Somatic Treatments for Depression

Brain stimulation (somatic) treatments for depression

There are a number of non-medication, non-therapy options for treatment-resistant depression. Somatic treatments involve stimulating the brain through the application of energy. ECT and TMS are the most well-known, but there are some more obscure options as well. And then there’s cranial electrotherapy, which isn’t in the same ballpark at all. So let’s dive in!

Electroconvulsive therapy

Electroconvulsive therapy (ECT) has a bad public reputation. People think it’s barbaric and much like what happened to Jack Nicholson’s character in One Flew Over the Cuckoo’s Nest. Modern ECT isn’t like that at all, though. You’re knocked out with anaesthetic, an electrical stimulus is applied to induce a seizure (electrically; there’s no physical seizure because of a muscle relaxant), and then you wake up a little while later.

ECT is the most effective treatment for depression, and it works far faster than medication, making it a good choice for people who are actively suicidal. A 2016 study published in Biological Psychiatry found that ECT promoted neuroplasticity and growth in areas of the brain like the hippocampus and amygdala where depression had already reduced the volume compared to normal. Smaller volumes of the hippocampus prior to ECT were associated with a greater clinical response.

The biggest downside is the potential for memory loss, which is dependent in part on how many treatments you need and whether you need unilateral or bilateral placement of electrodes during the procedure. For some people it’s not an issue, for others it’s a huge problem, and there’s a whole range of territory in between. I experienced a fair bit of memory loss, but it was a price I was willing to pay for how well it works.


Transcranial magnetic stimulation

Transcranial magnetic stimulation involves the application of a magnetic field across the brain to stimulate certain areas beneath the surface. Typically, people receive rTMS, but there is a deep TMS that can reach deeper brain structures.

Treatment is administered five days a week over 6 weeks. The patient is awake and sitting up during the treatment.

TMS can help with both bipolar and unipolar depression. It’s generally considered to be less effective than ECT.


Deep brain stimulation

Deep brain stimulation (DBS) is most often done in Parkinson’s disease, but it is sometimes used to treat depression as well. Electrodes are implanted into the brain and connected to a neurostimulator that’s implanted below the collarbone, which generates electrical signals.

Getting the electrodes implanted involves neurosurgery, which can come with complications. The scary image above shows implantation surgery. The whole contraption thingy is to keep the head steady, because I suppose you don’t want to have an oopsey while doing brain surgery.


Vagus nerve stimulation

The vagus nerve, also known as the tenth cranial nerve, runs from the brain down through the neck to the heart and several other organs. Vagus nerve stimulation (VNS) involves surgery to connect lead wires to the vagus nerve, and then attach those to an impulse generator implanted below the collarbone.

It takes several months to see a therapeutic effect, and side effects are common, so it’s not used very often. It’s far more common for the treatment of epilepsy.


Transcranial direct current stimulation

Transcranial direct current stimulation (tDCS) delivers low direct current through electrodes placed on the head, which induces electrical activity in the brain areas underneath. MRI or PET imaging may be done beforehand to determine the correct area for electrode placement. Treatments are done daily over a period of several weeks.


Cranial electrotherapy stimulation

So far, this post has covered evidence-based treatments for depression. Cranial electrotherapy stimulation (CES) deviates from that. There’s some similarity between this and tDCS, but CES uses alternating rather than direct current. This is a buy it online, do it yourself at home kind of deal. There’s a stimulator device and clips that you connect to your earlobes; these can run you upwards of $500.

What makes these devices a bad deal is that there’s no evidence that they work. They may be advertised as FDA approved, but when it comes to medical devices, FDA approval basically only says that they’re pretty convinced it won’t electrocute you. When it comes to CES devices, the FDA has said outright that there’s no evidence they work for depression.


Ah, good ol’ treatment-resistant depression. Never a dull moment. At least the transorbital lobotomy has gone by the wayside.

Speaking of which, this is a weird Canadian musical short film called Lotobotomobile, about lobotomist-in-chief Dr. Walter Freeman and his travelling roadshow (the roadshow existed, but it apparently wasn’t called the Lobotomobile).


Have you ever tried, or contemplated trying, any of these somatic treatments for depression?

