Purpose:
Epilepsy is a comorbidity of idiopathic autism spectrum disorder. The aim was to characterize the risk and time of second seizure in children with idiopathic autism spectrum disorder.
Methods:
A retrospective review was performed at the University of Chicago and NorthShore University HealthSystem. Patients with idiopathic autism spectrum disorder, ≥1 seizure, and age 2 to 23 years were included.
Results:
153 patients were included; 141 (92%) had a second seizure. The average age at first seizure was 7.14 years (median: 5.08 years) and 8.12 years (median: 7.3 years) at second seizure. Average time between first and second seizure was 7.68 months.
Discussion:
A high risk of seizure recurrence was found in this population. There was a short time to second seizure, with most having a recurrence within 1 year. These findings may be used to guide therapy in children with autism spectrum disorder and epilepsy.

Autism Spectrum Disorder
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
