Here are some comments on your PDF file.
1. The first page contains a title only (as shown on my PDF viewer). That seems unnecessary.
2. On the first page, the text starts with "ALS was founded in 1869". I suspect you meant some other word besides "founded", such as identified.
3. On page 4, in the first paragraph, "This could make the breathing difficulty worsen and cause", "worsen" should be worse (make ... worse vs make ... worsen).
4. On page 4, in the first paragraph, "Calls received from the individual with ALS, they can communicate" would be better stated as "People with ALS communicate in "
Thanks for putting this together.
