Abstract—The main purpose of this study was to evaluate whether donepezil and Low-Level Light Therapy (LLLT) shown to play neuroprotective effects by stimulating mitochondrial activity in the amyloid-beta 1-42 (Aβ1-42) -induced neuronal toxicity model of Alzheimer’s Disease (AD). This result indicates that the Aβ1-42 accumulation in neuronal cells is related to the mitochondrial dysfunction and induced-neuronal cell death. While donepezil and Low-Level Light Therapy (LLLT; 660 nm, 5mW/cm2, 3J/ cm2) can reverse this situation. Donepezil is therapeutic acetylcholinesterase inhibitor currently being used for the treatment of AD. SH-SY5Y cells were pre-treated by donepezil at a concentration of 1 µM showed a maximum of neuronal viability compared to control cells. However, at higher concentrations, the neuronal viability was diminished. LLLT is a noninvasive therapy which showed significant increasing of neuronal viability and afforded protection against Aβ1-42-induced toxicity. In addition, the combination treatment between 1 µM of donepezil pre-treatment and LLLT in SH-SY5Y cells induced by Aβ1-42 toxicity had increased cell viability. In aggregate, these results demonstrate that LLLT has probably contributed to alternative treatment in neurodegenerative disease.
