TMS for Schizophrenia: Exploring the Potential Benefits of TMS Therapy

If you or someone you know is living with schizophrenia, finding the right treatment can be an ongoing challenge. While medications are often the first line of defense, they don’t always provide complete relief from symptoms. This is where alternative treatments like Transcranial Magnetic Stimulation (TMS) for schizophrenia come into the picture. TMS is currently being explored as a potential option to help address symptoms that traditional treatments may not fully resolve.

An Overview of TMS and Schizophrenia

TMS is a potential option for managing symptoms of schizophrenia, especially for those who haven’t responded to traditional treatments. As schizophrenia affects how a person perceives reality, TMS is a non-invasive treatment that targets specific areas of the brain. 

What is Transcranial Magnetic Stimulation?

TMS is a non-invasive procedure that uses magnetic pulses to stimulate nerve cells in the brain. The process involves repetitive pulses, which is why it’s often referred to as repetitive TMS (rTMS). During each session, hundreds or thousands of these magnetic pulses are delivered to targeted areas of the brain. The goal is to regulate abnormal brain activity that may be contributing to symptoms. 

Schizophrenia and its Symptoms

Schizophrenia is a serious mental health condition that affects how individuals perceive and engage with the world around them. It can lead to a breakdown in the connections between thoughts, emotions, and behaviors which can make everyday life challenging. While the severity and combination of symptoms can differ from person to person, the most common symptoms are: 

  • Hallucinations, such as hearing voices or seeing things that aren’t there
  • Delusions, involving strongly held false beliefs not based in reality
  • Reduced expression of emotions, often referred to as “flat affect”
  • Lack of motivation to pursue everyday tasks or goals
  • Cognitive impairments, like trouble concentrating or remembering things
  • Social withdrawal, avoiding interactions and relationships with others
  • Motor disturbances, including unusual movements or lack of coordination

Can TMS Work for Schizophrenia? 

TMS is gaining attention as a potential treatment for schizophrenia, especially for those who have not experienced sufficient relief with conventional therapies. While it is not yet FDA-approved for schizophrenia, studies suggest TMS may provide benefits by directly targeting abnormal brain activity associated with the condition. 

How TMS Targets the Brain in Schizophrenia

Research indicates that individuals diagnosed with schizophrenia exhibit distinct brain activity patterns in regions like the temporoparietal cortex (TPC) and the dorsolateral prefrontal cortex (DLPFC). Abnormal activity in these areas contributes to symptoms like auditory hallucinations and decreased motivation. TMS aims to modulate these patterns to help manage symptoms through low-frequency TMS or high-frequency TMS: 

  • Low-frequency TMS (1 Hz) is applied to the left TPC to reduce heightened activity linked to auditory hallucinations. 
  • High-frequency TMS targets the left DLPFC to stimulate brain activity, which may improve negative symptoms like social withdrawal. 

Comparing TMS with Traditional Schizophrenia Treatments

While antipsychotic medications are the primary treatment for schizophrenia, they mainly only address positive symptoms like hallucinations. Unfortunately, negative symptoms and cognitive impairments typically remain unresponsive to these drugs. TMS differs by focusing on altering brain activity patterns, potentially addressing symptoms that traditional medications may not alleviate.

How Effective is TMS for Schizophrenia Symptoms? 

TMS shows promise in targeting certain symptoms of schizophrenia; however, its effectiveness can depend on the type of symptoms and individual patient characteristics. Research suggests that TMS may help reduce positive symptoms and could also alleviate some negative symptoms, though results are mixed. 

TMS and Positive Symptoms

Positive symptoms of schizophrenia are those that add abnormal experiences, such as hallucinations, delusions, disorganized speech, and unusual behaviors. TMS, when applied to the left temporoparietal cortex, has shown potential in reducing the intensity of these symptoms. For instance: 

However, the effectiveness of TMS for positive symptoms is not consistent across all studies. Some trials involving patients with severe or treatment-resistant forms of schizophrenia did not find significant differences between TMS and sham treatments. Factors like small study sizes, varying TMS protocols, and medication use may contribute to these mixed results. 

TMS and Negative Symptoms

Negative symptoms refer to the absence or reduction of normal functions like emotional expressions, motivation, and social engagement. High-frequency TMS targeting the left dorsolateral prefrontal cortex has show some promise alleviate these symptoms: 

  • Improvements in social withdrawal and motivation were observed in five out of ten controlled studies. 
  • Some participants experienced a significant reduction in negative symptoms after two weeks of daily TMS. 
  • Other trials saw additional benefits for depressive symptoms alongside negative symptoms. 

Despite these findings, not all studies have reported success. Some research failed to demonstrate substantial improvement, possible due to factors like the treatment duration, lower TMS doses, or differences in patient conditions. 

What to Know Before Trying TMS for Schizophrenia

While some studies have shown positive results in using TMS to treat symptoms of schizophrenia, its overall effectiveness remains uncertain and widely debated. Variability in study methods makes it difficult to draw definitive conclusions about its benefits. Because TMS is not yet approved by the FDA for schizophrenia, any use of this treatment for the condition is considered “off-label,” and the procedures may vary depending on the clinic and doctor. 

If you’re considering TMS for schizophrenia, here are some important things to keep in mind: 

  • TMS is performed in a doctor’s office. Each session lasts about 30 to 40 minutes, and the treatment usually spans 4 to 6 weeks with daily sessions on weekdays. 
  • You’ll need to remove any metal objects like jewelry or magnetic accessories before the session. Earplugs should be worn to protect against the loud clicking sounds from the TMS machine. 
  • You may feel a tapping sensation on your scalp, but the procedure is generally painless and doesn’t require anesthesia. 
  • TMS is considered a well-tolerated treatment, but some people may experience mild and temporary side effects like headaches, scalp discomfort, or facial muscle twitching. 
  • Since TMS for schizophrenia is not standardized, different doctors may use varying levels of stimulation and target different areas of the brain. As such, results can differ from person to person. 

It’s important to discuss with your healthcare provider whether trying TMS off-label is the right choice for you. Ask about the potential risks, benefits, and alternative treatment options to make an informed decision.
