Special Issue Information

Dear Colleagues,

The expectation of defining a precise genetic marker that can identify bipolar disorder (BD) has been dashed by current research, as the psycho-pathology of severe mental illnesses, including BD, includes complex traits sustained by the coalescence of many genes, each of which exerts small influences on observable phenomena, thus hindering Mendelian randomization studies and the identification of reliable biomarkers of lithium response.

A broader view of the polygenic hypothesis has prompted current studies to look for conditions, possibly related to specific genetic characteristics, that might, in interaction with the environment, put BD at risk in interaction with the environment.

This Special Issue aims to gather contributions in the area of research we have thus defined. In particular, because of the preventive importance of being able to identify conditions at risk of developing bipolar disorder, this contribution aims to gather information on new genetic, laboratory, and more generally diagnostic techniques that may make it possible to identify the risk area, described by the above-mentioned new line of research, of future bipolar disorder.

Contributors are welcome to use the formats of an original research article, brief research report, systematic review, review, mini-review, policy and practice review, hypothesis and theory, perspective, case report, community case study, general commentary, or opinion.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Clinical Medicine is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Background: Children and adolescents with subthreshold manic symptoms not meeting full DSM criteria for bipolar I or II disorder (BP-I or BP-II) are classified as unspecified bipolar disorder (formerly bipolar not otherwise specified: BP-NOS). Factors associated with transition from BP-II or NOS to BP-I may predict the progression of the disorder. Our objective is to analyze factors associated with transition to BP-I in a Spanish sample of youth with BP-NOS or BP-II. Methods: We included all youth diagnosed with BP before 18 years of age presenting to our clinic (October 1999–December 2014). We assessed clinical factors that may predict transition to BP I with a logistic regression and a multivariable model for data analysis. Results: A total of 72 patients with BP, mean (SD) age 14.5 (10.5–16.0) years, were followed for a median period of 3.9 years. In total, 95.8% of patients retained the BP diagnosis, but they changed type. Baseline BP-I % was 37.5%, and 62.5% at endpoint. BP-NOS decreased from baseline 54.2% to 25% at endpoint. The % of BP-II was 8.3% in both time points, but they were not the same individual patients, as some transitioned from BP-II to BP-I and some BP-NOS changed to BP-II. BP-NOS was stable in 46.1% of patients, but 38.5% transitioned to BP-I over time. Psychotic symptoms during prior depressive episodes (MDD) increased the risk of transition to BP-I by 11-fold. Each individual symptom of mania increased the risk of transition to BP-I by 1.41. Conclusions: BP-NOS was stable in 46.1% of patients, but 38.5% transitioned to BP-I over time. Psychotic symptoms during prior MDD episodes increased the risk of transition from BP-NOS to BP-I. Full article
