hi donna.
pls progression is wide and varid and can depend on many things like age of onset and if ever lmn involvement eventually manifests.
i do think the older onset patients bodies have a harder time dealing with the disease.
i know many in there 50's-70's who have had pls for 20+years and despite there disability are still active with use of walkers ect. some of these can still talk.
they say respitory problems dont manifest till later in the disease but in some that is not the case,though i think not as life threatning as in als(so not to scare you)
i have had pls 10yrs,started with leg onset and has progressed slowly up the body.
i developed bulbar symptoms about 3yrs or so ago.
despite bulbar problems i can still talk with the occasional slurred speech or words sounding garbled.
i can still walk a short distance with aids and try to stay active doing just the usual daily jobs around the home.
has it been 3-5yrs with symptoms before your dads diagnosed? emg ok?
ofton in the early years progression can seem fast and symptoms severe but usually things plateau.
please try not to worry too much.
from what i know of in the usa medicare will pay for any equipment through the alsa or mda.
i think the mda are better and can ofton loan equipment.
if you look up the nearest mda and call them i'm sure they can help.
