Abstract
Modifications of brain activity in the early stages of Parkinson's disease (PD) are difficult to detect using electroencephalography (EEG) signals and are often biased by L-DOPA treatment. We compare here the performances of both linear and non-linear methods in differentiating EEG of L-DOPA naive PD patients from that of control subjects.

The following measurements were computed: theta-, alpha- and beta-band relative powers constituted the linear indices; localized entropy, slope asymmetry and number of non-linear EEG segments constituted the non-linear indices.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">In the case of linear quantification, only a decrease in the beta-band was observed for patients. Significant non-linear structures were observed in our EEG data. Non-linear quantifiers demonstrate an increase in entropy and in the number of non-linear EEG segments for the patients.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">Changes in EEG dynamics observed here in L-DOPA naive PD patients may represent early signs of cortical dysfunction produced by subcortical dopamine depletion.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Pezard</LastName><ForeName>L</ForeName><Initials>L</Initials><AffiliationInfo><Affiliation>Laboratoire de Neurosciences Comportementales, Université René Descartes, 45 rue des Saints-Pères, F-75270 Cedex 06, Paris, France.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Jech</LastName><ForeName>R</ForeName><Initials>R</Initials></Author><Author ValidYN="Y"><LastName>Růzicka</LastName><ForeName>E</ForeName><Initials>E</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016430">Clinical Trial</PublicationType><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>Netherlands</Country><MedlineTA>Clin Neurophysiol</MedlineTA><NlmUniqueID>100883319</NlmUniqueID><ISSNLinking>1388-2457</ISSNLinking></MedlineJournalInfo><ChemicalList><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D000978">Antiparkinson Agents</NameOfSubstance></Chemical></ChemicalList><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName UI="D000465" MajorTopicYN="N">Algorithms</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D000978" MajorTopicYN="N">Antiparkinson Agents</DescriptorName><QualifierName UI="Q000627" MajorTopicYN="N">therapeutic use</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D004569" MajorTopicYN="Y">Electroencephalography</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D019277" MajorTopicYN="N">Entropy</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D005260" MajorTopicYN="N">Female</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D006801" MajorTopicYN="N">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D008297" MajorTopicYN="N">Male</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D008875" MajorTopicYN="N">Middle Aged</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D017711" MajorTopicYN="N">Nonlinear Dynamics</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D010300" MajorTopicYN="N">Parkinson Disease</DescriptorName><QualifierName UI="Q000188" MajorTopicYN="N">drug therapy</QualifierName><QualifierName UI="Q000503" MajorTopicYN="Y">physiopathology</QualifierName><QualifierName UI="Q000523" MajorTopicYN="N">psychology</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D011569" MajorTopicYN="N">Psychiatric Status Rating Scales</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="pubmed"><Year>2001</Year><Month>1</Month><Day>4</Day><Hour>11</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2001</Year><Month>3</Month><Day>3</Day><Hour>10</Hour><Minute>1</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2001</Year><Month>1</Month><Day>4</Day><Hour>11</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">11137659</ArticleId><ArticleId IdType="pii">S1388-2457(00)00512-5</ArticleId></ArticleIdList></PubmedData></pubmed><affiliations><list><country><li>France</li></country><region><li>Île-de-France</li></region><settlement><li>Paris</li></settlement></list><tree><noCountry><name sortKey="Jech, R" sort="Jech, R" uniqKey="Jech R" first="R" last="Jech">R.
