Among these parts are the orbitofrontal cortex, the anterior cingulate cortex (both in the front of the brain), and the striatum, and the thalamus (deeper parts of the brain). 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 brain-based disorder resulting in disempowering thought and behavioral patterns. Neurological Causes. 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).

Overestimation of threat: a belief that negative events are very probable and that they will be particularly bad; 5. There appears to be a link between OCD and differences in the frontal cortex and subcortical structures of the brain. So why does the brain of individuals with OCD work this way? For example, traumatic brain injuries have been associated with the onset of OCD, which provides further evidence of a connection between brain function impairment and OCD. 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. These brain structures use a neurotransmitter (basically, a chemical messenger) called serotonin. An overactive molecular signal pathway in the brain region of the amygdala can lead to obsessive-compulsive disorder.

Most people have a spam filter and can simply ignore incoming junk mail. 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. You have inflammation in the brain. Physical Causes of OCD.

Brain dysfunctions such as head trauma and encephalitis are also said to trigger obsessions and OCD among individuals.
