A delusion [a] is a false fixed belief that is not amenable to change in light of conflicting evidence. [2] As a pathology, it is distinct from a belief based on false or incomplete information, confabulation, dogma, illusion, hallucination, or some other misleading effects of perception, as individuals with those beliefs are able to change or readjust their beliefs upon reviewing the evidence.
Delusional disorder, traditionally synonymous with paranoia, is a mental illness in which a person has delusions, but with no accompanying prominent hallucinations, thought disorder, mood disorder, or significant flattening of affect. [6] [7] Delusions are a specific symptom of psychosis.
A hallucination is a perception in the absence of an external stimulus that has the compelling sense of reality. [6] They are distinguishable from several related phenomena, such as dreaming (), which does not involve wakefulness; pseudohallucination, which does not mimic real perception, and is accurately perceived as unreal; illusion, which involves distorted or misinterpreted real ...
Auditory hallucinations have two essential components: audibility and alienation. [7] This differentiates it from thought insertion.

Ideas of reference and delusions of reference describe the phenomenon of an individual experiencing innocuous events or mere coincidences [1] and believing they have strong personal significance.

Persecutory delusion is at the more severe end of the paranoia spectrum and can lead to multiple complications, from anxiety to suicidal ideation. Persecutory delusions have a high probability of being acted upon, for example not leaving the house due to ...
Half of patients experience more than one kind of delusion. [2] Delusions occur without hallucinations in about one-half to two-thirds of patients with psychotic depression. [2] Hallucinations can be auditory, visual, olfactory (smell), or tactile (touch), and are congruent with delusional material. [2] Affect is sad, not flat.
Hallucinations may command a person to do something potentially dangerous when combined with delusions. [19] So-called "minor hallucinations", such as extracampine hallucinations, or false perceptions of people or movement occurring outside of one's visual field, frequently occur in neurocognitive disorders, such as Parkinson's disease.
