Long-term cognitive outcomes in tuberous sclerosis complex.

Using point change in IQ as a dimensional measure, there was a significant correlation with age at seizure onset ( ρ =−0.33, p =0.003), severity scores for non‐spasm seizures in years 1 ( ρ =0.42, p <0.001) and 2 ( ρ =0.25, p =0.02), and a trend approaching significance towards increased tuber load ( ρ =0.22, p =0.05).
