Editing Pathological jealousy (section)

==Delusional jealousy==
This [[mental disorder|disorder]] is characterised by persistent suspicions of a partner’s infidelity that are not supported by the evidence. Individuals affected by the condition may misinterpret neutral behaviour as indications of unfaithfulness, which further reinforces their perceptions.<ref>{{Cite web|url=https://www.science.gov/topicpages/j/jealousy|title=jealousy: Topics by Science.gov|website=www.science.gov}}</ref>

Some studies have suggested that the disorder may co-occur with other conditions,including psychiatric disorders such as [[schizophrenia]] and [[delusional disorder]], as well as mood disorders such as [[bipolar disorder]]. It has also been associated with certain behaviours, including [[stalking]], [[cyberstalking]], [[sabotage]], [[alcoholism]] ,[[sexual dysfunction]], and neurological disorders such as [[Parkinson's disease]].<ref>{{Cite journal|url=https://pubmed.ncbi.nlm.nih.gov/8564326/|title=Morbid jealousy in alcoholism|first1=A.|last1=Michael|first2=S.|last2=Mirza|first3=K.

'''Pathological jealousy''' is generally identified through clinical assessment and is recognised as a possible feature of certain psychiatric conditions. According to the [[DSM-5|''Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition'' (DSM-5)]], it may be observed in disorders such as obsessive-compulsive [[Obsessive–compulsive disorder|obsessive-compulsive disorder]] and [[delusional disorder]]. While it is not classified as a distinct diagnostic category, pathological jealousy is often viewed as a manifestation of underlying mental health issues.<ref>{{cite book |title=Diagnostic and Statistical Manual of Mental Disorders: DSM-5 |publisher=American Psychiatric Association |year=2013 |isbn=978-0-89042-555-8 |edition=5th}}</ref>

The term "Othello Syndrome" is derived from the central character in [[William Shakespeare|Shakespeare]]’s tragedy ''[[Othello]]''. In the play,  Othello kills his wife Desdemona in the mistaken belief that she has been unfaithful to him. However, some scholars and experts have pointed out that Othello's actions resulted from manipulation and misinformation, which did not exhibit the clinical features of delusional disorder.<ref name="crichton_1996">Crichton, P.
