A 5-year-old boy presented with frequent absences. Speech began to regress. He became ataxic, barely able to walk. Studies with Xe-133 and hexamethylpropylene amine oxime single-photon emission computed tomography revealed sharply decreased cerebral blood flow, especially in the occipital area. Landau-Kleffner syndrome was suspected but a sleep electroencephalogram showed few abnormalities. He was started on clorazepate and diltiazem. A skin biopsy to rule out possible CLN2 revealed, instead of the predicted curvilinear profiles, granular osmiophilic deposits, consistent with infantile neuronal ceroid lipofuscinosis (CLN1). The family reported increased seizure frequency and consulted with a colleague, who advised them to resume valproate and discontinue diltiazem. The boy died shortly thereafter. Decreased cerebral blood flow is a new finding in CLN1 with delayed onset. Calcium-channel blockers improve cerebral blood flow and perhaps delay clinical regression.
