Conclusions
Morbid jealousy is a symptom rather than a diagnosis. It may take the form of a delusion, an obsession or an overvalued idea, or combinations of these. The nature of its form, and other features evident from the history and mental state examination, should reveal the underlying diagnosis – or diagnoses – and allow appropriate management. Undoubtedly, alcohol misuse is an important association, and any substance misuse should be treated as a priority.
Morbid jealousy has the potential to cause enormous distress to both partners within a relationship and to their family. It carries with it a risk of serious violence and suicide. Clearly, early identification and treatment are most important to prevent serious harm, and vigilance should be maintained. Risk management includes hospital admission of morbidly jealous individuals where necessary, together with taking steps to protect potential victims. The modern clinician has a variety of drug treatments and psychosocial approaches with which to tackle the disorder, and the prognosis may not be as bleak as was once thought. Given the potential for tragic consequences, morbid jealousy is a symptom to be treated vigorously.
