In fibromyalgia, normal sleep patterns are disrupted and sleep is of very poor quality: light, choppy, and lacking the normal periods of “delta wave” or deep sleep (Moldofsky 2008). Studies consistently show that patients with fibromyalgia don’t spend much time in deep sleep, and the deep sleep they do get is interrupted by fast “wakeful” brain waves (alpha waves) that are normally only seen in the awake brain, a phenomenon called “alpha-wave intrusion”
