Abstract

Cognitive impairments are pervasive among populations with traumatic brain injury and cerebral vascular accidents. Given the limited effectiveness of behavioral approaches in treating cognitive impairments, the use of non-invasive brain stimulation and modulation methods have been increasingly explored over the past decade. The present article reviews recent evidence on the use of two non-invasive technologies, transcranial magnetic stimulation and transcranial direct current stimulation on populations with brain injury and stroke. The results indicate that although evidence for the use of neuromodulation for cognitive enhancement in neurotypical adults is somewhat positive, its use in disordered populations is less promising. Few studies demonstrated positive effects of neuromodulation on cognitive measures. Importantly, most results are confounded by behavioral interventions and the effects are highly variable. More research is needed to evaluate the therapeutic potential of non-invasive brain stimulation techniques when used in isolation for remediation of cognitive impairments associated with various neurologic conditions. Larger clinical trials with strong methodologic rigor including double-blind randomized control trials are necessary to validate the use of these methods for translational implementation. Given the conflicting evidence base that presently exists, when neuromodulation techniques are employed, they should be used with cognitive and physical therapies that are given precedence.

Özet

Kognitif bozukluklar, özellikle travmatik beyin hasarı ve serebrovasküler olay geçirmiş bireylerde yaygındır. Kognitif bozuklukların tedavisinde, rehabilitasyon yaklaşımlarının etkinliği sınırlıdır. Bu alanda son on yılda, invaziv olmayan beyin stimülasyonu ve modülasyon yöntemlerinin kullanımı giderek daha fazla artmıştır. Bu makale, iki invaziv olmayan teknolojinin, transkraniyal manyetik stimülasyonun ve transkraniyal doğru akım stimülasyonunun beyin hasarı ve inme geçirmiş olan popülasyonlarda kullanımına ilişkin son çalışmaları ve kanıtları gözden geçirmektedir. Sonuçlar, nörotipik yetişkinlerde kognitif gelişim için nörostimülasyon kullanımına yönelik kanıtların daha pozitif olduğunu, kaza veya inme geçirmiş popülasyonlarda ise kullanımının yeterince sonuç veremediğini göstermektedir. Literatürde, nörostimülasyonun kognitif ölçütler üzerindeki olumlu etkisini ortaya koyan kısıtlı sayıda çalışma vardır. Sonuçların birçoğu, rehabilitatif müdahalelerle karıştırılmaktadır ve etkileri oldukça değişkendir. İnvaziv olmayan beyin stimülasyon tekniklerinin, kognitif bozuklukların giderilmesinde, tek başına kullanıldığında terapotik potansiyelini değerlendirmek için daha fazla araştırmaya ihtiyaç olduğu bir gerçektir. Çift-kör randomize kontrollü araştırmalar da dahil olmak üzere güçlü metodolojisi olan daha büyük klinik deneyler, bu yöntemlerin translasyonel uygulama için kullanımını doğrulamak için gereklidir. Çelişkili kanıt temeli göz önüne alındığında, nörostimülasyon teknikleri kullanıldığında öncelik kognitif ve fiziksel tedavilere verilmelidir.
