Not unless they develop one. But the problem is who will recognize they have a problem and take it?
I think that is the hardest part about all this. It is so obviously an illness, so obvious they are just going through the script and checking all the boxes, and they are suffering so much, and they have NO CLUE. If my husband had any physical illness and I went online and researched it for him and got him info, he would appreciate it. If I told him he has MLC illness, he would get angry. I can really understand what it must be like to have a relative with Alzheimer's. It's just so horrible and you cannot do a thing! Any other illness if you feel compassion for their suffering, they can feel it, but this, they can't. They don't know what we are bearing for them, just waiting for them to get better. They probably wonder why do we put up with their horrible behavior? They just have no clue why!
I think all of you who have children who might be at risk repeating this in the next generation, as soon as they are old enough, you should sit them down in front of this site and HB's site and make them read read read. Just so they know if and when it hits them, what it is.
