Neurocognitive testing and functioning in adults sickle cell disease

Abstract

The impact of cerebrovascular events (CVE) on cognitive functioning in adults with sickle cell disease is not well understood. Sequelae of CVEs can adversely impact their quality of life. We reviewed neurocognitive presentation and testing in adults with sickle cell disease. We evaluated the frequency of complaints of memory disturbance using survey methodology in a sample of 109 adult patients with sickle cell disease (48 males, 61 females). A subsample of 24 patients also received a memory questionnaire where specific cognitive functions were assessed. Overall, we found that males and females did not differ in the frequency of experienced memory disturbance during painful crises. However, the frequency of men reporting that their ability to remember where they place common objects such as keys (p = 0.017) and remembering the item they intended to buy in a grocery store or pharmacy (p = 0.048) was worse now compared to when they were in high school and was greater when compared to women. The frequency of men who reported their memory was worse now than when they were in high school (p = 0.051) was also greater than in women. We concluded that memory dysfunction predicts global monthly presentation of pain. We suggest incorporating cost-effective neurocognitive screening measures as a standard of practice in sickle cell disease.
