To be accurate (as this non-medical person recalls it), "Alzheimers" is for when unusually young (age 50-60) people experience the symptoms of senile dementia.

When octagenarians experience it, it is just senile dementia. But our society has euphemized the term to apply to all who have those symptoms.
