A person experiencing a delusion believes that his thoughts are real, while most people around him realize that his delusion is false.
Holothymic delirium – develops with affective disorders.
For example, in a manic state, delusions of grandeur arise, and in depression, ideas of self-abasement arise.
Catathymic and sensitive - develops during strong emotional experiences in people suffering from personality disorders or with hypersensitivity.
Delusional disorders are characterized by a poverty of symptoms: there are no persistent auditory hallucinations (“voices”), no sense of external control (a symptom of schizophrenia), no noticeable mood swings (severe depression or its opposite, mania).
Delusional personality disorder, if left untreated, will inevitably lead a person to serious consequences - loss of social contacts and skills, destruction of the family, alienation of relatives and friends.
The result of an untreated disease can be depression of varying degrees of severity and paranoia.
