Wavelet coherence model for diagnosis of Alzheimer disease
This article presents a wavelet coherence investigation of electroencephalograph (EEG) readings acquired from patients with Alzheimer disease (AD) and healthy controls. Pairwise electrode wavelet coherence is calculated over each frequency band (delta, theta, alpha, and beta). For comparing the synchronization fraction of 2 EEG signals, a wavelet coherence fraction is proposed which is defined as […]
Does a multicomponent exercise program improve dual-task performance in amnestic mild cognitive impairment? A randomized controlled trial

Uemura, Kazuki,
Suzuki, Takao
Background and Aims: There has been much interest in exercise interventions as a primary behavioral prevention strategy against cognitive decline. The aim of this study was to evaluate the effect of a multicomponent exercise program on physical and dual-task performances in community-dwelling older adults with amnestic mild cognitive impairment (aMCI).; Methods: Fifty older adults (23 […]
Memory and communication support strategies in dementia: effect of a training program for informal caregivers

Pachana, Nancy A.,
Humphreys, Michael S.,
Byrne, Gerard J.,
Chenery, Helen J.
Background: People with dementia have a range of needs that are met by informal caregivers. A DVD-based training program was developed using research-based strategies for memory and communication in dementia. The effectiveness of the training on the caregiver experience and the well-being of the person with dementia was evaluated.; Methods: A pre-test/post-test controlled trial was […]
Effects of lexical-semantic treatment on memory in early Alzheimer disease: an observer-blinded randomized controlled trial
Jelcic, Nela,
Cagnin, Annachiara,
Meneghello, Francesca,
Turolla, Andrea,
Ermani, Mario,
Dam, Mauro
Background: Episodic memory and semantic abilities deteriorate early in Alzheimer disease (AD). Since the cognitive system includes interconnected and reciprocally influenced neuronal networks, the authors hypothesized that stimulation of lexical-semantic abilities may benefit semantically structured episodic memory.; Objective: To investigate the effects of lexical-semantic stimulation (LSS) on verbal communication and episodic memory in early AD.; […]
Serotonergic function and treatment of behavioral and psychological symptoms of frontotemporal dementia
Herrmann, Nathan,
Black, Sandra E.,
Chow, Tiffany,
Cappell, Jaclyn,
Tang-Wai, David F.,
Lanctôt, Krista L.
Objectives: The purposes of this study were first, to evaluate the effectiveness of citalopram in treating behavioral disturbances in frontotemporal dementia (FTD) subjects and second, to determine whether an association exists between serotonergic function, as determined by a neuroendocrine challenge, and treatment response.; Design: Single-dose citalopram (30 mg per os) challenge followed by a 6-week […]
Mnemonic strategy training improves memory for object location associations in both healthy elderly and patients with amnestic mild cognitive impairment: a randomized, single-blind study
Hampstead, Benjamin M.,
Sathian, Krish,
Phillips, Pamela A.,
Amaraneni, Akshay,
Delaune, William R.,
Stringer, Anthony Y.
Objective: To evaluate the efficacy of mnemonic strategy training versus a matched-exposure control condition and to examine the relationship between training-related gains, neuropsychological abilities, and medial temporal lobe volumetrics in patients with amnestic mild cognitive impairment (aMCI) and age-matched healthy controls.; Method: Twenty-three of 45 screened healthy controls and 29 of 42 screened patients with […]
A proteomics study reveals a predominant change in MaoB expression in platelets of healthy volunteers after high protein meat diet: relationship to the methylation cycle
Zellner, Maria,
Babeluk, Rita,
Jakobsen, Lene H.,
Gerner, Christopher,
Umlauf, Ellen,
Volf, Ivo,
Roth, Erich,
Kondrup, Jens
Studies investigating the impact of high meat intake on cognition have yielded contradictory results as some show improved cognitive performance, whereas others report an increase of risk factors for dementia. However, few studies were designed to directly assess the effect of a high protein (HP) diet on both cognitive performance and corresponding biochemical parameters. A […]
The costs and benefits of an integrated approach to dementia
Wolfs, C. A. G.,
Dirksen, C. D.,
Severens, J. L.,
Kessels, A.,
Verkaaik, M.,
Verhey, F. R. J.
Background: An integrated approach to dementia is generally recommended because no one discipline is adequately equipped it deal with the complex psychic, physical and social problems that are inherent in dementia. A multidisciplinary approach, however, leads inevitably to higher costs. It is not known what the cost/benefit ratio will be.; Aim: To describe our research […]
