Human Growth Hormone for Adults with PWS

This article is adapted from a presentation by Jennifer Miller, Ph.D.

Decreased Cardiovascular Risk

Growth hormone deficiency has been shown to increase cardiovascular risk, especially in adultsGrowth hormone therapy in adults increases the cardiac mass, while it decreases the size of the left heart ventricle of the PWS patient. Both of these result in an improved heart metabolism, and in an overall decreased cardiovascular risk.

Cognitive Benefits

Cognitive benefits of human growth hormone for PWS are evidenced in adults as well as children. Adults with PWS treated with human growth hormone show improvement in mental speed, flexibility and motor performance.

When going through growth hormone stimulation tests, adult patients are taken off from their regular dosing for a month. (See this blog for more information on human growth hormone dosing for PWS.) The goal of the stimulation test is to measure the natural ability of the body to produce growth hormone.

When the test is done, patients seem to be partially impaired in both physical and social skills. When they're put back in growth hormone therapy, there's notorious improvement in self-control, vitality and in an overall quality of lifeSome patients have expressed that when resuming human growth hormone treatment, they just feel better, they feel normal again.

Those who are in HGH therapy usually show an increase of around 10% of white matter over the course of a year. In one case, an adult who started growth hormone therapy had to be taken off for a year during recovery; this is a much longer period of time off than in stimulation tests. After this period a posterior MRI test showed that his brain white matter had decreased 20%

There is an increased atrophy in brains of adults with PWS who are non-growth-hormone treated, which might lead to degenerative diseases of the brain, including the risk of Alzheimer's.

Overall, human growth hormone for adults with PWS is an undeniably beneficial treatment which provides numerous benefits and an improved quality of life.

Susan Hedstrom is the Executive Director for the Foundation for Prader-Willi Research. Passionate about finding treatments for PWS, Susan joined FPWR in 2009 shortly after her son, Jayden, was diagnosed with Prader-Willi Syndrome. Rather than accepting PWS as it has been defined, Susan has chosen to work with a team of pro-active and tireless individuals to accelerate PWS research in order to change the natural history of PWS. Inspired by her first FPWR conference and the team of researchers that were working to find answers for the syndrome, she hosted her first One SMALL Step walk in 2010 and began the development of the One SMALL Step walk program which now raises over $1.5 million a year for PWS research.
