Background: Considering the high prevalence of dementia, it would be of great value to develop effective tools to improve cognitive function. We examined the effects of a human-type communication robot on cognitive function in elderly women living alone.; Material/methods: In this study, 34 healthy elderly female volunteers living alone were randomized to living with either […]

Lozano, Andres M.
Background: The importance of developing unique, neural circuitry-based treatments for the cognitive and neuropsychiatric symptoms of Alzheimer disease (AD) was the impetus for a phase I study of deep brain stimulation (DBS) in patients with AD that targeted the fornix.; Objective: To test the hypotheses that DBS would increase cerebral glucose metabolism in cortical and […]
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 […]

Gonadal hormones may influence cognitive function. Postmenopausal midlife women in the population-based Melbourne Women’s Midlife Health Project cohort were administered a comprehensive battery of neuropsychological tests on two occasions 2 years apart. Participants (n = 148, mean age 60 years) had undergone natural menopause and were not using hormone therapy. Estrone, total and free estradiol, […]

Background: Gantenerumab is a fully human anti-Aβ monoclonal antibody in clinical development for the treatment of Alzheimer disease (AD).; Objectives: To investigate whether treatment with gantenerumab leads to a measurable reduction in the level of Aβ amyloid in the brain and to elucidate the mechanism of amyloid reduction.; Design: A multicenter, randomized, double-blind, placebo-controlled, ascending-dose […]
Greater responsiveness to donepezil in Alzheimer patients with higher levels of acetylcholinesterase based on attention task scores and a donepezil PET study

Iwata, Ren,
Yanai, Kazuhiko
The aim of the study was to predict donepezil responders among patients with Alzheimer disease (AD) based on cognitive tests and positron emission tomography. The Mini-Mental State Examination, Digit Symbol subtest (DigSm) of Wechsler Adult Intelligence Scale Revised, and Trail-Making Test A were administered for 80 patients with AD to assess global function, attention, and […]
