A religious delusion is defined as a delusion, or fixed belief not amenable to change in light of conflicting evidence, involving religious themes or subject matter. [1] [2] Religious faith, meanwhile, is defined as a belief in a religious doctrine or higher power in the absence of evidence. [3] [4] Psychologists, scientists, and philosophers have debated the distinction between the two, which is subjective and cultural. [1] [5]
Individuals experiencing religious delusions are preoccupied with religious subjects that are not within the expected beliefs for an individual's background, including culture, education, and known experiences of religion. [6] These preoccupations are incongruous with the mood of the subject. Falling within the definition also are delusions arising in psychotic depression; however, these must present within a major depressive episode and be congruous with mood. [7] [8] [9] Some psychologists have characterized all or nearly all religion as delusion. [1] [5]
Researchers in a 2000 study found religious delusions to be unrelated to any specific set of diagnostic criteria, but correlated with demographic criteria, primarily age. [10] In a comparative study sampling 313 patients, those with religious delusion were found to be aged older, and had been placed on a drug regime or started a treatment programme at an earlier stage. In the context of presentation, their global functioning was found to be worse than another group of patients without religious delusions. The first group also scored higher on the Scale for the Assessment of Positive Symptoms (SAPS), [11] had a greater total on the Brief Psychiatric Rating Scale (BPRS), [12] and were treated with a higher mean number of neuroleptic medications of differing types during their hospitalization. [10]
Religious delusion was found in 2007 to strongly correlate with "temporolimbic overactivity". [13] This is a condition where irregularities in the brain's limbic system may present as symptoms of paranoid schizophrenia. [14] [15]
In a 2010 study, Swiss psychiatrists found religious delusions with themes of spiritual persecution by malevolent spirit-entities, control exerted over the person by spirit-entities, delusional experience of sin and guilt, or delusions of grandeur. [9]
Religious delusions have generally been found to be less stressful than other types of delusion. [10] A study found adherents to new religious movements to have similar delusionary cognition, as rated by the Delusions Inventory, to a psychotic group, although the former reported feeling less distressed by their experiences than the latter. [16]
Behaviours out of the ordinary were traditionally viewed as demonic possession. [17] These episodes, although entirely disavowed by modern psychiatry, [18] are evaluated by clinicians only such that they fall within the safety of a treatment programme.
In 1983 propositions that religious shamans were motivated by delusions and that their behaviour resembled that of patients with schizophrenia were found to be incorrect. [19]
In a 1937 essay, Sigmund Freud stated that he considered believing in a single god to be a delusion, [1] thus extending his 1907 comment that religion is the indication of obsessional neurosis. [20] [21] His thoughts defining "delusion" perhaps crystallized from the notion of the religion formulations of the common man (circa 1927) as "patently infantile, foreign to reality"; [22] around the same year he also stated that religion "comprises a system of wishful illusions together with a disavowal of reality, such as we find in an isolated form nowhere else but amentia, in a state of blissful hallucinatory confusion". [23]
Examples from a 295-subject study in Lithuania showed that the most common religious delusions were being a saint (in women) and being God (in men). [24]
In one study of 193 people who had previously been admitted to hospital and subsequently diagnosed with schizophrenia, 24% were found to have religious delusions. [25]
A 1999 study identified that religious delusions were often present or expressed in persons with forensic committal to a psychiatric unit. [26] [9]
Researchers have discussed whether historical figures may have had religious delusions.
