Liam & Ataxia Telangiectasia



Liam Cowand
May 7, 2001 - February 26, 2021

When Liam was 4 years old he was diagnosed w a rare genetic neurodegenerative disease called Ataxia Telangiectasia (tel-an-JICK-tay-sha), or A-T for short. A-T is a recessive disease, which means both my husband & I are carriers. Together we had a 1 in 4 chance of having an A-T kid. Liam is our 2nd born of 4. This means that our other 3 kids could either be carriers like my husband & I are, each carrying one gene of A-T, or they could be completely A-T free. The only way to know for sure is genetic testing, which is expensive & as it is not considered necessary is not covered by insurance.


WHAT IS A-T?
A Multi-system Disease... Ataxia-telangiectasia, or "A-T," is a progressive, degenerative disease that affects a startling variety of body systems. The first signs of the disease usually appear early in childhood (the toddler stage), when children begin to walk. Though they usually start walking at a normal age, they wobble or sway when walking, standing still or sitting. In late pre-school and early school age, children with A-T develop difficulty moving the eyes in a natural manner from one place to the next, and they develop slurred or distorted speech, and swallowing problems.

Ataxia...
The onset of this ataxia marks the beginning of progressive degeneration of a part of the brain, known as the cerebellum, that gradually leads to a general lack of muscle control, and eventually confines the patient to a wheelchair. Because of the worsening ataxia, children with A-T lose their ability to write, and speech also becomes slowed and slurred. Even reading eventually becomes impossible as eye movements become difficult to control.

Telangiectasia...
Soon after the onset of the ataxia, the A-T patient usually shows another clinical hallmark of A-T: "telangiectasia," or tiny red "spider" veins which appear in the corners of the eyes or on the surface of the ears and cheeks exposed to sunlight. Although these telangiectasia are seemingly harmless, their unique appearance together with ataxia is what led to naming this disease "ataxia-telangiectasia."
Immune System Problems...

For most (about 70 percent) of children with A-T there is another clinical hallmark: immunodeficiency that usually brings recurrent respiratory infections. In many patients, these infections can become life threatening. Because of deficient levels of immunoglobulins (IgG, IgA, IgM or IgG subclasses), the natural infection fighting agents in the blood, children with A-T are highly susceptible to lung infections that do not respond to typical antibiotic treatments. For these A-T patients, the combination of a weakened immune system and the progressive ataxia can ultimately lead to pneumonia as a common cause of death.

Predisposition to Cancer...
Children with A-T tend to develop malignancies of the blood system almost 1,000 times more frequently than the general population. Lymphoma and leukemia are particularly common types of cancer, although the frequencies of most cancers are elevated. Ironically, another facet of the disease is an extreme sensitivity to radiation, which means that A-T patients cannot tolerate the standard levels of therapeutic radiation or radiomimetic drugs (chemotherapy drugs that work in a way that is similar to radiation therapy) usually given to cancer patients.

Other Features of A-T...
Other features of ataxia-telangiectasia that may affect some children are:diabetes mellitus, premature graying of the hair, difficulty swallowing causing choking and/or drooling and slowed growth. Even though A-T is a multi-system disorder, most individuals with A-T are very socially aware and socially skilled.

How Frequent is A-T?
Ataxia-telangiectasia respects no racial, economic, geographic or education barriers. Both males and females are equally affected. Epidemiologists estimate the frequency of A-T between 1 in 40,000 and 1 in 100,000 births. But it is believed that many children with A-T, particularly those who die at a young age, are never properly diagnosed. Therefore, this disease may actually be much more common.
Prognosis...

A-T is presently incurable and unrelenting. If they are lucky enough not to develop cancer, most A-T children are dependent on wheelchairs by the age of ten, not because their muscles are too weak, but because they cannot control them. Later, A-T patients usually die from respiratory failure or cancer by their early or mid-twenties. A few A-T patients live into their forties, but they are extremely rare.
What treatments are available?

