Thyrotoxic periodic paralysis in a Maori patient.

A case of thyrotoxic periodic paralysis (TPP) in a patient of Maori heritage is described. The epidemiology, aetiology and pathogenesis of TPP are discussed. The case demonstrates that neurological examination and biochemical findings may be normal between episodes of paralysis. Given that there is much racial variation in the prevalence of TPP, and the suggestion that non-thyrotoxic periodic paralysis may be more prevalent in Maori, the case highlights the need for more research into the prevalence and pathogenesis of TPP in Maori patients.
