GH1 and Dravet syndrome: GH releasing effect was studied in 12 DS patients showing that the response to hexarelin is normal and is similar to GHRH plus pyridostigmine, slightly higher than GHRH alone, and much higher than clonidine, levodopa, and insulin stimulation tests (22), with p-value of <0.0001, 0.000192, and 0.077, respectively.
