ABSTRACT

Objective:

To analyze the clinical characteristics of late-onset epileptic spasm (LOS), thus providing basis for its early identification and treatment.

Methods:

Clinical data[electroencephalogram(EEG), imaging, treatment and prognosis]of LOS patient hospitalized in the Department of Pediatrics, the Second Affiliated Hospital of Xi′an Jiaotong University from January 2017 to June 2019 were retrospectively analyzed.

Results:

The age of onset of spasm in 35 children with LOS ranged from 18 months to 11 years old, with a median of 42 months.There were 21 cases of symptomatic LOS (60.0%) and 14 cases of cryptogenic LOS (40.0%). Epileptic spastic seizures, generalized seizures, partial seizures and myoclonic seizures as the first onset were reported in 13 cases (37.1%), 11 cases (31.4%), 10 cases (28.6%), and 1 case (2.9%), respectively.There were 15 cases (43.9%) of flexion type, 11 cases (30.4%) of extension type and 9 cases (25.7%) of mixed type.Spastic seizures can be presented as genera-lized or focal seizures.Among the 35 cases of LOS, 12 cases (34.3%) had normal EEG background, 18 cases (51.4%) had slow EEG background, and 5 cases (14.3%) had high EEG irregularity.Three cases were in accor-dance with Lennox-Gastaut syndrome and the other 32 cases were not in accordance with the defined epileptic syndrome.Eighteen cases were treated with antiepileptic drugs, and sodium channel blockers were added in 9 cases; 17 cases were treated with glucocorticoid.Eight cases did not have seizures at the last follow-up.There were 17 children with seizure reduction ≥ 50%, 3 cases with seizure reduction < 50%, and 7 cases with no reduction of seizure.

Conclusions:

LOS is mostly symptomatic and often associated with other types of seizures.Most of cases do not have high irregularity in the EEG, and the focal discharges are mainly in the temporal region or frontotemporal region, with refractory epilepsy mainly.The onset age, etiology and EEG characteristics of LOS differ from those of West syndrome, which should be detected and treated as soon as possible to improve the prognosis in pediatric patients.
