Patients with schizophrenia are often plagued by sleep disturbances that can exacerbate the illness, including potentiating psychosis and cognitive impairments. Cognitive dysfunction is a core feature of schizophrenia with learning and memory being particularly impaired. Sleep disruptions often accompanying the illness and may be key mechanism that contribute to these core dysfunctions. In this special translational neuroscience feature, we highlight the role of sleep in mediating cognitive function, with a special focus on learning and memory. By defining dysfunctional sleep architecture and rhythms in schizophrenia, we focus on the disarray of mechanisms critical to learning and memory and postulate an association between sleep disturbances and cognitive impairments in the disorder. Lastly, we review preclinical models of schizophrenia and highlight exciting translational research that may lead to new therapeutic approaches to alleviating sleep disturbances and effectively improving cognitive function in schizophrenia.
精神分裂症患者常受到睡眠障碍的困扰,这可能会使病情恶化,包括加重精神病和认知障碍。认知功能障碍是精神分裂症的核心特征,其中学习和记忆尤为受损。睡眠紊乱常伴随疾病发生,可能是导致这些核心功能障碍的关键机制。在这个特别的转化神经科学专题中,我们强调了睡眠在介导认知功能中的作用,特别关注学习和记忆。通过定义精神分裂症中功能失调的睡眠结构和节律,我们关注到对学习和记忆至关重要的机制的混乱,并假设睡眠障碍与该疾病中的认知障碍之间存在关联。最后,我们回顾了精神分裂症的临床前模型,并强调了令人兴奋的转化研究,这些研究可能为缓解睡眠障碍和有效改善精神分裂症的认知功能提供新的治疗方法。
