Latest research: Aging & dementia

What it found: A meta-analysis of 14 Parkinson’s studies and 10 Alzheimer’s studies found consistently greater variability in time estimates in both diseases, but impaired average accuracy only in Alzheimer’s disease.

Why it matters: When assessing timing skills in people with Parkinson’s or Alzheimer’s disease, practitioners should consider variability across responses rather than relying only on average accuracy.

What it found: In a longitudinal cohort of 85 adults with intellectual disability, carer-reported low physical endurance was associated with dementia six years later after adjustment for age and level of disability.

Why it matters: Staff observations of low physical endurance alongside other changes may help inform referrals for dementia assessment, although this finding needs confirmation in larger samples.

What it found: This pilot study found preliminary evidence that a virtual meal-preparation task was feasible for older adults and that community engagement studios helped generate strategies to improve intervention design and reach.

Why it matters: Virtual meal preparation may be worth exploring for older adults at increased risk of dementia, but this abstract does not establish improvements in cognitive or behavioral skills.

What it found: Across three cohorts totaling 1,396 dementia-free Chinese adults aged 50 or older, impulse dyscontrol was the most prevalent mild behavioral impairment domain, with irritability and agitation common in the Hangzhou cohort.

Why it matters: For staff supporting Chinese older adults, these findings highlight the importance of attending to irritability and agitation during assessment while considering cultural differences in behavioral presentation.

What it found: The study used network analysis and association rules to describe co-occurring health conditions by sex in Irish adults aged 50 and older with intellectual disability and compare patterns with the general population, but the abstract reports no specific findings.

Why it matters: Considering multiple co-occurring health conditions may help ABA staff coordinate with healthcare providers when planning supports for older adults with intellectual disability.

What it found: Among 353 dementia–caregiver pairs in Thailand, a 12-week exercise and behavioral program was followed by reduced caregiver burden, depression, and distress and improved dementia symptoms, daily functioning, and cognition.

Why it matters: Combining exercise with behavioral and psychosocial support may help community dementia services address both older adults’ functioning and family caregivers’ well-being.

What it found: Interviews with 30 family caregivers of older adults who died with dementia identified perceived personality changes, failure to recognize caregivers, wandering, physical shutdown, and sharply reduced self-sufficiency during the last weeks of life.

Why it matters: These caregiver observations can help staff anticipate changing support needs and discuss end-of-life changes with families, although the study did not test interventions.

What it found: Among 684 older adults reporting a positive COVID-19 test, those reporting Long COVID had higher self-reported cognitive and behavioral symptom scores associated with dementia risk than those without Long COVID.

Why it matters: For staff supporting older adults, these findings highlight the value of documenting new cognitive and behavioral changes and coordinating medical follow-up without assuming Long COVID causes dementia.

What it found: In 1,200 adults aged 70 or older, a 25-item self-care scale showed acceptable to high internal consistency across four daily-living domains and weak positive correlations with another self-care measure.

Why it matters: The scale may help structure assessments of older adults’ daily-living needs, although this study did not test its usefulness for selecting or evaluating ABA interventions.

What it found: In a randomized trial of 135 older adults, six-week behavioral activation and positive psychology programs produced similar improvements in life engagement that lasted three months, with positive psychology showing benefits on some outcomes for participants with more limited functional and cognitive resources.

Why it matters: When supporting older adults’ engagement and well-being, practitioners should consider functional and cognitive abilities rather than assume behavioral activation is more effective than a positive psychology approach.

What it found: An analysis of longitudinal data from 4,116 Korean adults over 45 found that lower expectations about the future were associated with greater odds of cognitive impairment and dementia, particularly expectations about national policies.

Why it matters: For staff supporting older adults, these findings highlight future-related concerns as potentially relevant context, but do not establish that changing expectations prevents cognitive decline.

What it found: Interviews with 17 adults aged 65 and older found that they valued online exercise classes but preferred in-person classes and intended to continue online mainly when barriers prevented in-person attendance.

Why it matters: When planning exercise supports for older adults, practitioners should consider individual preferences and offer online or hybrid options when attendance barriers arise.

What it found: In a pilot survey of 18 music therapists with follow-up interviews, 89% reported that the Music Therapy Assessment for Older Adults covered relevant treatment-planning domains, and 89% would continue using and recommending it.

Why it matters: For ABA staff working with older adults, this study highlights the value of reviewing assessment tools for treatment-planning relevance and inclusive language, but does not establish improved client outcomes.
