Auditory hallucinations in childhood: associations with adversity and delusional ideation.
Summary of "Auditory hallucinations in childhood: associations with adversity and delusional ideation."
Previous work suggests that exposure to childhood adversity is associated with the combination of delusions and hallucinations. In the present study, associations between (severity of) auditory vocal hallucinations (AVH) and (i) social adversity [traumatic experiences (TE) and stressful events (SE)] and (ii) delusional ideation were examined.MethodA baseline case-control sample of children with and without AVH were re-assessed on AVH after 5 years and interviewed about the experience of social adversity and delusions.
A total of 337 children (mean age 13.1 years, s.d.=0.5) were assessed: 40 children continued to hear voices that were present at baseline (24%, persistent group), 15 heard voices only at follow-up (9%, incident group), 130 children no longer reported AVH that were present at baseline (remitted group) and 152 never heard voices (referent group). Both TE and SE were associated with both incident and persistent AVH, as well as with greater AVH severity and delusional ideation at follow-up. In addition, the combination of AVH and delusions displayed a stronger association with TE and SE compared with either AVH or delusions alone.
Early childhood AVH are mostly benign and transitory. However, experience of social adversity is associated with persistence, severity and onset of new AVH closer to puberty, and with delusional ideation.

Medical and Biotech [MESH] Definitions
Neurologic disorders occurring in children following lead exposure. The most frequent manifestation of childhood lead toxicity is an encephalopathy associated with chronic ingestion of lead that usually presents between the ages of 1 and 3 years. Clinical manifestations include behavioral changes followed by lethargy; CONVULSIONS; HALLUCINATIONS; DELIRIUM; ATAXIA; and vomiting. Elevated intracranial pressure (HYPERTENSION, INTRACRANIAL) and CEREBRAL EDEMA may occur. (From Adams et al., Principles of Neurology, 6th ed, p1210-2)
Chronic mental disorders in which there has been an insidious development of a permanent and unshakeable delusional system (persecutory delusions or delusions of jealousy), accompanied by preservation of clear and orderly thinking. Emotional responses and behavior are consistent with the delusional state.
Disorders of hearing or auditory perception due to pathological processes of the AUDITORY PATHWAYS in the CENTRAL NERVOUS SYSTEM. These include CENTRAL HEARING LOSS and AUDITORY PERCEPTUAL DISORDERS.
Acquired or developmental cognitive disorders of AUDITORY PERCEPTION characterized by a reduced ability to perceive information contained in auditory stimuli despite intact auditory pathways. Affected individuals have difficulty with speech perception, sound localization, and comprehending the meaning of inflections of speech.
Loss of sensitivity to sounds as a result of auditory stimulation, manifesting as a temporary shift in auditory threshold. The temporary threshold shift, TTS, is expressed in decibels.
