As it responds poorly to levodopa and is associated with reduced midbrain and pons volume, it may result from non\u2010dopaminergic, brainstem lesions. As several sleep abnormalities in PD also result from non\u2010dopaminergic brainstem lesions, we monitored sleep in 24 non\u2010demented PD patients with (n = 12) and without (n = 12) camptocormia and in 12 controls. Nearly half (42%) patients with camptocormia had abnormal periodic leg movement indices (&gt;15\/h), versus 17% patients without camptocormia and 8% of controls (<jats:italic>p<\/jats:italic> = 0.02). In addition, the percentage of enhanced muscle activity during REM sleep (measured on the chin and on the limb muscles) tended to be higher in patients with than without camptocormia (51 \u00b1 39% vs. 20 \u00b1 25%, <jats:italic>p<\/jats:italic> = 0.06). The other sleep and REM sleep characteristics (sleep and REM sleep onset latencies, sleep time and sleep stage percentages, REMs density, arousal, and apnea\u2010hypopnea indices) were not different between these two PD groups. Lesions causing this axial dystonia may spare the sleep systems but affect the control of movements during sleep. \u00a9 2009 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.22854","type":"journal-article","created":{"date-parts":[[2009,11,4]],"date-time":"2009-11-04T16:39:30Z","timestamp":1257352770000},"page":"2419-2423","source":"Crossref","is-referenced-by-count":14,"title":["Periodic leg movements and REM sleep without atonia in Parkinson's disease with camptocormia"],"prefix":"10.1002","volume":"24","author":[{"given":"Sophie","family":"Lavault","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederic","family":"Bloch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean\u2010Luc","family":"Houeto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Konofal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie\u2010Laure","family":"Welter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yves","family":"Agid","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabelle","family":"Arnulf","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,12,18]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1155\/2004\/163957"},{"key":"e_1_2_7_3_2","first-page":"481","article-title":"La camptocormie primitive est une myopathie para\u2010vertebrale","volume":"61","author":"Laroche M","year":"1994","journal-title":"Rev Rhum"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2008.150011"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2006.087908"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-008-0927-8"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awm056"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroscience.2008.03.085"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1997.00550200007003"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3956(75)90026-6"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/14.6.540"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.17.5.427"},{"key":"e_1_2_7_13_2","first-page":"349","article-title":"REM sleep behavior disorder and REM sleep without atonia in patients with progressive supranuclear palsy","volume":"28","author":"Arnulf I","year":"2005","journal-title":"Sleep"},{"key":"e_1_2_7_14_2","unstructured":"American Academy of Sleep Medicine.
