What areas can NVLD effect?

NVLD can take a lot of forms, and not everyone with it will be affected in every area, and other areas are also able to be affected this is just a general list:

- exceptional skills in the areas of comprehension (understanding) and production (ability to utilize) of verbal language. Basically, we are really good at reading, writing, speech, spelling, and have large vocabularies.

- difficulties with visual spatial processing skills. Fun fact, NVLD was briefly called Visual Spatial Processing Disorder! Visual spatial processing is a term that describes the process of seeing things and then understanding how they relate to one another in space.

- difficulties with understanding non-verbal forms of communication such as tone, facial expressions, gestures, metaphors and exaggerations, and (sometimes) context.

- difficulties with math, including arithmetic, fractions, geometry, telling time, pattern recognition, and much more. This can be very similar to dyscalculia.

- difficulties socializing (often presents similar to the social difficulties faced by autistic people)

- other miscellaneous neurodivergent traits such as hyperfixations, difficulty regulating emotions, distress when faced with change, sensory overload, motor skill and coordination deficits, attention deficits, and executive dysfunction

How does that affect people with NVLD on the day to day?

Let’s use me as the example. I love to talk to people but I often run into issues because I take things very literally, struggle to read social cues, and can have trouble connecting with others. Growing up I was always in advanced English and literature classes, but was in special education for math due to my extreme difficulties with it. I have a lot of trouble dealing with last minute changes in my plans and loud noises bother me A Lot.

I struggle greatly with visual spatial processing skills, specifically for me that can manifest as not knowing where my body is in space (causing me to bump into things a lot), difficulty navigating maps, struggles with knowing left from right, a complete inability to use the knowledge of how an object looks from one angle to visualize how it would look from another angle, and many other things.

NVLD can present in a number of different ways and affect different parts of peoples lives. I have multiple neurodivergent comorbidities which can make it difficult to tease the exact symptoms apart from one another, but there are plenty of articles online where people discuss their own experiences if you look for them.

Is NVLD in the DSM/an official diagnosis?

ehhhhh it’s complicated. NVLD is not currently it’s own differentiated diagnosis within the DSM-5, however it can be diagnosed (as it is with me) under the DSM-5 as Specific Learning Disorder with Impairment in Mathematics which serves as a sort of catch all for any learning disability that affects math or areas other than reading/writing.

NVLD as its own diagnosis is a relatively new idea, as historically it’s been lumped within other diagnoses (typically autism, adhd, or specific learning disability). However over the last 15 years and especially the last 5 years, there has been a significant increase in academic literature and acknowledgement of NVLD as its own distinct diagnosis. Columbia University has been conducting research on the disorder alongside the NVLD Project, which is the only organization that exclusively does advocacy, education, and research around NVLD. These groups are doing a lot of work to attempt to get NVLD classified as its own diagnosis in future editions of the DSM.

How common is NVLD? What causes it?

NVLD is uncommonly diagnosed due to lack of official DSM recognition, misidentification as other neurodiverse conditions, and lack of awareness of NVLD from neuropsych evaluators. However one study from earlier this year estimated that between 1-8% of children have NVLD depending on what diagnostic criteria is used.

There has been some early evidence that NVLD is the result of dysfunction in the right hemisphere of the brain or more specifically the inability of the right hemisphere of the brain to effectively communicate to the left hemisphere.

Why are you telling me all of this?

The majority of people do not know that NVLD exists, and as such those of us with this condition often get left out of neurodivergent and disability communities. I would like to be included in advocacy and understood by the community since we all face very similar challenges! I really encourage y’all to learn more about Non-Verbal Learning Disability
