A bad headache. Difficulty focusing. Confusion or fumbling to find words. It’s tempting to explain away troubling symptoms and chalk them up to fatigue, eye trouble, one too many cups of coffee. But these symptoms – particularly if they’re severe – may signal a stroke.Stroke is the third leading cause of death, behind cancer and heart disease. A disease that affects the blood supply to the brain, stroke occurs when a blood vessel or artery is blocked by a blood clot or bursts. when this happens, the area of the brain that is supplied with oxygen and nutrients by this blood vessel is damaged. as a result, the body part or function controlled by this part of the brain doesn’t operate the right way.another frightening statistic: according to the National Stroke Association, people who have a stroke are four times as likely to have another stroke during their lifetime. Recurrent strokes carry an even higher risk of death and disability because the brain has previously been injured by the original stroke.A stroke can change a person’s life forever. it can leave the victim with moderate to severe physical, mental or psychological disabilities. Depending on the area of the brain affected, a stroke victim may lose their memory, speech, balance, certain fine motor skills, control over certain muscles or movement of entire limbs – even paralysis of one side of the body. A person’s personality or behavior can be forever changed by a stroke. they may have difficulty reading, processing information or even eating.About 87 percent of all strokes are ischemic strokes, where a blockage of a blood vessel that supplies blood to the brain occurs. the clot can form in the brain area, or in a blood vessel elsewhere in the body – the heart, chest area or neck – where it can break loose and travel to the brain. the remaining 13 percent are called hemorrhagic strokes – strokes caused by a weakened blood vessel that breaks and bleeds into the surrounding brain tissue. A brain aneurysm refers to the bulging of the weakened blood vessel, which continues to weaken and, if not treated, breaks and bleeds into the brain.if you suspect that someone is having a stroke, act quickly. A stroke is an emergency – and mere seconds can make an enormous difference in the outcome for a stroke survivor. call 9-1-1 and try to recall the time that symptoms first appeared. if a stroke victim receives immediate medical assistance, a clot-busting drug can be administered by medical personnel within three hours of first symptoms which may reduce the likelihood of long-term disability resulting from a stroke. the quicker that medical care is received, the greater a stroke victim’s chances are of not only surviving a stroke, but minimizing its effects.Learn to recognize stroke signs, and be prepared – to save a friend or loved one’s life, or your own.Warning Signs of a Stroke• Sudden numbness or weakness of the face, arm or leg, especially on one side of the body.• Sudden confusion, trouble speaking or understanding.• Sudden trouble seeing in part of one’s visual field.• Sudden trouble walking, dizziness, loss of balance or coordination.• Sudden, severe headache with no known cause.Not all of these warning signs may be present, and one or more may go away. Don’t ignore these signs or dismiss them, even if they do not persist. call 9-1-1 or seek medical assistance immediately.this information is not intended to replace the advice of your doctor, but rather to increase awareness and help equip patients with information and facilitate conversations with your physician that will benefit your health.Editor’s note:  this information was writte and provided by Dr. Allen Tyler.  Dr. Tyler is a member of the medical staff at Pottstown Memorial Medical Center, Department of Internal Medicine – Neurology.  he is a graduate of the University of Pennsylvania, and received his medical degree from Jefferson Medical College.  he also completed a postgraduate Fellowship in Neurophysiology & Epilepsy at Thomas Jefferson University Hospital.  he is a member of the American Academy of Neurology; the American Clinical Neurophysiology Society; the American College of Physicians; American Society of Internal Medicine and the American Epilepsy Society.
