Abstract
Aims
To elucidate the efficacy of galantamine on cognition and behavioral and psychological symptoms of dementia (BPSD) in outpatients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) who have switched from donepezil to galantamine.
Materials and Methods
We performed an uninterrupted switch from donepezil to galantamine without a washout period or dose titration in 44 ambulatory outpatients with amnestic MCI (n = 12) or mild-to-moderate AD (n = 32). Three months after the switch, the efficacy of galantamine was evaluated with the Mini-Mental State Examination (MMSE), and the Neuropsychiatric Inventory (NPI) and NPI Brief Questionnaire Form (NPI-Q), respectively, using the Wilcoxon signed-rank test.
Results
NPI scores improved significantly on BPSD, especially on delusions, agitation and aberrant motor activity in AD patients (p = 0.027); improvement was remarkable in patients with moderate AD (MMSE score 10-19; p = 0.007), while insignificant in those with MCI (MMSE score ≥24; p = 0.648). The NPI-Q score also improved significantly regarding both the severity of the disease (p = 0.009) and caregiver distress (p = 0.012) in AD patients. MMSE scores hardly improved in either MCI (p = 0.394) or AD patients (p = 0.265).
Conclusions
An uninterrupted switch from donepezil to galantamine could be a useful alternative treatment option for AD patients whose BPSD are unresponsive to donepezil, or whose caregivers are not satisfied with donepezil treatment.