Although many researchers have brought evidence for a positive role that religion plays in health, others have shown that religious practices and experiences may be linked to mental illnesses of various kinds (mood disorders, personality disorders, psychiatric disorders). In 2011, a team of psychiatrists, behavioral psychologists, neurologists and neuropsychiatrists from the Harvard Medical School published research that suggested the development of a new diagnostic category of psychiatric disorders related to religious delusion and hyperreligiosity. [27]
They compared the thought and behavior of the most important figures in the Bible (Abraham, Moses, Jesus Christ and Paul) [27] with patients affected by mental disorders related to the psychotic spectrum using different clusters of disorders and diagnostic criteria (DSM-IV-TR), [27] and concluded that these Biblical figures "may have had psychotic symptoms that contributed inspiration for their revelations", [27] such as schizophrenia, schizoaffective disorder, manic depression, delusional disorder, delusions of grandeur, auditory-visual hallucinations, paranoia, Geschwind syndrome (Paul especially) and abnormal experiences associated with temporal lobe epilepsy (TLE). [27]
In 1998–2000 Pole Leszek Nowak (born 1962) [28] from Poznań authored a study in which, based on his own history of religious delusions of mission and overvalued ideas, and information communicated in the Gospels, made an attempt at reconstructing Jesus' psyche with the view of Jesus as apocalyptic prophet. [29] He does so in chapters containing, in sequence, an analysis of character traits of the "savior of mankind", a description of the possible course of events from the period of Jesus' public activity, a naturalistic explanation of his miracles. [30]
A religious experience of communication from heavenly or divine beings could be interpreted as a test of faith. An example of such is Joan of Arc, La Pucelle d'Orléans, [31] who rallied French forces late in the Hundred Years' War.
Daniel Paul Schreber is an example of a supposed religious delusion occurring in a developed condition of psychosis. [32] Schreber was a successful and highly respected German judge until middle age, when he came to believe that God was turning him into a woman. Two of his three illnesses (1884–1885 and 1893–1902) are described in his book Memoirs of My Nervous Illness (original German title Denkwürdigkeiten eines Nervenkranken), [33] which became an influential book in the history of psychiatry and psychoanalysis thanks to its interpretation by Sigmund Freud. [34]
The Harvard Medical School research also focused on social models of psychopathology, [27] analyzing new religious movements and charismatic cult leaders such as David Koresh, leader of the Branch Davidians, [27] and Marshall Applewhite, founder of the Heaven's Gate cult. [27] The researchers concluded that "If David Koresh and Marshall Applewhite are appreciated as having psychotic-spectrum beliefs, then the premise becomes untenable that the diagnosis of psychosis must rigidly rely upon an inability to maintain a social group. A subset of individuals with psychotic symptoms appears [sic] able to form intense social bonds and communities despite having an extremely distorted view of reality. The existence of a better socially functioning subset of individuals with psychotic-type symptoms is corroborated by research indicating that psychotic-like experiences, including both bizarre and non-bizarre delusion-like beliefs, are frequently found in the general population. This supports the idea that psychotic symptoms likely lie on a continuum." [27]
An individual may hear communication from heavenly or divine beings compelling one to commit acts of violence. Some cite the case of the Hebrew patriarch Abraham, [35] who was commanded by God to sacrifice his son Isaac. However, when Abraham was prepared to act on it, God informed him that this was only a test of faith and forbade any human sacrifice.
In contemporary times persons judged to have experienced auditory hallucination include those hearing voices instructing or motivating them to commit violent acts. These auditory experiences are classified by psychiatry as command hallucination. [36] Persons acting to commit murder are reported as hearing voices of religious beings such as God, [37] [38] [39] [40] [41] [42] [43] [44] angels, [45] or the Devil. [46]
Thomas Szasz critiques the concept of religious auditory hallucination: those who hear the voice of God talking to them are experiencing schizophrenia, while those who talk to God but hear no response are simply praying. [47]
Psychosis is a condition of the mind or psyche that results in difficulties determining what is real and what is not real. Symptoms may include delusions and hallucinations, among other features. Additional symptoms are disorganized thinking and incoherent speech and behavior that is inappropriate for a given situation. There may also be sleep problems, social withdrawal, lack of motivation, and difficulties carrying out daily activities. Psychosis can have serious adverse outcomes.
