Robert (and Chris) I was puzzled by Chris's comment too, as I did not see any study sited in this thread.
Someone had brought up a study having to do with peripheral nerves and sensory conduction while back, and I remember Wright taking the time to explain that the comment made was taken completely out of context.
Just speaking from my standpoint, I'll reiterate that no doctor has ever asked me if I was experiencing fasciculations or twitching. It is not part of the diagnostic process in eliminating or concluding that a person has ALS, and the El Escorial states that conduction block (I guess this is a slowed NCV?) is criteria that points away from an ALS diagnosis, and toward other causes.
I recently was researching the Jpeg that my gastro doctor has said that although it is not time yet, I will need (trying to differentiate between jpeg and the PEG that most on PALS on here have) and I ran across a report on a 42 yr old man that had severe balance issues, marked muscle atrophy, and something else.... just can't remember. but anyway, because of the slowed NCV the doctors were able to realize they were looking at someone that had problems from severe neuopathy brought on by so many incidences of being dehydrated. According to this study, the man developed terminal renal failure from the dehydration. But, of course, what I found was so interesting, was, not only was he never considered a "candidate" for ALS, but that the cause of his neurological problems were something as simple as not being able to stay hydrated adequately. I believe he had the jpeg because of complications from diabetes. Advanced diabetes often causes various levels of gastroparesis, and as I have gastroparesis, I've become resigned to most information I can obtain on it being written for diabetics.
Once again, this is another great example why we need our doctors to sort things out, rather than Dr Google......
Another observation is that we are not islands unto ourselves (not original, but true nevertheless) For those that remain fixated on ALS, even though they've been told by their doctors, etc, that this is not the case, it might be good to remember that those that love them are eventually going to tire of the whole obsession. Its hard enough making things work when everyone is happy, healthy, & employed, etc... if the focus remains on the unlikely, eventually relationships are bound to suffer. Even for those of us that have a diagnosis, having that diagnosis does not mean that every conversation, and all down time needs to be spent on ALS and its ramifications, life goes on, others in our circle of friends and families have things going on that they need to know matter as well.
I, for one, intend to get more out of my daily living than dwelling on what is wrong with me, and what is or might be in store for me in the future.
Every day is a gift.
