Morbid jealousy as a variant of obsessive-compulsive disorder.

OBJECTIVE: To present a representative case vignette and review several previous reports, and to then suggest that a percentage of those with morbid jealousy may have a variant of obsessive-compulsive disorder (OCD). CLINICAL PICTURE: A patient presented volunteering a diagnosis of depression and anxiety following recent work and marital stresses, before describing recent jealousy and harassment of his wife over an earlier relationship. Obsessional thinking patterns and compulsive behaviours are described, and it is proposed that the picture supports a diagnosis of obsessive-compulsive disorder. TREATMENT AND OUTCOME: The patient was treated as if he had an obsessive-compulsive disorder, and reported dissipation of his concerns after cognitive-behavioural intervention.
CONCLUSIONS: The proposition is an important one as a diagnosis of morbid jealousy often invites therapeutic pessimism, and as managements effective for OCD (both drug and behavioural) may well be helpful.
