What is transcranial magnetic stimulation (TMS)?

Transcranial magnetic stimulation (TMS) is a non-invasive treatment that involves using an attractive coil to influence your brain’s natural electrical activity. This treatment, first developed in 1985, now sees widespread use for a variety of mental health and brain-related conditions.


Why would a magnet affect how my brain works?

Transcranial magnetic stimulation relies on two basic principles of physics: electricity and magnetism. These two principles can also work cooperatively, and TMS relies on their ability to work together.

The space surrounding a magnet is magnetically active, and a magnet’s influence in that space is known as the magnetic field. You can’t see it, but that space still shows the effects of the magnet at its center. When you bring a magnet near something that conducts electricity, the interaction between the conductive item and the magnetic field generates electricity. Read more

RAPID ANTIDEPRESSANT EFFECTS OF REPEATED DOSES OF KETAMINE COMPARED WITH ELECTROCONVULSIVE THERAPY IN HOSPITALIZED PATIENTS WITH MAJOR DEPRESSIVE DISORDER

  Abstract Accumulating evidence suggests that N-methyl-d-aspartate receptor (NMDAR) antagonists (e.g. ketamine) may exert rapid antidepressant effects in MDD patients. In the present study, we evaluated the rapid antidepressant effects of ketamine compared with the electroconvulsive therapy (ECT) in hospitalized patients with MDD. In this blind, randomized study, 18 patients with DSM-IV MDD were divided into two groups which received either three intravenous infusions of ketamine hydrochloride (0.5 mg/kg over 45 min) or ECT on 3 test days (every 48 h). The primary outcome measure was the Beck  Depression  Inventory (BDI) and Hamilton Depression Rating Scale (HDRS), which was used to rate overall depressive symptoms at baseline, 24 h after each treatment, 72 h and one week after the last (third) ketamine or ECT. Within 24 h, depressive symptoms significantly improved in subjects receiving the first dose of ketamine compared with ECT group. Compared to baseline level, this...

4 REASONS TO USE KETAMINE INSTEAD OF ANTIDEPRESSANTS

Image
If you're looking for something new to try, ketamine could be your answer! Ketamine is an FDA-approved drug that is more effective than antidepressants in people who are depressed. It works by blocking the brain's NMDA receptors, which increases serotonin levels and can also help with mood swings. Ketamine might sound like a scary drug, but it's one of the safest drugs available for depression because its effects wear off after about 3 days (compared to antidepressants where withdrawal symptoms last weeks). Four reasons why you should use ketamine instead of antidepressants: A different class of drugs  - Ketamine is classified as a dissociative anesthetic. In that role, it has been safely used in children, adults, and animals for decades. However, ketamine produces different results depending on the dose. More effective than antidepressants  -  10-30% of patients  fail to respond to their antidepressant medication. Even after trying several different types of antidep...
