Transcranial Magnetic Stimulation (TMS) is a non-invasive treatment that uses magnetic fields to stimulate nerve cells in the brain, primarily employed for depression and other neurological conditions. As individuals consider this therapeutic option, a common question arises regarding its potential impact on energy levels, specifically if TMS can lead to feelings of tiredness or fatigue. Understanding how TMS affects the body is important for those undergoing or considering the treatment.
What is TMS and Its Typical Side Effects?
TMS involves placing an electromagnetic coil against the scalp, which generates focused magnetic pulses. These pulses create small electrical currents in targeted brain regions, modulating neural activity. Patients remain awake during sessions. TMS aims to stimulate nerve cells in areas of the brain that may have reduced activity, such as those involved in mood regulation.
While TMS is generally considered well-tolerated, some individuals may experience mild and temporary side effects. Common reactions include scalp discomfort or pain at the treatment site, and mild headaches. Some patients also report a tingling sensation or facial muscle twitching during the magnetic pulses. Fatigue or tiredness is another side effect that about one in three individuals may experience, particularly during the initial phase of treatment. These effects typically subside shortly after a session and tend to decrease as treatment progresses.
The Reasons Behind TMS-Related Tiredness
The feeling of tiredness after TMS sessions can be attributed to the brain actively working and adapting to the stimulation. The magnetic pulses cause neurons to fire more frequently than they typically would, which some describe as a “mental workout” for the brain. This increased neural activity requires the brain to expend more energy, similar to how physical exercise can lead to muscle fatigue. The brain uses glucose as its primary energy source, and heightened activity during TMS can deplete these energy reserves, contributing to feelings of drowsiness.
TMS also encourages the growth and strengthening of new neural connections and pathways. This process of neuroplasticity, where the brain reorganizes itself by forming new communication patterns, demands considerable energy, which can be perceived as mental exertion and subsequent fatigue. The intensity and frequency of TMS sessions can also influence the degree of tiredness experienced, with longer or more frequent sessions potentially leading to more noticeable fatigue. Specific brain regions targeted by TMS may also play a role in inducing feelings of tiredness.
Coping with Fatigue During TMS Treatment
For individuals experiencing fatigue during TMS treatment, several practical strategies can help manage this temporary effect. Ensuring adequate rest, maintaining a consistent sleep schedule, and aiming for sufficient hours of sleep each night are important. Staying well-hydrated, especially before and after sessions, can also support overall energy levels. Consuming a balanced diet, including complex carbohydrates and healthy fats, can be beneficial.
Incorporating light physical activity, such as a short walk, before or after sessions may help improve blood flow and reduce feelings of mental strain. Patients should communicate openly with their healthcare provider about any fatigue they experience. The treatment team can offer personalized advice, adjust session parameters if appropriate, and provide reassurance. Discussing persistent or severe tiredness with a doctor ensures proper management and support throughout the treatment course.
