Hi! I'm doing a project at college on CFS/ME as I'm very interested in finding out more due to my mum having the illness. I was wondering if there are any possible causes that would be helpful for me to look at? I'm trying to understand more about what might cause the illness and the link with stress. I have so far come accross the XMRV link, HPA axis dysfunction and mitochondrial dysfunction. I was also going to look into possible gene markers for CFS/ME so any information on these would be a great help! Thank you!
