Dangerous Intersection of Alcoholism and Othello Syndrome: A Comprehensive Review of Delusional Jealousy and Treatment Strategies.

The modern pace of life, increased susceptibility to stressors, and easy access to psychoactive substances have contributed to the increase in the number of people addicted to alcohol. Alcoholism has serious and life-threatening consequences, one of which is brain damage causing morbid jealousy, otherwise known as Othello syndrome. The disease, currently classified as a subtype of delusional disorder, manifests itself in groundless and dangerous judgments about a partner's sexual infidelity. People with Othello syndrome constantly believe in their partner's infidelity despite inadequate evidence of it. Patients become aggressive toward their partners as well as themselves, which is why in a fit of anger they can commit murder or suicide. Othello syndrome can occur as a symptom of an underlying mental illness, but it is most often associated with brain damage caused by chronic alcohol use. Antipsychotic drugs and serotonin reuptake inhibitors are used in pharmacotherapy. Targeted treatment using the neuropeptide oxytocin, which modulates the transmitter systems responsible for disease symptoms, is also being considered. The use of oxytocin seems groundbreaking, but it remains at the research stage. The treatment of addictions and primary diseases, as well as long-term cognitive-analytic psychotherapy, also have a huge impact. Othello syndrome is a life-threatening disease with an insidious course and serious consequences. This article aims to review the manifestations of morbid jealousy, including delusional disorder, and the association with alcoholism.
