Environmental/psychological: Evidence suggests that stress can trigger delusional disorder. Alcohol and drug abuse also might contribute to it. People who tend to be isolated, such as immigrants or those with poor sight and hearing, appear to be more likely to have delusional disorder.
Three specific phases are defined: the delusional, double-awareness, and nondelusional phases.
Most theorists agree on the first step, that delusions arise in the context of a delusional mood, an emotionally aroused state that makes the person hyperalert to threat. After that, some assume perception goes awry—something misheard or misperceived giving rise to increasing emotional upheaval and misinterpretation.
Delusions are common to several mental disorders and can be triggered by sleep disturbance and extreme stress, but they can also occur in physical conditions, including brain injury or tumor, drug addiction and alcoholism, and somatic illness.
People with delusional disorder may experience bizarre or non-bizarre delusions:3. Bizarre delusions: These are delusions that are physically impossible in our reality. For instance, the person may believe that an organ has been removed from their body without there being any evidence of the procedure.

Persecutory delusion
This is the most common form of delusional disorder. In this form, the affected person fears they are being stalked, spied upon, obstructed, poisoned, conspired against or harassed by other individuals or an organization.

Misidentification syndrome: the person believes someone they know has been replaced by an imposter who looks identical to that ...

Mary's persecutory delusions and somatic delusions both abated with treatment.
