Lenka A, et al. – The physicians conducted this work to determine the changes in the resting state functional brain connectivity, whether any, in patients with primary writing tremor applying graph theory–based analysis. It was shown that patients with primary writing tremor have significantly altered small–world brain connectivity in bilateral medial cerebellum, right dorsolateral prefrontal cortex, and left posterior parietal cortex. Further studies with larger sample size are needed to verify the outcomes.
