The goal of this study was to examine the impact of focal brain injuries on the outcomes of visual perception and visuospatial abilities in Mexican children with hemophilia who have experienced intracranial hemorrhages.
We assessed ten boys who had hemophilia with intracranial hemorrhage (HIC), six boys who had hemophilia without intracranial hemorrhage (HH), and ten boys without hemophilia (CTL). The Verbal (VIQ), Performance IQs (PIQ), and Full Scale IQs (FSIQ) from the Wechsler Intelligence Scale for Children-Mexican Revision, Visual Perception, and Visuospatial Abilities domains, which are from a neuropsychological assessment battery for Spanish-speaking children (ENI), were employed for our analysis.
The results showed that the HIC group performed in the low-average range on the PIQ and FSIQ, which was lower than the HH group. The HIC group showed low performance on visual perception tests, such as line orientation, fragmented objects, and overlapping figures, compared with their matched controls.
The results suggest that it is not the ability to recognize objects that is impaired in the HIC group, but the ability to identify objects under less favorable conditions. Our findings may have therapeutic and rehabilitative implications for the management of children with hemophilia and early focal brain lesions.
本研究旨在探讨脑局灶性损伤对伴有颅内出血的墨西哥血友病儿童视觉感知和视空间能力预后的影响。
我们评估了 10 名患有颅内出血的血友病男孩（HIC 组）、6 名患有颅内出血的血友病男孩（HH 组）和 10 名无血友病的男孩（CTL 组）。采用韦氏儿童智力量表-墨西哥修订版（Wechsler Intelligence Scale for Children-Mexican Revision）的言语智商（VIQ）、表现智商（PIQ）和全量表智商（FSIQ），以及来自西班牙语儿童神经心理评估工具包（ENI）的视觉感知和视空间能力领域进行分析。
结果显示，HIC 组在 PIQ 和 FSIQ 上的表现处于中下水平，低于 HH 组。与对照组相比，HIC 组在视觉感知测试中表现不佳，如线条定向、碎片物体和重叠图形。
研究结果表明，HIC 组受损的不是识别物体的能力，而是在不利条件下识别物体的能力。我们的发现可能对血友病和早期局灶性脑损伤儿童的管理具有治疗和康复意义。
