Alzheimer Disease
Conditions
Brief summary
The purpose of this study is to determine whether combination of donepezil, a cholinesterase inhibitor, with choline alfoscerate has a more favourable clinical profile than monotherapy with donepezil alone.
Detailed description
Aging population is a characteristic feature of demographic trends in developed countries. Hence, Alzheimer's disease is recognized as one of today's major healthcare challanges, and its significance will increase even more as the longevity of the population increases. Pre-clinical investigations have suggested that association between ChE-Is (cholinesterase inhibitors) and the cholinergic precursor choline alfoscerate enhances cholinergic neurotransmission more effectively than single compounds alone. This clinical trial is designed to assess if combination of the ChE-I donepezil with choline alfoscerate has a more favorable clinical profile than monotherapy with donepezil alone.
