Background- Cerebral ageing is a complex and heterogeneous process. Magnetic resonance imaging (MRI) is used to identify and quantify non-disease-related ageing of the cerebral white matter. Increased white matter hyper-intensities (WMHs), cerebral atrophy, reduced micro-structural integrity are common findings among older adults and have been associated with cognitive and gait impairment. This study examined the impact of multimodal white matter imaging on mobility and cognitive functions among community dwelling adults aged 50 years and above. Methods: 36 participants (50 to 75 years) without any prior history of neurological or orthopaedic disorder were included. Neuroimaging measures included volumetry ; WMH; FA & MD; Mobility was evaluated using walkway system with 30 comprehensive spatio-temporal parameters of gait (pace, rhythm, variability etc); Cognitive measures included color tail test A & B for executive functions and MMSE. Depression was also evaluated using the Geriatric depression scale. Results- The mean age was 62 (±2.34) years, 44% were male. WMHs were found in 19 out of 36 participants. WMHs were found to be significantly associated with gait velocity (P value =0.009), stride length (P value =0.025), double stance time (P value =0.036). Reduced gait velocity was associated with reduced FA and higher MD. Most of the brain measure association was found with pace and phase gait parameters. Conclusions: The data suggests that in non-clinical ageing populations, mobility measures may be sensitive to subtle brain MRI measures. Identifying these early changes of structural and functional correlates will have a major impact on future clinical and public health priorities
