Primary Outcome Measures:
  • Clinician's Interview Based Impression of Change-Plus Caregiver Input (CIBIC-Plus). [ Time Frame: 6,12,18, 24 weeks. ]

Secondary Outcome Measures:
  • Vascular Dementia Assessment Scale cognitive subscale (VaDAS-cog). [ Time Frame: 6,12,18, 24 weeks. ]

Enrollment: 36
Study Start Date: September 2005
Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Drug: donepezil hydrochloride (Aricept)
5 mg donepezil HCl given once a day and increased to 10 mg per day if side effects, when present, are tolerated.
Other Name: Aricept

Detailed Description:
Vascular dementia is a significant cause of intellectual and functional impairment in young patients consequent to cerebrovascular disease. Post-mortem studies show that VaD patients have a cholinergic deficiency like in Alzheimer's disease (AD). Cholinesterase inhibitors are now standard treatment for mild to moderate AD. This study aims to determine if donepezil, a cholinesterase inhibitor, would benefit patients with VaD by decreasing their scores in the VaDAS-cog and improvement in their CIBIC rating over a period of 24-weeks treatment. Adverse events will also be monitored.

Ages Eligible for Study:   40 Years to 60 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

The subjects eligible for this study are men and women outpatients, age 40-60 years old, who fulfill the criteria for VAD according to the National Institute of Neurological Disorders and Stroke and the Association Internationale pour la Recherche et l'Enseignement en Neurosciences International Workshop (NINCDS-AIREN). Subjects shall undergo extensive clinical examination by a stroke specialist and radiological examination (CT or MRI) to document presence of cerebrovascular disease. The clinical diagnosis has to be relevant to the imaging findings.

Other Inclusion criteria:

Subjects with clinically stable hypertension, diabetes mellitus, and cardiac disease for the last 3 months. Subjects with history of recent stroke, who have not been hospitalized for stroke in the previous 3 months. Subjects with depression controlled with medications. Subjects should have no hearing or visual impairment and live with a reliable caregiver.

Exclusion criteria:

Subjects should have no radiological evidence of other brain disorders (subdural hematoma, post-traumatic / post-surgery) have no depression or other psychiatric disorders, infectious disorders, neoplastic condition, and metabolic and toxic encephalopathies, dementia due to AD or prior diagnosis of AD, and major depression or other psychiatric disorders.

Subjects with clinical evidence of pulmonary, hepatic, gastrointestinal, metabolic, endocrine or other life threatening diseases; pregnancy, history of alcohol or drug abuse, and sensitivity to cholinesterase inhibitors; use of investigational agents, cholinomimetic and anticholinergic agents.
