Millions of people struggle with depression, a potentially life-threatening illness that can cause families to dissolve, jobs to be lost and suicide attempts. While traditional medications usually take four to six weeks to take effect, repetitive transcranial magnetic stimulation (rTMS) has shown success improving symptoms in 50 percent of treatment-resistant depression cases and even 30% reaching full remission.<\/p>\n
ECT can help those experiencing severe depression that doesn’t improve with medication or psychotherapy, as well as people living with bipolar disorder who exhibit symptoms of mania. Both rTMS and ECT are noninvasive outpatient treatments.<\/p>\n
Depression affects brains by keeping overactive emotional centers under control; normally this would be accomplished via an executive function in the prefrontal cortex – however this switch has become weak in people with treatment-resistant depression (TRD). Researchers conducted a recent clinical trial where they used electrical brain stimulation to strengthen participants’ switches for depression relief by up to 50%. This technique, known as Theta Burst Stimulation or TBS, proved highly successful. Combining TMS (repetitive transcranial magnetic stimulation -rTMS) with another treatment option which offers more frequent sessions and intense pulses can produce a noninvasive treatment that can alleviate depression symptoms in as few as six weeks, with reduced clinic visits than its standard protocol counterpart.<\/p>\n
TBS is similar to vagus nerve stimulation (VNS), an established treatment option used for decades. VNS uses a pulse generator roughly the size of a stopwatch to alter how nerves communicate with the brain, helping regulate heart rate, breathing, basic functions and mood regulation as well as mood regulation. VNS has even proven successful against certain forms of depression such as TRD.<\/p>\n
Williams modified VNS hardware for noninvasive, more targeted TBS known as Stanford neuromodulation therapy (SNT). He and his colleagues noticed that people suffering severe depression showed different electrical activity in the sadness control circuit in their left dorsolateral prefrontal cortex (DLPFC) than healthy controls, suggesting they may require electric current infusion to reset this pathway and alleviate symptoms, similar to how pacemakers reset irregular heartbeats. By sending electrical pulses directly through DLPFC they were able to retrain this circuit and reduce symptoms by sending counter-pulses of electric current through DLPFC they could reset this circuit and reduce symptoms like pacemakers reset irregular heartbeats by sending electric current pulses through that region DLPFC they discovered they could retrain it and reduce symptoms similar to how pacemakers reset irregular heart beat irregularly by sending electrical current pulses via DLPFC sending counterpulses they could retrain it and reduce symptoms – just like how pacers reset irregular beat heartbeats by sending electric current pulses they could send counter pulses retrain it and reduce symptoms – just like pacemakers reset irregularly beating heart beats out.<\/p>\n
SNT measures brain activity associated with depression, then triggers a DLPFC-stimulating electrode to release a short pulse of electric current for just several seconds before recording electrode detects that activity has returned to normal and the stimulating one is turned off – this approach provides faster and more targeted treatment than continuous stimulation provided by traditional DBS implants to treat movement disorders such as Parkinson’s disease.<\/p>\n
Depression affects millions of people worldwide, leading to lost productivity, damaged relationships and an elevated suicide rate. While psychotherapy and antidepressant medication often relieve symptoms for many individuals, some with severe depression who remain resistant to treatment – known as treatment-resistant patients – continue to experience debilitating symptoms and endure adverse side effects from medications they’re prescribed and face an elevated suicide risk; finding therapy suitable for them may seem like an endless search process.<\/p>\n
TMS may be an effective treatment option for those struggling to find relief from depression through medication or psychotherapy alone. TMS works by targeting specific brain circuits that control mood. By stimulating brain activity in these areas with magnetic pulses, TMS aims to alleviate depression while simultaneously improving energy and concentration – even leading to remission within weeks in some cases.<\/p>\n
Researchers are expanding TMS therapy’s use in depression treatment over the past 20 years by developing Stanford Neuromodulation Therapy, or SAINT. A first double-blind clinical trial using SAINT involved 29 people suffering from treatment-resistant depression; half received this new method while the other half received placebo treatments to rule out placebo effects; those receiving SAINT experienced significant reductions in depression, anxiety and suicidal thoughts as well as dramatic improvements – results which have since been replicated across subsequent trials.<\/p>\n
SAINT is an outpatient procedure that’s noninvasive and safe for people who remain awake and alert during sessions. Unlike electroconvulsive therapy or deep brain stimulation (DBS) with implanted electrodes, SAINT uses sound waves instead to reach similar areas in the brain targeted by traditional treatments such as electroconvulsive therapy or DBS with electrodes implanted directly onto them. Based on focused ultrasound guided by MRI technology, this method allows SAINT to reach these deeper regions quickly without anesthetics or sedations and over an extended time span so making SAINT an ideal option for working professionals or those juggling family commitments alike.<\/p>\n

King’s College London in conjunction with University of East London and Flow Neuroscience have discovered that direct brain stimulation devices provide a safe and effective method for treating depression at home. A clinical trial comprising 174 participants suffering moderate to severe depression who either received active treatment using the Flow Neuroscience transcranial direct current stimulation device or an inactive control device did not produce any stimulation saw greater rates of response and remission for those receiving active treatment using tDCS than for placebos.<\/p>\n
Electroconvulsive therapy (ECT) or deep brain stimulation with implanted electrodes requires no anesthesia or sedation, making tDCS an easy-to-use at-home therapy option that complements existing treatments such as medication and talking therapies to enhance results and sustain improvements.<\/p>\n
