I have mentioned to people, the number of similarities between MS/Multiple Sclerosis and ALS/Amyotrphic Lateral Sclerosis/Lou Gehrig's and this article on the about.com site, discusses at some length some of those similarities, as well as the differences between the two neurological diseases.

There was a time, early on when we were trying to pin down the diagnoses to my health issues.....that I was not to the point of thinking much about having ALS,,,,,and thought seriously, that perhaps my problems were centered around MS........or Myasthenia Gravis perhaps.

I hated that thought....thinking that not much could be worse than either the MS or MG until the final diagnoses by two separate medical centers (OSU & Cleveland Clinic) who both confirmed the ALS....
then, 
I was sorry it was not a diagnoses of MS or MG  instead.....

...and since the diagnoses of the ALS, upon further reading of  neurological diseases in general  and more specifically about MS for which there is more information about such as on the about.com site.....
I still see a large number of similar symptoms that gives me reason to read and contemplate the shared information about those symptoms for support in dealing with these issues...............
this thought may be helpful to others of you out there in the same situation.
