Sensory perception of patients with sleep disorders
Background and Aim : It is well known that patients with sleep debt may have sensory deficit and complain of sensory troubles, however, little literature has been devoted to sensory perception of patients with sleep disorders. The aim of this paper is to explore sensory perception profile of sleep disorder patients.
Methods : Sleep of patients and controls was systematically recorded during an one-night polysomnography. Sleep disorders diagnosis were based on the ICSD2d classification. 41 patients aged from 21 to 75 years-old and 20 controls aged from 21 to 40 years-old have been interviewed and the “Visual/audio/kinesthesis” 25 items scale applied, this scale can quantify the proportion of vision, audition or kinesthesia is used for learning by each individual, based on the number of points given to each perception type.
Results : The groups were divided into 4: Sleep apnea, Insomnia, Hypersomnia and Controls, all of them had a visual preference. Sleep patients (16 with sleep apnea, 15 with insomnia, 6 with hypersomnia and 3 with narcolepsy) were compared with controls and their perceptual profile wasn’t statically different; the average visual score was of 10.2 vs 9.6 (p=0,38); audio score of 7.6 vs 7.8 (p=0,78) and kinesthesis score of 7.2 vs 7.6 (p=0,56). When making comparisons in between each category of the sleep disorder including controls there were also no significate difference in the visual score (p=0,9); audio score (p=0,6) and kinesthesis score (p=0,76)
Conclusion : Our study showed no difference in the perception profile of patients with sleep disturbances
compared with controls. However, the scale used consisted of a subjective evaluation made by the patient and the number of patients included were too small; So, more studies need to be performed to better explore their perception, which may help clinicians in taking better care of their patients with sleep disabilities and poor quality of life.
Key-Words : Sleep disorders, sleep debt, perceptual learning.
