[The EEG in hypercalcemia]

When a patient with hypercalcemia presents symptoms of encephalopathy, then also the EEG shows some abnormal characteristics; triphasic waves are mentioned. Both the clinical and electroencephalographical disturbances are grave, nevertheless they are specific. As well the clinical as the electroencephalographic symptoms have a tendency to disappear when the calcemia bends to normal values; there exists a certain latency. The reason for hypercalcemia usually cannot be properly cured, so an encephalopathy due to hypercalcemia mostly includes bad prognosis.
