In older patients, exercise intolerance, hypoglycemia, and seizures often developed. Common features in both groups of patients are macrocephaly, expansion of subarachnoid convexity spaces, and wide CSF spaces anterior to the temporal poles and in the Sylvian fissures.
Molecular analysis, including gene sequencing and copy number analysis of GCDH can be performed to confirm the diagnosis. In 10 patients, the disorder was first manifest between 3 and 18 months during an acute infectious illness. Hence, the initial presentation may resemble viral encephalitis or ADEM.
