What Does an rTMS Session Feel Like, During and After?
Sounds, local sensations, duration, and returning to your day: an explanation of what an rTMS session feels like.
Technical explanations describe how repetitive transcranial magnetic stimulation (rTMS) works, but many people want an answer to a more immediate question: what am I going to feel?
Before the Stimulation
The person sits in a chair, and the team positions the head. During the first session, motor threshold measurement and localization of the area to be stimulated may be performed.
The coil is placed on or very close to the scalp. The patient stays awake and can talk with the clinician.
The Sound of the Coil
When the stimulation begins, the coil produces a rhythmic sound. It can be heard as a rapid series of clicks followed by a pause. This pattern repeats throughout the session.
For this reason, earplugs or hearing protection are used. The team explains how to put them on and what level of noise to expect.
Sensations on the Scalp
Some people notice tapping, pressure, or tingling in the treatment area. The intensity may feel more noticeable at first and become more familiar as the session progresses.
If a sensation feels uncomfortable, it should be reported. The team can check the positioning and review the parameters within what the protocol allows.
During the Session
The person remains seated. Depending on the center, they may watch a screen, listen to an explanation, or simply rest. Duration varies depending on the type of stimulation.
Accelerated protocols include several sessions on the same day. Between them, there are intervals for walking, drinking water, eating, or resting, according to the instructions given.
After the Session
rTMS is usually administered on an outpatient basis. Once the session ends, many people go on with their normal activities. The center should explain whether there is any specific instruction for the protocol being used.
Possible discomforts include headache, scalp sensitivity, or transient fatigue. Frequency and intensity can vary. Any significant or unexpected reaction should be reported.
Can You Feel Improvement During the Session?
The therapeutic goal is assessed across the full course of sessions and follow-up. Some people describe early changes; others need more time. Another patient's experience does not necessarily predict an individual's response.
For this reason, care teams typically use rating scales and clinical conversations to track changes in mood, energy, sleep, concentration, and day-to-day functioning.
Coming In With a Realistic Picture
Knowing what sounds, sensations, and timing are part of a session reduces uncertainty. It also helps distinguish the expected experience from anything that should be reported to the clinician.
In "New Hope for Treatment-Resistant Depression Without Medication," the authors describe the session from a practical standpoint and answer patients' most frequent questions.
