What to Expect During TMS Treatment

TMS treatment is a non-invasive procedure designed to stimulate specific brain areas linked to mood regulation, notably the prefrontal cortex. This uses magnetic pulses to reactivate underperforming brain regions, alleviating symptoms of depression and other mental health conditions. 

Around 50-60% of individuals with medication-resistant depression experience significant improvement with TMS, with approximately one-third achieving full remission of symptoms. Here’s a breakdown of what patients can expect during TMS treatment:

  • Initial Consultation and Preparation: Before starting TMS treatment, patients undergo an initial consultation to evaluate their suitability for the therapy. This assessment includes discussing medical history, current symptoms, and setting treatment goals with the healthcare provider to ensure the best outcome.
  • Personalized Mapping of Treatment Area: During the first session, a technician maps out the exact area of the brain to be stimulated. Using specialized equipment, they locate and mark the prefrontal cortex region. This ensures that the magnetic pulses are precisely targeted to maximize treatment effectiveness.
  • Positioning and Comfort Adjustments: Patients are seated in a comfortable chair, and adjustments are made to ensure the best possible positioning of the TMS machine. This includes the technician positioning the magnetic coil near the scalp to target the designated area accurately.
  • Short Sessions and Breaks: Each TMS session lasts approximately 20 to 40 minutes, depending on the individual’s treatment plan. Sessions are generally scheduled five times per week over several weeks. Patients have the opportunity to rest or take brief breaks if needed, especially during the initial sessions.
  • Gradual Improvement Over Time: TMS treatment is a cumulative process, with benefits gradually appearing over the course of multiple sessions. Most individuals start noticing improvements in mood and mental clarity after several weeks, with some experiencing increased energy and motivation.
  • Monitoring and Check-ins: Throughout the treatment period, patients regularly check in with their healthcare provider to monitor progress and discuss any side effects. These sessions provide an opportunity to adjust the treatment plan if necessary and to ensure that the patient is achieving the best possible outcome.

7 Effects of TMS Treatment and What to Anticipate for a Positive Experience

Reflecting its growing adoption, the global TMS system market is projected to expand at a compound annual growth rate (CAGR) of 9.0% from 2023 to 2030. But while TMS treatment is effective in alleviating symptoms of depression and other mental health conditions, it can also bring about some unexpected side effects. Fortunately, most of these effects are manageable and don’t pose any serious health risks to individuals on TMS. 

1. Changes in Sleep Patterns

One lesser-known effect of TMS treatment is its influence on sleep. Patients often report changes in their sleep patterns, which can vary widely:

  • Improved Sleep Quality: Some individuals find that TMS treatment helps them achieve deeper, more restful sleep. As mood improves, symptoms like insomnia or restless sleep may lessen, resulting in better-quality rest.
  • Disrupted Sleep Cycles: Conversely, some patients notice disruptions in their sleep patterns. Increased energy levels after sessions can make it difficult to wind down, leading to delayed sleep onset.

The changes in sleep are believed to be tied to how TMS treatment affects brain areas responsible for regulating circadian rhythms. As brain activity adjusts, the body’s internal clock may also shift. To manage these sleep changes, individuals can:

  • Stick to a Consistent Routine: Following a regular sleep schedule can help the brain and body adjust more quickly.
  • Avoid Stimulants: Reducing caffeine intake, especially in the afternoon, can minimize sleep disruptions.
  • Practice Relaxation Techniques: Activities like deep breathing and mindfulness exercises before bed can help ease the transition to sleep.

A healthcare provider can provide personalized tips for managing sleep changes, ensuring TMS treatment remains a positive experience.

2. Unexpected Emotional Responses

While TMS treatment is known for improving mood, it may also prompt surprising emotional shifts, some of which are unexpected:

  • Sudden Calmness or Contentment: Patients sometimes feel an overwhelming sense of calm or contentment during or after treatment. This positive shift might come as a surprise, especially for those who have long struggled with mood disorders.
  • Emotional Waves: Some individuals may experience spontaneous emotional waves, like brief moments of sadness or elation, that are unrelated to current thoughts or surroundings.

These emotional shifts are likely due to the brain’s ongoing adjustment to TMS treatment. As magnetic pulses stimulate areas related to mood, different emotions may emerge as the brain begins to regulate more effectively. These shifts are generally temporary and become less frequent over time. To navigate these changes, patients can:

  • Acknowledge and Accept: Recognizing that these emotions are normal can make them easier to handle.
  • Journal Emotions: Documenting feelings can help identify any patterns and allow for better communication with healthcare providers.

A healthcare provider can reassure patients about these changes and offer coping strategies tailored to their emotional experience.

