Since then, it’s also been allowed as treatment for dystonia and OCD under a humanitarian device exemption, and it’s also been under investigation for other conditions like major depressive disorder, Alzheimer’s disease, and binge-eating disorder.\n<\/p>\n \nPlacement of the device can take up to two separate surgeries: One to implant the electrodes into the affected brain areas (those used in decision-making and balancing emotions); the other to place a neurostimulator, connected to the electrodes, under the skin, usually near the collarbone.\n<\/p>\n \nOnce the two are connected, the neurostimulator sends electric pulses to the electrodes in the brain, which can help control abnormal brain activity. In OCD, those electric pulses can also adjust for chemical imbalances in the brain that cause symptoms.\n<\/p>\n \nFor the new research, Dr. Sheth and his team assessed the current evidence surrounding the efficacy of DBS in alleviating OCD. To do this, researchers conducted a systematic review and meta-analysis of previously published research and re-evaluated it.\u00a0\n<\/p>\n \n\u201cTo really understand how well it may work, we have to do these meta analyses, which takes data from many studies and puts [it] all together so we can have a decent sample size,\u201d said Dr. Sheth. Looking at all the available research and analyzing it in this way can help pinpoint how effective the procedure really is, he added.\n<\/p>\n \nThe researchers included 31 studies conducted between 2005 and 2021 with 345 adults, average age 40, who had struggled with severe to extreme OCD for nearly 25 years. In addition to the OCD, many of the patients had depression, anxiety or personality disorders, which commonly accompany the OCD diagnosis. The follow-up was about two years.\n<\/p>\n \nOverall, 66% of the patients responded to DBS, the researchers found, with the patient\u2019s symptoms reduced by about half.\u00a0\n<\/p>\n \nNoticeable results and improvement are typically seen in a few months, according to Dr. Sheth, and with many patients, the DBS also improves their coexisting depression. <\/em>About 1 in 5 had a serious side effect, such as stroke or a new OCD symptom.\n<\/p>\n \nAbout 10% or 20% of the estimated 7 million of OCD patients are severe enough to be candidates for DBS, said Dr. Sheth\u2014that translates to about 7,000 people.\n<\/p>\n All of the Facts You Need to Know About OCD<\/span><\/p>\n <\/span> <\/p>\n \nThe new research conducted by Dr. Sheth and his team confirms what is seen in clinical practice, according to Darin Dougherty, MD, director of the Division of Neurotherapeutics at Massachusetts General Hospital and associate professor of psychiatry at Harvard Medical School.\n<\/p>\n \n\u201cThe treatment is reserved for patients who have no benefit from all the conventional treatments,\u201d said Dr. Dougherty, who was not involved in the study, but is an expert in DBS and OCD.\n<\/p>\n \nThose conventional treatments often include first-line therapies, like psychotherapy and certain medications including antidepressants and psychiatric drugs. Other treatment options\u2014exposure and response prevention (ERP) and transcranial magnetic stimulation (TMS) therapies\u2014may also be tried first.\n<\/p>\n \nBut in people with severe OCD for whom those therapies did not work, a 66% response rate is not only remarkable, said Dr. Doherty, but \u201clife-changing.\u201d\n<\/p>\n \n\u201cThese patients are debilitated,\u201d said Dr. Dougherty.\n<\/p>\n \nDr. Sheth mentioned one woman whose OCD got so severe that she wasn\u2019t able to leave her bedroom. Though she had sought treatment from psychiatrists and was prescribed several treatments, nothing seemed to quell her severe symptoms\u2014until she tried DBS.\n<\/p>\n \n\u201cShe did a total 180,\u201d Dr. Sheth said. \u201cHer depression improved first, within weeks. Her mood was better, her anxiety less,\u201d he added, and within months, her OCD symptoms had decreased greatly.\n<\/p>\n OCD: Signs and Symptoms<\/span><\/p>\n <\/span> <\/p>\n \nDeep brain stimulation is a commitment, with ongoing care and monitoring needed.\n<\/p>\n \nAfter implantation of the device, patients must avoid overexertion as healing progresses. At about four weeks, the physician turns on the neurostimulator. It can take a few months after that to notice results, according to the device maker.\n<\/p>\n \nRegular follow up visits to the clinic are needed so the neurostimulator programming can be checked and adjusted as needed. \u201cIt\u2019s a lifelong treatment,\u201d said Dr. Sheth.\n<\/p>\n \nCosts for DBS vary greatly, said Dr. Sheth, noting that it\u2019s dependent on the hospital and the location. The device itself costs about $30,000, plus the costs for hospitalization, follow up visits and other services.\n<\/p>\n \nInsurance coverage is usually made on a case-by-case basis by private insurers as well as by Medicare and Medicaid, according to Medtronic, the maker of the device approved for OCD.\n<\/p>\n \n\u201cWe fight hard to get insurance to cover,\u201d Sheth said. \u201cMost of the time we are successful.\u201d\n<\/p>\n \nAs promising as the DBS is for OCD, Sheth said there\u2019s a long way to go to better help those severely affected. Reducing the stigma of mental health issues is still needed, he said. Access to the device must be expanded. And insurance coverage should be better.<\/p>\n","protected":false},"excerpt":{"rendered":" Photo: Getty Images Fast Facts Deep brain stimulation (DBS) may be a helpful treatment option for people with severe obsessive-compulsive disorder (OCD).
