You say she was referred to a "specialist"--what specialty?  Neurology?
Internal Medicine?

One cause of something like what you seem to be describing involves
perturbations in the region served by the vertebro-basilar arterial
system, perhaps TIAs: called "drop attacks" they are characterized by
sudden unexplained loss of support by legs, without any awareness of
difficulty with them, without loss of consciousness, etc.

Some branches of this system supply brainstem nuclei relevant to
control of speech apparatus, so TIA (tansient ischemic attack) could
also include problems of articulation, if this is what you mean by
"problems with speech".

Anterior branches supply medial temporal lobe, so sporadic memory
lapses possible also (although not necessarily the best explanation,
has been suggested as basis for "transient global amnesia").

Some risk factors for TIA suggested in description: edema suggesting
cardiovascular problems, etc.

In older people, arthritic changes in cervical area may compromise
vertebro-basilar function, possibly marginal to begin with on basis of
vascular anatomy (great interindividual variability in anastomoses and
compensatory distribution) and/or arteriosclerotic narrowing of
vessels.
