The Electroencephalogram in Hypercalcemia

The Electroencephalogram in Hypercalcemia Abstract THE PURPOSE of this study was to determine what changes, if any, are produced in the electroencephalogram by a rise in the serum level of calcium.1 A low level of serum calcium is usually considered to be associated with a state of hyperexcitability of the central nervous system (CNS) with resultant tetany. Schulte and Lohmann2 in 1962 described the EEG and electromyogram in experimental hypocalcemia. Conversely, although it has been less frequently described clinically or experimentally, a rise in the serum calcium is associated with depression of cerebral function. This depressing effect of calcium on the CNS was demonstrated by Gerard and Magoun3 in 1936.