3. Enhanced Sensitivity to Sound

An unexpected side effect of TMS treatment for some patients is an increased sensitivity to sound:

  • Sharpness of Everyday Sounds: Individuals might notice that regular sounds, such as typing or traffic, feel more intense.
  • Sensitivity to Loud Environments: Busy or noisy settings may feel overstimulating, leading to temporary discomfort or mild irritation.

This heightened auditory sensitivity may occur because TMS treatment affects the brain’s sensory processing centers, which amplifies responses to auditory input. While the effect is typically mild and short-lived, it can be surprising. Patients experiencing this heightened sensitivity can try:

  • Using Ear Protection: Earplugs or noise-canceling headphones can help reduce sound intensity during sensitive periods.
  • Practicing Deep Breathing: Taking a few deep breaths in noisy settings can help lessen overstimulation.

Discussing these experiences with a healthcare provider can clarify if adjustments to treatment might lessen sound sensitivity.

4. Altered Taste Perception

Patient

A rare but surprising effect of TMS treatment is a temporary change in taste perception. Although not widely reported, some individuals notice slight alterations in how they perceive flavors:

  • Enhanced Taste: Certain flavors may seem stronger, with foods tasting more intense or vibrant than usual.
  • Muted Flavors: Conversely, some individuals may experience a reduction in taste sensitivity, with foods tasting less pronounced.

This change in taste perception is likely due to how TMS treatment impacts sensory processing areas of the brain. If these taste changes persist, discussing them with a healthcare provider can help. Meanwhile, individuals can manage this by:

  • Experimenting with Mild Flavors: Choosing foods with subtle flavors may make meals more enjoyable.
  • Keeping Hydrated: Proper hydration can also improve sensory sensitivity and may help mitigate taste changes.

With time, most patients find that their sense of taste returns to normal as they adjust to TMS treatment.

5. Unusual Sensations During Treatment

As the magnetic coil is placed close to the scalp during TMS treatment, some patients report experiencing unique physical sensations:

  • Tingling or Tapping: Many describe feeling a mild tapping or tingling on the scalp as the magnetic pulses are delivered.
  • Warm Sensation: Some individuals may notice a slight warmth on their scalp, which can be unexpected but is generally harmless.

These sensations occur because the magnetic pulses stimulate nerves and muscles around the treatment area, which may feel unusual initially. Tips for managing these sensations include:

  • Ask for Adjustments: The TMS technician can make minor adjustments to increase comfort.
  • Practice Relaxation: Focusing on breathing can help patients relax during sessions, making these sensations easier to tolerate.

Understanding these sensations as normal responses to TMS treatment can help individuals feel more at ease. It’s also crucial to be vocal about comfort levels to ensure the best experience possible. 

6. Increased Energy Levels Post-Treatment

For many, one of the pleasant side effects of TMS treatment is an increase in energy levels. Patients frequently report feeling more alert and motivated following sessions, which enables them to enhance various aspects of their lives:

  • Improved Productivity: Individuals may find it easier to complete tasks and feel more motivated throughout the day.
  • Enhanced Physical Activity: With more energy, patients might be inclined to engage in physical activities, which can further boost mood and overall well-being.

This increase in energy is likely a result of the treatment’s positive impact on mood and brain stimulation. To make the most of this energy boost, individuals can:

  • Set Productive Goals: Channeling newfound energy into specific goals can improve productivity and focus.
  • Engage in Physical Exercise: Physical activity can help balance energy levels and promote better sleep.

If energy levels become too high and interfere with daily routines, healthcare providers can suggest ways to moderate this effect.

7. Depression Remission as an Unexpected Outcome

Although TMS treatment is commonly known to reduce depression symptoms, some patients are pleasantly surprised by full remission:

  • Complete Symptom Relief: For a subset of individuals, TMS treatment leads to a significant reduction in symptoms. This leaves them feeling mentally balanced and positive, which can be a surprising experience. 
  • Unexpectedly Rapid Results: Some patients notice that their symptoms improve faster than anticipated. This fast result can be overwhelming for some individuals who have been struggling for a long time. 

This outcome underscores the effectiveness of TMS treatment for certain individuals. However, results vary, with some patients experiencing gradual improvement and others finding complete symptom relief. Communicating these changes to a provider can help set realistic expectations and keep treatment aligned with personal goals.

When to Talk to a Healthcare Provider About Side Effects

Understanding when to reach out to a healthcare provider about side effects of TMS treatment can be essential for a safe and positive experience. While some effects are mild and temporary, others may require professional guidance. Providers can offer reassurance, coping strategies, and treatment adjustments if needed.
