Abstract

Sickle cell anemia is a chronic disease that can severely affect the ability to process information quickly. The aim of this study was to evaluate the reaction time in children with sickle cell anemia using simple reaction time and choice reaction time tests. A cross-sectional study was performed at the Children's Hospital of Brasilia, with patients from the hematology outpatient clinic. The experimental group was composed of 24 sickle cell children and the control group of 22 children not affected by sickle cell anemia. The simple reaction time and choice reaction time were evaluated using equipment developed for this purpose. The results showed a significant deficit in the choice reaction time of children with sickle cell anemia (p= 0.000161). In simple reaction time, the experimental group showed less attention, committing a higher proportion of errors by omission when compared to the control group (p= 0.00678). The lower rate of success in simple reaction time and choice reaction time tests in children with sickle cell anemia may be related to the high incidence of silent cerebral infarction in this population. Another fact that may be associated with high reaction time in patients with sickle cell anemia is the lack of experience and opportunities for motor activities throughout childhood due to the pathology. KEYWORDS: chronic disease; hemoglobin, sickle; child development; psychomotor performance; brain injuries.
镰状细胞性贫血患儿反应时间的评估
镰状细胞贫血是一种严重影响快速处理信息能力的慢性疾病。本研究的目的是通过简单反应时间和选择反应时间测试来评估镰状细胞性贫血儿童的反应时间。在巴西利亚儿童医院对血液科门诊的患者进行了横断面研究。实验组由24名镰状细胞性贫血儿童组成,对照组由22名未受镰状细胞贫血影响的儿童组成。使用为此目的开发的设备评估简单反应时间和选择反应时间。结果显示,镰状细胞性贫血患儿的选择反应时间明显不足(p=0.0000161),与对照组相比,由于遗漏而犯错误的比例更高(p=0.00678)。镰状细胞性贫血儿童的简单反应时间和选择反应时间测试的成功率较低,可能与该人群中无症状性脑梗死的高发病率有关。镰状细胞性贫血患者的另一个可能与高反应时间有关的事实是,由于病理学的原因,整个儿童期缺乏运动活动的经验和机会。关键词:慢性病;血红蛋白、镰刀;儿童发展;心理运动表现;脑损伤。
