We aimed to identify the electroencephalographic (EEG) power spectrum associated with the performance of the Raven as a reasoning\/problem-solving task among individuals with recent suicide attempts.\n                    <jats:italic>Methods<\/jats:italic>\n                    : This study with the case-control method, consisted of 61 participants who were assigned to three groups: Suicide attempt\u2009+\u2009Major Depressive Disorder (SA\u2009+\u2009MDD), Major Depressive Disorder (MDD), and Healthy Control (HC). All participants underwent clinical evaluations and problem-solving abilities. Subsequently, EEG signals were recorded while performing the Raven task.\n                    <jats:italic>Results<\/jats:italic>\n                    : The SA\u2009+\u2009MDD and MDD groups were significantly different from the HC group in terms of anxiety, reasons for life, and hopelessness. Regarding brain oscillations in performing the raven task, increased theta, gamma, and betha power extending over the frontal areas, including anterior prefrontal cortex, dlPFC, pre-SMA, inferior frontal cortex, and medial prefrontal cortex, was significant in SA\u2009+\u2009MDD compared with other groups. The alpha wave was more prominent in the left frontal, particularly in dlPFC in SA\u2009+\u2009MDD. Compared to the MDD group, the SA\u2009+\u2009MDD group had a shorter reaction time, while their response accuracy did not differ significantly.\n                    <jats:italic>Conclusions<\/jats:italic>\n                    : Suicidal patients have more frontal activity in planning and executive function than the two other groups. Nevertheless, it seems that reduced activity in the left frontal region, which plays a crucial role in managing emotional distress, can contribute to suicidal tendencies among vulnerable individuals.\n                    <jats:italic>Limitation<\/jats:italic>\n                    The small sample size and chosen difficult trials for the Raven task were the most limitations of the study.\n                  <\/jats:p>","DOI":"10.1177\/15500594241273125","type":"journal-article","created":{"date-parts":[[2024,8,28]],"date-time":"2024-08-28T10:08:24Z","timestamp":1724839704000},"page":"140-149","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Frontal Activity of Recent Suicide Attempters: EEG spectrum Power Performing Raven Task"],"prefix":"10.1177","volume":"56","author":[{"given":"Nafee","family":"Rasouli","sequence":"first","affiliation":[{"name":"Department of Clinical Psychology, School of Behavioral Sciences and Mental Health, Iran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8148-5422","authenticated-orcid":false,"given":"Seyed Kazem","family":"Malakouti","sequence":"additional","affiliation":[{"name":"Geriatric Mental Health Research Center, School of Behavioral Sciences and Mental Health, Iran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0013-4450","authenticated-orcid":false,"given":"Masoumeh","family":"Bayat","sequence":"additional","affiliation":[{"name":"Geriatric Mental Health Research Center, School of Behavioral Sciences and Mental Health, Iran University of Medical Sciences, Tehran, Iran"},{"name":"Gerontology Department, School of Behavioral Sciences and Mental Health, Iran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Firouzeh","family":"Mahjoubnavaz","sequence":"additional","affiliation":[{"name":"Institute for Cognitive and Brain Sciences, Shahid Beheshti University, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niloofar","family":"Fallahinia","sequence":"additional","affiliation":[{"name":"Mental Health Research Center, Iran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6282-9389","authenticated-orcid":false,"given":"Reza","family":"Khosrowabadi","sequence":"additional","affiliation":[{"name":"Institute for Cognitive and Brain Sciences, Shahid Beheshti University, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,8,28]]},"reference":[{"issue":"1","key":"e_1_3_3_2_2","first-page":"73","article-title":"Suicide in Iran: The facts and the figures from nationwide reports","volume":"12","author":"Hassanian-Moghaddam H","year":"2017","unstructured":"Hassanian-Moghaddam H, Zamani N.
