It is a rare blood vessel disease caused by blocked arteries in the brain. The name \u201cmoyamoya\u201d is derived from a Japanese term meaning \u201cpuff of smoke,\u201d because the tangle of vessels often resembles a small puff of smoke. Occurring in approximately 1 out of every 100,000 people, moyamoya disease can be fatal if left undiagnosed and untreated. It is estimated that people with Down syndrome are 26 times more likely to develop the disease, compared with the typical population. It is important for parents of children with Down syndrome to know the warning signs and next steps if their child is diagnosed.<\/p>\n<p><span style=\"color: #000080; padding: 0px 35px;\"><strong>A MOTHER\u2019S STORY<\/strong><\/span><\/p>\n<div class=\"magcov\" style=\"padding: 0px 0px 20px 0px;\"><a href=\"http:\/\/downsyndromeworld.org\/\"><br \/>\n<img decoding=\"async\" src=\"https:\/\/www.globaldownsyndrome.org\/wp-content\/uploads\/2019\/05\/dsw_cover_2019_issue_1_tilted.png\"><\/a><span style=\"color: #000;\">This article was published in the award-winning&nbsp;<a href=\"http:\/\/downsyndromeworld.org\/\">Down Syndrome World\u2122<\/a> magazine. <a href=\"http:\/\/downsyndromeworld.org\/membership\">Become a member<\/a> to read all the articles and get future issues delivered to your door! <\/span><\/div>\n<p style=\"color: #000; padding: 0px 35px;\">Maria Dellapina, from Burton, Ohio, is the founder of the award-winning adaptive eyewear company, Specs4Us. Her daughter, Erin Farragher, happens to have Down syndrome. When Erin was 16 years old, she began experiencing unusual symptoms of shaking , fainting, and muscle aches.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">\u201cErin called out to me, I turned around, and she was shaking all over and fell to the ground,\u201d recalls Dellapina. Initially, Dellapina thought her daughter had experienced a mini-stroke, but Erin bounced back quickly.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">However, Erin\u2019s symptoms continued to occur \u2014 more headaches, more muscle aches, and poor balance. In Dellapina\u2019s search for answers, she received an email from a parent, who, based on his experience with his daughter, advised Dellapina to look into moyamoya disease, a term with which she was unfamiliar.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">Growing increasingly concerned with Erin\u2019s \u201coff\u201d behavior over the next few days, Dellapina decided to take Erin to the emergency department at a local hospital.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">\u201cWhen I pulled into the parking lot, Erin star ted throwing up,\u201d Dellapina recalls. \u201cThe physicians thought Erin had the flu. They even laughed when I mentioned moyamoya.\u201d<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">Not convinced, Dellapina took Erin to another hospital in Cleveland. A CT scan revealed Erin had suffered from a stroke. In fact, it was just one of several strokes and transient ischemic attacks (TIAs), also called \u201cmini-strokes,\u201d that Erin had apparently experienced throughout her young life. Later, at Cleveland Clinic, an MRI and angiogram led physicians to diagnose Erin with moyamoya disease.<\/p>\n<p><span style=\"color: #000080; padding: 0px 35px;\"><strong>LEARNING ABOUT MOYAMOYA<\/strong><\/span><\/p>\n<p style=\"color: #000; padding: 0px 35px;\">Anytime families receive an unexpected diagnosis, it can be very overwhelming and scary. Knowing the facts and what to expect can help ease some of that fear. Moyamoya disease occurs when the internal carotid arteries at the front of the neck that supply the brain with oxygenated blood gradually narrow, says Raphael Sacho, M.D., F.R.C.S., Assistant Professor of Neurosurgery at the Medical College of Wisconsin. As those vessels narrow, the two vertebral arteries at the back of the neck compensate by developing small blood vessels called collaterals. This causes a tangling of blood vessels in the brain, restricting blood flow.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">\u201cCollaterals take over the function of the internal carotid arteries over time,\u201d Dr. Sacho explains. \u201cThat, in itself, can cause problems because the collaterals can be small, thin, and not used to taking so much blood. They can burst and cause bleeding.\u201d<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">As a result, many people with moyamoya disease experience strokes, just as Erin did. All types of strokes share symptoms such as headaches, seizures, visual disturbances, one-sided weakness, slurred speech, involuntary movements, and cognitive impairment. Some common strokes that occur with people who have moyamoya disease are TIAs, ischemic strokes, and hemorrhagic strokes. TIAs occur when blood flow to the brain is interrupted briefly but then resumes, which is why they are often called \u201cmini-strokes.\u201d Ischemic strokes occur as a result of a blood clot completely blocking an artery that supplies the brain with blood. Hemorrhagic strokes \u2014 major brain bleeds \u2014 may occur if blood vessels or collaterals burst.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">The reason people with or without Down syndrome develop moyamoya disease is unclear.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">It\u2019s thought that genetics may play a role, as several mutations to the gene RNF213 are associated with moyamoya disease. Infection or inflammation may also be involved in its development, according to the National Institutes of Health (NIH).