What Causes Delusion?
As with other psychotic disorders, the exact cause of the delusional disorder is still idiopathic. However, looking at the role of various genetic, biological, and environmental factors.
The fact that the delusional disorder is more common in people who have family members with this disorder suggests there might be a genetic factor involved. It is believed that as with other mental conditions, a tendency to develop these disorders might be passed on from parents to their children.
Researchers are studying how abnormalities of certain areas of the brain involved in the development of delusional disorders. An imbalance of some chemicals in the brain is called neurotransmitters also has been linked with the formation of the symptoms of delusion. Neurotransmitters are substances that aid nerve cells in the brain to send messages. An imbalance in these chemicals can interfere with the transmission of messages resulting in symptoms.
Evidence suggests that delusional disorder can be triggered by stress where the main contributor to this condition is also alcohol and drug abuse. People who tend to be isolated such as those with poor sight appear to be more vulnerable to developing the delusional disorder.