There is no cure for A-T, and there is currently no way to slow the progression of the disease. At this time, treatments are directed only toward partially alleviating some symptoms as they appear. Because A-T is a rare, "orphan" disease, very little research data is available on pharmaceutical therapies that may aid these children. Physical, occupational and speech therapy are used to help maintain flexibility, gamma-globulin injections help supplement the immune systems of A-T patients, and high-dose vitamin regimes are being undertaken with some moderate results.



All of the above came from the webpage from the A-T Children's Project. A non-profit organization created by a husband & wife, after 2 of their 3 sons were diagnosed with A-T.

Liam passed away at 19. He was wheelchair-bound from the age of 7. He had Primary Immundeficient Disease, Reactive Airway Disease, as well as symptoms similar to Cystic Fibrosis, and more recently diagnosed with Myeloproliferative Disease. He was diagnosed as failure to thrive when he was 12 because he was too weak to chew & swallow enough food to sustain his growth. He then had a PEG tube surgically placed into his abdomen, once it healed enough, it was swapped out & replaced with a mini-one button, very similar to a Mic-Key button. He got 90% of his nutrition through his button. 4 bottles of Boost Plus were fed to him via the tube/a Joey Pump each day. This way he was able to save his energy for eating things he really wanted to eat and didn't have to worry about counting calories or looking for nutrient or calorie-dense food.

You can follow his story & life more closely on his Facebook page, Stubbornly Liam.

Or you can donate directly to the A-T Children's Project via their website.

Money isn't the only way you can help...you can sign up to be a volunteer in your area to help with the grassroots fundraising from local A-T families & get to know them in your area. There is a group on Facebook that will help you get in touch with local A-T families in your area. A-T Volunteer Squad. Any help you can give is appreciated greatly by our family & all the other A-T families like ours.

Vitale (1962) began in New York in 1951 when the New York Board of Regents of the Department of Education in the state of New York proposed that public schools should be authorized, not required, to start the day with a non-denominational prayer (Engel v. Vidal, n.d.). Superintendent William J. Vitale Jr., who oversaw Herricks Union Free School District in 1958 adopted the proposal ( Engel V. Vitale, 370 U.S. 421 (1962) , n.d.). Five Harrick’s parents, however, felt that having a prayer was against the Establishment Clause found in the First Amendment of the United States Constitution. In that clause, the First Amendment states, “Congress shall make no law res...

Letter to Liam

Hello, my darling boy.  I miss you so much. It's been a whirlwind of a year that found us constantly thinking about you and wishing you were with us in person rather than in spirit, to share in all the activities. 2 years ago today you left us. I know your little body was tired and, that made your soul tired as well.  But I'm a selfish mom, I'd rather have you here with me. I still sleep with your blanket and pillow every night. I don't honestly know if that will ever stop as I love having something you loved so much with me. I love holding it while I sleep and several times I have had vivid dreams of us together, although I prefer to think of them not as dreams but as you coming and visiting me while I sleep, because that way I get to actually see, hold, and talk to you again. Your birthday is just a couple of months away now, you'd be 22 this year.  There are so many things that I still can't do without you because it hurts too much. I still watch Doctor Who b...

1461 Days Without You

  Cliffs of Moher - County Clare, Ireland My sweet Liam,       Another year has passed. It's been 4 years now and it still feels like it was just yesterday you were here with us, laughing and hugging. I am now in your room, using it as my office/craft room. Every time I walk into it I feel you all around me. If you remember, I was supposed to have the basement office we constructed before/during COVID but I am so much happier in your room surrounded by memories of you than I would be in that office. When I am in here it still feels like it's the Liam and Mom Show. Best buddies, always together. I am just over the halfway point as I earn my degree in political sciences and already feel incredibly burned out, it doesn't help that Trump and the GOP are once again in office running this country into the ground. But good news, Dad and I are heading to Italy on Monday for 11 days, it's almost our wedding anniversary.  Thirty years on March 10th. Kier and Sam just cele...
