There is often confusion between Aspergerís Syndrome (AS)and Nonverbal Learning Disabilities (NVLD). In fact, Iíve even heard these two terms used interchangably.There are though some basic differences.

NVLD is not included with Aspergerís and autism under the DSM-IVís umbrella term of Pervasive Developmental Disorders.

Both AS and NVLD children may show similar social and attentional difficulties, strong verbal skills and a confusing display of strengths and weaknesses. There are a few key items though that help in a differential diagnosis:

  • if the childís skill at deriving meaning from what she sees is a strength, then itís more likely she has Aspergerís
  • if heís helped, rather than hindered by your verbal explanations, then look to NVLD
