What causes depression?

While the exact cause of depression is not known, the leading scientific theory is that it is caused by an imbalance of the brain’s neurotransmitters, which are chemical messengers that send signals between brain cells.

While antidepressant drugs work for many people, some still do not receive adequate treatment.1 For these patients, the effects of depression can still be debilitating. These patients need a proven, safe depression treatment option.

Are some people more likely to become depressed than others?

However, the exact nature of these genetic characteristics is not known. Other factors may contribute to an individual’s likelihood of experiencing depression. Some of these risk factors include:

  • Individuals suffering from certain medical illnesses such as stroke, heart attack, cancer, Parkinson’s disease, and hormonal disorders

What are the current approved treatments for depression?

There are non-drug and drug therapies available to treat depression. Depression is often initially treated with psychotherapy (talk therapy) and antidepressant medication administered together. Although antidepressants can be effective for some patients, they do not work for everybody. Additionally, antidepressants often result in unwanted side effects.

Many patients do not receive adequate benefit from antidepressant medication and/or cannot tolerate the side effects caused by them.1 For these patients, alternative treatments that involve the use of a medical device are available. These treatments include transcranial magnetic stimulation (TMS), electroconvulsive therapy (ECT) and vagus nerve stimulation (VNS).1

What is transcranial magnetic stimulation?

Transcranial magnetic stimulation (TMS) uses short pulses of a magnetic field to stimulate nerve cells in the area of the brain thought to control mood. The pulsed magnetic field may have a positive effect on the brain’s neurotransmitter levels.
