Pathological sleepiness (i.e. mean sleep latency \u22645\u2003min) was common (40 of 134 nap opportunities), and sleep\u2010onset REM periods were also observed (13 of 134 nap opportunities). These findings bore little relationship to disease specific variables (e.g. level of disability, medication use), or sleep architecture measures (e.g. total sleep time, sleep stage percentage\u2019s). Our findings speak against a simple association of excessive sleepiness and the quality and quantity of prior night\u2019s sleep, but rather, argue for primary impairments of waking arousal and REM\u2010sleep expression in a sizeable subpopulation of PD patients.<\/jats:p>","DOI":"10.1046\/j.1365-2869.2000.00201.x","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T08:59:23Z","timestamp":1047459563000},"page":"63-69","source":"Crossref","is-referenced-by-count":203,"title":["Daytime sleepiness in Parkinson\u2019s disease"],"prefix":"10.1111","volume":"9","author":[{"given":"David B.","family":"Rye","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donald L.","family":"Bliwise","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bhupesh","family":"Dihenia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Gurecki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2001,12,24]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/15.2.173"},{"key":"e_1_2_6_3_1","first-page":"749","article-title":"Recording and scoring leg movements","volume":"16","author":"American Sleep Disorders Association Atlas Task Force","year":"1993","journal-title":"Sleep"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/9.1.232"},{"key":"e_1_2_6_5_1","first-page":"342","article-title":"Mean versus median for the multiple sleep latency test","volume":"18","author":"Benbadis S.
