Creatine monohydrate is a nutritional supplement that has long been used by bodybuilders and athletes for performance enhancement and is something I've been considering for a while as a possible intervention for PWS because it not only improves muscle function but also brain function. Creatine plays an important role in mitochondrial function, so the recent revelations about mitochondrial impairment in PWS have moved it towards the top of my research priority list. There have been some small trials of its use for mitochondrial disorders that present with encephalopathy and myopathy such as Kearns-Sayre syndrome and MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes), with some reporting benefit and some finding no benefit.

The BBC has an August 2003 article about creatine for general readership - Creatine 'boosts brain power' http://news.bbc.co.uk/2/hi/health/3145223.stm

Here is an excellent, more detailed article for general readership - http://www.scq.ubc.ca/?p=194

As the BBC article notes, there are reports of creatine supplementation affecting blood sugar levels and it also may have effects on kidney function. Those issues need further investigation before any suggestions about its possible use for PWS can be made. However, I would be very interested to know if anyone has tried it or has heard of its use for PWS. Also, creatine, creatinine and/or creatine kinase (CK aka phosphocreatine kinase or creatine phosphokinase) levels are often checked for such things as evaluating muscle and renal function, so I would be interested if anyone happens to have lab results for those. (Mandy, I think the muscle enzyme test will probably include CK.) Finally, there was concern at one point while my friend's baby was in the NICU about her renal function. That apparently is no longer a problem, but in terms of evaluating creatine's appropriateness for PWS, I'm interested in whether renal function has been an issue for others with PWS.

Anecdote

Well, we started Kian on creatine on Monday. I just gave him a quarter of a scoop (1/4 teaspoon?) in the AM. He seems to tolerate it well.

On Sunday (pre-creatine) we were practicing jumping and he was awkwardly jumping over backpacks. Kian can jump adequately, but he doesn’t normally choose to jump.

On Monday in PM, he spontaneously jumped higher and farther than I have ever seen him jump. It was quite odd and my husband and I both stopped our conversation with dropped jaws to have him jump again.

Tuesday nothing really, but he did well at gymnastics.

Wednesday (today), I spent most of the day with him. We had a picnic in the park and we were waiting to cross the street. He spontaneously jumped up and down over and over because he was impatient. I have never seen him do that before. Then, he had his best day at yoga ever and was pretty good at doing the tree pose. From there we went to gymnastics and he was really good at gymnastics. Then he had a temper tantrum and jumped up and down again like Rumplestiltskin. Then later in the evening he spontaneously launched himself off of the bottom step jumping with two feet and landing very steadily. He has never done that before.

He does not appear to be eating more food, but he does seem to be drinking a lot more water.

Now, about the temper tantrum. I think it was related to low blood sugar. He and I were having a good time and he really didn’t want to eat much. He had a small yogurt for lunch (trying to repopulate his gut after antibiotics) and that was it. He turned down all other food and played in the park and did yoga and did gymnastics and then melted down. The only way I could calm him down was to feed him. He refused food, but I basically forced/tricked him to eat almond butter with a bit of honey. That calmed him down and he was perfectly fine the rest of the day.

So, who knows… These changes are subtle, but I guess that I wouldn’t expect more than subtle changes at this point in his development. One other thing is that he is talking like crazy and seems to have more fluency. He is still working on articulation, however.

For the record. I have noticed great changes with CoQ10 (when Kian was 2 months old), carnitine fumarate (started at 2 ½), and now creatine (Kian is almost 4). Kian also gets omega 3’s, B vitamins, and a multivitamin. I believe that these help him, but I did not notice anything dramatic when I introduced them to his diet.
