An excellent article on this subject:
lymemd.blogspot.com/2008/06/lyme-and-sleep.html"Sleep apnea is more common in Lyme patients in my experience. It is classically associated with obesity, snoring and fatigue. But these signs may be absent. Many Lyme patients have neurologic dysfunction of the palate and uvula which may contribute to this disorder.
In addition, brain abnormalities of Lyme may be a contributing factor. Sleep apnea is mostly peripheral, due to floppiness of the soft tissues in the back of the throat; but it may also be central, due to brain dysfunction.
Patients with sleep apnea have severe fatigue, a symptom commonly reported in Lyme disease. These patients also have cognitive difficulties which may be similar to those seen in Lyme.
Patients with sleep apnea have been shown to have abnormal SPECT scans with decreased blood flow to the frontal lobes of the brain. This is associated with poor executive function. This creates a syndrome which mimics attention deficit disorder, a finding which is also common in Lyme patients.
Patients who are chronically deprived of deep sleep called stage 4 sleep, associated with delta waves on the EEG, electroencephalograph, have been shown to develop diffuse muscle pain which resembles fibromyalgia, another common Lyme syndrome. "
