The
relationship between performance on cognitive tasks
|
|
|
and
circulating levels of lead in blood and accumulated
|
|
|
levels of
lead in bone was examined in 141 middle-aged and
|
|
|
elderly men.
Men with higher levels of blood and bone
|
|
|
(tibia)
lead copied spatial figures less accurately; men with
|
|
|
higher
levels of bone (tibia) lead had slower responses for
|
|
|
pattern
memory. These findings
suggest that low levels of
|
|
|
lead contribute to impairments in cognitive function among
|
|
elderly men.
