What are some of the main medical, mental, social, or environmental challenges facing this person?A Russian woman of approximately 69 years,...

There are many challenges in this case study.  I would
suggest that there might be some level of early onset for Alzheimer's Disease.  The
description that scientists use to articulate it in the early stages is "insidious," in
that the onset of it is stealth and not entirely evident.  The fact that the woman was
able to prepare things for herself, and then suffered a moment or two where this became
difficult would indicate to me that Alzehimer's Disease is a challenge that might be
present.  The dementia that is often a part of the disease might be present in the need
to "visit someone" and then speaking in an incoherent manner.  It sounds like to me that
some tests to be able to detect if Alzheimer's is at play or where the woman is in her
stages of Alzehiemer's.  The age of the woman and the sex might be two indicators that
Alzheimer's is present. Casts of the disease are present in patients over 65 and women
at slightly higher risks than men would indicate as such.
