How Obsessive Compulsive Disorder Affects the Brain Understanding how obsessive compulsive disorder affects the brain can help you manage the condition and make treatment more effective.

Compulsions can include: Counting things over and over again Excessive washing and cleaning Arranging things in a particular or symmetrical way Checking and rechecking such as continually checking that the door is locked or that the oven is off Erasing, rewriting, or re-doing things Repeating words, phrases, or questions more Touching, tapping, or stepping in an unusual or certain way Mental compulsions such as counting and praying Frequent, excessive reassurance-seeking e.
Obsessive Compulsive Disorder Can Cause Communication Problems in the Brain Researchers know that obsessive-compulsive disorder is a result of communication problems in the brain. Generally, areas of the brain that have high amounts of grey matter help you: Control impulses Manage your senses Process information, thoughts, and feelings Develop, regulate, and exhibit motor skills like talking, writing, reaction time, balance, coordination, and drawing Unfortunately, obsessive-compulsive disorder diminishes the amount of grey matter in the brain, making people with OCD less able to control their impulses.
Gyri are the folds or bumps in the brain. The superior frontal gyrus helps regulate and mediate cognitive functions. Having less grey matter in this part of the brain prevents people with OCD from responding logically to obsessive thoughts. Diminished grey matter in this region of the brain also stops the brain from suppressing impulsive responses and habits, making people with OCD feel like they have to continue their compulsions and rituals. Medial orbitofrontal cortex.
A subregion of the prefrontal cortex, the medial orbitofrontal cortex, or mOFC, plays an important role in the decisions you make. In the first study, either a greater number of serotonin reuptake transporters increased serotonin reuptake and decreased serotonin availability, or the transporter system may have adapted to increased serotonin turnover. Endogenous serotonin systems may attempt to suppress the resulting released innate behaviors, and SRIs may facilitate this suppression. On the other hand, the results from the second study discussed here suggest that changes in serotonin activity are not inherent in all cases of OCD or, perhaps, that success in mobilizing endogenous serotonergic neurotransmission is dependent on other features of the disorder.
Pogarell O et al. Elevated brain serotonin transporter availability in patients with obsessive-compulsive disorder. Biol Psychiatry Dec 15; Simpson HB et al. A key gene for this process is hSERT which has the instructions for making a serotonin transporter. To put it simply, their nerve cells are whispering when they should be speaking out loud.
In order to allow the nerve to recover and receive the next message, the body has a clever way of removing the neurotransmitter from the receptors, and allowing it to be taken back into the originating nerve re-uptake.
The SSRIs slow down the collection of serotonin by transporters like hSERT and the process of returning the serotonin to the end of the neuron it comes from. This is thought to mean that serotonin stays in the space between the cells longer and increases the chances that the second cell will get the message.
