Abstract

Highlights: Time from onset to diagnosis is similar in T21 and idiopathic infantile spasms (IS). Time from treatment to resolution is similar in T21 and idiopathic IS. T21 related IS are less likely to develop epilepsy than idiopathic IS. Abstract: Purpose: To determine if there are differences in the timing of diagnosis and response to treatment between infants with infantile spasms (IS) and Trisomy 21 (T21) and those with idiopathic IS. Method: This was a retrospective study evaluating the time from onset of IS to diagnosis, treatment of IS, time from treatment to resolution of IS, and development of epilepsy in children with T21 and IS compared to children with idiopathic IS. Results: Thirteen children with T21 and IS were identified over a 10 year period and compared to 32 children in the control group. There was no significant difference in age of onset, time between onset and diagnosis, or acute response to treatment. However, the children with idiopathic IS were more likely to go on to develop epilepsy than those with T21 and IS (41% vs. 0, p = 0.006). Conclusion: The children with T21 and IS were diagnosed and treated similarly to those patients with idiopathic IS. There were no significant differences in the age of onset, time between the onset and diagnosis of IS, or acute treatment response of IS between the T21 and control groups. However those with T21 and IS had a lower risk of subsequent epilepsy following IS than those with idiopathic IS. IS in the T21 population appears to be inherently different from IS of unknown etiology.
