持续性姿势-知觉性头晕的中医病机及证治探讨OACSTPCD

Persistent postural-perceptual dizziness (PPPD) is a prevalent chronic functional dizziness observed in clinical practice. It is primarily characterized by persistent dizziness,instability,or non-rotational vertigo,which exacerbates with upright posture,and during active or passive visual motion stimuli. PPPD's core symptoms incorporate key aspects of chronic subjective dizziness and related conditions,often leading to frequent misdiagnosis or underdiagnosis by clinicians. In Traditional Chinese Medicine (TCM),PPPD is categorized under dizziness/vertigo. Drawing on the etiology,pathogenesis,TCM syndromes,and treatment strategies for dizziness/vertigo documented in ancient Chinese medical texts,PPPD's clinical symptoms can be classified into three primary syndrome types. Over time,TCM practitioners have distilled PPPD treatment into five aspects and seven therapeutic principles,emphasizing a multifaceted and multi-level approach to managing the condition. Additionally,TCM doctors have recommended various herbal prescriptions tailored to different pathophysiological mechanisms of dizziness/vertigo,such as Sini Powder (Frigid Extremities Powder),Qiqi Decoction (Seven Qi Decoction),and Suanzaoren Decoction (Sour Jujube Decoction). These formulations offer valuable references for clinicians employing TCM in the treatment of PPPD.
