Clinical Trial Summary

The purpose of the current open-lable study was to use low-frequency repetitive transcranial magnetic stimulation (rTMS) to improve the attention deficits in a sample of adult patients suffering from attention deficit disorder. Participants received 10 sessions of rTMS over Fz (located using the EEG 10-20 international system) and underwent assessments of their attentional capacity using the gradCPT task in an fMRI scanner, before and after the intervention. Other behavioral assessments of their attention symptoms have also been conducted.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in performance	Shortened version (4 min) of the continuous go/no-go task: gradual-onset continuous performance task (gradCPT)	Up to 10 days, i.e., before and after the completion of the 10 sessions of rTMS
Secondary	Change in self-report attention scores	The 6-item ASRS-V1.1 Adult ADHD Self-Report	Baseline, after 5 days of stimulation, after 10 days of stimulation; Range= 0-6; Higher scores represent worse outcome
Secondary	Change in investigator-rated attention scores	Investigator-Rated Attention-Deficit Hyperactivity Disorder (ADHD) Rating Scale-IV (I-ADHD RS-IV) with adult prompts	Baseline, after 5 days of stimulation, after 10 days of stimulation; Range:0 - 54; Higher scores represent worse outcome
