ALS
Hi Diza, re: your edit on amyotrophic lateral sclerosis I just wanted to let you know that this is a discussion that's been had before. The logic in calling it ""fatal"" is that for the vast, vast majority of patients it is unfortunately a rapidly progressive disease. Although about 5% or so survive past 10 years most do not. I would certainly agree that primary lateral sclerosis or even progressive muscular atrophy could be considered chronic rather than fatal, although the latter is also life-limiting. As a counter-example I would say Parkinson's disease is chronic rather than fatal, even though statistically people with the disease do live for a shorter time than those who do not have it. Interested in your view.  "
