title: [The EEG in hypercalcemia (author's transl)].
abstract: The EEG of 20 patients with hypercalcemia of different aetiology were investigated. (Hyperparthyreodism n = 14; Carcinomas with metastases n = 5; plasmocytom n = 1). General abnormalities were observed in most cases in different severity with a decrease of frequencies (n = 13) and an abnormal periodicity (n = 9). Beside one case there was a positive correlation between serum-calcium-level and EEG-abnormalities. Abnormal EEG-findings were observed mostly above serum calcium levels of 6,5 mval/1 = 13 mg%. There was a marked normalisation of EEG with decreasing serum-cacium-level. Different factors dealing with these abnormal EEG findings in hypercalcaemia were discussed.
