Abstract:The abnormalities in static brain activity in patients with post-stroke depression (PSD) have been widely reported. However, the dynamics of neural activity in PSD remain enigmatic. We investigated the abnormalities in dynamic neural activity in patients with PSD with the dynamic amplitude of low-frequency fluctuation (dALFF) method. Imaging and clinical data from 25 patients with PSD and 28 without PSD collected from April 2020 to June 2023 were evaluated. The between-group comparisons of dALFF variance and s… Show more
