Telomere shortening in elderly individuals with mild cognitive impairment may be attenuated with ω-3 fatty acid supplementation: a randomized controlled pilot study
Objectives: Excessive shortening of the telomeric ends of chromosomes is a marker of accelerated aging. Oxidative stress and nutritional deficiency may influence this process. The aim of this study was to investigate the effect of ω-3 polyunsaturated fatty acid (ω-3 PUFA) supplementation on telomeric shortening in elderly individuals with mild cognitive impairment (MCI).; Methods: Thirty-three […]

The impact of supplemental macular carotenoids in Alzheimer’s disease: A randomized clinical trial
Background: Patients with Alzheimer’s disease (AD) exhibit significantly less macular pigment (MP) and poorer vision when compared to control subjects. Objective: To investigate supplementation with the macular carotenoids on MP, vision, and cognitive function in patients with AD versus controls. Methods: A randomized, double-blind clinical trial with placebo and active arms. 31 AD patients and […]

The safety, tolerability, pharmacokinetics and cognitive effects of GSK239512, a selective histamine H₃ receptor antagonist in patients with mild to moderate Alzheimer’s disease: a preliminary investigation
Background: The histamine H3 receptor plays a critical role in the negative neuromodulation of neurotransmitters involved in cognitive function. H3 receptor antagonists/inverse agonists have been shown to exert pro-cognitive effects in pre-clinical models. GSK239512 is a potent and selective H₃ receptor antagonist developed for the treatment of cognitive dysfunction in neurodegenerative disorders. In this study […]

Efficacy of musical interventions in dementia: evidence from a randomized controlled trial
Although musical interventions have recently gained popularity as a non-pharmacological treatment in dementia, there is still insufficient evidence of their effectiveness. To investigate this issue, a single-center randomized controlled trial was conducted with forty-eight patients with Alzheimer’s disease or mixed dementia to compare the effects of music versus cooking interventions in the emotional, cognitive, and […]

Efficacy and safety of memantine in patients with moderate-to-severe Alzheimer’s disease: results of a pooled analysis of two randomized, double-blind, placebo-controlled trials in Japan
Background: With the increase in the aging population, there is a pressing need to provide effective treatment options for individuals with Alzheimer’s disease (AD). Memantine is an N-methyl-D-aspartate receptor antagonist used to treat AD in > 80 countries worldwide, and studies in the USA and Europe have shown it to be effective in improving language […]

Chronic endurance exercise training prevents aging-related cognitive decline in healthy older adults: A randomized controlled trial
Objective: To evaluate the effects of endurance exercise training (EET) on the cognitive status of healthy community-dwelling older adults. Methods: A randomized controlled trial was conducted involving community-dwelling older adults from the town of Pianoro (northern Italy). We randomized 120 healthy subjects aged 65–74 years, both genders, to treatment (N = 60) and control (N […]

Cognitive-motor intervention in Alzheimer’s disease: Long-term results from the Maria Wolff trial
Background: Little is known about the long-term acceptance and effects of cognitive and motor stimulation interventions (CMSI) in Alzheimer’s disease (AD). Objective: To evaluate a replicable CMSI program for mild cognitive impairment (MCI) and mild-to-moderate AD persons. Methods: Eighty-four non-institutionalized subjects with AD were randomized to receive either CMSI, administered by a single care provider, […]

Foot massage and physiological stress in people with dementia: A randomized controlled trial
Background: The anxiety associated with unfamiliar surroundings, the disorientation and mental confusion, and the social isolation that accompanies dementia can often create increased stress for people living in long-term care settings. Such a response is thought to affect the autonomic nervous system and result in emotional and physical symptoms of distress that may be manifested […]

Foot massage versus quiet presence on agitation and mood in people with dementia: A randomised controlled trial
Background: There is increasing interest in using complementary and alternative treatments to manage behavioural and psychological symptoms of dementia such as agitation, aggression and depressed mood. Objective: To compare the effect of foot massage (intervention) and quiet presence (control) on agitation and mood in people with dementia. Design: A randomised controlled trial using a within-subjects, […]

Exploring the effect of companion robots on emotional expression in older adults with dementia: a pilot randomized controlled trial
This pilot study aimed to compare the effect of companion robots (PARO) to participation in an interactive reading group on emotions in people living with moderate to severe dementia in a residential care setting. A randomized crossover design, with PARO and reading control groups, was used. Eighteen residents with mid- to late-stage dementia from one […]
