Muscle loss as modifiable target in dementia care
The review describes age-related changes in muscle and cognitive function and links sarcopenia, frailty and cognitive impairment as interconnected geriatric syndromes. It states that skeletal muscle loss is the central pathophysiological substrate across these syndromes but is still insufficiently prioritized as a treatment objective. The authors argue that incorporating the malnutrition-sarcopenia-frailty triad into dementia care is essential for continuity of management, because muscle preservation is described as fundamental to sustaining cognitive function within an active aging paradigm.

Proposed supplement strategy and limited cognitive evidence
The review explores muscle-brain crosstalk and highlights skeletal muscle loss as a modifiable target for nutritional intervention in cognitive impairment and dementia. Given bidirectional links between malnutrition, sarcopenia, frailty and cognitive decline through shared aging mechanisms, the authors conclude that a high-protein oral nutritional supplement enriched with beta-hydroxy-beta-methylbutyrate (HMB) and vitamin D emerges as a practical, compliant strategy to support muscle health. They add that it could potentially contribute to preserving cognitive health in older adults with or at risk of dementia, although direct evidence for cognitive benefit remains limited.

Narrative review scope: no new trial data reported
This is a narrative review prepared by experts in neurology and geriatrics, not a new clinical trial. The abstract reports no sample size, follow-up period or measured cognitive outcome. The supplement is presented as a proposed practical strategy, and the authors themselves state that direct evidence for cognitive benefit remains limited. The abstract therefore does not establish that the supplement preserves cognition or prevents dementia; the full text was not reviewed.
