The cause of NVLD isn’t fully understood. It seems to be related to problems in the right side of the brain, which processes sensory input like sight, hearing, and touch. This side of the brain helps you adapt to new and novel situations.

Some scientists also think NVLD is related to problems in the frontal lobe. This part of the brain is responsible for things like planning, organizing, and impulse control (i.e., executive functions).

Is NVLD hereditary?

Yes, NVLD appears to run in families. Several studies support this. However, more research needs to be done to fully understand the genetic origins of NVLD.

Medical causes of NVLD

Outside of genetics, some other causes may increase a child’s risk of NVLD. According to the Tufts Medical Center, these include: 

  • A mother who smoked, drank alcohol, or was ill while pregnant
  • Very long labor at birth
  • Having the umbilical cord wrapped around the neck
  • Serious infections as a young infant

There is also the possibility that head injuries as a young child could cause NVLD, though this would be rare. 

Ongoing research

Scientists are researching the causes of NVLD using fMRI scans and other technology. While the research is still in early stages, they have discovered the people with NVLD do have brains that function differently from people with Autism Spectrum Disorder (ASD). This is helping researchers to better understand what causes NVLD and how it is different from other disorders like autism and ADHD.
