What Is Delusional Disorder?
2. Causes
Mental health conditions are very complex and it can be very difficult to tell just what the cause is. However, there are some factors that appear to have a link to delusional disorder. One of these is genetic, and delusional disorder is more common in people that have a history of mental disorders in their family.
Some environmental factors are also associated with delusional disorder, and those with the condition will often have undergone prolonged periods of stress. People with sight and/or hearing problems are also more prone, as are people that live solitary lives. Alcohol and drug abuse are another potential factor, as is brain chemistry.
