Sleep disorders of Whipple's disease of the brain

Objective:
To understand the effects of Whipple's disease (WD) of the brain on sleep function.
Methods:
Clinical and polysomnographic studies of two patients with severe disruption of sleep due to WD: a 48-year-old female with primary WD of the brain and a 41-year-old male with secondary WD of the brain.
Results:
The patient with primary WD had hypersomnolence with severe obstructive sleep apnoea, reduced sleep efficiency, frequent waking and sleep fragmentation. The patient with secondary WD was also hypersomnolent with oculomastictory myorhythmia. He was shown to have severe sleep initiation insomnia with poor sleep efficiency, severe obstructive sleep apnoea/hypopnoea and oculomasticatory myorhythmia at sleep-wake transitions.
Conclusion:
WD of the brain may affect sleep biology in its primary and secondary forms leading to hypersomnolence from obstructive sleep apnoea, sleep fragmentation, reduced sleep efficiency, sleep initiation insomnia and intrusive oculomasticatory myorhythmia.
