title: Approach to neurometabolic diseases from a pediatric neurological point of view.
abstract: Objective Neurometabolic disorders are an important group of diseases that mostly are presented in newborns and infants. Neurological manifestations are the prominent signs and symptoms in this group of diseases. Seizures are a common sign and are often refractory to antiepileptic drugs in untreated neurometabolic patients. The onset of symptoms for neurometabolic disorders appears after an interval of normal or near normal growth and development.Additionally, affected children may fare well until a catabolic crisis occurs. Patients with neurometabolic disorders during metabolic decompensation have severe clinical presentation, which include poor feeding, vomiting, lethargy, seizures, and loss of consciousness. This symptom is often fatal but severe neurological insult and regression in neurodevelopmental milestones can result as a prominent sign in patients who survived. Acute symptoms should be immediately treated regardless of the cause. A number of patients with neurometabolic disorders respond favorably and, in some instances, dramatically respond to treatment. Early detection and early intervention is invaluable in some patients to prevent catabolism and normal or near normal neurodevelopmental milestones. This paper discusses neurometabolic disorders, approaches to this group of diseases (from the view of a pediatric neurologist), clinical and neurological manifestations, neuroimaging and electroencephalography findings, early detection, and early treatment.
