Clinical, EEG, electromyographic and polysomnographic studies in restless legs syndrome caused by magnesium deficiency.

The present paper reports biochemical and neurophysiological investigations in ten cases with restless leg syndrome. Other neuropsychiatric affections and factors which could generate the symptomatology of restless legs syndrome were not included. The EEG recordings demonstrated evident reticular neuronal hypersynchrony generated by hyperpnoea (sinusoidal slow waves).
