When traditional treatments fail to help patients with severe obsessive-compulsive disorder (OCD), an implant that zaps the brain with electrical pulses just might, a new research review shows.
It found that the remedy — known as “deep brain stimulation,” or DBS — can offer significant relief to as many as two-thirds of such patients. On average, it can reduce OCD-triggered symptoms by nearly half, the review found.
“[OCD involves] intrusive and bothersome thoughts that the individual cannot silence, and compulsions that are repetitive, ritualistic behaviors performed to reduce the anxiety produced by the compulsions,” said study author Dr. Sameer Sheth. He is an associate professor of neurosurgery at Baylor College of Medicine in Houston.
An estimated 3% of the global population is thought to be affected. For those with severe OCD that is uncontrolled, the symptoms can be “all-consuming,” Sheth said. Examples of OCD include repeated handwashing, ordering and arranging, repeating words in one’s head, and checking and double-checking.
“They can prevent the person from being able to perform other necessary activities of life, and therefore be extremely disabling,” Sheth said. “Some people cannot leave their room or home because of the cleaning rituals that would be necessary to re-enter, or cannot interact with others because of incessant taboo thoughts.”
The good news is that a combination of behavioral therapy and standard antidepressants — such as serotonin reuptake inhibitors (SRIs) — help many individuals.
The bad news: “About 10% to 20% do not respond” to those treatments, Sheth said.
