Hearing among children with neurological disorders

ABSTRACT

Background: Neurologic disorders are not rare in our environment but studies determining the hearing of these children are almost non- existent. This study therefore is to determine the prevalence of hearing loss in these children and also determine the care seeking attitude of the parents/guardians concerning the hearing.Methods: A hospital based descriptive study of all children attending the children neurologic clinic of university of Port Harcourt teaching hospital. A semi structured questionnaire was administered to parents / guardians who gave their consent for their children to be recruited into the study. Hearing loss in the children was taken as reported by the parents/guardians. Data collected were then entered into Microsoft Excel and then exported to the IBM Statistical Package for Social Sciences (SPSS) version 20 for statistical analysis.Results: The study comprised 49 children; 29 males and 20 females. Age range was from 8months to 18years.  Age group 1-5 years comprised the majority of the study population. Commonest neurological disorder seen was childhood epilepsy n=27, 55.1%. Prevalence of hearing loss was 26.5%. Children with childhood epilepsy had 15.4% having hearing loss while children with cerebral palsy, autistic spectrum disorder and microcephaly had 50% hearing loss recorded. Maternal illness during pregnancy was significantly related to the hearing loss with a p value = 0.045 and presence of neonatal illness with p value =0.009.  Only 7.7% was formally treated while 92.3% had no form of treatment whatsoever.Conclusions: Childhood epilepsy was the commonest type of neurologic disorder seen while highest point prevalence for hearing loss was in cerebral palsy. Majority of parents/caregivers did not seek medical care concerning the hearing loss neither were there any form of treatment given to the children.
