Is It ADHD or Nonverbal Learning Disorder?

Parents and doctors frequently confuse ADHD and nonverbal learning disorder. Here’s a guide to figuring out if your child has NLD — and how to treat it if he does.

ADHD and NLD: Overlapping Signs

One reason doctors have trouble diagnosing NLD is because it shares similar symptoms with ADHD such as…

  • Poor social skills
  • Academic difficulties
  • Inattentivness
  • Overfocusing on certain tasks
  • Excessive talking
  • Speaking without thinking about it first

Many children with nonverbal learning disorder (NLD) were first diagnosed with attention deficit disorder. Once considered rare, NLD is thought to be as prevalent as dyslexia, affecting girls as frequently as boys.

Facts About NLD

Nonverbal learning disorder is a constellation of brain-based difficulties. Symptoms include:

  • Poor visual, spatial, and organizational skills
  • Problems with fine motor skills
  • Difficulty processing nonverbal cues—body language and facial expressions, for example
  • Precocious language acquisition and articulate speech

Young children with NLD are often good at compensating for their limitations. But once they hit puberty, children with NLD often experience severe anxiety. In adulthood, mood disorders—combined with trouble picking up social cues and setting priorities—make it hard for people with NLD to hold on to jobs and relationships.

Diagnosing NLD

The earlier the correct diagnosis is made and appropriate interventions begin, the better the outlook for a person with NLD. For diagnosis, a child usually undergoes:

  • Education and occupational therapy evaluations

Because children with NLD also have large vocabularies, outstanding memory and auditory retention, and average to superior intelligence, diagnosticians often administer the Wechsler Intelligence Scale for Children to help nail down a diagnosis. NLDers usually demonstrate a verbal IQ that’s 20 or more points higher than their performance I.Q.

Another test, the Brown ADD Scales, can help differentiate NLD from ADD.

Treating NLD

Given the complexities of NLD, children do best when they get help from a team of professionals. Unlike ADHD, nonverbal learning disorder doesn’t respond to medication. But NLD children often do well with various other kinds of intervention:

  • Social skills groups can teach kids how to

greet a friend and to greet a stranger, and to recognize and respond to teasing.

  • Occupational therapy builds a child’s tolerance for tactile experiences, improves balance, and enhances fine motor skills.

  • Typing instruction software, like

Jump Start Typing ($19.99), can help kids compensate for poor handwriting.

  • Recorded books are key for kids who learn by listening. Recording classroom lectures may also be helpful.

improve organizational skills.

    from the DSM IV
    Diagnostic Criteria For 299.80 Asperger's Disorder A. Qualitative impairment in social interaction, as manifested by at least two of the following: marked impairments in the use of multiple nonverbal behaviors such as eye-to-eye gaze, facial expression, body postures, and gestures to regulate social interaction failure to develop peer relationships appropriate to developmental level a lack of spontaneous seeking to share enjoyment, interests, or achievements with other people (e.g. by a lack of showing, bringing, or pointing out objects of interest to other people) lack of social or emotional reciprocity B. Restricted repetitive and stereotyped patterns of behavior, interests, and activities, as manifested by at least one of the following: encompassing preoccupation with one or more stereotyped and restricted patterns of interest that is abnormal either in intensity or focus apparently inflexible adherence to specific, nonfunctional routines or rituals stereotyped and repetitive motor mannerisms (e.g., hand or finger flapping or twisting, or complex whole-body movements) persistent preoccupation with parts of objects C. The disturbance causes clinically significant impairment in social, occupational, or other important areas of functioning D. There is no clinically significant general delay in language (e.g., single words used by age 2 years, communicative phrases used by age 3 years) E. There is no clinically significant delay in cognitive development or in the development of age-appropriate self-help skills, adaptive behavior (other than social interaction), and curiosity about the environment in childhood F. Criteria are not met for another specific Pervasive Developmental Disorder or Schizophrenia

    Also misdiagnosed Asperger's
    My son got his ADD non hyperactive diagnosis at age 5. Now at 11 it turns out he has Asperger's syndrome and not ADD. All you parents who are pulling out your hair thinking it just doesn't fit: look further! ADD and ADHD are commonly misdiagnosis of Asperger's, NVLD, vision problems, PDD's, etc... The list goes on. This is why so many people argue that there are too many ADD misdiagnosis, not because they are dx as ADD and are neurotypical. Oh, and Mary Warren: I agree- Most kids with NVLD have a PDD or ASD(pervasive developmental disorder or Autism Spectrum Disorder).

    NVLD
    Interesting article, but unhelpful. Seems like NVLD is a label in a vacuum.
