Antidepressants are a systemic method of treatment for depression which focus on regulating chemical neurotransmitters that effect mood and emotions. A course of antidepressants can take several weeks to feel the effects and often carry with them serious side effects such as weight gain, nausea, emotional numbness, sexual dysfunction and insomnia.
Transcranial Magnetic Stimulation is a non-invasive treatment for depression which focuses on the regulation of neural activity in the brain. As rTMS is non-systemic, it has very few side effects and patients usually can see benefits within two and a half to three weeks of treatment.
TMS is usually considered if an individual is unresponsive to antidepressants or is unable to tolerate their side effects.
