Objective: To test the hypothesis that lower 25-hydroxyvitamin D [25(OH)D] levels are associated with a greater likelihood of cognitive impairment and risk of cognitive decline.; Methods: We measured 25(OH)D and assessed cognitive function using the Modified Mini-Mental State Examination (3MS) and Trail Making Test Part B (Trails B) in a cohort of 1,604 men enrolled […]

Aim: It remains unknown whether antiplatelet agents have a preventive effect on cognitive decline in patients with Alzheimer’s disease (AD). We investigated the effects of cilostazol, an antiplatelet agent and cyclic adenosine monophosphate phosphodiesterase 3 inhibitor, on cognition and regional cerebral blood flow (rCBF) in elderly patients with AD and cerebrovascular disease (CVD).; Methods: A […]

Background: Depression is a common and costly comorbidity in dementia. There are very few data on the cost-effectiveness of antidepressants for depression in dementia and their effects on carer outcomes.; Aims: To evaluate the cost-effectiveness of sertraline and mirtazapine compared with placebo for depression in dementia.; Method: A pragmatic, multicentre, randomised placebo-controlled trial with a […]
Memantine versus donepezil in mild to moderate Alzheimer’s disease: a randomized trial with magnetic resonance spectroscopy
Modrego, P. J.,
Fayed, N.,
Errea, J. M.,
Rios, C.,
Pina, M. A.,
Sarasa, M.
Background and Purpose: To compare memantine with the most prescribed cholinesterase inhibitor (donepezil) from a clinical viewpoint when administered in early phases of Alzheimer disease (AD), and to find out whether memantine may produce changes in brain metabolite concentrations in comparison with donepezil.; Methods: In this comparative rater-blinded parallel group randomized trial we recruited a […]
Demonstration of safety in Alzheimer’s patients for intervention with an anti-hypertensive drug Nilvadipine: results from a 6-week open label study

Mathura, V.,
Mullan, M.,
Crawford, F.,
Lawlor, B. A.,
Kenny, R. A.
Background: Nilvadipine may lower rates of conversion from mild-cognitive impairment to Alzheimer’s disease (AD), in hypertensive patients. However, it remains to be determined whether treatment with nilvadipine is safe in AD patients, given the higher incidence of orthostatic hypotension (OH) in this population, who may be more likely to suffer from symptoms associated with the […]

Background: Alzheimer’s disease is characterized by the presence of cortical amyloid-beta (Aβ) protein plaques, which result from the sequential action of β-secretase and γ-secretase on amyloid precursor protein. Semagacestat is a small-molecule γ-secretase inhibitor that was developed as a potential treatment for Alzheimer’s disease.; Methods: We conducted a double-blind, placebo-controlled trial in which 1537 patients […]

Background: Depression is common in dementia but the evidence base for appropriate drug treatment is sparse and equivocal. We aimed to assess efficacy and safety of two of the most commonly prescribed drugs, sertraline and mirtazapine, compared with placebo.; Methods: We undertook the parallel-group, double-blind, placebo-controlled, Health Technology Assessment Study of the Use of Antidepressants […]
