Clinical Trials Related to Aricept (Donepezil)
Aricept to Improve Functional Tasks in Vascular Dementia [Recruiting]
Medications for memory improvement are available but they may not actually improve the
ability to do real world tasks. The purpose of this research study is to determine if a
medicine used to treat memory problems donepezil(Aricept) enhances the ability to remember
steps of functional tasks and the actual ability to perform tasks relevant to real-life
independence. Aricept is an FDA approved medication for the treatment of Alzheimer's
disease. Aricept is an investigational drug for the purposes of this study, and is not
approved for this purpose.

The purpose of this study is to evaluate the efficacy and safety of E2020 in patients with
Dementia with Lewy Bodies (DLB).
Efficacy and Safety of Aricept in the Treatment of Severe Alzheimerâs Disease [Completed]
Donepezil hydrochloride (Aricept) has been approved to treat symptoms associated with mild to
moderate Alzheimer’s disease (AD). Aricept has been shown to improve the memory and thinking
abilities, activities of daily living and global function in patients. The purpose of the
study is to further investigate the effectiveness and safety of donepezil in patients with
severe Alzheimer’s disease.
Donepezil is thought to work in the brain by increasing the levels of an important brain
chemical called acetylcholine. This chemical helps a person’s memory to work better.

Aricept review by care giver of 80 year old female patient
|Overall rating:|| || |
|Effectiveness:|| || Ineffective|
|Side effects:|| || Mild Side Effects|
|Condition / reason:|| || Alzheimer's disease|
|Dosage & duration:|| || 10 mg taken once daily for the period of 6 months|
|Other conditions:|| || hernia, teeth problems|
|Other drugs taken:|| || Tamasapan|
|Benefits:|| || We could not identify any benefits at all. The behavior and memory problems remained unchanged or worsened over time. Anxiety continued to increase and the dementia progressed systematically. Disorientation continued to increase and the patient became more and more difficult to manage. It appeared that irritability increased and the patient became more agitated more easily.|
|Side effects:|| || There was some indication that there was at least some increase nausa as well as some infrequent but increased bouts of diarrhea. There were a few episodes of vomiting, but it might be attributed to other factors for this one side effect. There was definitely increased insomnia as well as loss of appetite, but it can not be definitively stated that the drug alone contributed to these although it did occur after the drug was begun.|
|Comments:|| || The patient was given a daily dose. After transfer to a care facility, the regimentation in taking the dose was firmly set in place. Staff medical personnel on site did not observe any benefits, and as a result, after about 6 months the prescription was terminated. During the time the drug was used, there was a patient review every other week to ascertain whether there seemed to be any improvement in the patient. Memory tests were administered and one-on-one interviews were executed by medical personnel. The results of the memory testing showed no net improvement nor was there any identifiable changes that might be considered positive. Ultimately her psychiatrist in consultation with the family decided that the drug did not seem to provide any net gain.|
