What is it about?
This study is about cognitive assessment of persons with Rett syndrome and may have implications for intervention. Girls and women with Rett syndrome were assessed using Teller Acuity Cards and the Fagan Test of Preferential Looking. Their parents were interviewed about the participants' communication skills.

Why is it important?
The study is important in showing that cognitive functioning may be measured in persons with Rett syndrome. The visual functioning of the participants showed arrested development, scoring significantly lower on the Fagan test than a normal comparison group. Their visual processing and memory declined with age, while the comparison group showed slight improvement.
Perspectives
It's noteworthy that age at onset of Rett syndrome symptoms and speech measures were inversely correlated with visual processing and memory. It should also be noted that patterns of persistent looking were linked to low cognitive function. This knowledge may be useful for directing differential intervention approaches for differential subgroups of Rett syndrome.
