That's very interesting. Would that mean that, unlike AS, NLD would be either genetic or acquired through trauma to the brain?
I haven't read any research about inherited NLD without some other genetic condition, although it certainly seems to run in my family on my dad's side. But there are a number of genetic conditions which have higher rates of NLD (neurofibromatosis, velocardiofacial syndrome, Williams syndrome, metachromatic leukodystrophy, etc.), probably just like autism is also associated with some genetic conditions like Fragile X and tuberous sclerosis. Also, I read a study where family members of individuals with metachromatic leukodystrophy were more likely to show an NLD pattern.
And yes, definitely NLD can be caused by brain injury (the case for the original subjects for instance). In fact, I think they used to believe it was *only* caused by brain injury (I may not be right about this however). It is also often associated with hydrocephalus, which also can cause brain injury. And of course, NLD has traits strikingly similar to Right Hemisphere Syndrome, which is caused by injury to the right hemisphere, often via a stroke (although Right Hemisphere Syndrome has some more severe symptoms as well, like neglect).
