Delusional disorder

Delusional disorder, also called as Psychosis, is a condition in which a person cannot differentiate between real and imaginary situations.

Such delusional state may also come along with hallucinations and they may hear voices, see figures or feel that they have bugs inside their skin.

NOTE: There is a substantial difference between psychotic disorders and delusional disorder as psychotic disorder as people with psychotic disorder may feel so delusional that their lives are completely disrupted. Although delusions are common for many disorders, it is a rare condition.

People going through delusional disorder may socialize and function in a normal manner and do not usually behave in a bizarre manner.

2. Biological: The imbalance of brain chemicals, also called neurotransmitters, has been linked to delusions as transmission of messages becomes a typical process.

3. Environmental or psychological: Delusional disorder may show up because of excessive stress. At the same time, if you are consuming alcohol and abusing yourself with drugs, your condition may worsen.

How Is Delusional Disorder Diagnosed?

If your physician feels that you are having symptoms of delusion disorder then he will run through your medical history and may ask you to perform certain examinations. Diagnostic tests like X ray and blood tests could be expected.

Once the physical issues are ruled out, the person is referred to a psychologist or psychiatrist or other mental health professionals who are trained to diagnose and treat the condition. The mental health professional uses specially designed tools to interview and assess the problems and prepares a report, based on the diagnosis.

It is important to remember that diagnosis is made on the criteria mentioned in Diagnostic & Statistical Manual of Mental Disorders (DSM-5).
