Delusional disorder, formerly known as paranoid disorder, is a severe kind of mental illness classified as psychosis. It occurs when a person is unable to discriminate between what is real and what is imagined. The presence of delusions, which are unwavering beliefs in something that is false, is the main sign of an illness.

People suffering from delusional disorder will have non-bizarre delusions about everyday settings. They consist of being poisoned, tricked, followed, loved distantly, or the target of a plot. Misinterpretation of experiences or perceptions is a common aspect of delusions. Yet, they're either completely false or greatly inflated.

A psychotic episode can include both delusions and hallucinations. Although delusions can come in many different forms, they are frequently divided into five major kinds. A combination of many illusion types falls under the sixth category. There are several types of delusional disorder:

1) Erotomanic

When you have an erotomanic illusion, you think you are in love with someone who has never met you in person. This misconception frequently includes a well-known figure. This may occasionally result in attempts to meet or speak with the person, as well as stalking.


2) Grandiose

This is often referred to as having lofty ideals. An exaggerated perception of one's own importance and value characterizes grandiose delusions. You might think you possess unique wisdom, superhuman strength, or other extraordinary qualities. You can also think that you're the only one who could make a discovery or resolve a grave problem.


3) Jealousy

Suspicions of adultery are a common component of jealous delusions. Even if you have no cause to suspect it, you might think your partner is cheating.

Those with delusional jealousy are entirely convinced that their partners have already been unfaithful recently or in the not-too-distant past, and their thoughts and conduct reflect this unwavering conviction. This is in contrast to those with obsessive jealousy.


4) Persecutory

The idea that you are being mistreated or oppressed by a person or group of people is a component of persecutory delusions. You might believe that someone is watching you or attempting to harm you. Misperception may cause extremely anxious feelings.


5) Somatic

An aspect of a somatic delusional disorder is the conviction that you suffer from a medical condition. You might think you have a parasite or an uncommon disease. Despite receiving assurances from doctors that you are healthy, you might also think you have a common medical condition.

Delusional disorder can be challenging to diagnose for a number of reasons. One of these is that those who have the disorder frequently don't discuss their inaccurate views and frequently function normally as a result. Another factor is that these people are unaware of how incorrect their views are and do not perceive anything wrong with their way of thinking. This can make people reluctant to have their mental health checked.

There are difficulties in differentiating between delusional disorder and other mental diseases with psychotic symptoms (schizophrenia) if a person can be persuaded to undergo evaluation. A mental health professional doing a diagnostic assessment must first decide if the patient is indeed experiencing delusions or whether their ideas are true.

To make this decision, speaking with family or friends may be helpful. Medical practitioners can determine whether delusions are present by observing the patient and conducting interviews.

Once delusional disorder has been identified in a person, additional disorders must be ruled out. An examination of the physical body aids in the exclusion of medical diseases, but a mental health specialist should also consider and screen for other psychotic conditions such as schizophrenia or manic stages of bipolar disorder.

Patients with delusional psychosis frequently lack insight. They don't realize how odd their thoughts and behaviors are. It's frequently up to the friends, family, or caregivers of a person affected by psychosis to seek help for them because of their lack of insight.

If you have concerns about a friend or family member and believe they may be experiencing delusional disorder, you should speak with their social worker or a community mental health nurse if they have already received a mental health diagnosis. You can bring the person to the closest accident and emergency department if you believe their symptoms put them in danger.


Stress can exacerbate the symptoms of delusional disorder in people who feel pressured or harshly criticized by others. A positive attitude may therefore be more beneficial and efficient.

People with delusional disorder frequently endure stress, depression, grief, and isolation from their friends and family. If you're exhibiting these signs, it's critical to look after your mental health and get assistance.
