The temporal variability of the dynamic functional connectivity (dFC) has been suggested as a useful metric for studying abnormal cognitive function. This study aimed to explore the associations between the temporal properties of dFC and memory performance in betel quid dependence (BQD). Sixty‐four BQD individuals and 47 gender‐ and age‐matched healthy controls (HCs) underwent functional magnetic resonance imaging and a series of neuropsychological assessments. The dFC was constructed by calculating the Pearson correlation coefficients within a sliding window and was clustered into three functional connectivity states using k‐means clustering. The dFC temporal properties derived from the cluster results were compared between the BQD and HC groups. The results showed that States 1 and 3 featured more frequent and weak connectivity, and State 2 featured less frequent and strong connectivity. There were significant differences for mean dwell time (MDT) in State 3 (p = 0.022) and fraction of time in State 2 (p = 0.018) between the BQD and HC groups. Pearson correlation analyses showed that the MDT in State 1 was negatively correlated with long delay free recall and short delay free recall, and the MDT in State 3 was positively correlated with false positive of long delay recall. Our findings provide strong evidence that MDT match the memory performance and suggest new insights into the pathophysiological mechanism of memory disorders in BQD individuals.

“…Finally, to our knowledge, there are no BQ studies on resistance to PI. Previous BQ studies on memory (e.g., Chiu et al, 2016;Lee et al, 2022) showed that BQ chewers may have de cits in some respective of memory such as spatial working memory (WM) (Chiu et al, 2016). It may be possible that chewers could have a worse resistance to PI, compared to controls.…”

Background: Betel-quid (BQ) is regarded as a human carcinogen by the World Health Organization. We asked whether BQ chewers have worse inhibitory control, in terms of three separate inhibitory control functions: propotent response inhibition, resistance to distractor interference, and resistance to proactive interference (PI). Methods: The antisaccade task, the flanler task and the recent-probe task are employed to measure the three inhibition functions, respectively. BQ dependent chewers with concurrent use of tobacco and alcohol (BQD), tobacco and alcohol user controls (TAC), and healthy controls (HC) were included. Results: We found that the BQD group did not differ from TAC and HC in prepotent response inhibition, measured by the antisaccade task, and resistance to distractor interference, measured by the flanker task. Finally, the BQD group had a worse resistance to PI than the two control groups, measured by the recent-probe task. Conclusions: When discussing from the perspective of multifacted inhibitory control, we can fully understand the inhibitory control ability of BQ chewers.
