Modified ketogenic diet (MKD) therapies reduce seizure frequency and severity and improve quality of life (QOL) among adults with drug-resistant epilepsy (DRE) with few side effects outside of weight loss, a desired outcome among many adults with DRE, according to a recent study. Changes in seizure frequency, severity, QOL, and side effects were retrospectively examined among adults, aged ≥17 years, with DRE (≥2 antiepileptic drugs [AEDs]), after 3 months of MKD therapy. Attention was paid to medication or vagus nerve stimulator (VNS) changes as well to evaluate potential confounders. They found:
- A total of 60% (n=33) of the 55 individuals reported ≥50% seizure frequency improvement, 42 (76%) reported improvement in seizure severity, and 48 (87%) reported improvement in QOL.
- More patients following a modified ketogenic diet—15 g net carbohydrate daily (MKD-15) (95%) compared with a MKD-50 (69%)—reported improvement in QOL.
- Weight among the entire sample declined from 77.5 (20) kg to 73.9 (19.0) kg.
