The delusional disorder that spreads at a rate of 60% in society.

False beliefs can be common occurrences that we often witness or experience in our society, such as marital infidelity, thoughts of living in European countries, or daydreaming in general.

Delusional disorder typically affects young people. This condition is less common than schizophrenia. Delusional disorder can be distinguished from schizophrenia by the presence of delusions without any other psychotic symptoms, such as hallucinations, disorganized speech, or disturbed behavior.

Delusions may involve situations that can be imagined in real life, such as feeling persecuted, infected, or having someone secretly love them without telling them, or attempting to poison them. Delusions may also involve situations that are unlikely to occur.

The difference between delusion and false or erroneous belief is that delusional patients continue to believe in their delusions regardless of clear and obvious contradictory evidence. 

Types of delusional disorder: 

There are several subtypes of delusional disorder:

Erotomanic delusion: The patient believes that someone else is in love with them.

The patient often tries to communicate with the person of their delusion through phone calls, messages, or electronic correspondence.

Some patients may attempt to monitor or track others. The behavior associated with delusions may be illegal.

Grandiose delusion: The patient is convinced that they have great talents or have discovered extremely important things.

Jealous delusion: The patient believes that their spouse or lover is unfaithful to them.

This belief is based on incorrect inferences supported by questionable evidence.

In these circumstances, the risk of the patient committing physical assault may increase.

Persecutory delusion: The patient believes that they are the victim of a conspiracy, surveillance, mistreatment, or harassment. The patient may repeatedly file lawsuits or complaints with the police or other government agencies.

In rare cases, the patient may resort to violence to retaliate against the alleged enemy.

Somatic delusion: The patient is preoccupied with an idea related to their physical characteristics or bodily functions, such as having a physical deformity or emitting a foul odor.

The delusion can also take the form of an imagined medical condition, such as being infected with parasites.

Symptoms of delusional disorder:

Delusional disorder may develop from a previous history of paranoid personality disorder.

Patients with paranoid personality disorder may have had a lack of trust and doubts about others and their motives since early adolescence.

Early symptoms of delusional disorder may include:

- Feeling exploited by others.

- Attaching great importance to feelings of loyalty and trust towards friends.

- Interpreting aggression towards them in ordinary and harmless incidents.

- Bearing grudges for a long time.

- Reacting immediately to perceived insults.

The patient's behavior is not clearly strange or unusual. Patients with delusional disorder tend to perform their daily activities relatively well, except in situations where their delusions cause problems.

For example, a patient may lead a normal married life unless they delude themselves into believing in marital infidelity.

Treatment of delusional disorder:

Treatment can be challenging because some patients firmly believe in the truth of their delusions and refuse help.

A good doctor-patient relationship can be beneficial. Once a good relationship is established, the doctor can encourage treatment-resistant patients to start therapy.

The long-term goal of treatment is to redirect the patient's focus away from their delusions toward more constructive and satisfying things, although achieving this goal

may be difficult.
