The interplay of age, gender and amyloid on brain and cognition in mid-life and older adults.

Deficits in memory are seen as a canonical sign of aging and a prodrome to dementia in older adults. However, our understanding of age-related cognition and brain morphology occurring throughout a broader spectrum of adulthood remains limited. We quantified the relationship between cognitive function and brain morphology (sulcal width, SW) using three cross-sectional observational datasets (PISA, AIBL, ADNI) from mid-life to older adulthood, assessing the influence of age, sex, amyloid (Aβ) and genetic risk for dementia.

Can an online battery match in-person cognitive testing in providing information about age-related cortical morphology?

Clinical identification of early neurodegenerative changes requires an accurate and accessible characterization of brain and cognition in healthy aging. We assessed whether a brief online cognitive assessment can provide insights into brain morphology comparable to a comprehensive neuropsychological battery. In 141 healthy mid-life and older adults, we compared Creyos, a relatively brief online cognitive battery, to a comprehensive in person cognitive assessment.

A central role of sulcal width in the associations of sleep duration and depression with cognition in mid to late life.

Study Objectives: Evidence suggests that poor sleep impacts cognition, brain health, and dementia risk but the nature of the association is poorly understood. This study examined how self-reported sleep duration, napping, and subjective depression symptoms are associated with the brain-cognition relationship in older adults, using sulcal width as a measure of relative brain health.

Methods: A canonical partial least squares analysis was used to obtain two composite variables that relate cognition and sulcal width in a cross-sectional study of 137 adults aged 46-72.

Pre-attentive and Attentive Auditory Event-related Potentials in Children With Attention-Deficit Hyperactivity Disorder and Autism.

Abnormalities in auditory processing are believed to play a major role in autism and attention-deficit hyperactivity disorder (ADHD). Both conditions often co-occur in children, causing difficulties in deciding the most promising intervention. Event-related potentials (ERPs) have been investigated and are showing promise to act as potential biomarkers for both conditions.

Effectiveness of information and communications technology interventions for stroke survivors and their support people: a systematic review.

Purpose: To examine the effectiveness of self-directed, off-the-shelf information and communications technology (ICT)-based interventions in improving the quality of life, physical and psychosocial outcomes of community-dwelling stroke survivors and their support persons (SP).

Methods: Medline, EMBASE, CINAHL and Cochrane databases were searched (2006-19th June 2020) for randomized controlled trials, controlled trials, controlled before and after studies, or interrupted time series studies that met the eligibility criteria. The quality of included studies was assessed.
