Editing Pathological jealousy (section)

===Psychological===
Morbid jealousy has been associated with a range of psychological factors. In some cases, it is conceptualized as a delusional state. According to Kingham and Gordon, “Delusions of [[infidelity]] exist without any other [[psychopathology]] and may be considered to be morbid jealousy in its ‘purest’ form.” The condition is often characterized by distorted memory processing and misinterpretation of a partner’s behavior, leading to a fixed conviction of betrayal despite the absence of objective evidence.

Certain [[brain disorder]]s have also been implicated in the development of delusional beliefs related to infidelity. Cobb (1979) noted that “morbid jealousy may be present with all types of cerebral insult or injury,” suggesting a neurological basis for some cases.<ref>{{cite journal | last1 = Cobb | first1 = J | year = 1979 | title = Morbid jealousy | journal = British Journal of Hospital Medicine | volume = 21 | issue = 5 | pages = 511–518 | pmid = 573647 }}</ref> Furthermore, it has been proposed that diminished sexual function may serve as a contributing factor in the emergence of morbid jealousy. Cobb highlighted instances involving elderly men whose declining sexual capacity was perceived as inadequate by significantly younger partners, potentially giving rise to pathological suspicion and jealousy.

Mullen (1990) considered morbid jealousy to be associated with four features: <ref>{{cite journal |last1=Cohen |first1=A.

* An underlying mental disorder emerges before or with the jealousy
* The features of the underlying disorder coexist with the jealousy
* The course of morbid jealousy closely relates to that of the underlying disorder
* The jealousy has no basis in reality
