| pubmed-article:1326181 | pubmed:abstractText | The authors demonstrate the high prevalence of snoring among patients with different patterns of neurological pathology. It is very essential since snoring is a marker of apnea in sleep (AS). A nocturnal polygraphy study was carried out in 55 patients with AS. In central and mixed apnea, the structure of the sleep was found to be relatively intact whereas in obstructive apnea, the sleep was grossly disordered. In obstructive AS, the index of apnea was higher in the slow sleep phase, in central AS, in the fast sleep phase. | lld:pubmed |
