Artificial Intelligence

Background:

Dual-task paradigms integrate cognitive and motor functions, offering insights into subtle age-related impairments.
Early detection of cognitive and physical decline in older adults is crucial for timely intervention.

Purpose of the Study:

To employ artificial neural network (ANN) modeling for predicting clinical, cognitive, and psychosocial outcomes.
To identify key predictors of cognitive and psychosocial status from integrated dual-task data.

Main Methods:

Collected gait, speech-linguistic, demographic, physiological, and psychological data during single- and dual-task conditions.
Utilized hyperparameter tuning and k-fold cross-validation for ANN model optimization.
Predicted outcomes including Montreal Cognitive Assessment (MOCA), Trail Making Tests (TMT A and B), and Activities-Specific Balance Confidence (ABC) Scale.

Main Results:

ANN models achieved high accuracy in predicting MOCA (100%), ABC Scale (80%), memory function (80%), and social support satisfaction (75%).
Speech-linguistic markers and sensory impairments were identified as significant predictors.
Specific linguistic features, like pronoun usage, strongly predicted cognitive measures.

Conclusions:

ANN models demonstrate significant potential for the early detection of cognitive and psychosocial changes.
Integrated dual-task data provides a rich source for predictive modeling in aging research.
