Alzheimer's disease (AD) is a serious multifactorial disorder with progressive neurodegenerative outcomes related with impaired redox homeostasis. Inhibition of the enzyme acetylcholinesterase (AChE), as one of the major therapeutic strategies, is considered to be offering only symptomatic relief and moderate disease modifying effect. We intended to investigate the effects of acetylcholinesterase inhibition via donepezil on protein carbonyl (PCO), advanced protein oxidation products (AOPP) and ischemia modified albumin (IMA) as protein oxidation markers and ferric reducing antioxidant power (FRAP), prooxidant-antioxidant balance (PAB), total thiol (T-SH), protein thiol (P-SH) as antioxidant status markers and also kynurenine (KYN), N-formyl kynurenine (N-FKYN) and protein bound dityrosine (DT) levels all in one demonstrating the redox homeostasis in Alzheimer patients also correlated with AChE activity.

Methods: A total of 38 patients with Alzheimer's disease (AD) and 34 sex- and age-matched mentally healthy control subjects were included in this study.
Results: The patients had significantly higher AOPP, IMA and PAB in the patient group than in the control group (P = 0.
