Deep Brain Stimulation Could Help Treat Depression

Some doctors and researchers believe that deep brain stimulation (DBS) can help treat depression. However, this invasive procedure has mixed results. The medical community is divided over its effectiveness, with many doctors recommending psychotherapy and other treatments instead. It is important to discuss DBS with your doctor, however, before deciding to undergo the procedure.

Deep brain stimulation alleviates depressive symptoms

Deep brain stimulation (DBS) is an effective therapy for reducing depressive symptoms. It can be administered 24 hours a day and is more effective than other treatment options. Researchers are examining whether DBS can improve the quality of life of patients suffering from depression. They are also exploring whether the treatment is better than traditional therapy.

A recent study found that DBS to brain structures mediating reward and motivation processes alleviated depressive symptoms. This procedure offers an innovative treatment option for refractory major depression. Furthermore, it has a favorable side-effect profile compared to conventional treatment options. In addition to treating depression, deep brain stimulation may also help treat addictions.

Researchers have found that DBS can relieve depressive symptoms by mimicking an electrical lesion in the brain. A number of studies conducted in different centers have indicated that the procedure can treat the most common forms of depression. However, more research is needed. Although DBS has demonstrated promising results in other medical conditions, there are some risks associated with the treatment.

Deep brain stimulation reduces depressive symptoms in TRD

Various neurophysiological studies have demonstrated that deep brain stimulation (DBS) can reduce depressive symptoms in patients with TRD. Its effects in treating depressive disorders have been linked to its ability to improve the brain’s connectivity. One of the major brain regions, the sACC, has extensive projections to various areas of the brain. One of its main pathways, called the sACC-FOC, connects to the frontal pole, midcingulate lobe, and NAcc. It is also associated with the depressive syndrome.

There are a number of candidate brain structures that may be involved in the DBS-induced reduction of depressive symptoms in TRD. Some of these include the anterior thalamic radiation, the uncinate fasciculus, and the globus pallidus pars interna. The exact targets for the treatment have not been determined. Nevertheless, DBS-induced changes in mood were noted in the responsive groups.

Deep brain stimulation is an experimental technique that reduces depressive symptoms in patients with TRD and bipolar disorder. The effectiveness of this therapy is still controversial. In one study, seven patients with TRD underwent HB-DBS. The aim was to determine the optimal settings for stimulation to improve brain activity. After a year, 50% of the subjects had responded to the therapy.

UCSF has patents related to deep brain stimulation treatment of depression

Although depression symptoms vary greatly, one commonality is that they are impacted by a deep brain stimulation treatment. Deep brain stimulation is a nonsurgical therapy that stimulates the brain with electrical currents to treat various conditions including depression. It is also used to treat epilepsy and Parkinson’s disease. The UCSF approach is different because it targets specific brain circuits with intermittent currents.

A successful achievement of these goals will create a new paradigm in the access to deep brain structures, allowing for shorter and safer operative procedures. It will also allow for precise delivery of therapies, a factor critical to their therapeutic efficacy. It will also advance the goals of the UC Discovery Program and foster an alliance with the private sector.

A personalized deep brain stimulation treatment may help long-term depression sufferers achieve better mental health and alleviate their symptoms. Researchers at the University of California San Francisco recently published their findings in the Nature Medicine journal. They identified a biomarker of the individual’s neural activity that could be used to identify the best location for delivering deep brain stimulation.

Target structures for deep brain stimulation treatment of depression

Target structures for deep brain stimulation treatment of depression are still not clearly defined. One hypothesis is that DBS is effective for treating depression by enhancing the SCC, which is activated during sad mood. Inhibiting this pathological overactivity may release patients from a chronic state of negative mood. The SCC is highly interconnected with other parts of the brain, including the hypothalamus and brainstem. Furthermore, its connections with the insula allow it to modulate neurovegetative symptoms.

There are many different brain regions that can be targeted by DBS. The most common ones are the ventral capsule/ventral striatum and the subcallosal cingulate. Other targets include the nucleus accumbens and the medial forebrain bundle. Research has shown that these areas respond well to this therapy. In fact, some treatments can even last for years.

Although there are still several challenges in determining the optimal target, researchers have made significant progress. Target structures for DBS have been identified by anatomical abnormalities in MDD. Some patients have seen a decrease in their symptoms with DBS. The results of these therapies are promising.
