Abstract

ABSTRACTAcquired Brain Injury (ABI), an important cause of long-term disability, is associated with increased rates of depression in addition to common cognitive and physical consequences. Past research has linked post-ABI depression to injury severity (e.g., extent of physical or cognitive impairment) and premorbid mood problems. In the general (non-ABI) population, depression is associated with cognitive vulnerabilities that have informed the development of psychological interventions. In this observational study in a heterogeneous sample of individuals with chronic stage ABI, we examine two cognitive vulnerabilities - dysfunctional attitudes (DAs) and autobiographical memory specificity - and explore whether these are linked to depression symptoms and ongoing cognitive difficulties as in the general population. Compared to control participants, individuals with an ABI demonstrated increased endorsement of DAs and reduced specificity of autobiographical memory recall. Within the ABI group, cognitive vulnerability-depression symptom correlations were detected for an explicit measure of DAs, but not for a more implicit DA measure or for autobiographical memory specificity. While individual differences in injury severity and other factors likely obscured subtle relationships between mood and cognitive vulnerabilities, evidence of these vulnerabilities may be relevant to changes in identity and psychological interventions that target low mood in ABI.
后天性脑损伤的认知脆弱性和抑郁情绪。
摘要获得性脑损伤(ABI)是导致长期残疾的一个重要原因,除了常见的认知和身体后果外,还与抑郁症发病率的增加有关。过去的研究表明,脑损伤后抑郁与损伤严重程度(如身体或认知障碍程度)和病前情绪问题有关。在普通(非脑损伤)人群中,抑郁与认知方面的脆弱性有关,这为心理干预措施的开发提供了依据。在这项针对慢性期ABI患者的异质性样本的观察性研究中,我们检查了两种认知脆弱性--功能障碍态度(DAs)和自传体记忆特异性--并探讨了它们是否与普通人群中的抑郁症状和持续的认知困难有关。与对照组受试者相比,有 ABI 的受试者对 DAs 的认可度增加,而对自传体记忆回忆的特异性降低。在缺血性心肌梗死组中,认知脆弱性与抑郁症状之间的相关性在一项明确的认知障碍测量中被检测到,但在一项更隐性的认知障碍测量或自传体记忆特异性测量中却没有被检测到。虽然受伤严重程度的个体差异和其他因素可能掩盖了情绪和认知脆弱性之间的微妙关系,但这些脆弱性的证据可能与针对 ABI 情绪低落的身份变化和心理干预有关。

期刊介绍: Neuropsychological Rehabilitation publishes human experimental and clinical research related to rehabilitation, recovery of function, and brain plasticity. The journal is aimed at clinicians who wish to inform their practice in the light of the latest scientific research; at researchers in neurorehabilitation; and finally at researchers in cognitive neuroscience and related fields interested in the mechanisms of recovery and rehabilitation. Papers on neuropsychological assessment will be considered, and special topic reviews (2500-5000 words) addressing specific key questions in rehabilitation, recovery and brain plasticity will also be welcomed. The latter will enter a fast-track refereeing process.
