Aim: Non-motor symptoms (NMS) significantly impact Parkinson's disease (PD) patients, yet their relationship with disease progression and quality of life requires further investigation. To evaluate the associations between NMS burden, motor symptoms, disease duration, and quality of life in PD patients.
Methods: This cross-sectional study included 141 PD patients. NMS were assessed using the NMS Scale. Motor symptoms were evaluated using Unified Parkinson's Disease Rating Scale Part III (UPDRS-III) and Hoehn-Yahr (H&Y) staging. Quality of life was measured using Parkinson's Disease Questionnaire-39 (PDQ-39). Disease duration was categorized into three groups: <4 years, 5-8 years, and >9 years. Statistical analyses included correlation coefficients, multivariate logistic regression, and linear regression models.
Results: NMS burden strongly correlated with quality of life (r=0.507, p<0.001) and motor symptoms (r=0.504, p<0.001). Age (p<0.001), disease duration 5-8 years (p<0.001) or 9< years (p<0.001), UPDRS-III (p<0.001), LEDD (p<0.001) and H&Y >3 (p<0.001) were significant in the univariate analysis. In the multivariate stage, age (p<0.001), disease duration 9< years (p=0.015) and UPDRS-III (p=0.004) remained statistically significant. Each one-unit increase in UPDRS-III increased PDQ-39 by 1.91 points and each one-point increase in NMS total score increased PDQ-39 by 3.35 points (p<0.001 for each).
Conclusion: NMS significantly impact quality of life in PD patients, with burden increasing alongside disease duration. Motor symptom severity and NMS represent independent determinants of disease progression and quality of life.

Parkinson Hastalarında Motor Dışı Semptomların ve Yaşam Kalitesinin Klinik İlişkileri: Motor ve Non-Motor Özelliklerin Analizi

Öz

Amaç: Non-motor semptomlar (NMS) Parkinson hastalığı (PH) hastalarını önemli ölçüde etkiler, ancak hastalığın ilerlemesi ve yaşam kalitesi ile ilişkilerinin daha fazla araştırılması gerekir. PH hastalarında NMS yükü, motor semptomlar, hastalık süresi ve yaşam kalitesi arasındaki ilişkileri değerlendirmek.
Yöntemler: Bu kesitsel çalışmaya 141 PH hastası dahil edilmiştir. NMS, NMS Ölçeği kullanılarak değerlendirilmiştir. Motor semptomlar Unified Parkinson's Disease Rating Scale Part III (UPDRS-III) ve Hoehn-Yahr (H&Y) evrelemesi kullanılarak değerlendirildi. Yaşam kalitesi Parkinson Hastalığı Anketi-39 (PDQ-39) kullanılarak ölçülmüştür. Hastalık süresi üç gruba ayrılmıştır: <4 yıl, 5-8 yıl ve >9 yıl. İstatistiksel analizler korelasyon katsayılarını, çok değişkenli lojistik regresyonu ve doğrusal regresyon modellerini içermektedir.
Bulgular: NMS yükü yaşam kalitesi (r=0.507, p<0.001) ve motor semptomlar (r=0.504, p<0.001) ile güçlü korelasyon gösterdi. Tek değişkenli analizde yaş (p<0.001), hastalık süresi 5-8 yıl (p<0.001) veya 9< yıl (p<0.001), UPDRS-III (p<0.001), LEDD (p<0.001) ve H&Y >3 (p<0.001) anlamlı bulunmuştur. Çok değişkenli aşamada, yaş (p<0.001), hastalık süresi 9< yıl (p=0.015) ve UPDRS-III (p=0.004) istatistiksel olarak anlamlı kalmıştır. UPDRS-III'teki her bir birimlik artış PDQ-39'u 1,91 puan ve NMS toplam skorundaki her bir puanlık artış PDQ-39'u 3,35 puan artırmıştır (her biri için p<0,001).
Sonuç NMS, PH hastalarında yaşam kalitesini önemli ölçüde etkiler ve hastalık süresi ile birlikte yükü artar. Motor semptom şiddeti ve NMS, hastalığın ilerlemesi ve yaşam kalitesinin bağımsız belirleyicileridir.
