Early researchers in the syndrome of NVLD Johnson and Myklebust characterize how the children appear in a classroom: "An example is the child who fails to learn the meaning of the actions of others....We categorize this child as having a deficiency in social perception, meaning that he has an inability which precludes acquiring the significance of basic nonverbal aspects of daily living, though his verbal level of intelligence falls within or above the average. "In the adolescent years, when schoolwork becomes more abstract and the executive demands for time management, organization, and social interactions increase, students with NVLD begin to struggle. They focus on separate details and struggle to summarize information or to integrate ideas into a coherent whole, and they struggle to apply knowledge to other situations, to infer implicit information, to make predictions, and to organize information logically.As adults, tasks such as driving a car or navigating to an unfamiliar location may be difficult. Difficulty with keeping track of responsibilities or managing social interactions may affect job performance.People with NVLD may also fit the diagnostic criteria of dyscalculia, dysgraphia, or dyspraxia. Cause
Research suggests that there is an association with an imbalance of neural activity in the right hemisphere of the brain connected to the white matter. Diagnosis
Nonverbal learning disability (NVLD) is characterized by core deficits in visualspatial processing in the presence of intact verbal ability. Additional diagnostic criteria include Average to Superior verbal intelligence and deficits in visuoconstruction abilities, fine-motor coordination, mathematical reasoning, visuospatial memory and social skills.
Acrocraniofacial dysostosis, also known as Kaplan Plauchu Fitch syndrome is a very rare hereditary disorder which is characterized by cranio-facial dysmorphisms, hearing loss, digital clubbing, and osseous anomalies. Only 2 cases have been described in medical literature. Description
The following is a list of the symptoms of the disorder:

Cranio-facial
Acrocephaly
Hypertelorism
Ptosis
Proptosis
Down-slanting parpebral fissures
High nasal bridge
Nostril anteversion
Short philtrum
Cleft palate
Micrognathia
Ear abnormalities
Preauricular sinus or cyst

Auditory
Hearing loss

Osseous
Metatarsus adductus
First brachymetacarpia
First brachymetatarsia
Proximally placed first toes
Craniosynostosis
Pectus excavatum
Partial duplication of the thumbs distal phalanx
Malleus and incus dysplasia
Tall lumbar vertebrae associated with increased interpedicular distance

Discovery
This disorder was first discovered in 1988 by Kaplan et al. when they described two sisters born to consanguineous parents with all the symptoms mentioned above. They suggested this disorder to be inherited in an autosomal recessive fashion. == References ==
