Arms Assigned Interventions
Experimental: high dose donepezil (23mg)
Patients with dementia in Parkinson's disease, who are treated with high dose donepezil (23mg)
Drug: Donepezil
23mg/day for 24 weeks versus 10mg/day for 24 weeks
Other Name: aricept
Active Comparator: standard dose denepezil (10mg)

Detailed Description:
This study is open-label, prospective, randomized paralleled study. The investigators evaluate the efficacy of high-dose donepezil in patients with Parkinson's disease with dementia (PDD) who have taken standard donepezil (10mg) for 12 weeks. The participants, who sign the informed consent, are assigned into two groups randomly (high-dose donepezil group and standard donepezil group). All participants will be maintained the medication for 24 weeks and assessed cognitive function at 24 weeks. They will visit to clinic for 3 times (4, 12, 24 weeks) to assess cognitive function and adverse event. After the end of study, all participants were administrated by standard dose donepezil again.

Ages Eligible for Study:   50 Years to 80 Years   (Adult, Senior)
