Side Effects of rTMS: What You Should Know
Headache, local sensitivity, fatigue, and other possible reactions during an rTMS treatment.
Every treatment decision requires a clear conversation about benefits, discomforts, and risks. With repetitive transcranial magnetic stimulation (rTMS), the experience is usually outpatient, but that doesn't mean everyone feels exactly the same way.
Scalp Discomfort
The coil delivers pulses near the head. Some people notice tapping, pressure, tingling, or sensitivity at the application site. These sensations may be more noticeable during the first sessions.
If the discomfort is significant, it should be reported. The team can check the positioning, explain what is expected, and make any adjustments the protocol allows.
Headache
Headache is one of the most commonly reported reactions. It can occur during or after the session and is usually described as temporary.
A history of migraines or other conditions should be reported before starting. The clinician can indicate how to track and manage any episode.
Fatigue
Some people feel tired after stimulation. This can be especially relevant in accelerated protocols, which include several applications on the same day.
Planning breaks, meals, and rest can help you get through intensive days, always following the center's guidance.
Noise and Hearing Protection
The coil produces a repetitive sound. For this reason, hearing protection is part of the preparation. People with hearing problems should mention this so they can receive a proper evaluation.
Twitches or Local Movements
The stimulus can activate nearby muscles and cause brief sensations or movements in the face or scalp. The team monitors position and intensity to keep the application within the set parameters.
Rare Risks
Rare events exist that call for safety protocols, seizures among them. Evaluating history, medications, and risk factors reduces the likelihood and helps in selecting the right treatment.
Noticeable changes in mood or behavior should also be monitored. Any unexpected change deserves to be reported.
What to Ask Before Starting
A useful conversation may include:
- What are the most common discomforts with this protocol?
- What should I report during a session?
- What symptoms require immediate medical attention?
- How is the intensity adjusted if I feel pain?
- Who do I contact outside of regular hours?
Keeping Track of Your Experience
Writing down what happens after each day helps identify patterns. Time, intensity, duration, and any measures taken provide useful information for follow-up.
Knowing the possible effects allows for an informed decision and helps avoid two extremes: assuming every discomfort is serious, or believing no reaction can occur at all.
