[edit] Presentation
Children with this disease present with refractory seizure disorder, ataxia, and developmental delay with deceleration of head growth and microcephaly. The seizures are infantile, onset often beginning at 1-4 months of age, usually as complex seizures and later in childhood becoming more generalized. The frequency of seizures is variable and a history of decreasing seizure frequency during times of ketosis (ex: during an illness) may prompt the diagnosis.
Developmental delay is global and includes receptive and expressive language dysfunction.
[edit] Diagnosis
CSF glucose value, (<2.2 mmol/L), or lowered CSF/plasma glucose ratio( <0.4), erythrocyte 3-O-methyl-d-glucose uptake assay.
[edit] Treatment
Ketogenic diet helps control the seizure by providing ketones as an alternative fuel to the brain instead of glucose.[1]
