Welcome Yvonne,
My 12-year old special needs son has Lennox Gastaut syndrome. He had his first seizures at age 1,5 and his epilepsy worsened very fast. LGS was diagnosed at age 3. His EEG showed 90-99% epileptic activity in the typical LGS slow wave pattern on the background. He suffered all types of seizures and had many seizures each day and night untill he was 5. We have tried over 10 medications without any succes, just many side effects.
At age 5 we started him on the classical ketogenic diet. We did not expect this diet to work but it did. It was a miracle, in the first week on the diet his seizures reduced significantly. After 6 months of finetuning the diet (not an easy thing to deal with) his EEG was improved >70% and he became seizure free for long periods. We managed to wean off all AEDs and benzo's.
He is on the ketogenic diet for over 7 years now. He is not 100% seizure free, I guess he never will be, as soon as he is ill or his blood ketosis is to low, we see seizures breaking through the diet. But those are only short incidental periods, we know how to manipilate his ketosis with the diet and when not he is not ill we don't see seizures as long as the diet maintains sufficient ketosis
The ketogenc diet had made THE difference for my son. He is and will be disabled but he is a happy boy now and doesn't suffer from constant seizures as he did before. The significant seizure reduction helped him to develop a little more instead of the retardation we saw before the diet.
Here you can read my son's story, I wrote this 5 years ago for Matthews Friends.

The diet is effective in about 50-60% of kids with LGS which is a far better chance than medication for this syndrome.
