An individual who experiences an intrusive obsession regarding germs, for example, may engage in hand washing to reduce the anxiety triggered by the obsession. Although it has been established that OCD has a neurobiological basis, research has been unable to point to any definitive cause or causes of OCD. Brain dysfunctions such as head trauma and encephalitis are also said to trigger obsessions and OCD among individuals. 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. Brain abnormalities particularly in the frontal lobes can cause obsessions. In sum, although the definitive cause or causes of OCD have not yet been identified, research continually produces new evidence that hopefully will lead to more answers. What causes OCD in the brain, anyone have any theories linked with cortisol, why does the brain lock in to this mode. This leads to alterations in neurochemicals such as dopamine and serotonin which further contributes to the obsessions and compulsions associated with OCD. Obsessive–compulsive disorder (OCD) is a mental disorder in which a person has certain thoughts repeatedly (called "obsessions") or feels the need to perform certain routines repeatedly (called "compulsions") to an extent which generates distress or impairs general functioning. Imaging studies have suggested that the brains of people with OCD function with characteristic differences. the receptors in the brain that Seretonin attaches to that causes the OCD problems. Genetics are thought to be very important. But these random thoughts get “stuck” in the brains of individuals with OCD; they’re like the brain’s junk mail. Unfortunately, the exact way that serotonin to cause OCD isn't known. According to the cognitive model of OCD, everyone experiences intrusive thoughts. So why does the brain of individuals with OCD work this way? ; Genetics.

Posted May 15, 2017 Stress can, however, be a factor in triggering OCD in someone who is predisposed to it, and OCD symptoms can worsen in times of severe stress. Imbalances in neurotransmitter systems such as neurochemical serotonin, as well as in the neurochemicals dopamine and glutamate, possibly appear in OCD. Studies suggest the infection doesn’t actually cause OCD, but triggers symptoms in children who are genetically predisposed to the disorder. We think there are two main ones. The person is unable to control either the thoughts or activities for more than a short period of time.

People with OCD, however, misinterpret these thoughts as being very important, personally significant, revealing about one’s character, or having catastrophic consequences. Everyone experiences intrusive, random and strange thoughts. Fropm this study, it is not possible to say that the brain abnormalities “caused” OCD. Brain scans have also shown that people with OCD often have abnormalities within the brain, particularly in the orbital cortex (the part of the brain above the eyes) and in deeper structures such … OCDmay have a genetic component, but specific genes have yet to be identified. 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. But since serotonin acts as a chemical messenger in the brain, there is likely some component of the mind that is being told to have more negative thoughts and engage in compulsive behaviors. Research shows that OCD does run in families, and that genes likely play a role in the development of the disorder. You could say your hardware and software. There are specific parts of the brain that give feedback in order to prevent a person from doing a task over again. OCD sufferers have differing levels of blood flow in certain brain regions. Because this washing ritual temporarily reduces the anxiety, the probability that the individual will engage in hand washing when a contamination fear occurs in the future is increased.

For severe cases of OCD, brain surgery techniques have emerged in the last decade as an option – and the new results are consistent with their effects. It is believed that OCD likely is the result of a combination of neurobiological, genetic, behavioral, cognitive, and environmental factors that trigger the disorder in a specific individual at a particular point in time. There appears to be a link between OCD and differences in the frontal cortex and subcortical structures of the brain. ... Serotonin is a brain chemical that transports messages to and from the nervous system. 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. There doesn't seem to be one cause for OCD but multiple causes: neurobiological and psychological. Brain structure and function. 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. In other words, what causes OCD? Environmental factors may also contribute to the onset of OCD. This research is often described in terms of chemical imbalances in the brain, faulty brain circuitry or genetic defects. Serotonin is a chemical in the brain known as a neurotransmitter.

In some, this could be a traumatic brain injury that leads to the development of compulsions. People with severe OCD symptoms may have a second variation in the same gene. No one really knows what other factors might be involved, perhaps an illness or even ordinary life stresses that may induce the activity of genes associated with the symptoms of OCD. “The simple answer is that we don’t know what causes OCD … We have a lot of clues … We think OCD is caused by some combination of genes, the environment and development …” The neurobiology of OCD is still being sorted out, but current perspectives suggest that at the root of OCD are problems with communication between three brain areas: the cortex, striatum, and thalamus (i.e. 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. 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).
