The Impact of Dual-Tasks and Disease Severity on Posture, Gait, and Functional Mobility among People Living with Dementia in Residential Care Facilities: A Pilot Study.

Gait speed and timed-up-and-go (TUG) predict cognitive decline, falls, and mortality. Dual-tasks may be useful in cognitive screening among people living with dementia (PWD), but more evidence is needed. This cross-sectional study aimed to compare single- and dual-task performance and determine the influence of dementia severity on dual-task performance and interference. Thirty PWD in two residential care facilities (Age: 81.3 ± 7.1 years; Montreal Cognitive Assessment: 10.4 ± 6.0 points) completed two trials of single- (feet apart) and dual-task posture (feet apart while counting backward), single- (walk 4 m) and dual-task gait (walk 4m while naming words), and single- (timed-up-and-go (TUG)), and dual-task functional mobility (TUG while completing a category task) with APDM inertial sensors. Dual-tasks resulted in greater sway frequency, jerk, and sway area; slower gait speed; greater double limb support; shorter stride length; reduced mid-swing elevation; longer TUG duration; reduced turn angle; and slower turn velocity than single-tasks (ps < 0.05). Dual-task performance was impacted (reduced double limb support, greater mid-swing elevation), and dual-task interference (greater jerk, faster gait speed) was related to moderate-to-severe compared to mild PWD. Moderate-to-severe PWD had poorer dynamic stability and a reduced ability to appropriately select a cautious gait during dual-tasks than those with mild PWD, indicating the usefulness of dual-tasks for cognitive screening.

A Moratorium on the Euphemism MAID.

It is essential for high-quality health care for providers to adhere to the principle of truth telling, speaking with clarity and honesty. The euphemism medical aid in dying, MAID, is being mainstreamed in the medical literature by proponents of physician-assisted suicide and euthanasia. This trend is deleterious because MAID's proponents do not consistently express the meaning and intent of the practice, and the phrase downplays the fact that a provider is participating in the act of death for a patient. The euphemism blurs the differences between providing high-quality palliative care and participating in the death of a patient prior to a natural death. Some believe the term MAID is used exclusively for assisted suicide in patients with a terminal diagnosis with less than 6 months to live, when in fact it is being used for both assisted suicide and euthanasia and for patients who have no terminal diagnosis with potentially years to live. We are calling up on our colleagues to cease the use of this and other euphemisms in this ethically controversial practice. We recommend standardized language that accurately denotes the context and process. Provider Assisted Death by Prescription (PAD-P) and Provider Assisted Death by Administration (PAD-A) are terms that most accurately describe the process, taking into account who is prescribing or administering a lethal substance and the outcome of the actions. Literature that addresses this practice should be described as ending life literature. The standardized language needs to be used on death certificates so we can most accurately assess the impact that provider-assisted death is having on society. Emphasizing truth telling in morally controversial practices will foster trust among health care providers and with patients.

Exploring the Association Between Physical Activity and Cognitive Function Among People Living with Dementia.

Background: Physical activity preserves cognitive function in people without dementia, but the relationship between physical activity and cognitive domains among people living with dementia is unclear. Objective: The objective of this study was to explore the association between physical activity and cognition domains among people living with dementia. Methods: Participants living with dementia in residential care facilities (complete case analysis: n = 24/42) completed a battery of cognitive tests (global cognition: Montreal Cognitive Assessment; executive function: Trail-Making Test, Digit Span Forward Test; perception and orientation: Benton Judgement of Line Orientation Test; language: Boston Naming Test; learning and memory: Rey Auditory Verbal Learning Test; complex attention: Digit Symbol Substitution Test). Participants wore an actigraphy monitor on their non-dominant wrist over seven days. We conducted a linear regression for total physical activity (independent variable) with race (white/black), fall risk (Morse Fall Scale), and the number of comorbidities (Functional Comorbidities Index) as covariates, and cognitive tests as variables of interest. Results: Participants were primarily male (75%), white (87.5%), and 50%had unspecified dementia (Alzheimer's disease: 33%). Greater physical activity was associated with poorer global cognition, better executive function, and better learning and memory (ps <  0.05). Physical activity was not related to visuospatial perception, language, or complex attention. Conclusions: Physical activity may preserve executive function and learning and memory among people living with dementia. Wandering is more common in later stages of dementia, which may explain greater physical activity observed with lower global cognition. Regularly assessing physical activity may be useful in screening and monitoring cognitive changes.
