D) "Alzheimer's appears to result from a combination of genetic and environmental factors and no one theory can explain it.".
D
Feedback:
The current understanding of the etiology of Alzheimer's disease is incomplete, but not wholly lacking. The disease appears to be a result of the interplay of genetic and environmental factors. It is not completely attributable to diet and removal of risk factors and contributors does not normally bring about an improvement or recovery.
