dTMS vs rTMS
| Feature | Deep Transcranial Magnetic Stimulation (dTMS) | Repetitive Transcranial Magnetic Stimulation (rTMS) |
| Definition | dTMS is a non-invasive brain stimulation technique that uses an H-coil to target deeper brain structures. | rTMS is a non-invasive brain stimulation technique that uses a magnetic coil to target specific regions of the brain. |
| Depth of Stimulation | Penetrates deeper into the brain, targeting subcortical regions. | Primarily targets the cortical surface of the brain. |
| Targeted Areas | Effective in treating conditions like depression, OCD, and addiction, as it can reach deeper brain structures. | Often used for disorders like depression, anxiety, and some neurological conditions affecting the cortex. |
| Treatment Duration | Sessions typically last 20-30 minutes and are administered daily over several weeks. | Sessions generally last 30-60 minutes and are administered daily for several weeks. |
| Frequency of Sessions | Frequency may vary but often involves daily sessions. | Frequency of sessions may vary depending on the specific condition being treated. |
| Treatment Depth Control | Offers the advantage of adjusting the coil’s parameters to target specific deep brain structures. | Limited in its ability to specifically target deep brain regions, as it primarily affects the cortical surface. |
| Side Effects | Side effects are generally mild and temporary, including headache, scalp discomfort, and light-headedness. | Side effects may include headache, scalp discomfort, and, rarely, seizures. |
| Effectiveness | Effective in cases where targeting deeper brain regions is crucial for symptom relief. | Highly effective for treating conditions primarily involving the cortical surface of the brain. |
| Conditions Treated | Particularly beneficial for treatment-resistant depression, OCD, and addiction disorders. | Widely used for depression, anxiety disorders, and certain neurological conditions like migraines and epilepsy. |
| FDA Approval | FDA-approved for treating depression and OCD. | FDA-approved for treating depression, migraines, and some other neurological conditions. |
| Accessibility | Availability may be limited in some regions due to specialized equipment and expertise required. | More widely available in many psychiatric and neurological treatment centers. |
| Cost | Can be relatively costly due to the specialized equipment and training required for its administration. | Generally more accessible and cost-effective compared to dTMS. |
It’s important to note that the choice between dTMS and rTMS depends on the specific condition being treated, the depth of stimulation required, and the expertise and equipment available at the treatment facility. Consulting with a psychiatrist or medical professional is crucial in determining the most appropriate treatment approach for each individual.
