Estrogen Effects on Cognition in Girls With Turner Syndrome

In Brief

A Phase 2 clinical trial evaluating cognitive tests and scales for Gonadal Dysgenesis and Turner's Syndrome. Completed, across 1 site.

Detailed Summary

The development of the brain in females is a result of a combination of factors. During puberty estrogen plays a role in influencing brain development. Cultural and environmental factors also play a role in the development of the brain. Female patients with Turner syndrome lack the ability to produce estrogen due to undeveloped ovaries. Therefore, Turner syndrome is the perfect condition to study how estrogen (or the lack of estrogen) influences a person's behavior and thinking. This study will compare cognitive differences (visual motor skills, visual-spatial, psychosocial behavior, and visual memory) of patients with Turner syndrome to normal patient controls. Researchers will use the Weschler Intelligence Scale for Children-Revised (WISC-R) along with other tests and scales to measure different aspects of the patient's cognitive ability. In addition the study will review patients with Turner syndrome who previously received estrogen replacement as infants and children in a related research study. Researchers hope to demonstrate that estrogen replacement will improve cognition and behavior in girls with Turner syndrome.
