Star Trek

I was doing a crossword puzzle on TNG on another site that I visit.  One of the clues was about Jean Luc Picard.  It asked what childhood syndorme he had.  I have checked some of my books but they only mention his heart problem that he had after a fight.  Anyone knows, I'd appreciate it.  (No latinum for the answer.)  Plus if you could tell the episode when it was mentioned that would be nice.    
Thanks

Plus if anyone wants to post another trivia question for others to answer, we could keep this going. The next person with the answer gets to post a question and so on.
Have fun.

Picard developed a hyper-sensitivity to sound and was diagnosed with Shalaft's Syndrome. It is mentioned in the movie Nemesis. Shinzon had the same condition and brought it up during their first conversation aboard the Scimitar.

Thanks very much to quantumstring12.  I guess that would answer the question why it was not in my books.  
They were printed before this movie.    
It looks like I need to update my library.
Have a great day in your sector of the cosmos.  

Your welcome.
