[Results of polygraphic nocturnal sleep recording in patients with supratentorial brain tumors prior to and following surgery].
The purpose of the study was to establish the influence exerted by a supratentorial brain tumour on the EEG correlates of sleep, and to compare the results before and after operation. Five patients were studied (aged 38 to 59 years) who were treated surgically for supratentorial expanding lesions: two cases of meningioma (in left parietal area), two cases of glioma (right parietal area and occipital area) and one case of intracerebral haematoma. The control group comprised 5 patients operated upon for lesions of the peripheral nerves of extremities. In the patients with supratentorial brain tumours and after their removal the following sleep parameters were unchanged: total sleep duration, number of awakening during sleep, latency time of the first REM phase and stage 3 NREM (deep and superficial sleep). The amount of REM sleep increased after tumour removal. REM-sleep density was selectively and permanently disturbed. In presence of tumour REM-sleep density was found in traces only, after tumour removal it increased but showed a permanent high-grade deficit in relation to controls.
