title: [Severe vitamin D deficiency causing hypocalcaemic seizures in an ethnic Danish teenager].
abstract: We describe an ethnic Danish teenage boy presenting with repeated non-febrile generalized hypocalcaemic seizures. During the previous two years he experienced fatigue, painful legs, increasing social isolation and failure to attend school. Severe hypocalcaemia was recognized at his second seizure. After treatment with vitamin D his symptoms resolved and he became increasingly social and outgoing. This case describes possible non-skeletal effects of severe vitamin D deficiency and underlines the necessity of measuring ionized calcium at the presentation of non-febrile seizures.
