Psychosis is characterized by overt disruptions in thought, perceptions, and behavior. Complex syndromes presenting with psychosis, including schizophrenia spectrum disorders, mood disorders, and medical illnesses, are differentiated by characteristic patterns of symptom presentation and course of illness. Accurate diagnosis is important to guide treatment and to avoid inaccurate labeling, because most youth reporting psychotic-like experiences do not have a true psychotic disorder.

儿童和青少年的精神病

精神病的特征是思想，观念和行为的明显破坏。表现为精神病的复杂综合症，包括精神分裂症谱系障碍，情绪障碍和内科疾病，通过症状表现和病程的特征性模式来区分。准确的诊断对于指导治疗和避免贴错标签非常重要，因为大多数报告有类似精神病经历的年轻人并没有真正的精神病。
