Study Summary

Sickle cell disease (SCD), also known as sickle cell anemia, is an inherited blood disease that can cause intense pain episodes and may lead to organ failure. Preliminary studies have shown that adults with SCD may have brain abnormalities that contribute to problems with cognitive functioning, including attention and memory difficulties. This study will use brain magnetic resonance imaging (MRI) and neuropsychological testing to examine the differences in cognitive functioning in adults with SCD and adults without SCD. 212 subjects participated in this cross-sectional study consisting of screening questionnaires, a neuropsychological testing battery, and MRI testing. Enrollment into this study ended in May 2008.

Primary Outcome

Extent of neurocognitive dysfunction in neurologically asymptomatic adult patients with sickle cell disease as measured by WAIS-III performance IQ. This quotient is based on an average of 100, with a standard deviation of 15. The Wechsler intelligence scales are not considered adequate measures of extremely high and low intelligence (IQ scores above 160 and below 40, respectively). The performance IQ is derived from scores on seven subtests: picture completion, picture arrangement, block design,
