Perampanel-induced weight gain depends

IQ ≥35 n = 31) and severe to profound ID (IQ <35 n = 21) groups. BW was measured before and 2 4 6 and 12 months after initiation of PER treatment and serum PER concentration at 12 months. The mild to moderate ID group gained more BW than the no ID group suggesting that PER-induced food intake was greater due to weaker behavioral control in the mild to moderate ID group. The present study suggests a linear correlation between serum PER concentration and BW change.
