Event Description

Luyten, l., hendrickx, s., raymaekers, s., gabriels, l., nuttin, b.Electrical stimulation in the bed nucleus of the stria terminalis alleviates severe obsessive-compulsive disorder.Molecular psychiatry.2015.1-9.Doi: 10.1038/mp.2015.124.Summary: in 1998, we proposed deep brain stimulation as a last-resort treatment option for patients suffering from severe, treatment-resistant obsessive-compulsive disorder (ocd).Here, 24 ocd patients were included in a long-term follow-up study to evaluate the effects of electrical stimulation in the anterior limbs of the internal capsule (alic) and bed nucleus of the stria terminalis (bst).We find that electrical stimulation in the alic/bst area is safe and significantly decreases obsessions, compulsions, and associated anxiety and depressive symptoms, and improves global functioning in a blinded crossover trial (n = 17), after 4 years (n = 18), and at last followup (up to 171 months, n = 24).Moreover, our data indicate that bst may be a better stimulation target compared with alic to alleviate ocd symptoms.We conclude that electrical stimulation in bst is a promising therapeutic option for otherwise treatment resistant ocd patients.Reported events: patient (b)(4): one (b)(6) female patient with bilateral deep brain stimulation (dbs) targeting the bed nucleus of the stria terminalis (bst) to treat obsessive compulsive disorder (ocd) experienced a fracture of their ankle, foot, arm, leg, hand, or rib 24 months after implantation.This was considered ¿probably not stimulation induced.¿ further information has been requested; a supplemental report will be submitted if additional information is received.
