| Description |
Hallucinations are perceptions without external stimulation of the relevant sensory organ. Individuals vary in the degree of insight they possessthat is, whether they recognize these experiences as being ""not real."" Some propose the term ""pseudohallucinations"" for experiences with preserved insight. However, insight can fluctuate over time in an individual (sometimes it is gained only after attempted interaction with the phantom) and can vary within a group with a common pathology. Also there is no proof that insight has any pathogenetic significance, other than that it may correlate with the degree of associated cognitive or psychiatric impairment. Therefore, the term ""hallucinations"" is probably best used for all such experiences, regardless of insight. |
