Abstract
For essential tremor, the distribution of age of onset is bimodally distributed, with peaks in adolescence and another in late adulthood. The latter is here referred to as aging-related tremor, and it is considered to be associated with earlier aging and increased mortality. We hypothesize that different tremor networks detected by multichannel electroencephalography (EEG) underlie these two tremor groups.

Functional and effective connectivity at the coupling frequency was estimated.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">The maximal coherence was significantly higher in early-onset essential tremor compared with aging-related tremor during the three tasks. Compared with the patients with aging-related tremor, 2 Hz to 40 Hz power, spectral peak frequency, and relative signal-to-noise ratio were not different, but the electromyographic amplitude was significantly greater in essential tremor. The source analysis revealed the well-known cortico-brainstem-cerebello-thalamo-cortical network for classical essential tremor, but patients with aging-related tremor showed a cortico-thalamic network only. The connections between the sources for both tremors were bidirectional. Only the cerebellum and the brainstem showed unidirectional connections in essential tremor and the thalamus in aging-related tremor patients. A second essential tremor group with similar electromyographic amplitudes confirmed the differences between both tremor types.</AbstractText><AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">We show that the oscillating cerebral networks underlying classical essential tremor and aging-related tremor differ, suggesting a pathophysiological difference. © 2015 International Parkinson and Movement Disorder Society.</AbstractText><CopyrightInformation>© 2015 International Parkinson and Movement Disorder Society.</CopyrightInformation></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Muthuraman</LastName><ForeName>Muthuraman</ForeName><Initials>M</Initials><AffiliationInfo><Affiliation>Department of Neurology, University Hospital Schleswig Holstein, Campus Kiel, Germany.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Deuschl</LastName><ForeName>Günther</ForeName><Initials>G</Initials><AffiliationInfo><Affiliation>Department of Neurology, University Hospital Schleswig Holstein, Campus Kiel, Germany.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Anwar</LastName><ForeName>Abdul Rauf</ForeName><Initials>AR</Initials><AffiliationInfo><Affiliation>Department of Neurology, University Hospital Schleswig Holstein, Campus Kiel, Germany.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Mideksa</LastName><ForeName>Kidist Gebremariam</ForeName><Initials>KG</Initials><AffiliationInfo><Affiliation>Department of Neurology, University Hospital Schleswig Holstein, Campus Kiel, Germany.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>von Helmolt</LastName><ForeName>Friederike</ForeName><Initials>F</Initials><AffiliationInfo><Affiliation>Department of Neurology, University Hospital Schleswig Holstein, Campus Kiel, Germany.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Schneider</LastName><ForeName>Susanne A</ForeName><Initials>SA</Initials><AffiliationInfo><Affiliation>Department of Neurology, University Hospital Schleswig Holstein, Campus Kiel, Germany.</Affiliation></AffiliationInfo></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType></PublicationTypeList><ArticleDate DateType="Electronic"><Year>2015</Year><Month>09</Month><Day>08</Day></ArticleDate></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>Mov Disord</MedlineTA><NlmUniqueID>8610688</NlmUniqueID><ISSNLinking>0885-3185</ISSNLinking></MedlineJournalInfo><CitationSubset>IM</CitationSubset><KeywordList Owner="NOTNLM"><Keyword MajorTopicYN="N">Essential tremor</Keyword><Keyword MajorTopicYN="N">aging-related tremor</Keyword><Keyword MajorTopicYN="N">brain stem</Keyword><Keyword MajorTopicYN="N">cerebellum</Keyword><Keyword MajorTopicYN="N">coherence</Keyword><Keyword MajorTopicYN="N">connectivity</Keyword><Keyword MajorTopicYN="N">source analysis</Keyword></KeywordList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="received"><Year>2015</Year><Month>4</Month><Day>1</Day></PubMedPubDate><PubMedPubDate PubStatus="revised"><Year>2015</Year><Month>7</Month><Day>13</Day></PubMedPubDate><PubMedPubDate PubStatus="accepted"><Year>2015</Year><Month>7</Month><Day>31</Day></PubMedPubDate><PubMedPubDate PubStatus="aheadofprint"><Year>2015</Year><Month>9</Month><Day>8</Day></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2015</Year><Month>9</Month><Day>9</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2015</Year><Month>9</Month><Day>9</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2015</Year><Month>9</Month><Day>9</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">26347194</ArticleId><ArticleId IdType="doi">10.1002/mds.26410</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
