PZ- I find it interesting that you describe your voice/speech as gravelly & not slurred.
That is the way I describe Jim's speech; and, not all the time- mainly when he is trying to project his voice (like in a crowd) or at night when tired. In fact, one of his early "complaints" was that he couldn't project his voice (he was a lecture at church)
He also had larnygospasms (occasionally) & a "funny" feeling in his throat. He was sent to an ENT who scoped him, then sent him for barium swallow which showed a hiatal hernia. The ENT then thought acid reflux (as these symptoms are similar).
Started Zantac & Prilosec; not much of a change. This was simultaneous with "changes" in right leg; fast forward to seeing als specialist, EMG etc.
Speech pathologist thought the larnygospasms might be due to bulbar issues. Neuro said he never saw bulbar start with that (since only LMN symptoms diplayed- no clinical evidence of UMN). But, did start Clonazepam & saw ENT familiar with ALS.
He scoped him & did a more through exam ("was able to see 90% of what I wanted") with much difficulty (hypergag reflex?) & saw slight weakness on right side of "false-cords". Again, mention of acid reflux vs. atrophy; would need EMG to determine cause.
BUT, interestingly, after starting the Clonazepam, his spasms stopped AND the yawning
(excessive/exaggerated) decreased! Which lead me to think they were UMN symptoms!
And, they are- pseudobulbar! Which are UMN in the bulbar regions.
So, I have no research or studies or trials or even the doc's say-so behind me;- but I'm thinking he has LMN dominant ALS! Just because he hasn't seen it, doesn't mean it doesn't exist!
I never "bought" the acid reflux thing- he just never had a problem before.
I'm thinking the "projection of voice", the laryngospasms, the gravelly speech is more an UMN problem all within the bulbar region. This is very slow progression, by the way.
This all started in Nov. 2006 (that we can recall); and to this day, not even his family have commented about his voice. (I realize, though, that they just don't want to upset us. I have never come out & asked them about this!)
DISCLAIMER: I am not a doctor; I have not been told this by a doctor; these are only my opinions, AND I have had 2 glasses of wine tonight!
