I believe the Seattle Temple held a session for members with tourettes syndrome. I understand it was a very unorthodox session with a lot of otherwise inappropriate outburst
One of those things I never thought of, but would have great impact on an individual. It is one thing to attend SM where people are familiar and accepting of one's condition, but to be in the temple in a crowd of mostly strangers and not being able to control oneself....that would discourage me from attending. What a great idea to have a special session for as much comfort as possible. I can see also making an announcement to the attendees not to be troubled if something happens during a session due to someone's disability, but who wants to be focused on like that?
When you climb up a ladder, you...begin at the bottom...ascend step by step, until you arrive at the top...so it is with the principles of the Gospel--you must begin with the first...go on until you learn all the principles of exaltation. But it will be a great while after you have passed through the veil before you will have learned them. It is not all to be comprehended in this world. Joseph Smith
