Arthur T Knackerbracket has found the following story:

Nonverbal learning disability (NVLD), a poorly understood and often-overlooked disorder that causes problems with visual-spatial processing, may affect nearly 3 million children in the United States, making it one of the most common learning disorders, according to a new study by led by Columbia University Irving Medical Center.

The study, the first to estimate the prevalence of NVLD in the general population, was published online today in JAMA Network Open.

"NVLD is a huge and hidden public health burden," said Jeffrey Lieberman, Chair of Psychiatry at the Columbia University Vagelos College of Physicians and Surgeons and Director of the New York State Psychiatric Institute. "This important work might never have come to light if not for the support of dedicated advocate and their philanthropic support. We hope that these findings raise awareness of the disorder and lead to an understanding of its neurobiology and better treatments."

The name of this neurodevelopmental disorder may be part of the problem: children with NVLD are not nonverbal, as the name suggests, and have no difficulty reading. Instead, children with NVLD have difficulty processing visual-spatial sensory information, which can cause problems with math, executive function, and fine motor and social skills. "Children with this disorder might shy away from doing jigsaw puzzles or playing with Legos," says lead author Amy E. Margolis, PhD, assistant professor of medical psychology at Columbia University Vagelos College of Physicians and Surgeons. "They may have trouble tying their shoes, using scissors, or learning routes or schedules."

NVLD was first described in 1967, but compared with other learning disorders it has received little attention. There's little consensus among physicians on how to diagnose the disorder, and it is not included in the current edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM). The cause of NVLD is not known and there are no treatments.

Few parents have heard of NVLD. "Most parents recognize that a child who isn't talking by age two should be evaluated for a learning disorder. But no one thinks twice about kids who have problems with visual-spatial tasks," says Margolis.

[...] Margolis advises parents to seek evaluation for children with symptoms of NVLD. "Diagnosis can be accomplished using basic assessment tools," says Margolis. "It doesn't have to involve complex and costly neuropsychological testing. We envision that all clinicians who use DSM5 will be able to use our new criteria to determine who may meet criteria. They can then send patients for basic psychological testing that is always available through schools to identify/quantify a problem with visual-spatial processing."

    They all start with just a gradient from one point to everywhere else (little Xs with the brush), and it looks like nothing...

    I found it funny my sister-in-law who does graphic design for a living hadn't ever seen him before. About 20 minutes in, she exclaimed, "He's STILL using a 2 inch brush?!?! HOW!?!?!"
