Summary
Hypocalcemia can cause cognitive decline and seizures by increasing neural excitability. Prompt correction of calcium levels reversed these neurological symptoms, avoiding unnecessary antiepileptic drug use.
Area of Science:
- Neurology
- Endocrinology
- Clinical Neurophysiology
Background:
- Hypocalcemia, a condition of low serum calcium, can manifest with diverse neurological symptoms.
- Neuromuscular hyperexcitability, indicated by Chvostek's and Trousseau's signs, is a known peripheral manifestation.
- Central nervous system effects of hypocalcemia, such as seizures and cognitive decline, require further elucidation.
