The bottom line is that it's up to the sufferer of the syndrome to make himself known, and they are aware of that, they are also well versed in the problems associated with their particular syndrome.
An ADHD for instance "sufferer" will look just that same as any other person, we are not to know they have a problem, and will treat them the same as any other person.
Quite frankly if the syndrome is severe enough to cause a social problem then it is down to the individual to decide whether he is fit to be part of the group, and if he can control himself sufficiently to be an active part of the group.
If he has decided that he can, then he should then inform the person in charge of the group of his issues. Not just walk around like a ticking time bomb waiting to be upset or offended or get a slap from an unwary person
I work with such types on a daily basis, and there is no need for things to get to the point that someone gets upset, and that means planning and communication, but that has to be initially on the part of the sufferer/ patient. WE are not mind readers
It might also be worth noting that this is just a social group, and to burden it with having to cater for every conceivable syndrome is asking too much. It could even push things over the edge.
Now you might see why I am uneasy about this thread.
Do we have to open a BushcraftUK Asperges section, followed then by....
I am sure you know what I mean.
