Basal ganglia calcifications (present in 31% of 253 older adults) were not significantly associated with impaired balance, gait, overall mobility, functional mobility, or recurrent falls.

Does the presence of basal ganglia calcifications associate with impaired mobility and recurrent falls in older adults?
Incidentally detected basal ganglia calcifications on brain CT scans are not associated with impaired mobility or recurrent falls in older adults.
Background: Basal ganglia calcifications (BGCs) are frequently detected on brain CT scans in older adults, but their clinical relevance for mobility and fall risk is unclear. This study investigated the association of BGCs with impaired mobility and recurrent falls. Methods: In this cross-sectional study, all consecutive patients referred to the mobility clinic of a regional teaching hospital between 2019 and 2021 were included. Mobility was assessed using the Performance-Oriented Mobility Assessment (POMA) for balance, gait and overall mobility, and the Timed Up and Go (TUG) test for functional mobility. All assessments were performed by a trained physiotherapist. Recurrent falls were defined as self-reported occurrence of more than one fall in the past 12 months. Brain CT scans were evaluated for BGCs by a trained senior radiologist and were scored by severity. Univariable and multivariable logistic regression analyses were performed, adjusting for age, sex, and history of cardiovascular events. Results: A total of 253 participants were included (median age 82 years; 58% female), of whom 31% had BGCs. Falls data were available for 246 participants, and 70% reported recurrent falls. In both univariable and multivariable analyses, there was no evidence of a statistically significant association between the presence of BGCs and impaired balance, gait, overall mobility, functional mobility, or recurrent falls. Conclusions: No evidence of a statistically significant association was found between incidentally detected BGCs and impaired mobility or recurrent falls in older adults. Further longitudinal research is needed to confirm these findings and clarify whether BGCs are clinically relevant for mobility and fall risk assessment.
Graaf et al. (Thu,) conducted a cross-sectional in Impaired mobility and recurrent falls (n=253). Basal ganglia calcifications vs. Absence of basal ganglia calcifications was evaluated on Impaired mobility (balance, gait, overall, functional) and recurrent falls. Basal ganglia calcifications (present in 31% of 253 older adults) were not significantly associated with impaired balance, gait, overall mobility, functional mobility, or recurrent falls.
