Visual hallucinations can be elementary or complex and appear in a wide variety of neurological disorders. Hallucinations associated with seizures can either be ictal or part of a post-ictal cortical release phenomenon, and their features may help distinguish their etiology. We describe two patients with suspected ictal occipital lobe lesions with elementary hallucinations that were followed by post-ictal complex hallucinations.The pathophysiologies of elementary and complex hallucinations are reviewed. The sequential occurrence of these two distinct types of hallucinations in these patients emphasizes the observation that hallucinations associated with seizures can result from both irritative and cortical release mechanisms.
视幻觉可以是简单的或复杂的，并且出现在多种神经系统疾病中。与癫痫发作相关的幻觉既可以是发作期的，也可以是发作后皮质释放现象的一部分，其特征可能有助于区分其病因。我们描述了两名疑似发作期枕叶病变且伴有简单幻觉，随后出现发作后复杂幻觉的患者。本文对简单和复杂幻觉的病理生理学进行了综述。这两名患者中这两种不同类型幻觉的相继出现，强调了与癫痫发作相关的幻觉可由刺激性和皮质释放机制共同导致这一观察结果。
