You still claim that anything that people do not prove to you is not real. This is literally the definition of delusions caused by schizophrenia
Delusional disorder is a serious
mental illness where you can’t tell the difference between what’s real and what’s not. Delusions, or false beliefs, come in several types.
Delusions of grandeur are one of the more common ones. It’s when you believe that you have more power, wealth, smarts, or other grand traits than is true. Some people mistakenly call it “illusions” of grandeur.
Some delusions might be about events that possibly could have happened, but actually didn’t or were exaggerated. Other delusions are clearly bizarre, such as insisting that an alien lives in your fridge.
Symptoms
Even some healthy people can hold unreasonably high opinions of themselves. But unlike them, someone with grandiose delusions is unshakably convinced that their delusions are true.
For example, you may believe that you:
- Are a multimillionaire
- Found a cure for cancer
- Are related to a Hollywood celebrity
Other
symptoms may include:
Change in your mood. You may be irritable, angry, or feel low.
Hallucinations. You see, hear, or feel things connected to your delusion that aren’t really there. For example, if you believe that you have a special relationship with God, you may hear God’s voice.
Hallucinations aren’t very common with delusional disorders, and they tend not to last long.
Other than the delusion, someone with this condition doesn’t usually seem or act odd. But sometimes, the delusions can get serious enough to cause problems in their daily life.
Causes
Researchers don’t know exactly
what causes delusions. Sometimes, delusions of grandeur can be a symptom of another mental illnesses, including
bipolar disorder and
schizophrenia.
Grandiose delusions rarely happen by themselves. Most often, you are likely to also have delusions of persecution, a related condition where you’re convinced that others are out to harm, conspire against, or otherwise mistreat you.
Several things may play a role in delusional disorders:
Diagnosis
No test can confirm that you have a
delusional disorder. But your doctor will take a detailed mental history and rule out other medical causes to make a diagnosis.
You have this or another type of delusional disorder if you meet these criteria:
- You’ve had one or more delusions that lasted a month or longer.
- You have not been diagnosed with schizophrenia.
- You show obviously bizarre behavior other than your delusions.
- If you’ve had any episodes of mania or depression, they didn’t last longer than your delusional periods.
- Your delusions don’t stem from drugs, another medical condition, or a different mental disorder.
