Hi, rjmx ... I may as well pile on ... and answer your one question again ... several others have as well, so you should be all set.
I've got one dynamic scene in mind and if I could link that with my character's ALS, it would be extremely compelling. If a patient came down with pneumonia or a cold and that, coupled with the weakness of breath associated with ALS, made it so hard to breath that he needed an inhaler or oxygen to stay alive, would that be plausible?
No ... it is not plausible. That is not how ALS works, as others have explained. ALS affects muscles not organs. Any ALS patient with seriously impaired breathing would a) have a BiPap breathing assistance with them at all times, and b) NOT be traveling. If they developed pneumonia, they'd be in a hospital or ER. If the BiPap weren't sufficient, a tracheotomy would be necessary. There would be no "sudden breathing emergency" from a confluence of events in an airport.
If you need a disease with sudden respiratory failure, try Myasthenia Gravis (although again, the use of an inhaler or oxygen would not be the solution ... hospitalization and entubation would be necessary.) Also, MG respiratory failure is not that "sudden," it comes on more slowly than your dramatic needs would allow.
Best bet is to give your "victim" a heart attack. Or asthma.
"Raising awareness" of ALS is counterproductive if you don't understand the nature of the disease.
Just a simple request in exchange for all this wonderful information we are giving you: If you do ever complete your screenplay, dynamite death scene of ALS patient and all, and some producer snaps it up, and it gets greenlighted, and funded, and made into a major motion picture (I'm seeing Tom Hanks as your PALS), PLEASE DONT MENTION TWITCHES . Living in LA as you do, I'm sure you are familiar with how often wanna-be screenwriters hit gold on their first get-go, so I'm sure this will be in theaters by 2011. :lol:
Thank you for your cooperation on the twitches.
