One challenge for caregivers and family members is to keep in mind that the disease is causing these delusional behaviors. An Alzheimer’s patient suffering a delusion may be overwhelmingly suspicious of the people around them, believing that family members or caretakers are trying to trick them and steal their possessions, or that the government or police are following them, or any number of highly paranoid scenarios. The primary distinction is that, unlike a hallucination, a delusion involves a set of false beliefs. Meanwhile, as alz.org explains, a delusion is not the same thing as a hallucination. There’s no way to deal with it rationally or directly.
“And if on another day Mom thought I was her boyfriend from high school,” he says, “that’s who I became. Hoag how they miss he and his mother’s spontaneous supermarket performances. Stephen Hoag, author of A Son’s Handbook: Bringing Up Mom with Alzheimer’s/Dementia, he describes how when he took his mother, a former vaudeville performer, to the big grocery store in town, “Mom would see all these people as an audience and say, ‘You’re on next!’ So I’d take it away, singing and dancing with her and entertaining everyone.” This is an endearing example of the hallucinations that accompany Alzheimer’s - and indeed, that specific one happened often enough that the locals still tell Dr. This article uses material summarized from the DSM-IV.While a hallucination may be frightening in nature - for instance, a person may feel and see bugs crawling up their legs - it can also involve visions of the past and the sense of reliving old experiences.

Certain types of auditory hallucinations (i.e., two or more voices conversing with one another or voices maintaining a running commentary on the person’s thoughts or behavior) have been considered to be particularly characteristic of Schizophrenia. Hallucinations may be a normal part of religious experience in certain cultural contexts. Isolated experiences of hearing one’s name called or experiences that lack the quality of an external percept (e.g., a humming in one’s head) should also not be considered as symptomatic of Schizophrenia or any other Psychotic Disorder. The hallucinations must occur in the context of a clear sensorium those that occur while falling asleep (hypnagogic) or waking up (hypnopompic) are considered to be within the range of normal experience. Auditory hallucinations are usually experienced as voices, whether familiar or unfamiliar, that are perceived as distinct from the person’s own thoughts. Hallucinations may occur in any sensory modality (e.g., auditory, visual, olfactory, gustatory, and tactile), but auditory hallucinations are by far the most common. Delusions that express a loss of control over mind or body are generally considered to be bizarre these include a person’s belief that his or her thoughts have been taken away by some outside force (“thought withdrawal”), that alien thoughts have been put into his or her mind (“thought insertion”), or that his or her body or actions are being acted on or manipulated by some outside force (“delusions of control”).Īn example of a nonbizarre delusion is a person’s false belief that he or she is under surveillance by the police. An example of a bizarre delusion is a person’s belief that a stranger has removed his or her internal organs and has replaced them with someone else’s organs without leaving any wounds or scars. Delusions are deemed bizarre if they are clearly implausible and not understandable and do not derive from ordinary life experiences.
The distinction between a delusion and a strongly held idea is sometimes difficult to make and depends in part on the degree of conviction with which the belief is held despite clear contradictory evidence regarding its veracity.Īlthough bizarre delusions are considered to be especially characteristic of schizophrenia, “bizarreness” may be difficult to judge, especially across different cultures. Referential delusions are also common the person believes that certain gestures, comments, passages from books, newspapers, song lyrics, or other environmental cues are specifically directed at him or her. Persecutory delusions are most common the person believes he or she is being tormented, followed, tricked, spied on, or ridiculed. Their content may include a variety of themes (e.g., persecutory, referential, somatic, religious, or grandiose). Delusionsĭelusions are false or erroneous beliefs that usually involve a misinterpretation of perceptions or experiences. Hallucinations, on the other hand, tend to only appear in people with schizophrenia or a psychotic disorder. Delusions are a symptom of some mental disorder, such as schizophrenia, delusional disorder, schizoaffective disorder, and schizophreniform disorder.
