PRESIDENTIAL SYMPOSIUM: CONCURRENT GAIT AND COGNITIVE IMPAIRMENT AS AN EMERGING GERIATRIC SYNDROME
Bibliographic record
Abstract
Gait and cognitive impairments are ubiquitous in older adults and often coexist in the same individual, even in the clinical absence of overt neurological conditions. Both conditions represent independent risk factors for dementia, falls and disability. However, until recently, clinicians and researchers have evaluated and treated cognitive and mobility dysfunction in older individuals as separate problems. This approach has led to gaps in our understanding of the motor-cognitive interactions and of the potential underlying mechanisms that can affect pathways to disability in aging. Emerging evidence indicates that gait is not a merely automated motor activity, but rather a task that requires executive function and attention as well as judgment of external and internal cues. Six recognized experts in the field from 3 different IAGG regions will participate in this symposium. First, we will examine clinical evidence from large-scale studies that demonstrate that individuals with cognitive and gait impairments in absence of overt neurological diseases may represent a phenotype with an increased risk of developing dementia, falls, and disability. Second, mechanistic evidence from brain structural and metabolic imaging studies and functional near infrared spectroscopy in healthy older adults and older adults with neurodegenerative diseases will be summarized. In conclusion, a roundtable debate will discuss whether there is sufficient evidence to support the idea that gait and cognitive impairments among older individuals in the absence of an overt neurological disease represent a distinct phenotype caused by shared mechanisms.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
