Insights
Pediatric psychogenic nonepileptic seizures (PNES) pose a diagnostic challenge. Earlier seizure onset and a history of psychological abuse are linked to delayed diagnosis in children with PNES.
Area of Science:
- Neurology
- Child Psychiatry
- Epilepsy Research
Background:
- Psychogenic nonepileptic seizures (PNES) in children present diagnostic difficulties.
- Delayed diagnosis impacts treatment and outcomes for pediatric PNES patients.
Purpose of the Study:
- To analyze diagnostic delays in pediatric PNES.
- To identify risk factors contributing to delayed PNES diagnosis in children.
Main Methods:
- Video electroencephalography (EEG) documented PNES in 53 pediatric patients.
- Neurological and psychiatric interviews were conducted.
- Patients had no prior PNES diagnosis.
Main Results:
- Average delay from seizure onset to referral was 17.76 months.
- Earlier age of seizure onset correlated with a later diagnosis (P < 0.001).
- History of psychological abuse was associated with delayed referral (P = 0.018).
Conclusions:
- Pediatric PNES diagnosis is challenging.
- Identifying at-risk children can facilitate earlier PNES diagnosis and intervention.
Background:
This study aims to analyze a series of pediatric patients with psychogenic nonepileptic seizures (PNES) to establish the diagnostic gap and possible risk factors for the delayed diagnosis in this age group.
Methods:
We evaluated all children with PNES documented by video electroencephalography. None had a previous diagnosis of PNES. In total, we included 53 children (interquartile range: seven to 17 years; mean age 12.81 years [S.D. 3.15]; 60.4% girls) who underwent a protocol consisting of neurological and psychiatric interviews.
Results:
The average time between seizure onset and referral was 17.76 months (interquartile range: 0.5 to 48 months; S.D. ± 12.62). Earlier age of onset correlated with a later diagnosis (P < 0.001). The late referral group also presented with a history of psychological abuse (P = 0.018).
Conclusion:
Youth with PNES represent a diagnostic challenge. Identification of children at risk might lead to earlier diagnosis of PNES.
