Hello Indie'sOK, and welcome to NeuroTalk.
I really don't know anything about that condition, but I looked it up and see that it can be associated with the following:
Hypokalemic sensory over stimulation
I dare say there are other causes, but those were the ones I found and with them in mind, you can either post under :
General Health Conditions : http://neurotalk.psychcentral.com/forum2.html
Our Autism sub-forum: http://neurotalk.psychcentral.com/forum8.html
General Mental Health : http://neurotalk.psychcentral.com/forum85.html
or if you feel your diet or medications may be the cause, then maybe under Vitamins, Nutrients, Herbs and Supplements :
I hope some-one comes along you who knows more about the condition than I do.
