A new study identifies areas of the brain involved in OCD


  • New research has identified areas of the brain involved in & # 39; obsessive-compulsive disorder, or OCD.
  • The researchers analyzed brain scans of nearly 500 people with and without OCD.
  • They found that, compared with & # 39; those without OCD, people who have the condition have more activity in brain areas involved to recognize mistakes, but less activity in brain areas that help stop errors.
  • The finding can & # 39; lays the foundations for better treatment & # 39; OCD, said the authors.

New research to analyze the brains of & # 39; almost 500 people can & # 39; provide clues to help experts better deal with obsessive-compulsive disorder (OCD), the mental health condition characterized by recurring and uncontrollable thoughts and behaviors.

The researchers picked results & # 39; 10 previous studies comparing people with and without OCD. F & # 39; such studies, participants underwent functional scans MRI looked at their brain activity during two functions: errors in processing and inhibitory control, a process that allows control & # 39; behaviors and thoughts.

Their results, published Thursday in Biological journal Psychiatry, showed that – compared to & # 39; people without the condition – individuals with & # 39; OCD had more activity in brain areas involved to recognize errors, but lower activity in brain areas involved in & # 39; of & # 39; stop action, according to a statement of & # 39; University & # 39; Michigan on research.

"These results show that, in & # 39; OCD, the brain responds too much for mistakes, and little to stop signs," said Luke Norman, PhD, leading author of the study & # 39; research Postdoctoral University of & # 39; Michigan.

Research focused on cingulo-opercular network, set & # 39; areas of the brain that acts as a "monitor" for mistakes and need to stop the action, the statement added. The new analysis suggests that the brains of patients with & # 39; & # OCD payable in 39; compulsive "loops", the authors of the study wrote. Even if the brain thinking or behavior flags & # 39; OCD as bad, can & # 39; does not have the power to stop it.

Generally, those with OCD m & # 39; have control over their obsessions (unwanted thoughts that cause distress) and compulsions (behaviors that arise with & # 39; response to those obsessions), even if they recognize those thoughts and excessive behavior, according to the National Institute of Mental Health. (For example, a common obsession is fear & # 39; of & # 39; germs or contamination, and common compulsions include excessive handwashing or cleaning).

The OCD causes are still unknown, but new research suggests that abnormalities of specific processing errors deep in the brain can & # 39; play a role in the condition.

Experts have suspected that these abnormalities were involved in OCD, said Norman in the statement, but not "shown by & # 39; conclusive way" because individual studies had a small number of & # 39; participants.

"By combining data from ten studies, and nearly 500 patients and volunteers & # 39; health, we can see how the brain circuits have ipotetizzati are crucial for OCD are indeed involved in disorder", he added .

The new research does not prove that the observed differences in the brain in patients with & # 39; OCD are definitive cause of the condition. The data used by researchers to show whether those differences can be cause or result & # 39; OCD, the university statement explained.

"There is a need & # 39; further work to better understand how these performance and abnormalities of brain function have x & # 39; share with symptoms & # 39; OCD", the authors wrote in the paper.

But knowing more about the brains of patients with OCD may help researchers better address the future treatment.

For now, treatment & # 39; OCD typically includes psychotherapy, medications, or a combination of both, but some patients continue to struggle with & # 39; symptoms, according to NIMH.

"F & # 39; of & # 39; cognitive behavioral therapy for OCD sessions, we strive to help patients identify, confront and resist their compulsions … but it only works in & # 39; about half of the patients," the of psychiatry -professur of & # 39; University & # 39; Michigan Kate Fitzgerald, co-author of the paper, said in the statement. "Through & # 39; such findings, we hope that we can make more effective CBT, or guiding hand new treatments."

"This is a bold and profound problem & # 39; behavior," it added. "The OCD is a medical problem, and not the fault of & # 39; someone.
