  • For individuals resistant to traditional treatments, electroconvulsive therapy (ECT) has emerged as a viable option, especially for severe cases.

Newer Treatments

As the landscape of mental health treatment continues to evolve, novel therapies are being explored to address major depressive disorder. Here are some innovative approaches:

  • Ketamine: This drug, originally used as an anesthetic, has shown promising results in restoring brain connectivity and alleviating depressive symptoms in a relatively short period.
  • Psychedelics: There is a growing body of evidence supporting the use of psychedelic drugs like psilocybin and LSD in treating depression, either alone or in combination with traditional antidepressants.
  • Transcranial Magnetic Stimulation (TMS): TMS, a non-invasive procedure involving magnetic currents, has demonstrated efficacy in managing treatment-resistant depression by modulating brain activity.
  • Deep Brain Stimulation (DBS): Through implanting electrodes in specific brain regions, DBS offers a targeted approach to alleviating depression symptoms, though it carries surgical risks.

Emerging Technologies in Depression Treatment

Looking ahead, the future of treating major depressive disorder holds exciting possibilities with the advent of cutting-edge technologies. Here are some advancements on the horizon:

  • Minimal or non-invasive DBS: Researchers are exploring less invasive methods of delivering deep brain stimulation to patients, such as implanting electrodes without surgery.
  • Next-generation therapies: Programs like DARPA’s initiative are investigating futuristic treatments involving small transmitters and stimulators that can be administered through innovative delivery methods.

In Conclusion

As the understanding of major depressive disorder deepens and technology continues to advance, the future looks bright for individuals struggling with this condition. With a range of evidence-based and emerging treatments at our disposal, there is hope for improved outcomes and quality of life for those affected by depression.

By James Giordano, PhD, as told to Kara Mayer Robinson

Over the past 20 years, we have seen great advances in treatment options for major depressive disorder.

We now understand that depression is not the same for everyone. The idea is to identify and diagnose what’s going on in a person’s neurochemistry so we can target our treatment in a way that works specifically for them.

Advances in evidence-based treatment

Pharmacotherapy has advanced a lot in recent years. We have improved the scope and focus of drug therapy by developing more selective or specialized antidepressants and combining them in new ways, with fewer side effects.

Current drug therapy may include newer medications such as citalopram (Celexa) and escitalopram (Lexapro), as well as existing medications such as fluoxetine (Prozac) and sertraline (Zoloft).

It tends to work best when combined with psychotherapy, as supported by extensive evidence. We now know that the most effective and efficient types of therapy appear to be cognitive behavioral therapy and psychodynamic therapy.

For people whose depression is resistant to psychotherapy and pharmacotherapy, doctors may use electroconvulsive therapy (ECT). The current version of ECT is much more specific and has fewer side effects. It is usually reserved for people who have severe, drug-resistant depression with bipolar features.

Newer treatments

Many new therapies have been introduced that have brought significant improvements for patients.

ketamine

A newer therapy involves the drug ketamine, which has been used in the past as an anesthetic and has great benefits. It’s a relatively new approach. It has been around for about 5 years.

Ketamine therapy restores brain network and node connectivity to reduce, if not eliminate, many depressive signs and symptoms. Many patients experience lasting relief and, in some cases, recovery.

Ketamine therapy may involve as little as a single dose. Or it could be multiple doses over a short period of time. But it must be done under medical supervision. Although it is usually an outpatient therapy, proper dosage and support for the patient using ketamine is essential.

It is not the first drug of choice because it has quite profound effects on the brain and should be used with caution. It is currently used for severe, treatment-resistant depression. But there is an ongoing debate that people with severe depression might do well if they used it earlier in treatment.

I think we will see more use of ketamine in the future, especially for those who are not helped by other treatments.

Psychedelics

There is increasing evidence for the use of psychedelic drugs to treat major depression.

Drugs such as psilocybin, commonly known as mushrooms, and LSD (lysergic acid diethylamide) can change properties of brain chemistry implicated in depression.

Microdoses or milliloses of these medications can be very effective, either alone or when used with antidepressants. They may improve symptoms, behavior, and function. They are usually fast-acting, but for some people the effects do not last long.

Psychedelics are still viewed with relative stigma and are a controlled substance. You need to find the right microdose and schedule to get the best effect. Not all doctors are trained, comfortable, or willing to provide psychedelic drugs.

Another drawback is that people may try to self-medicate, which is very difficult. This is a very specific method that requires clinical skill.

More research is needed. We need medication-based evidence on the use and value of psychedelics in the treatment of certain types of depression.

Transcranial magnetic stimulation (TMS)

TMS is interesting, which consists of passing a very weak magnetic current through the skull. It works like a dimmer switch to change the brain’s electrical activity and reduce the signs and symptoms of depression.

There is very promising research showing that repetitive TMS can be very effective in treating certain forms of treatment-resistant depression. It is very easy to perform, can be adapted to the needs of each patient and, many times, has a quick and long-lasting response. It can be used alone or combined with psychotherapy or pharmacological treatment.

But while the effects of TMS are strong, they can wane over time. It may require several sessions and you must find a doctor who is qualified and trained to administer EMT.

Deep brain stimulation (DBS)

Deep brain stimulation is a new and emerging treatment that involves implanting electrodes to target specific areas of the brain. It can be adjusted for each individual patient to more effectively manage their symptoms and signs of depression.

DBS was first tested in 2005. Since then, science has advanced considerably with the help of the BRAIN Initiative, an NIH program aimed at revolutionizing our understanding of the human brain. We now have a better understanding of how to target the brain more precisely, which can lead to better results. More research will help even more.

DBS appears to restore brain network activities. Over time, the brain activity involved in depression can turn off, meaning patients remain in remission. There is evidence to suggest that deep brain stimulation has long-lasting effects.

An interesting effect we have seen in some patients is how significantly their prognosis changes. Some people seem more outgoing and exuberant, with new vigor and even changing interests. It’s difficult to know if these changes are a side effect of deep brain stimulation or if they are a result of feeling the burden of depression eased. It’s very interesting.

A disadvantage of DBS is that it is neurosurgery, so there is a risk of infection and bleeding. It is rare, but there is also a risk of the electrodes becoming misplaced or misdirected.

Other disadvantages include side effects and cost. Insurance companies do not uniformly cover DBS. As technology improves, maintenance and upkeep will be required and can be costly.

I think DBS is the future. When it works, it really works.

on the horizon

Emerging technology is moving toward minimal or non-invasive deep brain stimulation (DBS).

There is cutting-edge technology that involves non-surgical implantation of electrodes. A program at DARPA, an agency that supports the BRAIN Initiative, is studying small transmitters and stimulators that can be introduced into the bloodstream, inhaled or even swallowed, and then guided to the brain.

Other groups are looking at minimally invasive approaches that can be done in a doctor’s office. All it requires is a very small hole in the scalp, where doctors insert liquid electrodes and then electromagnetically guide them to the brain. When they reach the brain, they harden.

I think this is the future. It may be ready in some form in 5 to 10 years.
