Research progress on the correlation between visual factors and persistent postural- perceptual dizziness symptoms / 中华神经科杂志

Persistent postural-perceptual dizziness (PPPD) is a chronic functional vestibular disease. Related studies have shown that PPPD patients often show high visual dependence in posture control or spatial orientation activities, and the symptoms are aggravated in visual motor stimulation or complex visual environment. The visual dependence of PPPD patients may be related to age factors, anxiety symptoms, visual-vestibular system interaction and neurotransmitter changes. A correct understanding of the relationship between vision and PPPD can provide more help for the clinical diagnosis and treatment of PPPD in the future. This article reviews the correlation and possible mechanism between visual factors and clinical symptoms of PPPD.
