Transkraniyal Doğru Akım Uyarımı: Bir Gözden Geçirme
GH Sayar, E Özten, N Tarhan
Nöropsikiyatri İstanbul Hastanesi, İstanbul
Transkraniyal doğru akım uyarımı (TDAU) kortikal işlev modülasyonu için kullanılan noninvazif bir tekniktir. TDAU, kafa derisi üzerine yerleştirilmiş elektrotlar kullanılarak serebral korteksten zayıf bir doğrudan elektrik akım geçişini kullanır. Katodal TDAU ile kortikal uyarılabilirlik azalır ve anodal TDAU ile uyarılabilirlik artar. Psikiyatrik bozuklukların tedavisinde TDAU kullanımı üzerine birkaç araştırma vardır. Ancak farklı hasta gruplarında farklı parametreler ile uyarım yapılabilmesi için ek çalışmalara ihtiyaç vardır. Bu derlemenin amacı, TDAU kullanımının potansiyel mekanizmalarını ve etki mekanizmalarını tartışmaktır.
Transcranial Direct Current Stimulation: A Review
Transcranial direct current stimulation (TDCS) has been established as a noninvasive tool for modulation of cortical function. It involves the passing of a weak direct electrical current through the cerebral cortex using electrodes placed upon the scalp. TDCS decreases cortical excitability with cathodal or increases excitability with anodal currents. There are few past reports of TDCS to treat psychiatric disorders. However, stimulation with different parameters in different groups of patients needs additional studies. The aim of this review is to discuss the potential mechanisms of action and use of TDCS.
