A delusion is a strong belief that is held in conviction despite there being evidence to prove that the contrary is true. The belief that the person has is trigger than the evidence that you provide to him or her. And they stand by thier statements whatever someone says. Delusions in medico legal services are normally categorized into 4 groups. This that are bizarre and non bizarre and those that are mood compatible and those that are not. The terms themselves are self explanatory. Mood compatible meaning that you will find that the delusions that the patient is having is not in line with the mood reflected by the patient.
It is a chronic and unshakable delusional system which develops insidiously in a person in middle or late life. This gradual onset is what makes it look so real. The delusional system is encapsulated and other mental functions are normal with the patient maintaining reasonable work and social life. It is commonly found in a medico legal psychological assessment. Specific delusional syndromes include morbid jealousy as one type where the prominent feature is the abnormal belief that the sexual partner is unfaithful. The clinical features of this condition include other abnormal beliefs that the partner is plotting against the patient. Moods such as misery, apprehension, irritability and anger. Behavior such as intensive seeking of evidence of the partner’s infidelity, following the partner about or engaging a detective, cross-questioning the partner incessantly and constant quarreling which may lead to assault and murder as well.In the assessment we should try to find out the power of the jealous person’s belief in the partners unfaithfulness. The amount of bitterness, and if vengeful action has been considered. Aggravating factors for outburst of resentment, accusation and cross-questioning. The partner’s reply to these outbursts. The patient’s answer to the partner’s behavior. If there has been any violenceThe partner should be seen alone to allow a better account of the patient’s morbid beliefs and activities. Treatment of patients with such a condition is done using an antipsychotic such as Trifluoperazine or Chlorpromazine may help reduce the strength of the jealous beliefs and the emotional uproar. Open conversation of the problem may help reduce the emotional tension. The partner should be directed to adjust their behavior so that it is least infuriating to the patient. If the risk of violence is high from the get go or if there is no response to treatment then hospital admission may be required. If treatment fails then temporary or lasting separation may be necessary to protect the partner
