver, and fat do not use insulin properly, or both. The good news is that many fewer Americans now die of strokes than was the case 20 or 30 years ago. Improvement in the control of major risk factors for stroke smoking, high blood pressure and high cholesterol is likely responsible for the decline.
The brain consumes oxygen at the rate of 3.5 ml per 100 gm and glucose at the rate of 5mg
; per100 gm. Any disruption in this supply leads to brain damage. For years, strokes have been subdivided pathologically into infarcts (thrombotic
or embolic) and hemorrhages, and clinical criteria for distinguishing between
these possibilities have been emphasized. However, it is often difficult to
determine on clinical grounds the pathologic basis for stroke
Stroke is a half sided paralysis occurs that results from a certain area of brain damage due to interruption of blood supply. Prompt treatment of a stroke could mean the difference between life and death. One of the strategies to respond to the challenges to population health and well being due to the global epidemic of heart attack and stroke is to provide actionable information for development and implementation of appropriate policies. It is characterized by pain episodes, anemia (shortage of red blood cells), serious infections and damage to vital organs. Stroke is a medical emergency. But in sickle cell disease, the abnormal hemoglobin causes red blood cells to become stiff and, under the microscope, may look like a C-shaped farm tool called a sickle. They are dedicated to taking heart and stroke research to the next level and, ultimately, to complete prevention or a cure.
Causes of Stroke Disease Information
The common Causes of Stroke Disease Information :
- A blood vessel carrying blood to the brain is blocked by a blood clot this is called an ischemic stroke .
- Hemorrhagic strokes tend to be more serious than ischemic strokes. Death occurs in 30-50% of people with this type of stroke.
- Inflammation of any part of the heart or major artery
- The most common cause of stroke in children is congenital cyanotic heart disease and sickle cell disease drugs, such as cocaine and amphetamines, can narrow the blood vessels and cause stroke.
- The risk of stroke is also increased by age, family history of stroke, smoking, diabetes, high cholesterol, and heart disease.
- Lack of Physical Activity
- A clot that breaks loose and moves through the bloodstream to the brain is called an cerebral embolism
- Ischemic strokes may also be caused by small blood clots or emboli that go through the bloodstream and then get clogged in an artery when the artery narrows these clots can come from pieces of plaques in the bigger arteries that break off or from the heart.
Some common Symptoms of Stroke Disease Information :
- Swallowing difficulties or drooling.
- Loss of consciousness you may become unconscious, stuporous, or hard to arouse and could die.
- Numbness , tingling , decreased sensation.
- Shortness of breath
- Weakness or paralysis of an arm, leg, side of the face, or any part of the body.
- Loss of memory.
- Dizziness you may feel drunk or dizzy or have difficulty swallowing.
- Sudden nausea, vomiting, or fever not caused by a viral illness.
- Difficulty speaking you can't speak, speech may be very slurred, or when you speak, the words sound fine but do not make sense.
- Brief loss or change of consciousness such as fainting, confusion, seizures, or coma.
Treatment of Stroke Disease Information
Here is the list of the methods for treating Stroke Disease Information :
- Taking medication to treat any underlying conditions, such as stroke, high blood pressure, high cholesterol, diabetes or heart problems.
- Current treatments for acute stroke must be given by a doctor and within a short time of the onset of symptoms. It is crucial for the person experiencing a stroke to get to the emergency department as quickly as possible to get the most benefit from any treatment.
- Adopting a healthier lifestyle by stopping smoking, taking regular exercise, eating healthily and only drinking alcohol in moderation
- Physicians have begun to call it a "brain attack" to stress that getting treatment immediately can save lives and reduce disability.
- Receiving rehabilitative support, such as physiotherapy, occupational therapy and speech therapy, to help the person maximise their opportunities to regain their lost functions.
- Medications of this type are called neuroprotective agents, with some still under investigation in clinical trials.
- Corticosteroids and special types of intravenous (IV) fluids are often used to help reduce or control brain swelling, especially after a hemorrhagic stroke (a stroke caused by bleeding into the brain).
