Drug discovery based on classic models for cognitive impairment and negative symptoms of schizophrenia have met with only modest success. Because cognitive impairment and negative symptoms may result from disruptions in neurodevelopment, more complex developmental models that integrate environmental and genetic risk factors are needed. In addition, it has become clear that biochemical pathways involved in schizophrenia form complex, interconnected networks. Points at which risk factors converge, such as brain-derived neurotrophic factor (BDNF) and protein kinase B (AKT), and from which processes involved in neuroplasticity diverge, are of particular interest for pharmacologic interventions. This paper reviews elements of neurodevelopmental models for cognitive deficits and negative symptoms of schizophrenia with the aim of identifying potential targets for interventions.
基于经典模型的认知障碍和精神分裂症阴性症状的药物发现仅取得了适度的成功。由于认知障碍和阴性症状可能是由于神经发育紊乱引起的,因此需要更复杂的整合环境和遗传风险因素的发育模型。此外,已经清楚的是,涉及精神分裂症的生化途径形成复杂的、相互关联的网络。风险因素汇聚的点,如脑源性神经营养因子 (BDNF) 和蛋白激酶 B (AKT),以及涉及神经可塑性的过程分歧的点,对于药物干预特别有意义。本文综述了精神分裂症认知缺陷和阴性症状的神经发育模型的要素,旨在确定干预的潜在靶点。
