Heart and Stroke Penticton - The medical condition called a stroke is the quickly developing loss of brain function which happens by disturbances in the brain's blood supply. Strokes may be a result of thrombosis blockage or an arterial embolism, and can be a result of lack of blood flow (ishchemia) or could come as a result of haemorrhage or blood leakage. A stroke is a medical emergency which needs immediate care. It can cause permanent complications, neurological damage and demise.
The affected part of the brain loses normal functioning, when a stroke takes place. These can manifest in the loss of visual field in one side of the body, loss of limb movement on one side of the body, or an inability to formulate or understand speech. A stroke was formerly called a CVA cerebrovascular accident.
Stroke is the leading reason for disability within the USA and Europe. It is also the 2nd leading reason for fatality in the globe. Some risk factors for stroke comprise: high blood pressure or hypertension, old age, high cholesterol, previous stroke, TIA or likewise known as transient ischemic attack, smoking and arterial fibrillation. The most important modifiable risk factor for stroke is high blood pressure.
A silent stroke happens when the individual is not aware they have suffered a stroke and they do not have whatever outward symptoms. Even if certain symptoms are not caused during a silent stroke, this incident still results in brain damage. It also places the patient at an increased risk for both a major stroke in the future and for transient ischemic attack. Also, people who have suffered a major stroke before are at risk of having silent stroke.
Usually silent strokes cause lesions on the brain that are detected through using neuro-imaging techniques such as MRI. It is projected that silent stroke happens at five times the rate of symptomatic stroke. The risk of stroke becomes higher with age and it may also affect adults and younger kids, specially those who suffer acute anaemia.
Hospitals would usually treat an ischemic stroke with a "clot buster," or thrombolysis. In order to treat hemorrhagic strokes, some can benefit from neurosurgery. Stroke rehabilitation is used in reference to recover and treat whichever lost function. Normally, this occurs in a stroke unit and involves several health care practitioners like for example language therapists, speech therapists and physical and occupational therapists. The administration of anti-platelet drugs including dipyridamole and aspirin can help prevent a recurrence. Using statins and the reduction and control of hypertension can also contribute to prevention. Certain people can benefit from using anticoagulants and carotid endarterectomy.
