[Sleep disturbance in chronic fatigue syndrome].
Attempts to elucidate the complex pathophysiology of chronic fatigue syndrome (CFS) must consider subjective and objective sleep. Several reports of CFS showed the high rate of sleep disturbance such as insomnia, hypersomnia, circadian rhythm sleep disorder, sleep apnea/hypopnea syndrome and so on. To analyze pulse wave continuously in sleep of CFS patients by laser blood flowmeter, we set base line component (0.01-0.08 Hz) and pulse wave component(0.70-1.50 Hz). Results of FFT analysis indicate that the CFS can have at least three subtypes of pulse dynamics in sleep. There probably are different types of illnesses now contained within the CFS construct, in which identifying subtypes of sleep disturbance can be one important key.
