Chronic delusional disorders

Include a number of disorders in which persistent delirium is the only or most characteristic clinical symptom and which cannot be classified as organic, schizophrenic or affective.

Delusional disorder, formerly called paranoid disorder, is a type of serious mental illness called "psychosis" in which the patient cannot distinguish the real from the imaginary. The main characteristic of this disorder is the presence of delusional ideas, which are unshakable beliefs in something wrong. People with delusional disorders experience delusions that are not uncommon and include situations that may arise in real life, such as harassment, poisoning, misinformation, conspiracy against, or love at a distance. This delusion usually involves a misinterpretation of perception or experience. In reality, however, the situations are either untrue or greatly exaggerated.

What provokes / causes delusional disorder:
As with many other psychotic disorders, the exact cause of delusional disorders is still unknown. However, researchers are studying the role of various genetic, biological, psychological factors, as well as environmental factors.
- Genetic factor:

The fact that delusional disorder is more common in people with family members who have delusional disorder or suffer from schizophrenia suggests that a genetic factor may be involved. It is believed that, as with other mental disorders, the tendency to develop delusional disorder can be passed on to children from parents.

- Biological factor:

Researchers are studying how pathologies of certain areas of the brain may be involved in the development of delusional disorders. An imbalance of certain chemicals in the brain, called neurotransmitters, has also been linked to the formation of delusional symptoms. Neurotransmitters are substances that help nerve cells send messages to each other. An imbalance of these substances can adversely affect the transmission of messages, leading to symptoms.

- Environmental factor / psychological:

Evidence suggests that the trigger for delusional disorders may be stress. Alcohol and drug abuse can also contribute to the development of this condition. People who tend to be isolated, such as immigrants, have poor eyesight and hearing impairment and are more at risk for developing delusional disorder.

Treatment of delusional disorders:
Treatment of delusional disorders often includes drugs and psychotherapy (type of counseling). Delusional disorder is highly resistant to treatment only with medication.

Psychotherapy is the main treatment for delusional disorder, including psychosocial treatment, which can help with the behavioral and psychological problems associated with delusional disorder. With therapy, patients can also learn to control their symptoms, detect early warning signs of relapse, and develop a plan to prevent relapses.
