Sorry. I got tired of typing on my phone, which is the only device that gets a signal where we are now (phone is 4g, much better than 3G, plus it pulls in an extra bar or 2 of signal.There really are no known steps you go through. PPA has been little studied, mostly by a single doctor at Northwestern U who's currently doing a 10-year longitudinal study to determine things like the answer to your question. They are in year 6 now. My husband might participate, but that involves a couple of trips to Chicago, which we can't do right now.All we can expect is gradual loss of language, mostly output at first, but input problems have started too. There's an $8,000 machine they can help with output. Something to consider down the road. His particular type of PPA includes Parkinson's in the late stages. The brain atrophy is in the frontal and temporal lobes only, which is why only particular functions are affected, unlike ALZ which I think affects the whole brain. One thing known a out PPA is that it strikes about age 60 or a little earlier. Again unlike ALZ, which can strike at any age from the 40s to 90s. PPA is thought to be genetic. Nothing DH did or didn't do caused this terrible fate.On a more cheerful note, DD will have her baby today or tomorrow. She's overdue so they are trying to induce right now. If that doesn't result in a vaginal birth today, shel have another caesarean late today or tomorrow. We'll be up there to see everyone Saturday morning.
