Treatment effects of therapeutic cholinesterase inhibitors on visuospatial processing in Alzheimer’s disease: A longitudinal functional MRI study
Thiyagesh, Subha N.,
Farrow, Tom F. D.,

Hunter, Michael D.,

Wilkinson, lain D.,
Woodruff, Peter W. R.
Background/Aims: Visuospatial impairments are known to occur in Alzheimer’s disease (AD). We hypothesised that functional magnetic resonance imaging (fMRI) response in task-related brain regions would be impaired in patients with AD during the task and that treatment with acetyl cholinesterase inhibitors would enhance activations in brain regions concerned with this visual perceptual processing. Method: Ten […]
Estimation and validation of a multiattribute model of Alzheimer disease progression
Stallard, Eric,
Kinosian, Bruce,
Zbrozek, Arthur S.,
Yashin, Anatoliy I.,
Glick, Henry A.,
Stern, Yaakov
Objectives: To estimate and validate a multiattribute model of the clinical course of Alzheimer disease (AD) from mild AD to death in a high-quality prospective cohort study, and to estimate the impact of hypothetical modifications to AD progression rates on costs associated with Medicare and Medicaid services. Data and Methods: The authors estimated sex-specific longitudinal […]
Evaluating rivastigmine in mild-to-moderate Parkinson’s disease dementia using ADAS-cog items

Rivastigmine has been shown to improve cognition in patients with Parkinson’s disease dementia (PDD). To further explore the impact of anticholinesterase therapy on PDD, Alzheimer’s Disease Assessment Scale—cognitive subscale (ADAS-cog) items were assessed in a retrospective analysis of a 24-week, double-blind, placebo-controlled trial of rivastigmine. Mean changes from baseline at week 24 were calculated for […]
How to manage overactive bladder in elderly individuals with dementia? A combined use of donepezil, a central acetylcholinesterase inhibitor, and propiverine, a peripheral muscarine receptor antagonist

Although urinary incontinence inevitably occurs in advanced stages of dementia of any etiology, urinary urgency or frequency, also called an overactive bladder (OAB), occurs more commonly in dementia with Lewy bodies (DLB) and vascular dementia than it does in Alzheimer’s disease (AD). Acetylcholinesterase (AChE) inhibitors for dementia and anticholinergics for OAB have been widely used, […]
Reducing dangerous nighttime events in persons with dementia by using a nighttime monitoring system
Rowe, Meredeth A.,

Horne, Claydell,
Lane, Steve,
Campbell, Judy,
Lehman, Brandy,
Phipps, Chad,
Keller, Meredith,
Pe Benito, Andrea
Background: Nighttime activity, a common occurrence in persons with dementia, increases the risk for injury and unattended home exits and impairs the sleep patterns of caregivers. Technology is needed that will alert caregivers of nighttime activity in persons with dementia to help prevent injuries and unattended exits. Methods: As part of a product development grant, […]
No effect of donepezil on striatal dopamine release in mild to moderate Alzheimer’s disease
Objective: Work in experimental animals suggests that an interaction with dopaminergic networks might explain some of the therapeutic effects of the cholinesterase inhibitor class of drugs. This study aimed to test whether acute (single 5 mg) or 4–8 weeks (5–10 mg) of treatment with oral donepezil would elicit measurable striatal dopamine (DA) release in patients […]
A serum protein-based algorithm for the detection of Alzheimer disease

Objective: To develop an algorithm that separates patients with Alzheimer disease (AD) from controls. Design: Longitudinal case-control study. Setting: The Texas Alzheimer’s Research Consortium project. Patients: We analyzed serum protein-based multiplex biomarker data from 197 patients diagnosed with AD and 203 controls. Main Outcome Measure: The total sample was randomized equally into training and test […]
