We usually think of allied disorders as being fibromyalgia, TMJ, IBS, GWS but what about disorders that suggest 'seizure' or CNS overactivation such as epilepsy. Does that fit in with CFS? Perhaps...they didn't look for CFS but they did look for FM and they found it. People with epilepsy were more likely to report they had been diagnosed with a wide variety of disorders including FM, chronic pain, migraine, ADHD, anxiety, depression, asthma (asthma?). Of course the depression and anxiety are probably expected to be higher than normal because they had a chronic illness but the ADHD, FM, migraine are interesting since all of these may be increased in CFS as well.
