Aspergers isn't a separate diagnosis any more (under the DSM-V, 2013); it is part of the ASD spectrum (which means the diagnosis is "ASD" or Autistic Spectrum Disorder).
ADHD, ADD, dyslexia, dyscalculia, dyspraxia and depression also fall somewhere on their respective spectrums, however expression amongst individuals varies considerably so two prospective applicants could both have Aspergers but have a completely different mix of difficulties.
Also, all of these overlap with each other to some degree so sometimes, it is difficult to make a specific diagnosis. Only a psychiatrist can make a proper, accurate diagnosis
And remember, Richard Branson had dyslexia...
