ABSTRACT

Background: The pattern of post-stroke aphasia in Spanish speakers has not previously been reported. Furthermore, the association between aphasia type and demographic variables is not clearly understood.

Aims: To investigate the incidence and type of aphasia in first-ever acute stroke during the early chronic and later chronic periods in native Spanish speakers and the effect of demographic variables.

Methods & Procedures: Spanish versions of Western Aphasia Battery and Boston Diagnostic Aphasia Examination were used for language assessment. Lesion localization was done by using computerized axial tomography and magnetic resonance imaging. Final simple included 243 (97.98%) right-handed, and five (2.02%) left-handed participants; 143 men and 105 women with a mean age of 58.68 years.

Outcomes & Results: The types of aphasia included – 14.1% Broca’s, 15.3% Wernicke’s, 10.1% Conduction, 9.3% Transcortical Sensory, 1.6% Transcortical Motor, 28.2% Anomic, 4.8% Global, and 16.5% Mixed non-fluent. Wernicke’s aphasia, along with Transcortical Sensory aphasia was more frequently observed in older people. Broca’s aphasia was more prevalent but less severe in women than in men. Auditory Comprehension and Naming negatively correlated with age, while schooling positively correlated with Auditory Comprehension. Time since onset did not significantly affect the type of aphasia. Schooling correlated with the severity of Anomic aphasia.

Conclusions: The most common type of aphasia in our sample was Anomic aphasia. Older people had an increased probability to present a fluent type of aphasia. Broca’s aphasia was more frequent but less severe in women.

摘要

背景：以前没有报道过西班牙语使用者中风后失语症的模式。此外，还不清楚失语症类型和人口统计学变量之间的关联。

目的: 调查母语为西班牙语的早期慢性和晚期慢性期首次急性中风失语症的发病率和类型，以及人口统计学变量的影响。

方法和程序：使用西语失语症电池和波士顿诊断性失语症考试的西班牙语版本进行语言评估。病变定位是通过使用计算机轴向断层扫描和磁共振成像完成的。最后的简单包括 243 (97.98%) 名右手参与者和 5 名 (2.02%) 左手参与者；143 名男性和 105 名女性，平均年龄为 58.68 岁。

结果和结果：失语症的类型包括 – 14.1% Broca 型、15.3% Wernicke 型、10.1% 传导型、9.3% 经皮层感觉型、1.6% 经皮层运动型、28.2% 失语症、4.8% 全球型和 16.5% 混合型非流利型。Wernicke 失语症和经皮层感觉失语症在老年人中更常见。与男性相比，布洛卡失语症在女性中更为普遍，但严重程度较低。听觉理解和命名与年龄呈负相关，而学校教育与听觉理解呈正相关。自发病以来的时间对失语症的类型没有显着影响。学校教育与失语症的严重程度相关。

结论：我们样本中最常见的失语症类型是失语症。老年人出现流利型失语症的可能性增加。Broca 失语症在女性中更常见，但不那么严重。
