Studies suggest a large number of patients have persistent symptoms following COVID-19 infection-a condition termed "long COVID." Although children and parents often report cognitive difficulties after COVID, very few if any studies have been published including neuropsychological testing.
A retrospective chart review was completed for the first 18 patients referred for a neuropsychological evaluation from a multidisciplinary pediatric post-COVID clinic. The neuropsychological screening battery assessed verbal fluency and category switching, attention, working memory, processing speed, and verbal learning and memory. Patients' caregivers also completed standardized questionnaires regarding day-to-day mood and behavior.
At intake, the most common neurologic symptoms reported by caregivers were attention problems (83.3%), fatigue/lethargy (77.7%), sleep disturbance (77.7%), dizziness/vertigo (72.2%), and headaches (72.2%). On rating scales, most caregivers endorsed concerns for depressed mood and anxiety (14/15 and 12/15). A large proportion of patients had difficulties with attention (9/18) and depressed mood/anxiety (13/18) before COVID. On cognitive testing, the majority of the patients performed within or above broad average range (≥16th percentile) across most domains. However, a little over half of the patients performed below average on auditory attention measures.
Within our clinically referred sample, children who reported lingering cognitive symptoms after COVID-19 often had a preexisting history of attention and/or mood and anxiety concerns. Many of these patients performed below average in attention testing, but it remains to be seen whether this was due to direct effects of COVID, physical symptoms, and/or preexisting difficulties with attention or mood/anxiety.
有研究表明,大量 COVID-19 感染者在痊愈后仍存在持续性症状,这种情况被称为“长新冠”。尽管儿童及其家长常报告新冠感染后存在认知困难,但仅有极少数研究对此进行了报道,且这些研究大多未包含神经心理学测试。
对来自多学科儿科新冠后诊所的 18 名接受神经心理评估的患者的病历进行了回顾性分析。神经心理学筛查测试评估了患者的言语流畅性和类别转换、注意力、工作记忆、处理速度以及言语学习和记忆。患者的照护者还完成了关于日常情绪和行为的标准化问卷。
在入组时,照护者报告的最常见神经系统症状为注意力问题(83.3%)、疲劳/无精打采(77.7%)、睡眠障碍(77.7%)、头晕/眩晕(72.2%)和头痛(72.2%)。在评定量表上,大多数照护者对抑郁情绪和焦虑表示担忧(14/15 和 12/15)。在新冠之前,有相当大比例的患者存在注意力问题(9/18)和抑郁情绪/焦虑(13/18)。在认知测试中,大多数患者在大多数测试领域的表现均处于或高于广泛平均范围(≥第 16 百分位)。然而,超过一半的患者在听觉注意力测试中表现低于平均水平。
在我们的临床就诊样本中,报告新冠后持续存在认知症状的儿童往往存在注意力和/或情绪及焦虑问题的既往病史。这些患者中有许多人在注意力测试中表现不佳,但尚不清楚这是由于新冠的直接影响、躯体症状以及/或注意力或情绪/焦虑方面的既往困难导致的。
