The most widely known and the only FDA-approved drug for treatment of ischemic stroke — intravenous tPA (tissue plasminogen activator) — can reverse stroke if given to carefully selected patients within a few hours of stroke onset.
With stroke, “time is brain,” meaning that the sooner treatment begins, the better. Knowing the signs of stroke and calling 911 immediately can help save a relative, neighbor, or friend. With timely treatment it is possible to save these cells and greatly reduce and reverse the damage.
The short answer is yes, stroke can be cured — but it occurs in two stages. First, doctors administer specific treatment to restore normal blood flow in the brain and stop further damage. Then, the patient participates in rehabilitation to cure the secondary effects that result from the stroke.
A clot-busting medication called tPA, or tissue plasminogen activator, can be given to someone if they're having a stroke, potentially reversing or stopping symptoms from developing.
Most people will be given aspirin straight after having an ischaemic stroke. As well as being a painkiller, aspirin is an antiplatelet, which reduces the chances of another clot forming. Other antiplatelet medicines may be used later, such as clopidogrel and dipyridamole.
How Does a Stroke Impact Life Expectancy? Despite the likelihood of making a full recovery, life expectancy after stroke incidents can decrease. Unfortunately, researchers have observed a wide range of life expectancy changes in stroke patients, but the average reduction in lifespan is nine and a half years.
Gains can happen quickly or over time.
The most rapid recovery usually occurs during the first three to four months after a stroke, but some survivors continue to recover well into the first and second year after their stroke.
Few patients recover fully and most are left with some disability, but the majority exhibit some degree of spontaneous recovery. Doctors and scientists don't fully understand how this happens, because the brain does not grow new cells to replace the ones damaged by the stroke.
Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke. One study found that 43% of stroke patients experienced mini-stroke symptoms up to a week before they had a major stroke.
Thrombectomy can be performed up to 24 hours after a stroke, but it is most effective in the first six hours. Juliet Bouverie, chief executive of the Stroke Association, said: "Thrombectomy is a miracle treatment that pulls patients back from near-death and alleviates the worst effects of stroke.
An MRI can also detect old strokes for decades after they happen. The fastest type of MRI is diffusion-weighted imaging (DWI). It measures shifts in fluid in the brain and can detect a stroke soon after its onset. An MRI can also detect evidence of past strokes.
Even after surviving a stroke, you're not out of the woods, since having one makes it a lot more likely that you'll have another. In fact, of the 795,000 Americans who will have a first stroke this year, 23 percent will suffer a second stroke.
Stress can cause the heart to work harder, increase blood pressure, and increase sugar and fat levels in the blood. These things, in turn, can increase the risk of clots forming and travelling to the heart or brain, causing a heart attack or stroke.
For example, 79% of people survive 2 years, 61% survive 3 years, …, 5% survive 16 years, and only 1% survive 20 years.
Medical experts often use the NIH Stroke Scale to determine the severity of a stroke. Patients that score between 21 and 42 (the highest possible score) are considered to have suffered a massive stroke.
On average, between 10 and 15 years after stroke, 25% of survivors were moderately-severely disabled, 21% were inactive, 22% had cognitive impairments, 32% were anxious and 38% depressed. Functional, cognitive and psychological outcomes between 10 and 15 years after stroke.
Although just 10% of people fully recover from a stroke, 25% have only minor impairments and 40% have moderate impairments that are manageable with some special care.
The reason the first hour is golden is because stroke patients have a much greater chance of surviving and avoiding long-term brain damage if they arrive at the hospital and receive treatment with a clot-busting drug called TPA within that first hour.
Unfortunately, the blood thinners used to prevent such blood clots can increase the risk of bleeding in the brain, a cause of hemorrhagic stroke.
The major risk factors for stroke include: High blood pressure. Diabetes. Heart and blood vessel diseases: Conditions that can cause blood clots or other blockages include coronary heart disease, atrial fibrillation, heart valve disease, and carotid artery disease.
