Abstract

Objective The pulvinar thalami is one of the important thalamic nuclei associated with visual processing and multisensory integration. Alterations in thalamo-visual connections related to photophobia and sensory hypersensitivity have been reported in patients with migraine. In this study, it was aimed to compare the right and left pulvinar thalami volumes and the asymmetry between these structures in female patients diagnosed with migraine and healthy individuals. Materials and Methods The study included 40 female migraine patients aged 20–49 years and 30 healthy female individuals aged 22–47 years who underwent cranial magnetic resonance imaging at Balıkesir University Training and Research Hospital between 2023 and 2024. Cranial MR images were transferred to the VolBrain software, and the total, right, and left volumes of the pulvinar thalami as well as asymmetry values were morphometrically evaluated. Statistical analyses were performed using SPSS 25 software. Independent Samples T-Test was used for intergroup comparisons, while Pearson correlation analysis was used to evaluate the relationships with age. Results No significant difference was found between patients diagnosed with migraine and healthy individuals in terms of total, right, and left pulvinar thalami volumes (p>0.05). However, a significant negative correlation was found between the asymmetry of the right and left pulvinar thalami and age in the migraine group (r=-0.333; p=0.036). No significant correlation was detected in the control group. Conclusion Although no significant morphometric alterations were detected in pulvinar thalami volumes in migraine patients, an increase in pulvinar asymmetry was observed with aging. Considering the central role of the pulvinar thalami within the thalamo-visual system, it is thought that functional connectivity alterations rather than structural changes may play a more prominent role in migraine pathogenesis.

Özet

Amaç: Pulvinar thalami, talamusun görsel işlemleme ve multisensoriyel entegrasyon ile ilişkili önemli çekirdeklerinden biridir. Migren hastalarında özellikle fotofobi ve duyusal hassasiyet ile ilişkili talamo-vizüel bağlantılarda değişiklikler olduğu bildirilmektedir. Bu çalışmada migren tanısı almış olan kadın hastalarda sağ ve sol pulvinar thalami hacimleri ile bu yapılar arasındaki asimetrinin sağlıklı bireylerle karşılaştırılması amaçlandı. Gereç ve Yöntem: Çalışmaya Balıkesir Üniversitesi Eğitim ve Araştırma Hastanesi’nde 2023-2024 yılları arasında kranial manyetik rezonans görüntülemesi bulunan 20-49 yaş aralığında 40 kadın migren hastası ile 22-47 yaş aralığında 30 sağlıklı kadın birey dahil edildi. Kranial MR görüntüleri VolBrain yazılımına aktarılarak pulvinar thalami’nin total hacmi, sağ ve sol hacimleri ile asimetri değerleri morfometrik olarak değerlendirildi. İstatistiksel analizler SPSS 25 programı kullanılarak gerçekleştirildi. Gruplar arası karşılaştırmalarda Bağımsız Grup T-Testi, yaş ile ilişkilerin değerlendirilmesinde Pearson korelasyon analizi kullanıldı. Bulgular: Migren tanısı almış olan hastalar ile sağlıklı bireyler arasında total, sağ ve sol pulvinar thalami hacimleri açısından anlamlı farklılık saptanmadı (p>0,05). Bununla birlikte migren grubunda sağ ve sol pulvinar thalami arasındaki asimetri ile yaş arasında negatif yönde anlamlı korelasyon bulundu (r=-0,333; p=0,036). Kontrol grubunda ise anlamlı korelasyon saptanmadı. Sonuç: Migren hastalarında pulvinar thalami hacimlerinde belirgin morfometrik değişiklik saptanmamış olsa da yaşla birlikte pulvinar asimetrisinde artış olduğu görülmektedir. Pulvinar thalami’nin talamo-vizüel sistem içerisindeki merkezi rolü göz önünde bulundurulduğunda, migren patogenezinde yapısal değişikliklerden çok fonksiyonel bağlantı değişikliklerinin ön planda olabileceği düşünülmektedir.
