Summary
Repetitive transcranial magnetic stimulation (rTMS) may induce seizures in patients with depression. This case highlights potential risks when using rTMS with certain medications, emphasizing seizure monitoring during treatment.
Area of Science:
- Neuroscience
- Psychiatry
- Neurology
Background:
- Repetitive transcranial magnetic stimulation (rTMS) is explored for its mood-enhancing effects in depression.
- Seizure induction is a primary safety concern associated with rTMS therapy.
Observation:
- A patient with drug-resistant depression experienced a complex partial seizure during high-frequency rTMS over the left dorsolateral prefrontal cortex (DLPC).
- The seizure was self-limiting with no reported physical sequelae.
Findings:
- The combination of prolonged rTMS train duration and norepinephrine-modulating drugs may have precipitated the seizure.
- The seizure's neuroanatomical localization appeared to be the DLPC.
Implications:
- This case underscores the importance of careful patient selection and monitoring for seizure risk during rTMS treatment.
- Further research is needed to understand the interplay between rTMS parameters, concurrent medications, and seizure induction in psychiatric patients.
