| Abstract [eng] |
Othello syndrome (delusional jealousy) is a clinically significant yet ambiguously defined phenomenon associated with an increased risk of intimate partner violence and suicidal behavior. Despite its clinical relevance, contemporary psychiatry still reflects terminological and diagnostic uncertainty, and the phenomenon is often treated not as an independent diagnosis but as a symptom occurring in various psychiatric and neurological disorders. The aim of this thesis is to examine the clinical diversity of Othello syndrome, identify its associated risks, and discuss prevention strategies. The objectives are: (1) to review the scientific literature and analyze the forms and etiological factors of Othello syndrome; (2) to evaluate its impact on the individual and society; and (3) to discuss prevention strategies from a transdiagnostic perspective. A narrative literature review was conducted, including historical and contemporary sources from the nineteenth century to 2026, with particular attention to PubMed publications from 2005 to 2026. The analysis suggests that pathological jealousy forms a continuum from non-psychotic forms, such as obsessive jealousy and overvalued ideas, to delusional jealousy, which is conceptually linked to Othello syndrome in this thesis. Othello syndrome most often appears in the context of psychiatric, neurological, or substance-use disorders and is associated with serious consequences, including intimate partner violence, heteroaggression, and increased suicide risk. The conclusions emphasize that Othello syndrome should be understood as a heterogeneous clinical phenomenon rather than a single nosological category. Prevention and clinical management should follow a transdiagnostic and etiologically oriented approach, including early recognition of pathological or delusional jealousy, assessment of violence and suicide risk, safety planning, psychoeducation, psychotherapeutic interventions, treatment of substance use disorders, identification of organic or medication-related causes, and pharmacotherapy when clinically indicated. Early individualized intervention may reduce harm to the patient, partner, and family. Further research is needed, especially in the Lithuanian context. |
