Transcranial magnetic stimulation (TMS therapy), is an innovative treatment for severe depression. This involves using electrical charges to stimulate specific parts of the brain in order to restore nerve cells or alter the function of dormant nervous systems. This new method of treating mental depression is safer than Electroconvulsive therapy. This therapy is used to treat severe depression symptoms that have not responded well to other treatments. The therapy can also be used for other neurological and psychiatric conditions, such as strokes, migraines and depression symptoms. This is a more effective treatment.
To fully appreciate the benefits of Transcranial Magnetic Stimulation, we need to understand what it is. The brain can be treated with this non-invasive treatment to hyperpolarize or depolarize its neurons. This method uses electromagnetic induction to generate weak electric currents by using an alternating magnet field. This method produces activity in certain brain areas. Medical therapists can then examine the inter-connectivity and function between the cortex and muscle cortex. It is very comfortable and can be used to treat many neurological and psychiatric disorders. It can be used to treat strokes, Parkinson's disease, and depression.
Historical Background
In the 20th century, brain stimulation using eddy currents was first observed. Anthony Barker, an English researcher conducted the first successful TMS research. It was completed in 1985. The first application that demonstrated nerve impulses could be transmitted from the motor cortex into the spinal cord was published in 1985. This stimulated muscle contractions. An electrical current and magnets were used to reduce discomfort.
Uses of the TMS
There are two types: The diagnostic and the Therapeutic.
Therapeutic use
According to research and reports, TMS therapy is effective in treating certain types of major depression. These devices are available in the United States, Canada, Israel, and New Zealand. They can also be used to treat depression disorders in Australia, New Zealand and Canada.
TMS therapy is a method of measuring the activity and functionality in certain brain circuits in humans. This device measures the transmission between the primary motor cortex of a specific muscle and the primary motor cortex. This device could also be used to assess damage from strokes, multiple sclerosis, and spinal cord injuries.
What is TMS?
TMS creates electromagnetic fields that stimulate brain and mimic the effects of antidepressants. The electromagnetic fields act to inhibit serotonin-reuptake, increasing brain levels of extracellular serotonin.
Magnetic pulses are sent through skull via the FDA-approved machine, which is attached to the brain. An electrical current stimulates the tissues. It is usually done in a limited area and does not require the administration of any sedative. The medical therapist would determine the threshold level. Sessions last about forty minutes.
This treatment is effective for patients who are suffering from severe side effects of antidepressant medication. TMS is considered the most safest treatment, considering all possible outcomes. Research shows that TMS patients are less likely to develop depression again.
