Attention impairments are frequent in stroke patients with important consequences on the rehabilitation outcomes and quality of life. The aim of the study was to perform a comprehensive assessment of selective and intensive attention processes in a large population of brain-damaged patients, evaluating the influence of the side and site of the brain lesion, the time from stroke, and the concomitant presence of aphasia or neglect. We assessed 204 patients with a first unilateral brain lesion and 42 healthy individuals with three subtests of the Test of Attentional Performance (TAP): Alertness, Go-No Go, and Divided Attention. 44.4% of patients had an impairment in both intensive and selective aspects of attention, 5.6% had deficits only in the intensive component, and 31.8% had deficits only in selective tasks. More than 80% of the patients fell below the cut-off point on at least one task. Patients with a right hemispheric lesion (RHL) were more impaired than patients with a left hemispheric lesion (LHL) especially in tonic and phasic alertness. Patients with total anterior infarcts (TACI) presented the worst profile compared to other stroke subtypes, with a difference between total and lacunar subtypes in the Alertness test, independent of the presence of warning. Patients in the chronic phase had shorter RTs than acute patients only in the Alertness test. In patients with LHL, the presence of aphasia was associated with a greater deficit in selective attention. In patients with RHL, the presence of unilateral neglect was associated with impaired alertness and selective attention. Attention deficits are common after a unilateral first stroke. In keeping with the hierarchical organization of attention functions, results confirm the important role of the right hemisphere for the intensive components of attention, also highlighting the involvement of left hemisphere functioning for the selective aspects, possibly indicating a role of its linguistic functions.

中风患者的注意缺陷：病变特征，中风时间和伴随的神经心理缺陷的作用。

中风患者的注意力障碍经常发生，对康复结果和生活质量产生重要影响。这项研究的目的是对大量脑损伤患者进行选择性和密集注意过程的综合评估，评估大脑病变的一侧和部位的影响，中风后的时间以及是否同时出现脑损伤。失语或忽视。我们通过注意力表现测验（TAP）的三个子测验评估了204例患有单方面首发脑病变的患者和42名健康个体：警觉性，通过/不通过和分散注意力。44.4％的患者在注意力的集中和选择性方面均受损，5.6％的患者仅在强化成分方面存在缺陷，31.8％的患者仅在选择性任务方面存在缺陷。至少一项任务中，超过80％的患者跌至临界点以下。右半球病变（RHL）的患者比左半球病变（LHL）的患者更容易受损，尤其是在进补和阶段性警觉方面。与其他中风亚型相比，具有全前梗塞（TACI）的患者表现最差，在Alertness测试中，总的和腔隙性亚型之间存在差异，与是否存在警告无关。仅在机敏测试中，慢性期患者的RTs比急性患者短。在LHL患者中，失语症与选择性注意的更大缺陷相关。在RHL患者中，单方面忽视的存在与机敏性和选择性注意受损有关。单侧第一次中风后注意力不足是常见的。
