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 […]
Hormone levels and cognitive function in postmenopausal midlife women
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, […]
Midlife alcohol consumption and later risk of cognitive impairment: a twin follow-up study

Alcohol consumption data was obtained with structured questionnaires in 1975 and 1981, and subjects were contacted between 1999 and […]
