Pathological jealousy is grounded in specific neuropsychiatric and psychological factors, with evidence linking it to underlying psychiatric conditions, organic brain abnormalities, and neurotransmitter dysregulation.
The retrieved literature consistently supports the claim that pathological jealousy (often studied as Othello syndrome or delusional jealousy) stems from specific psychological conflicts and neurological/medical etiologies, such as dopaminergic dysfunction, cerebrovascular accidents, dementia, and psychiatric disorders. Papers [8] and [9] explicitly detail these psychological and neurobiological factors without any papers contradicting the general premise that the condition has specific causes.
