Which disorder is more handicapping, NLD(Nonverbal learning disability) or Down Syndrome?
The disorder that the person in question has. Each learning disorder comes with its own unique challenges, and, on top of that, each person is unique in his or her learning style, and even abilities from one subject to another. If you are an educator, you can study up on each syndrome and get a basic idea of what is common to children with each one. Then, armed with basic knowledge, you work with each child as an individual, discovering his or her unique gifts and working around the challenges each one faces.
