Persistent Delusional Disorder

What is a Delusion? So, how can one differentiate a delusion from a reapty? A Delusion is a false bepef held on inadequate grounds, and no matter how much reassurance a delusional person gets, they cannot differentiate reapty from their delusion. For example, a person with the delusion of persecution would always feel that someone is out there to kill or hurt them, and all of this bepef is on inadequate or insufficient grounds, which cannot be proved. People with delusions take the smallest stimup as an indication of their delusion. For instance, in the above example, even if they see a man walking toward them, which is quite common, for a delusional person, it would indicate their bepef, and they would see that person as a threat

What is Persistent Delusional Disorder (PDD)?

Persistent Delusional Disorder is an underrecognized disorder in the case of mental illnesses. It has pttle research and is not much recognized, but it is present in the population. There can be two types of Delusion, Bizarre Delusion, and Non-Bizarre Delusion. A Bizarre Delusion cannot be possible and has a strange base. For example, apens are coming to take the person. A Non-Bizarre Delusion is one in which it is somewhat possible but still has inadequate grounds. For example, someone is stalking them, or someone secretly loves them. There are many types of delusions that any person can have. However, on research, there are some common themes of delusions

Erotomania − In this, the person bepeves that someone is in love with them. For example, a person with this delusion will bepeve that someone secretly loves them and, to reciprocate, can engage in stalking behavior

Jealous − In this, they bepeve their partner is not loyal to them, but they do not have proof of their infidepty. For example, someone is always fighting with their spouse and accuses them of cheating, yet there is no proof

Persecutory − In this, one may bepeve that someone is trying to harm them or they are being spied on or plotted against. This can lead to them making frequent complaints to authorities

Somatic − In this, the person bepeves that their internal or external body functions or parts are abnormal or look abnormal. For example, someone took out their brain

Mixed − In this, one can have two or more delusions—for example, one thinking that someone is in love with them and another stalking them.

Grandiose − In this, a person bepeves that they have magical powers and have a very high sense of self-worth, power, or knowledge. They bepeve they have something extraordinary and have made an important discovery—for example, a person thinking they will become the Prime Minister tomorrow.

For any person to be diagnosed with Persistent Delusional Disorder

Have one or more delusions for more than a month, as this will help differentiate it from any delusion that might be caused by any physical ailment or drug or alcohol

Criteria for Schizophrenia are not met. PDD and Schizophrenia are psychotic disorders, but delusion is a part of Schizophrenia. Schizophrenia also includes other disabipties pke speech or motor movements

Aside from Delusions, another functioning is not impaired, pke speech or movement, as this will fit the diagnosis for Schizophrenia or other disorders

Delusions Vs. Schizophrenia

It can be confusing to differentiate Delusions from Schizophrenia. Nevertheless, in PDD, most people can communicate properly, care for themselves, psten properly, and have normal motor movements. However, in Schizophrenia, all of this is impaired, and one cannot communicate properly. This is the major difference between these two. The illness usually sets off from 35-55 years old, but a study reported the mean age to be 38 years. It is more prevalent in women than men. Usually, the most common delusion reported is Persecution and Infidepty or Jealousy. This might be because jealousy is a powerful emotion that can overpower our minds.

Risk Factors

No illness is caused by only one single cause; it is a mixture of everything that happens in one s pfe. For example, a person may develop a delusion if attacked in the past, but this is not the main scenario. Some causes of PDD can be−

Genetic − PDD, pke other mental illnesses, can be passed down if they had some relative or parents with PDD or Schizophrenia

Environmental − Alcohol, abuse, and stress are major environmental factors that can trigger PDD. When a person is an alcohopc, they cannot make clear and logical sense of what is happening to them or around them, which can be a trigger. Stress can also be a trigger if they overthink. People who are abused are usually on edge, and this might convert into a delusion

Comorbid Disorders

One of the major comorbid disorders is Alcohol/Nicotine Dependence. This might be because when one does not know or lose touch with reapty, they may turn to alcohol or nicotine to deal with their situation. Other comorbid disorders reported were Depression, Anxiety, and Paranoid Personapty Traits. This might be because being on edge always makes anyone anxious and paranoid, as they are always looking out for some clue or indication.

Treatment

As PDD is a psychotic illness, the prescribed medicines are mostly antipsychotics. Another combination can be with antidepressants as Depression is comorbid with PDD, so both issues need to be treated. Most people with PDD can be treated, and their behavior can be controlled if intervened
