Omega-3 fatty acid supplementation effects on weight and appetite in patients with Alzheimer’s disease: the omega-3 Alzheimer’s disease study

Objectives: To study the effects of omega (Omega)-3 fatty acid (FA) supplements on weight and appetite in patients with mild to moderate Alzheimer’s disease (AD) in relation to inflammatory biomarkers and apolipoprotein E epsilon4 (APOEepsilon4).; Design: Randomized, double-blind, placebo-controlled trial.; Setting: Specialist memory clinics in the Stockholm catchment area.; Participants: Two hundred four patients (aged […]

Safety, tolerability, and efficacy of PBT2 in Huntington’s disease: A phase 2, randomised, double-blind, placebo-controlled trial

Background: PBT2 is a metal protein-attenuating compound that might reduce metal-induced aggregation of mutant huntingtin and has prolonged survival in a mouse model of Huntington’s disease. We aimed to assess the safety, tolerability, and efficacy of PBT2 in patients with Huntington’s disease. Methods: In this 26-week, randomised, double-blind, placebo-controlled trial, adults (≥ 25 years old) […]

A randomized, double-blind, placebo-controlled trial of memantine in a behaviorally enriched sample of patients with moderate-to-severe Alzheimer’s disease

Background: Agitation and aggression in Alzheimer’s disease (AD) are amongst the most serious of neuropsychiatric symptoms, and contribute to poor outcomes and worse quality of life. Previous studies have suggested a benefit for memantine on agitation and aggression, but none have examined its efficacy in community-dwelling patients with significant agitation and aggression at baseline, utilizing […]

Subjective stressors moderate effectiveness of a multi-component, multi-site intervention on caregiver depression and burden

Objectives: The present study assessed whether caregiving contextual factors moderated outcomes of a caregiver intervention.; Methods: Extant data from the Resources for Enhancing Alzheimer’s Caregiver Health (REACH) II study, a randomized-control trial of a multi-component, multi-site intervention for dementia caregivers was utilized. 498 caregivers {83.1% women; mean [standard deviation (SD)] age = 60.3 (13.1)}, and their care […]

Antihypertensive therapy and cerebral hemodynamics in executive mild cognitive impairment: results of a pilot randomized clinical trial

Objectives: To compare the effects of three antihypertensive medications on cerebral hemodynamic and cognitive function in hypertensive individuals with executive dysfunction.; Design: Double-blind randomized clinical trial.; Setting: Community.; Participants: Fifty-three individuals aged 60 and older with hypertension and executive dysfunction.; Intervention: Lisinopril, candesartan, or hydrochlorothiazide for 1 year.; Measurements: Cerebral blood flow velocity (BFV; transcranial […]

Doxycycline in Creutzfeldt-Jakob disease: a phase 2, randomised, double-blind, placebo-controlled trial

Background: Creutzfeldt-Jakob disease (CJD) is a fatal, untreatable prion encephalopathy. Previous studies showed that doxycycline is effective in in-vitro and in-vivo models of disease, and patients with CJD who received compassionate treatment with doxycycline showed increased survival time compared with historical series. We therefore did a randomised, double-blind study of doxycycline versus placebo in CJD.; […]
