“…For instance, there is little research concerning the role of sensory deficits in the development of hallucinations and delusions in children and adolescents. This is in sharp contrast with studies with adult and old-age populations that suggest a role for sensory deficits in hallucinations and delusions [100][101][102][103][104][105][106][107][108][109][110][111]. Preliminary evidence suggests that this is also the case in younger agegroups [112], although more work is clearly needed.…”

Studies have shown that hallucinations and delusions occur in a number of different populations including psychiatric and non-psychiatric patients and in non clinical (i.e. normal) individuals. However, the majority of these studies have included adult populations. The goal of the present article is to review the research on hallucinations and delusions in children and adolescents. The prevalence, characteristics and nature of hallucinations and delusions in both non clinical and clinical child and adolescent populations will be presented. In addition, a section on assessment strategies is included. Finally, the paper will conclude with a discussion of important issues and questions, including definitional issues, the predictive value of hallucinations and delusions, in addition to various clinical and theoretical implications.

“…Authors continue to debate the existence of sound-based auditory hallucinations in deaf people. Past studies found self-reported rates of auditory hallucinations in deaf patients with schizophrenia to be comparable to rates reported in hearing patients (52%-59%) [9,10]. However, these findings have been examined more recently in light of deafness-related variables demonstrating that a deaf patient with schizophrenia's perceptual experience of "voice" hallucinations relates closely to the individual's language and past auditory experiences [12].…”

“…The current consensus in the psychiatric literature is that similar to hearing patients, deaf patients with psychotic disorders experience hallucinations [9][10][11][12][13][14]. However, the manner in which hallucinations are manifested and experienced, particularly in prelingually deaf people (ie, deafness acquired prior to 3 years of age), remains unclear.…”

“…Visual hallucinations have long been thought to be more common in deaf patients than in hearing patients with schizophrenia, with reported rates ranging from 50% to 53% [9,10]. However, more recent research suggests that many of the "visual" hallucinations reported by deaf people with schizophrenia may actually be subvisual precepts (eg, perceptions of lips moving or being signed to in one's "mind's eye") as opposed to true visual hallucinations [12].…”

This article reviews recent research in the area of psychotic disorders in deaf psychiatric patients. Comparisons of the rates of psychotic disorders in the deaf and hearing populations suggest that psychotic disorders occur equally as often or even somewhat less often in the deaf population as in the hearing population. Consideration is given to the limitations of this small body of research, and recommendations for future research are provided. The contradictory literature on hallucinations in the deaf is also reviewed, and current theory about the manner in which hallucinations are manifested and experienced based on audiological history is presented. The challenges encountered by clinicians in accurately assessing symptoms of thought disorganization in deaf people are reviewed. Specifically, the etiology of deafness, language dysfluency, and the skill and training of American Sign Language interpreters are considered as factors impacting accurate diagnosis. Recommendations from the current literature are also provided.

“…Currently, most research on the experience of hallucinations in D/deaf persons has concentrated on the form or sensory modality of these experiences (e.g. Atkinson et al , 2007; Schonaeur et al , 1998). This may be due to the obvious interest in the question about whether D/deaf people do actually “hear voices”.…”

Purpose The purpose of this paper is to describe the lack of literature and research on command hallucinations (CHs) in D/deaf persons and make suggestions for assessment, instrument development and research into CHs in D/deaf persons. This is important since it is known that hallucinations are more common in persons with hearing impairment and because CHs are known to be associated not only with distress, but also suicide and homicide. Design/methodology/approach Articles on hallucinations and CHs in D/deaf persons are discussed in the context of existing literature on CHs in hearing persons. Findings When compared with the literature on hearing persons it is clear that very little is known about the prevalence of CHs in D/deaf persons and that there is a significant lack of research into emotional and behavioural responses to CHs in D/deaf persons. There is no knowledge about the effectiveness of cognitive behavioural therapy (CBT) for D/deaf persons who experience CHs. This is important since a CBT approach has been found to reduce risky compliance. Practical implications This paper makes recommendations for informed and evidence-based assessments of CHs in D/deaf persons; such assessments may have an important role in reducing risk and distress. Originality/value This is the first paper to review and consider CHs in D/deaf persons as a distinct clinical phenomenon. This paper makes recommendations for the assessment of D/deaf persons who experience CHs.
