I believe high blood pressure, high blood sugar,
and a persistent dizziness are symptoms with the
same cause which appeared at about the same time
or even earlier in my mother. I don't know whether
these are generally recognized to be related
conditions by medical science.
It's not quite simple forgetfulness. It's impaired
ability to form new long-term memories, like
remembering in the afternoon what happened in the
morning or on the previous day. Remembering events
from 70 years ago is not much impaired at all.
