Hi,

An interesting note:   Alzheimer patients often develop a definite "sweet
tooth" and seem to crave sweets.   My mother in law developed diabetes after
she was here a couple of years already, and was put on medication.   In fact
had an awful time with the daycare center who was giving her tons of juice,
cakes, candy, etc.   It kept her up all night long peeing every hour on the
hour, until we finally got her diagnosed and medicated for the diabetes, and
controlled her carbohydrate intake.

I think that there probably is a connection, but not sure which came first,
'the chicken or the egg!'  Some of the medications used for delusions have a
side effect of increasing blood glucose.   It is a complicated subject and
some of these theories about what causes which, can be oversimplifications.
Although there is a connection, it is hard to definitively conclude that one
thing causes the other.
