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. They showed in cats that the response following stimulation by an intracerebral electrode would be decreased immediately after the intracarotid injection of calcium chloride.

Lehrer and Levitt⁴ in 1960 mentioned the EEG findings in two patients who had elevated serum . . . [Full Text PDF of this Article]
