Epilepsy in childhood Down syndrome
Insights
Epilepsy affects 1.4% of children with Down syndrome, with infantile spasms being more common in this group. Seizure onset is most frequent within the first two years of life.
Area of Science:
- Neurology
- Pediatrics
- Genetics
Background:
- Down syndrome is a genetic disorder associated with various health complications.
- Epilepsy is a common neurological condition in the general pediatric population.
- Understanding epilepsy prevalence and characteristics in Down syndrome is crucial for early diagnosis and management.
Purpose of the Study:
- To determine the prevalence of epilepsy in a cohort of children with Down syndrome.
- To characterize the types of seizures and age of onset in children with Down syndrome and epilepsy.
- To compare epilepsy occurrence in Down syndrome with the general pediatric population.
Main Methods:
- Retrospective analysis of 844 children under 15 years of age diagnosed with Down syndrome.
- Documentation of epilepsy diagnosis, seizure types, and age of seizure onset.
- Statistical comparison with general population epilepsy data.
Main Results:
- 1.4% of children with Down syndrome in the study cohort had epilepsy.
- The most common seizure types were generalized tonic-clonic convulsions (46.1%) and infantile spasms (30.8%).
- Epilepsy onset was most frequent within the first two years of life (73.7%).
Conclusions:
- The overall occurrence of epilepsy in children with Down syndrome is similar to the general population.
- Infantile spasms are notably more prevalent in children with Down syndrome compared to the general population.
- Early-onset seizures are common in children with Down syndrome, highlighting the need for vigilant monitoring.
Abstract:
This report concerns 844 children with Down syndrome under 15 years of age. Of the 844 cases with Down syndrome, 1.4% have epilepsy at the present time. The types of seizures are as follows; infantile spasms in 4 cases (30.8%), generalized tonic-clonic convulsions in 6 (46.1%), Lennox-Gastaut syndrome in 1 (7.7%) and psychomotor seizure in 2 (15.4%). The onset of seizure was high in the first two years (73.7%). The occurrence of epilepsy in Down syndrome in childhood did not differ from that in the general population, but infantile spasms were prevalent in Down syndrome.
