Ask Nurse Lynn: PWS and Aging

Question:

Female, 65 years old, Deletion subtype

My sister lives with caregivers in Alberta. She turned 65 this year, and over the last few years she has developed a number of health issues. Due to balance issues, she has been using a walker for the last couple of years. It is hard to find any information on PW and aging and was interested when I came across the PWSA blog. In the section on accelerated biological aging, the writer refers to mUPD. What is it?
And can you refer me to any other information regarding PW and aging. Thank you.

Nurse Lynn’s Response:

As people with PWS get older, doctors and families are learning more about how the body changes with age. Some people may show signs of “early aging,” like losing muscle strength, getting tired more easily, or having more balance problems. This may happen because the part of the brain that controls hormones (the hypothalamus) doesn’t work the same way in PWS. That can cause lower hormone levels and changes in muscle and bone over time.

Inside our cells, the tiny “power houses” called mitochondria can also slow down, making less energy and creating more “waste,” which can damage cells little by little. People with PWS may also have changes in how their genes are turned on or off (called epigenetics), and that may make their bodies age a bit faster.

You may have read the term mUPD — it stands for maternal uniparental disomy. That means both copies of chromosome 15 come from the mother instead of one from each parent. This is one type of PWS and can sometimes be linked to more mood or thinking changes with age.

While research is still new, studies show that staying active, getting enough sleep, eating healthy foods, and having hormones like growth hormone checked regularly can help support healthier aging in PWS.
