Clinical and Nutritional Effectiveness and Impact on the Quality of Life of the Ketogenic Diet in Pediatric Patients With Neurological, Genetic or Metabolic Disorders: a Multicenter Prospective Observational Study
The goal of this observational study is to learn about the clinical and nutritional effectiveness of ketogenic diet (KD) in pediatric patients with genetic, neurological or metabolic conditions requiring KD. The main question\[s\] it aims to answer are: * does KD support adequate growth? * does KD improve clinical symptoms? * how does KD impact quality of life? Participants will be followed up as per clinical practice
• Pediatric patients (aged \< 18 years) with drug-resistant epilepsy (fail to achieve (and maintain) seizure freedom with adequate trials of two or more antiseizure medications) or genetic, metabolic, neurological (congenital and acquired) diseases treated with ketogenic diet
• Pediatric patients (aged \< 18 years) with metabolic, genetic or neurological (congenital and acquired) diseases (not necessarily associated with drug-resistant epilepsy) treated with ketogenic diet; this includes the new KD indications or the administration of KD in the ICU for status epilepticus.
