Prefrontal Cortical Asymmetry and Motor Slowing in Older Women: EEG Evidence That Fear of Falling Modulates Emotional Valence and Reaction Time
Fear of falling triggers measurable brain changes and motor slowing in older women, identifying a neurophysiological mechanism to target for fall prevention.
This EEG study of 55 older women demonstrates that fear of falling substantially alters prefrontal cortical activation patterns and reaction time, with fear intensity (FES-I score) strongly correlated to cortical asymmetry and motor slowing. The findings suggest a neurophysiological mechanism for fall risk perpetuation and support the concept of fear of falling as a cortical biomarker, though the small cross-sectional study in a single-country sample limits generalizability.

Why it surfaced
Small EEG study in older women; relevant to aging/fall prevention but limited by N=55 and cross-sectional design; best candidate from aging topic this window
