The Centers for Disease Control and Prevention (CDC) estimates that 610,000 Americans have their first stroke out of the over 795,000 who experience one each year in the United States. With 11 percent of deaths worldwide in 2019, stroke was the second most common cause of death. Stroke comes in three primary forms. The first type of stroke is the most prevalent, making up 87% of cases. It happens when an artery supplying the brain with oxygen loses its ability to carry blood. The second type of stroke is known as a hemorrhagic stroke, which is brought on by a brain artery burst that subsequently injures nearby tissues.

A transient ischemic attack (TIA), referred to as a ministroke, is the third stroke category. It occurs when there is a brief interruption in blood supply to the brain, usually lasting no longer than five minutes. Despite being extremely common, stroke is frequently misinterpreted. We consulted with Dr. Rafael Alexander Ortiz, chief of Neuro-Endovascular Surgery and Interventional Neuro-Radiology at Lenox Hill Hospital, to clear up misconceptions and deepen our understanding of the subject.

Stroke is a problem of the heart
Strokes occur in the brain, not the heart, although cardiovascular risk factors are linked to stroke risk. Dr. Ortiz told MNT that some people believe that heart problems are the cause of stroke. That’s not correct. A stroke is not a heart issue; rather, it is a brain issue brought on by an obstruction or rupture of cerebral arteries or veins. Heart attacks, which are brought on by a blockage in the blood supply to the heart rather than the brain, are sometimes confused with strokes.

Stroke is not preventable
According to Dr. Ortiz, the most prevalent risk factors [for stroke] are high blood pressure, smoking, high cholesterol, obesity, diabetes, head or neck trauma, and cardiac arrhythmias. A lot of these risk factors are modifiable through lifestyle choices. Regular exercise and a balanced diet help lower risk factors like diabetes, high blood pressure, obesity, and obesity. Stress and alcohol use are two more risk factors. A person’s chance of stroke may be decreased by making efforts to lessen or eliminate these lifestyle factors.

Stroke does not run in families
A person’s risk of stroke is increased by single-gene diseases like sickle cell disease. The risk of stroke may also be indirectly increased by genetic factors, such as an increased propensity for high blood pressure and other cardiovascular risk factors. Unhealthy lifestyle choices are likely to raise the risk of stroke in family members since families frequently share environments and lifestyles, particularly when combined with genetic risk factors.

Stroke symptoms are hard to recognize
The most common symptoms for stroke form the acronym F.A.S.T.
F: face dropping, when one side of the face becomes numb and produces an uneven smile
A: arm weakness, when one arm becomes weak or numb and, when raised, drifts slowly downward
S: speech difficulty, or slurred speech
T: time to call 911
Other symptoms of stroke include: The symptoms may include numbness or weakness in one or both eyes; confusion; trouble speaking or understanding speech; difficulty walking, including dizziness, loss of balance, and coordination; and severe headaches without a known cause.

Stroke cannot be treated
Dr. Ortiz clarified that there is a false belief that strokes are incurable and untreatable. Many stroke patients can have their symptoms reversed by emergency treatment with a clot-busting drug injection, minimally invasive mechanical thrombectomy for clot removal, or surgery, he noted. This is especially true if the patient arrives at the hospital early enough for the therapy (within minutes or hours since the onset of the symptoms). The chance of a positive result decreases with the duration of the symptoms. As a result, it’s imperative that at the first sign of a stroke, ie. He went on, “If you’re having problems speaking, double vision, paralysis, numbness, etc., call 911 to send an ambulance to the closest hospital.”. Additionally, studies reveal that people who visit within three hours of the onset of symptoms usually experience less disability three months later than people who arrive later.

Stroke occurs only in the elderly
One major risk factor for stroke is age. After age 55, the risk of stroke doubles every ten years. Strokes, however, can happen at any age. According to a study that looked at medical data, 34% of stroke hospitalizations in 2009 involved people under the age of 65. According to a 2013 review, young adults and adolescents account for 15% of all ischemic stroke cases. The most prevalent co-existing conditions in this age group, according to the researchers, were lipid disorders, obesity, diabetes, hypertension, and tobacco use all stroke risk factors.

All strokes have symptoms
Not every stroke has symptoms, and some studies indicate that strokes without symptoms occur far more frequently than strokes with symptoms. According to one study, of the approximately 11 million strokes that occurred in 1998, 770,000 had symptoms, while nearly 11 million did not. Evidence of these so-called silent strokes appears on MRI scans as white spots from scarred tissue following a blockage or ruptured blood vessel. When patients undergo MRI scans for symptoms like headaches, cognitive problems, or dizziness, silent strokes are frequently discovered. Even though they don’t have any symptoms, they should be treated in the same way as strokes that do. People who have silent strokes are more vulnerable to dementia, cognitive decline, and subsequent symptomatic strokes.

A ministroke is not so risky
According to Dr. Ortiz, the term “ministroke” has been misused because some people believe it to refer to small, low-risk strokes. That is untrue because a ministroke is actually a transient ischemic attack (TIA). This is not a minor stroke; rather, it is a warning sign that a major stroke could happen. He continued, “Any acute stroke symptom, whether temporary or persistent, requires emergency workup and management to prevent a devastating large stroke.

Stroke always causes paralysis
A stroke is one of the most common causes of permanent disability; however, not all stroke victims will become paralyzed or weak. Studies reveal that more than half of stroke survivors 65 and older have decreased mobility as a result of their stroke. However, many variables, including the location and extent of brain tissue damage, affect how a stroke affects a person in the long run. For instance, harm to the left brain will impact the right side of the body and vice versa. Effects of a stroke that happens on the left side of the brain might include memory loss, speech and language difficulties, paralysis on the right side of the body, and slow, cautious behavior. Paralysis may also happen, but on the left side of the body, if it impacts the right side of the brain. Other side effects could be memory loss, rapid and curious behavior, vision issues, or both.

Stroke recovery happens fast
After a stroke, recovery may take several months or even years. Many, though, might not fully recover. According to the American Stroke Association, of those who survive a stroke, 10% will recover almost completely, 10% will need care in a long-term facility or nursing home, 25% will recover with minor impairments, and 40% will experience moderate to severe impairments. Research indicates that there may be a critical window of 2-3 months following the onset of the stroke, during which intensive motor rehabilitation is more likely to result in recovery. During this time, some people might also be able to recover on their own. Although they are likely to occur much more slowly, improvements are still possible after this window and the 6-month point.
