Vitamin D deficiency presenting as seizures

Abstract

Vitamin D deficiency is commonly seen in the general population, likely due to lack of adequate exposure to sunlight as well as lack of sufficient dietary intake. However, severe hypocalcemia secondary to vitamin D deficiency, manifesting as seizures is uncommon. We present a series of such cases encountered by us in the time frame of June 2020 to Dec 2021 (the first wave of the Covid-19 pandemic associated with a lockdown) during which patients of varying age groups presented with seizures. The only abnormality detected was severe hypocalcemia due to vitamin D deficiency and they all responded well to calcium and vitamin D replacement, without recurrence of seizures or hypocalcemia.
