Neurocysticercosis: an under-recognized cause of neurological problems.

Neurocysticercosis is an uncommon, and under-recognized condition in Australia. Changes in immigration patterns may lead to a rising prevalence in this country. Epilepsy is the most common presentation, but it has many other variable forms of neurological manifestations. Eight cases are described, all in immigrants from Eastern Europe, Asia or Central America; the disease was presumably acquired before arrival in Australia. Six patients had symptoms for two to 30 years before the diagnosis was made and, in some cases, the first neurological manifestations appeared decades after initial infection. In patients with active disease a successful outcome followed therapy with praziquantel and corticosteroids. We advise that all patients requiring treatment be admitted to hospital for corticosteroid and anticonvulsant therapy to minimize the clinical deterioration which may result from therapeutic destruction of larvae.
