Abstract

Objective: To investigate the assessment of cortical function changes and intrinsic circuitry in Amyotrophic Lateral Sclerosis (ALS) by transcranial magnetic stimulation (TMS). Methods: We studied 16 ALS and 11 healthy controls by single pulse TMS from abductor digiti minimi muscle (ADM). We evaluated cortical excitability parameters including, resting motor evoked potentials (MEPs) amplitude, resting MEPs threshold, central motor conduction time (CMCT), cortical silent period duration (CSPD) and cortical silent period threshold (CSPT) in ALS. Results: Resting MEPs threshold, CMCT, CSPT were increased in ALS patients compared to controls. CSPD was significantly shortened in ALS group. Conclusions: TMS findings reflect the cortical hyperexcitability in ALS.

Özet

Giriş: Bu çalışmada ALS hastalığında kortikal fonksiyon değişikliklerinin değerlendirmesi ve iç bağlantılarının değerlendirilmesi hedeflenmiştir. Yöntem: Abduktör digiti minimi kasından kayıtla tek uyarımlı TMS kullanılarak 16 ALS hastası ve 11 sağlıklı kontrol çalışıldı. İstirahat motor uyarılmış potansiyel amplitütü, istirahat motor potansiyel eşik, santral motor iletim zamanı, kortikal sessiz süre zamanı, kortikal sessiz süre eşiğinin dahil olduğu kortikal uyarılabilirlik parametrelerini değerlendirdik. Sonuçlar: İstirahat motor potansiyel eşik, santral motor iletim zamanı, kortikal sessiz süre eşiği ALS hastalarında sağlıklı kontrollere göre daha yüksek düzeyde saptandı. Kortikal sessiz süre zamanı ise ALS hastalarında istatistiksel olarak anlamlı şekilde düşük olarak saptandı. TMS bulguları ALS de kortikal artmış uyarılabilirliği yansıtabilir.