Schizophrenia is a mental disorder characterized variously by hallucinations, delusions, disorganized thinking and behavior, and flat or inappropriate affect. Symptoms develop gradually and typically begin during young adulthood and are never resolved. There is no objective diagnostic test; diagnosis is based on observed behavior, a psychiatric history that includes the person's reported experiences, and reports of others familiar with the person. For a diagnosis of schizophrenia, the described symptoms need to have been present for at least six months or one month. Many people with schizophrenia have other mental disorders, especially mood disorders, anxiety disorders, and obsessive–compulsive disorder.
A delusion is a false fixed belief that is not amenable to change in light of conflicting evidence. 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. However:
Schizoaffective disorder is a mental disorder characterized by symptoms of both schizophrenia (psychosis) and a mood disorder - either bipolar disorder or depression. The main diagnostic criterion is the presence of psychotic symptoms for at least two weeks without prominent mood symptoms. Common symptoms include hallucinations, delusions, disorganized speech and thinking, as well as mood episodes. Schizoaffective disorder can often be misdiagnosed when the correct diagnosis may be psychotic depression, bipolar I disorder, schizophreniform disorder, or schizophrenia. This is a problem as treatment and prognosis differ greatly for most of these diagnoses. Many people with schizoaffective disorder have other mental disorders including anxiety disorders.
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. Delusions are a specific symptom of psychosis. Delusions can be bizarre or non-bizarre in content; non-bizarre delusions are fixed false beliefs that involve situations that could occur in real life, such as being harmed or poisoned. Apart from their delusion or delusions, people with delusional disorder may continue to socialize and function in a normal manner and their behavior does not necessarily seem odd. However, the preoccupation with delusional ideas can be disruptive to their overall lives.
A thought disorder (TD) is a disturbance in cognition which affects language, thought and communication. Psychiatric and psychological glossaries in 2015 and 2017 identified thought disorders as encompassing poverty of ideas, neologisms, paralogia, word salad, and delusions—all disturbances of thought content and form. Two specific terms have been suggested—content thought disorder (CTD) and formal thought disorder (FTD). CTD has been defined as a thought disturbance characterized by multiple fragmented delusions, and the term thought disorder is often used to refer to an FTD: a disruption of the form of thought. Also known as disorganized thinking, FTD results in disorganized speech and is recognized as a major feature of schizophrenia and other psychoses. Disorganized speech leads to an inference of disorganized thought. Thought disorders include derailment, pressured speech, poverty of speech, tangentiality, verbigeration, and thought blocking. One of the first known cases of thought disorders, or specifically OCD as it is known today, was in 1691. John Moore, who was a bishop, had a speech in front of Queen Mary II, about "religious melancholy."
Paul Eugen Bleuler was a Swiss psychiatrist and humanist most notable for his contributions to the understanding of mental illness. He coined several psychiatric terms including "schizophrenia", "schizoid", "autism", depth psychology and what Sigmund Freud called "Bleuler's happily chosen term ambivalence".
Kurt Schneider was a German psychiatrist known largely for his writing on the diagnosis and understanding of schizophrenia, as well as personality disorders then known as psychopathic personalities.
Stimulant psychosis is a mental disorder characterized by psychotic symptoms. It involves and typically occurs following an overdose or several day binge on psychostimulants, although it can occur in the course of stimulant therapy, particularly at higher doses. One study reported occurrences at regularly prescribed doses in approximately 0.1% of individuals within the first several weeks after starting amphetamine or methylphenidate therapy. Methamphetamine psychosis, or long-term effects of stimulant use in the brain, depend upon genetics and may persist for some time.
Daniel Paul Schreber was a German judge who was famous for his personal account of his own experience with schizophrenia. Schreber experienced three distinct periods of acute mental illness. The first of these, in 1884-1885 was what was then diagnosed as dementia praecox. He described his second mental illness, from 1893 to 1902, making also a brief reference to the first disorder from 1884 to 1885, in his book Memoirs of A Nervous Illness. The Memoirs became an influential book in the history of psychiatry and psychoanalysis because of its interpretation by Sigmund Freud. There is no personal account of his third disorder, in 1907–1911, but some details about it can be found in the Hospital Chart. During his second illness he was treated by Paul Flechsig, Pierson (Lindenhof), and Guido Weber.
