White matter integrity and lack of insight in schizophrenia and schizoaffective disorder

Abstract: Objective Poor insight into illness is commonly associated with schizophrenia and has implications for the clinical outcome of the disease. A better understanding of the neurobiology of these insight deficits may help the development of new treatments targeting insight. Despite the importance of this issue, the neural correlates of insight deficits in schizophrenia remain poorly understood. Method Thirty-six individuals diagnosed with schizophrenia or schizoaffective disorder underwent diffusion tensor imagi… Show more

“…[14][15][16] So far, studies have mainly used structural imaging, 15,[17][18][19][20][21][22][23] and more rarely functional imaging. 17,24 Lack of insight in patients with schizophrenia frequently has been associated with impairment of the prefrontal cortex, 14,[18][19][20] tempor al areas [15][16][17] and precuneus. 15,19 Interestingly, it has been suggested that a network associating these regions is involved in experiencing consciousness and self-awareness in healthy individuals.…”

“…15,19 Interestingly, it has been suggested that a network associating these regions is involved in experiencing consciousness and self-awareness in healthy individuals. 25, 26 Yet, studies on schizophrenia have specifically focused on impaired insight in correlation analyses 14 or in comparison studies between patients with impaired insight and healthy controls. 18,[20][21][22] Scarce data are available regarding the functional neural substrate of preserved insight in patients with schizophrenia.…”

“…26,29 Çalışmamızda iç görüsüz şizof-reni hastalarının retina katman kalınlıklarını, iç görüsü olan şizofreni hastalarına ve kontrol grubuna göre daha ince saptadık. Şizofrenide klinik belirtilerin, retina katmanlarının kalınlıkları üzerine etkili olabileceği bildirilmiştir.…”

“…2,24,25 Araştırmalar şizofrenide iç görüşüz-lüğün nöropatolojik bir alt yapısının olduğunu göstermesine rağmen, ilgili sinirsel devre tam olarak anlaşılamamıştır. 26 İç görüsüz şizofreni hastalarında yapılan görüntüleme çalışmaların-da, MSS'de yaygın nöronal dejenerasyon, sağ insulada kortikal incelme, temporal ve parietal gri madde hacminde azalma, frontotemporal beyaz cevher hacminde azalma, prefrontal, temporal ve serebellar nörodejenerasyonların olduğu bildirilmiştir. [26][27][28][29][30] İç görüsüzlüğün kliniğe olan olumsuz etkileri nedeniyle MSS düzeneklerinin anlaşılması önemlidir.…”
