Abstract

Objective: The aim of this study was to use Magnetic Resonance Spectroscopy (MRS) to investigate whether patients with chronic schizophrenia have different brain metabolite levels in the temporal cortex and thalamus than drug-naïve first-episode patients. Method: We compared right-handed male first-episode patients (n=13) and chronic schizophrenic cases (n=15) with gender- and handedness-matched controls (n=10). Right temporal and right thalamic N-Acetylaspartate (NAA)/Creatine (Cre), NAA/Choline (Cho), and Cho/Cre ratios were obtained with MRS. Results: Right temporal NAA/Cre, NAA/Cho, and right thalamus NAA/Cre ratios were significantly lower both in the chronic and first-episode patient groups when compared to normal controls (p<. 001), suggesting decreased neuronal integrity in both patient groups. There were no significant correlations between symptom severity and functional status with MRS variables (p=.027). These results suggested that both patient groups had neural integrity problems. Duration of illness (days) in the first-episode patients was significantly correlated with right temporal NAA/Cre and NAA/Cho. Conclusions: These results suggested that first-episode and chronic patients had significantly impaired neural integrity, particularly in the temporal cortex. It seems that in the acute phase of the first-episode, neural integrity impairment increased along with days elapsed without treatment.

Özet

Amaç: Kronik şizofrenisi olan bireylerle ilk atak, daha önceden ilaç kullanmamış psikotik bireylerin sağ temporal korteks ve talamus metabolit seviyelerinin Manyetik Rezonans Spektroskopi yöntemi ile karşılaştırılmasıdır. Yöntem: Çalışmaya hepsi sağ elini kullanan erkeklerden oluşan üç grup alınmıştır. Gruplar ilk psikoz atağı nedeniyle hastanede yatan hastalar (s:13), akut alevlenme nedeniyle hastanede yatan en az iki yıldır şizofreni tanısı ile izlenen hastalar (s:15) ve sağlıklı gönüllülerden (s:10) oluşmuştur. Bulgular: Sağ temporal NAA/Cre, NAA/Cho ve sağ talamus NAA/Cre oranları hem kronik hem de ilk atak olgularda normal kontrollere göre her iki hasta grubunda da nöral bütünlük bozulması olduğunu düşündürecek şekilde daha düşük olarak bulunmuştur (p<.001). Belirti şiddeti ile MRS değişkenleri arasında bir ilişki bulunmamıştır. İlk atak olgularda hastalığın süresi (gün olarak) ile sağ temporal NAA/Cre ve NAA/Cho değerleri arasında anlamlı ilişki bulunmuştur (p=.027). Tartışma: Bu sonuçlar ilk atak olgularda, kronik olgularda olduğu gibi, özellikle sağ temporal kortekste nöral bütünlük bozulması olduğunu göstermektedir. Bulgular ilk atağın akut döneminde, tedavisiz geçen günler ile nöral bütünlük bozulması arasında ilişki olduğunu düşündürmektedir.