<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.globaldownsyndrome.org\/wp-content\/uploads\/2019\/05\/moyadsw02.png\" alt=\"\" width=\"700\" class=\"aligncenter size-full wp-image-55044\" srcset=\"https:\/\/www.globaldownsyndrome.org\/wp-content\/uploads\/2019\/05\/moyadsw02.png 1172w, https:\/\/www.globaldownsyndrome.org\/wp-content\/uploads\/2019\/05\/moyadsw02-600x288.png 600w, https:\/\/www.globaldownsyndrome.org\/wp-content\/uploads\/2019\/05\/moyadsw02-768x369.png 768w, https:\/\/www.globaldownsyndrome.org\/wp-content\/uploads\/2019\/05\/moyadsw02-390x187.png 390w, https:\/\/www.globaldownsyndrome.org\/wp-content\/uploads\/2019\/05\/moyadsw02-464x223.png 464w\" sizes=\"(max-width: 1172px) 100vw, 1172px\" \/><br \/>\n<span style=\"color: #000; font-family: trebuchet ms; font-size: 12px;\"><em>Mary Beth Freckmann and her daughter, Madie Ehlers<\/em><\/span><\/p>\n<p><span style=\"color: #000080; padding: 0px 35px;\"><strong>PREVALENCE AND THE IMPORTANCE OF EARLY DETECTION<\/strong><\/span><\/p>\n<p style=\"color: #000; padding: 0px 35px;\">\u201cIn the United States, it was thought moyamoya disease occurred in 0.1 per 100,000 people,\u201d says Gary Steinberg, M.D., Ph.D., Chair of Neurosurgery, Director of the Stanford Moyamoya Center, and Founder and Co-Director of the Stanford Stroke Center. \u201cMore recent studies have shown the incidence may be 0.5 or closer to 1 per 100,000 because it\u2019s been under-recognized in the U.S.\u201d<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">While the disease is rare in the general population, people with Down syndrome are 26 times more likely to develop the disease than typical people, according to Dr. Sacho. The reasons for that discrepancy are also unclear, though signs seem to point to genetics. He adds that, in Down syndrome, there\u2019s something about the triplication of chromosome 21 (the defining characteristic of Down syndrome) that predisposes this population to moyamoya disease.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">The disease can be more difficult to detect in children with Down syndrome than typical children, which may explain why, on average, children with Down syndrome are diagnosed with moyamoya disease nearly two years later than typical children. According to a 2015 study by researchers at Boston Children\u2019s Hospital, children with Down syndrome are usually diagnosed at age 8.4 versus 6.5 for typical children.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">A delayed diagnosis can allow moyamoya disease to progress to a more advanced stage.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">Dellapina believes an early diagnosis likely would have made a significant difference for her daughter, who, she now believes, showed signs of TIAs as early as age 11. In 2016, Erin underwent pial synangiosis surgery \u2014 the typical treatment for moyamoya disease. The procedure involves surgeons creating new blood vessels to supply the brain. It\u2019s believed these new blood vessels can do the job better and have a lower risk of bursting than the collaterals. Once the new vessels are functional, patients both with and without Down syndrome enjoy a normal life expectancy, Dr. Steinberg says.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">\u201cThat is why it\u2019s so important to diagnose and treat promptly,\u201d he says.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">Unfortunately, strokes and TIAs had already significantly damaged Erin\u2019s brain by the time she had surgery, which did not succeed in ending the strokes and seizures. Now 19, she receives hospice care while Dellapina focuses on giving her the best quality of life possible.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">For 25-year-old Madie Ehlers of Wisconsin, treatment has, so far, been successful. Born with Down syndrome, she was diagnosed with moyamoya disease in late 2013 at age 20. Like Erin, Madie experienced fleeting stroke-like symptoms and was initially misdiagnosed. She has had three surgeries since spring 2014 \u2014 two on the left side of her brain and one on the right, and her symptoms have disappeared.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">Today, Madie is back to being active in her community. She is training to become a certified Zumba instructor and plans to marry her boyfriend next year.<\/p>\n<p style=\"color: #000; padding: 0px 35px;\">\u201cMadie hasn\u2019t had any symptoms since two weeks after her most recent surgery in October 2018,\u201d says Madie\u2019s mother, Mary Beth Freckmann. \u201cDr. Sacho [who performed the surgery] really believes this will give her a very long life.&#8221;<\/p>\n<hr>\n<p style=\"color: #000; padding: 0px 35px;\"><strong><em>Like this article?<\/em><\/strong> Join Global Down Syndrome Foundation\u2019s Membership program today to receive 4 issues of the quarterly award-winning publication, plus access to 4 seasonal educational Webinar Series, and eligibility to apply for Global\u2019s Employment and Educational Grants.<br \/>\nRegister today at <a href=\"http:\/\/downsyndromeworld.org\/membership\" target=\"_blank\" rel=\"noopener noreferrer\">downsyndromeworld.org<\/a>!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Maria Dellapina and her daughter, Erin Farragher From Down Syndrome WorldTM Issue 1 2019 This rare disease is significantly more common in children with Down syndrome.
