Differences in the presentations of ADHD between boys and girls have been well established. Three subtypes of ADHD exist. In addition to sex difference, different mechanisms may underlie different subtypes. The present study enrolled 30 girls with the inattentive subtype of ADHD and 30 age-matched controls. Low-resolution electromagnetic tomography (LORETA) and instantaneous frequency were used to analyze electroencephalography (EEG) for investigating the brain area and EEG bands involved in girls with inattentive ADHD. We found that the instantaneous frequencies in all EEG channels in girls with ADHD were lower than those in controls. Alpha 2 was the only EEG band that showed significant difference in current density between the ADHD and control groups ( P = .0014). In the entire brain area, the posterior cingulate cortex, cingulate gyrus, and precuneus demonstrated the most significant difference between the ADHD and control groups. Our results suggest that brain maturation delay in the posterior areas might result in the inattention subtype of ADHD. In addition, posterior cingulate cortex, cingulate gyrus, and precuneus may play a critical role in the pathogenesis of ADHD. Our study provides a new approach method and possible mechanism of girls with inattentive subtype ADHD.<\/jats:p>","DOI":"10.1177\/1550059419899328","type":"journal-article","created":{"date-parts":[[2020,1,14]],"date-time":"2020-01-14T06:47:11Z","timestamp":1578984431000},"page":"325-330","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Delay Maturation in Occipital Lobe in Girls With Inattention Subtype of Attention-Deficit Hyperactivity Disorder"],"prefix":"10.1177","volume":"51","author":[{"given":"Tung-Ming","family":"Chang","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Changhua Christian Hospital, Changhua"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rei-Cheng","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Kaohsiung Medical University Hospital, Kaohsiung Medical University, Kaohsiung"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ching-Tai","family":"Chiang","sequence":"additional","affiliation":[{"name":"Department of Computer and Communication, National Pingtung University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen-Sen","family":"Ouyang","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, I-Shou University, Kaohsiung"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rong-Ching","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, I-Shou University, Kaohsiung"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2955-458X","authenticated-orcid":false,"given":"Sebastian","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Kaohsiung Medical University Hospital, Kaohsiung Medical University, Kaohsiung"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6963-1925","authenticated-orcid":false,"given":"Lung-Chang","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Kaohsiung Medical University Hospital, Kaohsiung Medical University, Kaohsiung"},{"name":"Department of Pediatrics, School of Medicine, College of Medicine, Kaohsiung Medical University, Kaohsiung"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,1,14]]},"reference":[{"key":"bibr1-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1007\/BF01670101"},{"key":"bibr2-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7610.1990.tb01565.x"},{"key":"bibr3-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1016\/j.pedn.2008.01.003"},{"key":"bibr4-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1007\/s13311-012-0135-8"},{"key":"bibr5-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1097\/00004583-199708000-00011"},{"key":"bibr6-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1002\/jclp.20121"},{"key":"bibr7-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1038\/s41390-018-0200-z"},{"key":"bibr8-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1016\/j.neubiorev.2016.11.002"},{"key":"bibr9-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1038\/mp.2014.183"},{"key":"bibr10-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/7526592"},{"key":"bibr11-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1016\/j.cytogfr.2016.11.003"},{"key":"bibr12-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1007\/s10578-015-0578-3"},{"key":"bibr13-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1016\/0167-8760(84)90014-X"},{"key":"bibr14-1550059419899328","first-page":"91","volume":"24","author":"Pascual-Marqui RD","year":"2002","journal-title":"Methods Find Exp Clin Pharmacol"},{"key":"bibr15-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1007\/s11517-015-1315-6"},{"key":"bibr16-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1016\/j.nicl.2017.09.011"},{"key":"bibr17-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1111\/jsr.12403"},{"key":"bibr18-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1007\/s10484-018-9420-6"},{"key":"bibr19-1550059419899328","first-page":"80","volume":"6","author":"Fair DA","year":"2012","journal-title":"Front Syst Neurosci"},{"key":"bibr20-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2004.12.007"},{"key":"bibr21-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1097\/01.wnp.0000221363.12503.78"},{"key":"bibr22-1550059419899328","doi-asserted-by":"publisher","DOI":"10.1142\/S0129065718500600"},{"key":"bibr23-1550059419899328","unstructured":"Pascual-Marqui RD.
