As in line bisection, in time bisection, neglect patients fail to process the first/left part of time representation (Mental-Time-Line-MTL) resulting in a rightward shift of the interval midpoint. A leftward shift of spatial attention after one session of prismatic-adaptation (PA) reduces this deficit. The impact on daily life of time deficit is little investigated in neglect. Here we study the time deficit and its ecological impact in an outpatient with neglect (LL) and the effects of a PA-treatment (ten sessions) on the deficit and its impact.

Before and after PA-treatment, LL completed a: time-bisection-task assessing the MTL in the milliseconds-seconds range; lifespan-task assessing the MTL in the lifespan range; qualitative interview assessing the impact on daily routines. Patient’s performance on the tasks was compared with the performance of non-neurological controls.

Before PA-treatment, LL showed a rightward shift in the time-bisection-task and a compression of life events distribution in the lifespan-task. The feeling “to be forward in time” emerged in the interview. The PA-treatment reduced the deficits in the tasks and the feeling “to be forward in time” in the interview. PA-treatment is suggested as a powerful instrument for the reduction of time deficit and its ecological impact in neglect patients.

与线平分一样，在时间平分中，疏忽的患者无法处理时间表示的第一部分/左部分（Mental-Time-Line-MTL），从而导致间隔中点向右移动。在进行一次棱柱适应（PA）会话后，空间注意力向左移动可减少此缺陷。很少有人忽视时间不足对日常生活的影响。在这里，我们研究了门诊疏忽患者（LL）的时间亏缺及其对生态的影响，以及PA疗法（十次疗程）对时间亏缺及其影响的影响。

在进行PA处理之前和之后，LL完成了：时分任务，以毫秒为单位评估MTL。寿命任务，评估寿命范围内的MTL；定性访谈，评估对日常工作的影响。将患者在任务上的表现与非神经控制的表现进行了比较。

在进行PA治疗之前，LL在时间平分任务中显示了向右移动，并且在寿命任务中显示了生活事件分布的压缩。采访中出现了“要及时前进”的感觉。PA的治疗减少了任务中的缺陷，并减少了面试中“要及时前进”的感觉。建议将PA治疗作为减少时间不足及其对忽视患者的生态影响的有力手段。
