Thyrotoxic periodic paralysis in a Jamaican male patient

A case of thyrotoxic periodic paralysis occurring in a Black Jamaican male patient is described. Diagnosis is based on history and confirmed by evaluation of serum electrolyte during attacks and thyroid function studies. The pathophysiology, associations, therapy and prognosis are discussed. It is important that clinicians recognise the condition as all forms of periodic paralysis are amenable to treatment, and progressive weakness can be prevented or even reversed.
