Depression is a neuropsychiatric disorder that is expressed in emotional, physiological and behavioral effects. Depressive disorder is common, chronic and severely damages quality of life, often leading to risk due to suicidal tendencies. Over 12% of the American population suffers from depression over the course of their lifetime.
The brain reward system is the neuronal circuitry related to emotional phenomena such as hedonism and depression, and includes brain centers and pathways that are activated by natural and artificial rewards. The most important brain reward centers, such as the nucleus accumbens, the ventral tegmental area (VTA) and the ventral prefrontal cortex, are located at depths of 3-7 cm within the brain.
Transcranial magnetic stimulation, or TMS, uses a magnetic coil to stimulate these specific brain regions. With Brainsway’s Deep TMS therapy, an H-coil is used to stimulate deep in to the brain, with more accuracy in the structures it targets. This magnetic field briefly stimulates different brain regions associated with depression. This stimulation can cause impressive improvement for patients with treatment resistant depression.
