Patients with subarachnoid neurocysticercosis (NCC) are usually older than those with parenchymal disease. Whether this difference reflects a prolonged presymptomatic period or a delay in diagnosis is not clear. From 408 eligible patients, we retrospectively compared the age at symptom onset in 140 patients diagnosed with parenchymal (pure viable or pure calcified) and subarachnoid NCC who had a confirmatory image available not more than 2 years after the beginning of symptoms. Patients with mixed (parenchymal and subarachnoid) NCC or those with parenchymal cysts at different stages (viable and/or degenerating and/or calcified) were not included. After controlling by sex and residence in rural endemic regions, the mean age at symptom onset in patients with subarachnoid disease was 13.69 years older than those with viable parenchymal disease. A long incubation period is a major contributing factor to older age at presentation in subarachnoid NCC, independent of delayed diagnosis or access to care.
