[Uremic encephalopathy and oligo-elements]

The author reports the probable pathogenetic connexions between oligo-elements and uremic encephalopathy. Acquired data concerning this rare pathology of the CNS are reported as well as those of more doubtful scientific validity. The behavior of the neuro-psychic sphere and the symptomatology deriving from both deficit and excess of Al, As, Mg, Cr, Mn, Se, etc. are subject to special attention. The result of these changes is a complex of syndromes that are difficult to identify, also because uremia is beset by a large number of complications which more or less directly involve the central and peripheral nervous system.
