Baxter’s study showed that patients with OCD had elevated brain activity in areas of the frontal lobes (particularly the orbital cortex) and the basal ganglia. Research suggests that OCD involves problems in communication between the front part of the brain and deeper structures of the brain. For example, a recent review of twin studies [1] has shown that genes play a larger role when OCD starts in childhood (45-65%) compared to when it starts in adulthood (27-47%). Learning theorists, for example, suggest that behavioral conditioning may contribute to the development and maintenance of obsessions and compulsions. Obsessive-Compulsive Disorder (OCD) is a chronic mental disorder that manifests as obsessive thoughts that cause distress in the sufferer, along with compulsions to perform certain behaviors in an effort to lessen the anxiety caused by the obsessive thoughts. The exact cause of OCD is unknown, but researchers believe that certain areas of the brain may not respond normally to serotonin, a chemical that … These brain structures use a neurotransmitter (basically, a chemical messenger) called serotonin. We explore the causes… SSRIs (Selective serotonin reuptake inhibitors), which are class of drugs that affect serotonin, are known to reduce major depressive disorder in a good number of people with OCD. ... Serotonin is a brain chemical that transports messages to and from the nervous system. Most people experience symptoms early on and are usually diagnosed before the age of 19. While, we still do not know the exact cause or causes of OCD, research suggests that differences in the brain and genes of those affected may play a role. Foundation.

Some brain imaging research has noted differences in parts of the brain structure, including the frontal cortex and subcortical structures, between people who have OCD and those who don’t. Research findings suggest that OCD symptoms may involve communication errors among different parts of the brain, including the orbitofrontal cortex, the anterior cingulate cortex (both in the front of the brain), the striatum, and the thalamus (deeper parts of the brain). Imbalances in neurotransmitter systems such as neurochemical serotonin, as well as in the neurochemicals dopamine and glutamate, possibly appear in OCD. Pictures of the brain at work also show that, in some people, the brain circuits involved in OCD become more normal with either medications that affect serotonin levels (serotonin reuptake inhibitors, or SRIs) or cognitive behavior therapy (CBT). PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections) is a type of OCD that occurs in childhood following the body’s reaction to infection. A sensitive brain and compulsive anxious behaviors. Brain lock refers to four areas of the brain that are overstimulated in OCD patients; in essence, these four structures are "locked" together as one in patients with OCD. Research is the key to finding the cause of OCD. OCD is known to be an inheritable disease, but because of the difficulty of identifying genes that may cause it, another approach is to look for “endophenotypes” – measurable physical characteristics (such as differences in brain structure in this case) which suggest how the disease might be inherited. Obsessive-compulsive disorder (OCD) is a mental illness that causes repeated unwanted thoughts or sensations (obsessions) or the urge to do something over and over again (compulsions). Some people start having symptoms early, often around puberty , but it usually starts during early adulthood.

As a result, compulsive behavior not only persists but actually becomes excessive. Brain abnormalities particularly in the frontal lobes can cause obsessions. Brain dysfunctions such as head trauma and encephalitis are also said to trigger obsessions and OCD among individuals. Experts aren’t sure of the exact cause of OCD. Imbalances in the peptide serotonin (chemical nerve cells), as well as in the peptide dopamine and glutamate, probably exist in OCD. This is why medication for most anxiety disorders, including OCD, involves antidepressants known as selective serotonin reuptake inhibitors or SSRIs. Dr. Steven Phillipson explains what causes fears and intrusive thoughts in the brain's of Pure O sufferers. Some experts think that OCD that begins in childhood may be different from the OCD that begins in adults. the receptors in the brain that Seretonin attaches to that causes the OCD problems. Obsessive-compulsive disorder (OCD) is an anxiety disorder that—like other mental health conditions—has a range of causes. The final key part of the brain that’s related to OCD is the caudate nucleus. More specifically, these areas of the brain may not respond normally to serotonin, a chemical that some nerve cells use to communicate with each other. Serotonin is a prime candidate for a potential cause or contributing factor to OCD. An overactive molecular signal pathway in the brain region of the amygdala can lead to obsessive-compulsive disorder. Abnormalities in neurotransmitter systems – chemicals such serotonin, dopamine, glutamate (and possibly others) that send messages between brain cells – are also involved in the disorder. Here are some reasons that explain the causes of OCD, according to science: Here Are 6 Causes of OCD And How to Fix It 1. But these random thoughts get “stuck” in the brains of individuals with OCD; they’re like the brain’s junk mail. However, it's unclear this is the cause or is an effect of the condition.
