NO, Kccheng, NOT "an obvious case of nonfatal strokes". Read the
description carefully: Peter describes SPORADIC problems, raising the
possibility of transient ischemic attacks (TIAs), which may or may not
proceed to full strokes, i.e. with permanent damage which could perhaps
bne seen on MRI. Read my prior response to this query in which I
describe some aspects of vertebro-basilar insufficiency, which
classically can include "drop attacks".
IF these are TIAs, and IF one catches them in progress (possibly with a
provocation) one might be able to see circulatory alterations with
Doppler. re provocation: obviously one must be cautious (not wanting
brainstem infarct), but if there are known "naturalistic" conditions
which provoke these symptoms, they might allow identification of the
basis for them. For ex: provoked by postural hypotension (standing
froom sitting position)? Head turning? (with osteeoarthritic cervical
abnormalities, may sometimes compromise posterior circulation).
Conceivably, if chronically insufficient but short of actual stroke,
might be seen on SPECT?
