Resumen
Objective: This systematic review aims to explore the various modalities through which hallucinations occur and comment on any patterns in the content described. Methods: Studies were identified by conducting a search of NICE databases using the key words “deaf” and “hallucinat*”. Databases included PubMed, PsychINFO, EMBASE, Medline, HMIC, HBE, CINAHL, BNI, AMED. The studies obtained were then assessed for inclusion according to the eligibility criteria. Both quantitative and qualitative data was extracted.
Results: 10 studies were included for the review. Prominent hallucinatory content included religion, sex, and hallucinatory content of a paranoid nature.
Auditory and visual hallucinations occurred to an almost equal degree, with both modalities being particularly prevalent. Conclusion: Numerous accounts of patients “hearing voices” were obtained, although significant debate surrounds this issue. Possible explanations for these findings are discussed in detail in regards to deafness history, psychodynamic factors and methodological biases. Greater efforts must be made by future researchers to tailor their design and methodology specifically to the deaf population. This will enhance the validity of findings and enable conclusions to be drawn more confidently
