We used several metrics of variability to extract unsupervised features from video recordings of patients before and after deep brain stimulation (DBS) treatment for major depressive disorder (MDD). Our goal was to quantify the treatment effects on facial expressivity. Multiscale entropy (MSE) was used to capture the temporal variability in pixel intensity level at multiple time-scales. A dynamic latent variable model (DLVM) was used to learn a low dimensional (D = 20) set of dynamic factors that explain the observed covariance across the high-dimensional pixels (M = 30 × 30) within each video frame and across time...

BACKGROUND: Preliminary studies report no negative and a possible positive impact of deep brain stimulation (DBS) on cognition of patients with treatment-resistant depression (TRD). However, these studies neither controlled for practice effects nor compared active with sham stimulation. METHOD: To address these limitations, we compared 25 TRD patients, who underwent DBS of the ventral anterior limb of the internal capsule (vALIC), with 21 healthy controls (HCs) matched on gender, age and education level...

Depressive symptoms may occur after Deep Brain Stimulation (DBS) in the subthalamic nucleus. This is often explained by reduced pharmacological treatment after surgery, and not as a direct effect of DBS. Pallidal DBS seems not to be associated with such side effects and have not, to our knowledge, previously been reported. We present a patient with acute depressive symptoms induced by pallidal DBS. We believe this case strengthen the hypothesis that the basal ganglia and structures involved in the functional connectome of these nucleuses play a role not only in regulation of movement but also in regulation of mood...

: Dysfunction of the orbitofrontal (OFC) and anterior cingulate (ACC) cortices has been linked with several psychiatric disorders, including obsessive-compulsive disorder, major depressive disorder, post-traumatic stress disorder, and addiction. These conditions are also associated with abnormalities in the anterior limb of the internal capsule, the white matter bundle carrying ascending and descending fibers from the OFC and ACC. Fruthermore, deep brain stimulation (DBS) for psychiatric disorders targets these fibers...

The lack of efficacy of deep brain stimulation (DBS) of subcallosal cingulate (SCC) in treatment resistant depression (TRD) may be due in part to suboptimal targeting. In two patients treated with SCC DBS for TRD we assessed the voxel-wise probabilistic connectivity of SCC with four tractography-defined target areas implicated in depression, thereby identifying the tractography-optimized target (TOT). Compared to the non-responder, the responder's DBS leads were implanted and stimulation was delivered closer to the TOT...

BACKGROUND: Depression is common in Parkinson's disease (PD) and adversely affects quality of life. Both unilateral and bilateral subthalamic (STN) deep brain stimulation (DBS) effectively treat the motor symptoms of PD, but questions remain regarding the impact of unilateral STN DBS on non-motor symptoms, such as depression. METHODS: We report changes in depression, as measured by the Hamilton Depression Rating Scale (HAMD-17), in 50 consecutive PD patients who underwent unilateral STN DBS...

PURPOSE: Bilateral deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) reduces seizures and is relatively safe but may be accompanied by complaints of memory problems and depression. This study examined incidence of memory and depression adverse events (AE) in the SANTE study blinded phase and their relationship to objective neurobehavioral measures, baseline characteristics, quality of life and long-term neurobehavioral outcome. METHOD: The neurobehavioral AE and neuropsychological data from a previously reported prospective randomized trial (SANTE) were analyzed...

BACKGROUND: Extensive clinical research has shown that the efficacy and cognitive outcomes of electroconvulsive therapy (ECT) are determined, in part, by the type of electrode placement used. Bitemporal ECT (BT, stimulating electrodes placed bilaterally in the frontotemporal region) is the form of ECT with relatively potent clinical and cognitive side effects. However, the reasons for this are poorly understood. OBJECTIVE: This study used computational modelling to examine regional differences in brain excitation between BT, Bifrontal (BF) and Right Unilateral (RUL) ECT, currently the most clinically-used ECT placements...

Nucleus accumbens (NAcc) has been implicated in several psychiatric disorders such as treatment resistant depression (TRD), and obsessive-compulsive disorder (OCD), and has been an ongoing experimental target for deep brain stimulation (DBS) in both rats and humans. In order to translate basic scientific results from rodents to the human setting a large animal model is needed to thoroughly study the effect of such therapeutic interventions. The aim of the study was, accordingly, to describe the basic anatomy of the Göttingen minipig NAcc and its retrograde connections...

