Dementia Care Practice.

Alzheimer's disease significantly impacts decision-making abilities, potentially increasing risk-taking behaviors and complicating the process of aging-in-place, particularly in cases of anosognosia (self-awareness impairment). To understand how this affects patient and caregiver perspectives, we conducted a qualitative study to identify arguments used by older patients with Alzheimer's disease and their family caregivers about aging-in-place. We included 18 dyads, each comprising an older adult living at home with mild dementia and their family caregiver.

[Willingness to age in place and anosognosia of risks in Alzheimer's disease].

Alzheimer's disease leads to an alteration of decision-making abilities which may increase risk-taking behaviours, particularly associated anosognosia. Anticipating the progression of the disease raises a number of questions, particularly in relation to aging in place. Our qualitative study aimed to identify the arguments used by older patients with Alzheimer's disease when choosing a place to age.

Adaptations of the balloon analog risk task for neuroimaging settings: a systematic review.

Introduction: The Balloon Analog Risk Task (BART), a computerized behavioral paradigm, is one of the most common tools used to assess the risk-taking propensity of an individual. Since its initial behavioral version, the BART has been adapted to neuroimaging technique to explore brain networks of risk-taking behavior. However, while there are a variety of paradigms adapted to neuroimaging to date, no consensus has been reached on the best paradigm with the appropriate parameters to study the brain during risk-taking assessed by the BART.

Tools for the Assessment of Risk-Taking Behavior in Older Adults with Mild Dementia: A Cross-Sectional Clinical Study.

Diseases such as Alzheimer's cause an alteration of cognitive functions, which can lead to increased daily risk-taking in older adults living at home. The assessment of decision-making abilities is primarily based on clinicians' global analysis. Usual neuropsychological tests such as the MoCA (Montreal Cognitive Assessment) cover most of the cognitive domains and include mental flexibility tasks.

Towards a Functional Neuromarker of Impulsivity: Feedback-Related Brain Potential during Risky Decision-Making Associated with Self-Reported Impulsivity in a Non-Clinical Sample.

Risk-taking is part of the multidimensional nature of impulsivity, consisting of an active engagement in behaviors or choices with potentially undesirable results, with probability as the cost for an expected reward. In order to understand the neurophysiological activity during risky behavior and its relationship with other dimensions of impulsivity, we have acquired event-related-potential (ERP) data and self-reported impulsivity scores from 17 non-clinical volunteers. They underwent high-resolution electroencephalography (HR-EEG) combined with an adapted version of the Balloon Analogue Risk Task (BART), and completed the Barratt Impulsiveness Scale (BIS-10) and the Urgency, Premeditation, Perseverance, Sensation Seeking, Impulsive Behavior Scale (UPPS).
