Deep brain stimulation of the lateral habenula in treatment resistant major depression

Sartorius, Alexander, Henn, Fritz A.·2007·Medical Hypotheses

Abstract

The burden of depression as a severe illness with high suicidality and prevalence is immense. Despite substantial advancement in psychopharmacology and psychotherapy over the last decades a residual group of very ill patients with a chronic disease and high suicidal risk remains. Modern theories about the pathophysiology of depression are derived from studies examining the mechanism of antidepressants influencing the serotonergic (5-HT) and noradrenergic (NE) systems. Serotonergic fibers originate from the dorsal raphe nuclei (DRN), noradrenergic fibers from the locus coeruleus (LC). Both nuclei represent relatively small brain regions and both are controlled to some extent by the habenular complex. We propose the hypothesis of an overactivation of the habenula in human major depressive episodes (MDE's). Increased activation of the lateral habenular nucleus leads to the down regulation of the serotonergic, noradrenergic, dopaminergic systems and stimulation of the hypothalamic-pituitary-adrenal (HPA) axis. Functional inhibition of the lateral habenula via deep brain stimulation (DBS) has antidepressive properties. The hypothesis is based on the findings of a clinical imaging study examining the habenular after tryptophan depletion and on several animal studies which are discussed. Providing that our hypothesis will be validated by an analogous tyrosine depletion study and additional preclinical studies, the next logical step would be to directly test our hypothesis in patients. Possible criteria for patient selection, ethical issues and locus of DBS are carefully discussed.

  • Over-activation of the lateral habenula has been proposed to be involved in depression and as a site of antidepressant action of conventional antidepressant drugs.

    “The lateral habenula signals negative valence to monoaminergic systems and over-activation of the lateral habenula has recently been proposed to be involved in depression as well as to be a site of antidepressant action of conventional antidepressant drugs (Proulx et al., 2014; Sartorius and Henn, 2007).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