The mental status examination (MSE) is an important part of the clinical assessment process in neurological and psychiatric practice. It is a structured way of observing and describing a patient's psychological functioning at a given point in time, under the domains of appearance, attitude, behavior, mood and affect, speech, thought process, thought content, perception, cognition, insight, and judgment. There are some minor variations in the subdivision of the MSE and the sequence and names of MSE domains.
Thought broadcasting is a type of delusional condition in which the affected person believes that others can hear their inner thoughts, despite a clear lack of evidence. The person may believe that either those nearby can perceive their thoughts or that they are being transmitted via mediums such as television, radio or the internet. Different people can experience thought broadcasting in different ways. Thought broadcasting is most commonly found among people who have a psychotic disorder, specifically schizophrenia.
Paraphrenia is a mental disorder characterized by an organized system of paranoid delusions with or without hallucinations and without deterioration of intellect or personality.
An auditory hallucination, or paracusia, is a form of hallucination that involves perceiving sounds without auditory stimulus. While experiencing an auditory hallucination, the affected person hears a sound or sounds that did not come from the natural environment.
Grandiose delusions (GDs), also known as delusions of grandeur or expansive delusions, are a subtype of delusion characterized by the extraordinary belief that one is famous, omnipotent, wealthy, or otherwise very powerful or of a high status. Grandiose delusions often have a religious, science fictional, or supernatural theme. Examples include the extraordinary belief that one is a deity or celebrity, or that one possesses fantastical talents, accomplishments, or superpowers.
Brief psychotic disorder—according to the classifications of mental disorders DSM-IV-TR and DSM-5—is a psychotic condition involving the sudden onset of at least one psychotic symptom lasting 1 day to 1 month, often accompanied by emotional turmoil. Remission of all symptoms is complete with patients returning to the previous level of functioning. It may follow a period of extreme stress including the loss of a loved one. Most patients with this condition under DSM-5 would be classified as having acute and transient psychotic disorders under ICD-10. Prior to DSM-IV, this condition was called "brief reactive psychosis." This condition may or may not be recurrent, and it should not be caused by another condition.
A persecutory delusion is a type of delusional condition in which the affected person believes that harm is going to occur to oneself by a persecutor, despite a clear lack of evidence. The person may believe that they are being targeted by an individual or a group of people. Persecution delusions are very diverse in terms of content and vary from the possible, although improbable, to the completely bizarre. The delusion can be found in various disorders, being more usual in psychotic disorders.
Childhood schizophrenia is similar in characteristics of schizophrenia that develops at a later age, but has an onset before the age of 13 years, and is more difficult to diagnose. Schizophrenia is characterized by positive symptoms that can include hallucinations, delusions, and disorganized speech; negative symptoms, such as blunted affect and avolition and apathy, and a number of cognitive impairments. Differential diagnosis is problematic since several other neurodevelopmental disorders, including autism spectrum disorder, language disorder, and attention deficit hyperactivity disorder, also have signs and symptoms similar to childhood-onset schizophrenia.
The diagnosis of schizophrenia, a psychotic disorder, is based on criteria in either the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, or the World Health Organization's International Classification of Diseases (ICD). Clinical assessment of schizophrenia is carried out by a mental health professional based on observed behavior, reported experiences, and reports of others familiar with the person. Diagnosis is usually made by a psychiatrist. Associated symptoms occur along a continuum in the population and must reach a certain severity and level of impairment before a diagnosis is made. Schizophrenia has a prevalence rate of 0.3-0.7% in the United States.
The relationship between religion and schizophrenia is of particular interest to psychiatrists because of the similarities between religious experiences and psychotic episodes. Religious experiences often involve reports of auditory and/or visual phenomena, which sounds seemingly similar to those with schizophrenia who also commonly report hallucinations and delusions. These symptoms may resemble the events found within a religious experience. However, the people who report these religious visual and audio hallucinations also claim to have not perceived them with their five senses, rather, they conclude these hallucinations were an entirely internal process.
