the antidepressant effects of rtms after ischemic stroke

Conditions: Post-stroke Depression

Summary: this is a multicenter, randomized, double-blind, placebo-controlled trial aims to assess the effectiveness of repetitive transcranial magnetic stimulation(rtms) in treating depression after basal ganglia ischemic stroke and to examine whether such effects are related to restoration of white matter integrity.sixty-six participants will be recruited from three centers and randomized with a 1:1 ratio to receive active rtms treatment or sham rtms treatment in addition to routine supportive treatments.the data of neuropsychological tests and mri will be collected at 0, 2 and 4 weeks after the commencement of the treatment.
