Delusions

Anatomy or system affected: Psychic-emotional system

Definition:False beliefs regarding the self, other persons, or inanimate objects that persist despite reality; a feature of paranoia, schizophrenia, and psychotic states

Causes and Symptoms

Clinical delusion is defined as the presence of one or more “non-bizarre” false beliefs persisting for a period of at least one month. This term refers to situations that could occur in real life, while a “bizarre” belief could not. Delusions are not typically linked to the direct physiological effects of a substance or a general medical condition. Whether a false belief can be classified as non-bizarre may be difficult to determine.

Delusions and hallucinations are a common condition for those afflicted with dementia. Dementia is a general category of symptoms common to those experiencing memory loss and other forms of cognitive decline. The difference between a delusion and a hallucination is that a delusion is an unfounded or unsupported belief held by a person. These can be threatening in nature and involve a sense of loss, such as the belief by a person that their partner is having an affair or robbing them of money. A hallucination is a sensory experience, such as the sense that a person has actually seen or heard an event that never transpired. A form of dementia called Lewy Body dementia results in well-formed visual hallucinations and impacts approximately 80% of those with this condition. Alzheimer’s Disease is a form of dementia characterized by its degenerative impacts on the human brain, which worsen over time. Hallucinations occur in sufferers of Alzheimer’s, although the number of occurrences may be relatively small.

Life management with delusions varies. Some individuals may appear relatively unimpaired in their interpersonal and occupational roles. In others, life-management issues may be so severe that isolation and withdrawal are common results. In general terms, life-management functions are more likely to be adversely affected than cognitive or vocational activities.

Treatment and Therapy

Options for treatment and therapy vary depending on the severity of the delusions, the degrading effects on life-management issues, and the theoretical orientation of the mental-health professional consulted. A thorough evaluation should begin the process. Clinical interviews should be combined with appropriate psychological testing and corroborative data collection. Therapy may be in the form of pharmacological therapy or talk therapies, either in individual or group sessions, and may take place on an inpatient or outpatient basis. Delusions tend to wax and wane in intensity and degrees of severity. Maintaining good general physical health is an important part of managing delusions. Maintenance of neurochemical systems, especially neurotransmitters, with vitamin-B complex foods is an important consideration. Caregivers of persons suffering from delusions should avoid arguing with the patient about their deluded beliefs and should reassure the patient if he or she is scared.

Perspective and Prospects

Delusions in and of themselves may not prevent successful life-management functioning in most individuals. When the delusion represents a life-management issue as a result of a loss of contact with reality, intervention and treatment are in the patient’s best interest. Although popular media and common myths suggest otherwise, individuals with delusions are no more dangerous or aggressive than the general population. While they may be the targets of ridicule, challenge, and harassment, individuals with delusions may also reorient successfully with appropriate intervention.
