Abnormal body balance and cognitive dysfunction may develop in elderly patients with chronic vestibular dysfunction.
To evaluate the relationship between cognitive processing and body balance in elderly patients with chronic peripheral vestibular disease.
Cross-sectional.
Seventy-six patients (> 60 years) with chronic peripheral vestibular dysfunction and dizziness for more than three months were enrolled. The tests for investigating body balance were: the Berg Balance Scale (BBS), Dynamic Gait Index (DGI), Timed Up and Go Test (TUGT) Timed Up and Go Test modified (TUGTm); the Mini Mental State Examination (MMSE), Test Clock (RT,) and Verbal Fluency Test (VF) were applied for assessing cognition.
The mean age was 69.03 years (SD=6.21 years); most were female (82.9%). There was a significant negative correlation between the MMSE and the TUGT (ρ=-0.312; p=0.01), MMSE and TUGTm (ρ=-0.306; p=0.01), FV and TUGT (ρ=-0.346; p=0.01), and FV and TUGTm (ρ=-0.536; p=0.01); there was a significant positive correlation between the TR and BBS (ρ=0.343; p=0.01), TR and DGI (ρ=0.298; p=0.01), FV and BBS (ρ=0.299; p=0.01), and FV and DGI (ρ=0.306; p=0.01).
Elderly patients with chronic peripheral vestibular disease and worse performance in body balance tests have functional impairment in cognitive skills.
评估慢性周围性前庭疾病老年患者认知加工与身体平衡之间的关系。
纳入 76 例（>60 岁）慢性周围性前庭功能障碍伴头晕超过 3 个月的患者。评估身体平衡的测试包括：伯格平衡量表（BBS）、动态步态指数（DGI）、计时起立行走测试（TUGT）、改良计时起立行走测试（TUGTm）；简易精神状态检查（MMSE）、测试时钟（RT）和词语流畅性测试（VF）用于评估认知。
平均年龄为 69.03 岁（SD=6.21 岁）；大多数为女性（82.9%）。MMSE 与 TUGT（ρ=-0.312；p=0.01）、MMSE 与 TUGTm（ρ=-0.306；p=0.01）、FV 与 TUGT（ρ=-0.346；p=0.01）、FV 与 TUGTm（ρ=-0.536；p=0.01）呈显著负相关；TR 与 BBS（ρ=0.343；p=0.01）、TR 与 DGI（ρ=0.298；p=0.01）、FV 与 BBS（ρ=0.299；p=0.01）、FV 与 DGI（ρ=0.306；p=0.01）呈显著正相关。
慢性周围性前庭疾病老年患者，身体平衡测试表现越差，认知功能障碍越严重。
