Psikiyatrik hastalıkların tedavisinde psikocerrahi'nin tartışmalı bir geçmişi vardır. Fakat son yıllarda tedavi seçenekleri sınırlı olan dirençli depresyonun (DD) yönetiminde, bazı nöroanotomik hedeşerin kronik derin beyin uyarımı (DBU) ile uyarılma potansiyelini destekleyen deliller mevcuttur. DBU ile ideal klinik sonuca ulaşmak, depresyonun değişken klinik sürecinden sorumlu heterojen sinir döngülerini belirlemeyi ve bu döngülerin içinde uyarılacak düğümleri seçmeyi içerir. Bir dizi heyecan verici ön çalışma DBU'ını depresyonlu hastaların tedavisinde bir kaç farklı beyin bölgesinde kullanmıştır. DBU'nın terapotik etkilerinden sorumlu mekanizmaları hakkında süregiden tartışmalara rağmen, bugüne kadarki klinik sonuçlar bu tekniği DD'da uygun bir tedavi seçeneği olarak güçlü bir şekilde işaret etmektedir. DBU'nın psikiyatri'de ki tam terapotik potensiyeli dikkatli etik yaklaşımlar ve uzun dönem plasebo kontrollü karşılaştırmalara odaklanmış gelecek klinik çalışmalarla açıklanacaktır.
The neurosurgical treatment of depression: Can it supersede psychopharmacology?
Psychosurgery has a controversial history in the treatment of psychiatric disorders, but in recent [year]s there has been mounting evidence for the potential of chronic electrical deep brain stimulation (DBS) of several neuroanatomical targets in managing treatment-resistant depression (TRD), a debilitating mental illness with limited therapeutic options. Achieving optimal clinical outcome with DBS involves characterizing the heterogeneous neuronal circuits responsible for the variable clinical course of depression and selecting nodes within these circuits for stimulation. A number of exciting preliminary studies have used DBS in several discrete brain areas to treat patients with depression. Despite ongoing controversies about the mechanisms responsible for the therapeutic effects of DBS, the clinical results to date show strong promise for this technique as a feasible treatment choice in TRD. The full therapeutic potential of DBS in psychiatric practice will be revealed as future clinical studies focus on careful ethical approaches and the use of long-term placebo controlled comparisons.
