Answer:

Delusions are fixed and firmly held beliefs that have no basis in reality. By definition, then a person who has a delusion believes in that delusion and is not aware that the delusion is in fact false. For this reason, If you yourself were delusional, chances are pretty good that you would not know it. Delusional people are typically people with either fairly serious neurological disorders (such as Schizophrenia or Alzheimer’s disease), or people with rigid, inflexible ways of understanding the world (such as some religious ‘fanatics’, and personality disordered people). Certain types of delusions appear with great regularity and can be classified into types. Erotomanic delusions involve the wrong-headed belief that some (famous) person is madly in love with you. Grandious delusions involve the belief that one is much greater and more important than they really are (for instance, the belief that you are Jesus Christ). Jealous delusions involve the belief that your spouse is cheating on you (when he/she is not). Persecutory delusions involve the belief that authorities or bad guys are coming to get you (when they are not). Somatic delusions involve the belief that one’s body is sick, infested with bugs, smelly, etc. when in actuality there is no such illness, infestation, etc. How does a delusional person generate their delusional beliefs? Good question. In my experience, usually, delusions start with a misinterpretation of something that has actually happened. So, a schizophrenic man I once knew saw a man walking down the street who (I suspect) looked a little like a family member. Due to his thought-disorder, he mis-interpreted this man for his brother, and started telling us that his brother was following him around. An Alzheimer’s patient will commonly misplace his/her wallet, forget where he or she put it, and will then start believing that other people around him/her are stealing from him/her. A religiously minded individual I knew in the middle of a manic episode once mistook the euphoria and odd sensations of bipolar disorder as a sign that he was the archangel Michael. The concrete and actual event is mis-interpreted, due to brain/cognitive impairments or rigid beliefs or both into an untrue belief that they continue to hold onto even in the face of no evidence.