Subcortical band heterotopia is a neuronal migration disorder that may cause refractory epilepsy. In these patients, resective surgery has yielded inadequate results. Deep brain stimulation of the anterior nuclei of the thalamus has been used for the treatment of refractory epilepsy with good results. We describe the first two patients with subcortical band heterotopia who were submitted to deep brain stimulation of the anterior nuclei of the thalamus, with evaluation of seizure outcome after 12 and 18 months of follow-up...

BACKGROUND: Although a significant subset of patients with major depressive disorder (MDD) fail to respond to medical or behavioural therapy, deep brain stimulation (DBS) applied to the subgenual cingulate cortex (SCC; sg25) has been shown to reduce depressive symptoms in a subset of patients. This area receives projections from neurons in the CA1 region and subiculum of the hippocampus (HC), a brain region implicated in the pathobiology and treatment of MDD. OBJECTIVE: To assess whether high frequency stimulation (HFS) of the infralimbic cortex is associated with changes in cellular morphology in the HC...

OBJECTIVE: Deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VC/VS) region has shown promise as a neurosurgical intervention for adults with severe treatment-refractory obsessive-compulsive disorder (OCD). Pilot studies have revealed improvement in obsessive-compulsive symptoms and secondary outcomes following DBS. We sought to establish the long-term safety and effectiveness of DBS of the VC/VS for adults with OCD. MATERIALS AND METHODS: A long term follow-up study (73-112 months) was conducted on the six patients who were enrolled in the original National Institute of Mental Health pilot study of DBS for OCD...

Lei Liu, Wataru Ito, Alexei Morozov
The observational fear (OF) paradigm in rodents, in which the subject is exposed to a distressed conspecific, elicits contextual fear learning and enhances future passive avoidance learning, which may model certain behavioral traits resulting from traumatic experiences in humans. Because these behaviors affected by the OF, require dorso-medial prefrontal cortex (dmPFC), we searched for synaptic adaptations in dmPFC resulting from OF in mice by recording synaptic responses in dmPFC layer V pyramidal neurons elicited by repeated 5 Hz electrical stimulation of dmPFC layer I, or by optogenetic stimulation of specific interneurons ex vivo one day after OF...

Stereotactic subcaudate tractotomy has previously been suggested to be an effective treatment for depression. This is the first study to report the use of gamma-knife subcaudate tractotomy for treatment-resistant depression. A 49-year-old woman with major depressive disorder had been treated for 30 years, with nine suicide attempts during that time. The right and left target maximum diameter was 11 mm within 50 % isodose lines. The target was located more posteriorly and inferiorly than the subgenual cingulate target typically used for deep-brain stimulation...

BACKGROUND: Deep brain stimulation (DBS) via anatomical targeting of white matter tracts defined by diffusion tensor imaging (DTI) may be a useful tool in the treatment of pathologic neurophysiologic circuits implicated in certain disease states like treatment resistant depression (TRD). We sought to determine if DTI could be used to define the stria medullaris thalami (SM), the major afferent white matter pathway to the lateral habenula (LHb), a thalamic nucleus implicated in the pathophysiology of TRD...

BACKGROUND: Deep brain stimulation (DBS) has been shown to be effective for parkinsonian symptoms poorly responsive to medications. DBS is typically well-tolerated, as are the maintenance battery changes. Here we describe an adverse event during a battery replacement procedure that caused rapid onset of severe depression.

Depression has a high lifetime prevalence and recurrence rate, with more than one-third of affected patients experiencing treatment-refractory depression. These individuals should benefit from additional treatment options such as deep brain stimulation (DBS), a research-grade intervention. DBS is being investigated for its efficacy in treatment-refractory cases. We reviewed the English-language literature published between the years 2010 and 2015 regarding the utility of DBS for patients with treatment-refractory depression...

Repetitive transcranial magnetic stimulation (rTMS) is an emerging non-pharmacological approach to treating many brain-based disorders. rTMS uses electromagnetic coils to stimulate areas of the brain non-invasively. Deep transcranial magnetic stimulation (dTMS) with the Brainsway H1-coil system specifically is a type of rTMS indicated for treating patients with major depressive disorder (MDD) who are resistant to medication. The unique H1-coil design of this device is able to stimulate neuronal pathways that lie deeper in the targeted brain areas than those reached by conventional rTMS coils...