  1. There was a time i desperately wanted etc. I don’t currently and never got it but i thought of it as another potential “cure” 😕 it is very hard to get where i live and so it didn’t come to fruition

  2. I had a few ECT treatments when I ended up in the hospital after trying to hang myself. It made my jaw sore, and I have gaps in my memories from around that time. BUT, I do feel like it helped me, whether is be a placebo effect or not. After some time passed, it seemed like life weighed on me a little less.

  3. I don’t understand it. I live off/on with suicidal ideation. But, it appears much of my depression is being controlled. While some days I am totally distraught from life, other days I am just blah. Most days I feel bad, but not bad enough for one of these treatments. Still, I feel terrible. Anyway, welcome to the breadth and depth of mental illness.

    1. Yeah, fun stuff. ECT is recommended less often than it probably should be, because treatment providers anticipate patients will have stigmatized beliefs around it. TMS is becoming more popular, though, although getting coverage for it isn’t necessarily easy.

  4. Interestingly, T-2 is hooking us up to that Alternating earlobe device this week. Apparently bilateral stimulation is used for trauma treatment along the lines of EMDR, which we are not a candid for due to dissociation. Maybe the bilateral stim is intended to help keep us present and to see if the sensation calms us?

    1. That definitely makes sense. Then the nature of the current itself should matter far less than the fact that you can get alternating stimulation with it.

  5. I often wish my brain would be fried to hard re-set it 😪 Apparently ECT can help with functional neurological disorder, so dubious Google sources claim! I’d be first in line to volunteer

    My therapist said it’s rarely used now as far as the UK is concerned.

  6. This was a very extensive listing of procedures that are available. I’ve looked into some of these in the past. I go through the VA for my mental health care and was only given a choice of ECT. I was scared of losing small important parts of my memory. I was worried it would somehow change me or my love for my wife. She is the most important part of my life and I could never risk changing that in any way so I turn down the opportunity for treatment with ECT. I’m not saying anything bad about ECT and I do think its important you post these techniques to bring knowledge that there is other ways than medication and therapy. Each person is unique and has to be treated that way, the more treatments out there the better for all. Thanks for you article.

    1. I had a fair bit of memory loss with ECT, because I had bilateral rather than unilateral, and I had a relatively high number of treatments. I didn’t have any changes in feelings or sense of who I was. It was very event-specific, and the worst was with my first course, and I lost memories going back a few months before starting ECT. The only interpersonal relationship that was affected was a new friend I’d made during that few-month time frame that my memory was affected; I didn’t remember who she was. Most of the memory loss was during the time I was getting ECT, which was 3 per week. My family noticed that more than I did. It was things like if we were going out for dinner that evening on a pass from hospital, I might remember that, but ask five times what restaurant we were going to. The biggest thing, though, was that it helped, which for both me and my family was a much bigger deal than me forgetting a few things.

  7. My psychiatrist uses ECT. While in treatment I have seen a person after they wake up and how they looked and sounded. It was rather shocking because they had a far away look.
    The therapy was done in a room in the Mental Health Ward just off of the common room. I never heard any noise, but you knew what had happened when the person rejoined the rest of us in the common area.
    Not really sure how I feel about it. If I needed it and have my confidence with my psychiatrist I believe I wouldn’t be fearful about it.

  8. You definitely don’t want to have an oopsie during brain surgery, lol
    I was moderately pushed to try ECT while in inpatient treatment, but I told them I was reluctant to go that route without trying a few more meds, first. To be honest, I was just scared of it, despite knowing that it’s not at all what it can be portrayed to be in the media/public perception. I would consider it if ketamine stopped working/ I stopped having access to it.

  9. As you probably know Ashley, I’ve worked with many patients who’ve had ECT and swear by it. My mum’s had ECT twice and it worked for her too.

    My son (Dr Ricci Hannah) did lots of studies on TMS, here’s just one, if anyone’s interested: https://pubmed.ncbi.nlm.nih.gov/32306064/

    I’ve heard of the others, particularly DBS as one of our patients had it for Parkinsons. He didn’t find it helpful.

  10. This post is very educational. There are we things in here I didn’t know before I read this that I now know. Which is great.

    Maybe if you shorten any future posts you make into smaller ones, it’d be easier to understand. And it wouldn’t be so much as “too much information”. I don’t mean this in a bad way. I just kind of lost track half way through.
