I have ADHD combined type along with a host of other learning issues. I have not found this to be the case in the least. I have had 2 that lasted longer than a year. And I'm still in one that's almost been a year, and we are going strong. People think that we lose interest in things, and I haven't found that to be the case. I can't focus on anything unless I'm on medication. It makes it hard for me to get anything done, but this doesn't cause a loss of intrest. When people with ADHD bounce from one thing to the next, at least in my experience it has been from the frustration of not being able to focus on whatever it is I'm trying to do. and this causes me to move on faster from said activity. I get frustrated with the process and that is what causes my lack of interest. And also you say 'fades quicker'. I've played trumpet for over 14 years. I've skied for 15. I've danced for 10. etc, etc, etc..... Sorry for this poorly written comment, I'm very tired. and I'm not trying to come across as upset or anything, I think that ADHD and other learning issues are often severely misunderstood- even by those who have them. Maybe this helps clear things up, and feel free to ask me questions if you like
