Obsessive compulsive disorder brain chemistry psychology – Stuck in a Loop of ‘Wrongness’: Brain Study Shows Roots of OCD

Further research into these disorders of overlapping endophenotype may serve to illuminate the rest of the OCD picture as it relates to the brain structure. Due to the number of people with OCD whose parents have also been diagnosed, there is contention over whether this points to OCD as a hereditary disorder or to nurture rather than nature is a primary factor in the development of the disorder.

Zeroing in on brain differences In their paper, the U-M researchers focused on the cingulo-opercular network — a collection of brain areas linked by highways of nerve connections deep in the center of the brain. Because people with OCD respond well to treatment with antidepressants that target the brain chemical serotonin, there may be genes associated with serotonin that play a role in OCD development. That could lead their overreaction to errors to overwhelm their underpowered ability to tell themselves to stop.
