RTMS in the Elderly and After ECT
At the 2015 meeting of the Society of Biological Psychiatry in May, researcher Daniel Blumberger reported to this editor (Robert M. Post) that he has found repeated transcranial magnetic stimulation (rTMS) to be effective for depression in late life. Blumberger noted that it may be necessary to use higher intensity stimulation (i.e. at 120% of motor threshold instead of the usual 110% of motor threshold) in the elderly in order to overcome the gap between the skull and the brain, which can grow with age due to brain atrophy.
Blumberger has also successfully used rTMS as a followup treatment to a successful course of electroconvulsive therapy (ECT), administering rTMS twice a week for up to 66 treatments in a given patient in order to maintain remission of their depression.
