Williams syndrome (also Williams-Beuren syndrome, sometimes called Pixieism) is a rare genetic disorder, occurring in fewer than 1 in every 20,000 live births.
Another symptom of Williams syndrome is lack of depth perception and inability to visualize how different parts assemble into larger objects (for example: assembling a jigsaw puzzle). This problem is caused by a slight defect in the brain that creates a sparsity of tissue in the visual systems of the brain. A team of researchers at the National Institute of Mental Health used functional magnetic resonance imaging (fMRI) to watch the blood flow of the brains of test subjects while they were performing two tasks involving spatial relations. Persons with Williams syndrome showed weaker activity in the section of the brain associated with spatial relations. Scans of brain anatomy of test subjects with Williams indicated a deficit of brain tissue in an area of the same section of the brain mentioned above. This deficit partially blocks transmission of visual information to the spatial relations region of the brain. In the test, all participants of the study measured in the average intelligence range to remove the possibility that the retardation aspect of Williams syndrome may have had an effect on the visual systems of the tested individuals.
