How does rTMS work in Depression
Scientific research has shown that the cause of depression lies in the frontal cortex (the frontal lobe). In depression there is decreased activity in the left frontal cortex. To be more precise: in a small area in the brain named the Dorsolateral Prefrontal Cortex (DLPFC).
Using rTMS, this small area can be specifically stimulated. Depressive symptoms will decrease and this area will function better after repetitive magnetic stimulation of this area. This effect usually lasts for approximately 6-12 months.
This period of time is often enough to resolve the depressive symptomatology for a longer time, due to the cyclical nature of depression. If the depressive complaints do come back after this time, it is possible to get some refresh sessions tot preserve the antidepressive effect.
Usually there is a noticable effect within 10 session of rTMS treatment. Within this time frame it can therefore also be evaluated whether the treatment is efficacious or not. More than > 60% of the people respond positively to rTMS therapy and there are hardly any (or none) side effects to be expected with this treatment. In a recent report from the FDA it was stated that rTMS can be considered a safe treatment.
