Insights
Children with profound sensorineural hearing loss (SNHL) and behavioral issues show a higher prevalence of epileptiform discharges (EDs) on EEG. This suggests a potential link between hearing loss, behavioral problems, and neurological activity in children.
Area of Science:
- Pediatric Neurology
- Neurophysiology
- Audiology
Background:
- Overactivity and behavioral problems are common in children with prelingual profound sensorineural hearing loss (SNHL).
- Limited data exists on epileptiform electroencephalography (EEG) discharges in deaf children with psychological disorders.
Purpose of the Study:
- To determine the prevalence of epileptiform discharges (EDs) in children with SNHL who also exhibit overactivity or behavioral problems.
- To investigate the association between SNHL, behavioral issues, and neurological findings.
Main Methods:
- A cohort of 262 children with prelingual profound SNHL was studied.
- EEG was performed on children diagnosed with overactivity and/or behavioral problems by a pediatric psychiatrist.
- A control group of 45 children with normal hearing and similar behavioral issues was included for comparison.
Main Results:
- Epileptiform discharges (EDs) were detected in 20.02% of children with SNHL and behavioral problems.
- In the control group (normal hearing, behavioral problems), EDs were found in 8.88% of cases.
- The difference in ED prevalence between the SNHL group and the control group was statistically significant.
Conclusions:
- Deaf children with overactivity and/or behavioral problems exhibit a higher frequency of EDs compared to hearing children with similar behavioral issues.
- Further research is needed to explore the potential association between SNHL and EDs in overactive children.
Objective:
Overactivity and behavioral problems are common problems in children with prelingually profound sensorineural hearing loss (SNHL). Data on epileptiform electroencephalography (EEG) discharges in deaf children with psychological disorders are so limited. The primary focus of this study was to determine the prevalence of epileptiform discharges (EDs) in children with SNHL and overactivity or behavioral problems.
Materials & Methods:
A total of 262 patients with prelingually profound SNHL who were referred to our cochlear implantation center between 2008 and 2010 were enrolled in this study. Children with SNHL who had diagnosis of overactivity and/or behavioral problems by a pediatric psychiatrist, underwent electroencephalography (EEG). EEG analysis was carried out by a board-certified pediatric neurologist. The control group consisted of 45 cases with overactivity or behavioral problems and normal hearing.
Results:
One hundred thirty-eight children with mean age of 3.5±1.23 year were enrolled in the case group, of whom 88 cases (63.7%) were boy. The control group consisted of 45 cases with mean age of 3.2±1.53 years, of whom 30 (66.6%) cases were male. EDs were detected in 28 (20.02%) children of the case group (with SNHL) in comparison with 4 (8.88%) in the control group (without SNHL), which was statistically significantly different.
Conclusion:
In this study, we obtained higher frequency of EDs in deaf children with overactivity and/or behavioral problem compared to the children without SNHL. Further studies are required to evaluate the possible association of SNHL with EDs in overactive children.
