While Rourke’s neuropsychological model of NLD has weathered several years of increasing knowledge about the brain and its components, the model has yet to be empirically investigated. The NLD syndrome at this point remains a theoretical construct because the presence of white matter dysfunction has never been demonstrated among children or adults identified as having this disability (Filley, 2001).

Perhaps explicit empirical testing of the neuropsychological model will improve understanding of this disorder among professionals who are responsible for diagnosing this still-mysterious syndrome.
