卒中后情感障碍患者除了精神性焦虑，也会出现躯体性焦虑表现，如头晕头昏、不稳感、心悸、尿便障 碍等。作为前庭症状，患者描述的昏沉、不稳感与焦虑抑郁状态可能具有共同的神经生物学基础和信号通 路。 由于两者部分接近的临床特征和可能重叠的神经生物学基础，推测卒中后情感障碍患者可能具有持 续性姿势-知觉性头晕（PPPD）转化风险。本文对近年来卒中后情感障碍和PPPD的最新研究进行综述。

In addition to mental anxiety, patients with post-stroke affective disorder also have somatic anxiety, such as dizziness, instability, palpitations, urination and fecal disorders. As vestibular symptoms, lethargy, instability described by patients may share some common neurobiological basis and signaling pathway with anxiety and depression. Due to the similar clinical features and possible overlapping neurobiological basis of persistent postural-perceptual dizziness (PPPD), it is speculated that patients with post-stroke affective disorder may be at risk for PPPD conversion. Therefore, this article reviews the latest researches on post-stroke affective disorder and PPPD in recent years.
