✦ Synopsis

Nine dialysis patients with significantly increased serum-aluminum levels due to chronic ingestion of aluminum hydroxide gels and eleven dialysis patients with normal serum-aluminum levels were tested neuropsychologically for generalized functions (intelligence, reasoning, memory) and for more specific abilities (visual memory, verbal and reading fluency, manual dexterity). All tests did not reveal any significant difference in neurophyscholigical functioning between the two groups. This finding seems to indicate that oral aluminum is not neurotoxic for man, even under circumstances of renal failure. This contradicts the idea that oral aluminum plays a role in etiology of dialysis dementia. However, the possibility cannot be excluded that aluminum overload in the present sample was not sufficient to induce changes in CNS functioning. Thus, until the importance of oral aluminum has been decided, it seems wise to keep all sorces of aluminum overload as low as possible.
