tDCS and transcranial magnetic stimulation (TMS) share some similarities. Both treatments modify neural activity in specific targets in the brain to help alleviate symptoms of a variety of neuropsychiatric disorders. However, there are several key differences. While TMS has been thoroughly investigated and FDA-approved for both depression and OCD, tDCS is still an experimental treatment that is currently still being researched for its therapeutic potential. In addition, while TMS requires physically visiting a clinic to receive the treatment, tDCS is portable and can be administered in the comfort of your home.
