Individuals with OCD may also have other mental health conditions such as depression, attention deficit disorder/hyperactivity disorder (ADD/ADHD), anxiety, Asperger syndrome, eating disorders and Tourette syndrome (TS).
Various types of psychiatric disorders co-occur with OCD, including neurodevelopmental disorders (NDDs), mood disorders, anxiety disorders, severe mental illnesses (SMIs), and personality disorders (2, 8, 9).
Although OCD is a severe mental illness to have, other mental illnesses also often occur with it, such as Body Dysmorphic Disorder, Panic Disorder, Generalized Anxiety Disorder (GAD), and depression. Unfortunately, a dual-diagnosis has the potential to make treatment a bit more severe and complicated sometimes.
There are also conditions similar to OCD, such as hoarding disorder, skin-picking disorder, and hair-pulling disorder.
Imaging, surgical, and lesion studies suggest that the prefrontal cortex (orbitofrontal and anterior cingulate cortexes), basal ganglia, and thalamus are involved in the pathogenesis of obsessive-compulsive disorder (OCD).
In patients with obsessive-compulsive personality disorder, preoccupation with order, perfectionism, and control of themselves and situations interferes with flexibility, effectiveness, and openness. Rigid and stubborn in their activities, these patients insist that everything be done in specific ways.
Experts aren't sure of the exact cause of OCD. Genetics, brain abnormalities, and the environment are thought to play a role. It often starts in the teens or early adulthood. But, it can also start in childhood.
Studies show that OCD patients have excess activity in frontal regions of the brain, including the orbitofrontal cortex (OFC) and anterior cingulate cortex (ACC), which could explain their intrusive thoughts and high levels of anxiety, respectively.
Once thought to be psychodynamic in origin, OCD is now generally recognized as having a neurobiological cause. Although the exact pathophysiology of OCD in its pure form remains unknown, there are numerous reports of obsessive-compulsive symptoms arising in the setting of known neurological disease.
While some symptoms of obsessive-compulsive disorder (OCD) can be clear, others can appear in a number of other mental health conditions, like anxiety disorders, depression, schizophrenia, and autism.
Anxiety disorders that may occur with OCD include Separation Anxiety Disorder, Generalized Anxiety Disorder, Panic Disorder (panic attacks), Social Anxiety Disorder and Specific Phobias, such as fear of snakes or heights.
OCD has peaks of onset at two different life phases: pre-adolescence and early adulthood. Around the ages of 10 to 12 years, the first peak of OCD cases occur. This time frequently coincides with increasing school and performance pressures, in addition to biologic changes of brain and body that accompany puberty.
Under the ADA it considers a disability to be “a physical or mental impairment” that limits someone's ability to functioning in daily activities. It includes OCD to be a disability. Those victims who have no choice but to live with OCD know how much its symptoms can interrupt day-to-day living.
OCD was one of the first psychiatric disorders in brain scans showed evidence of abnormal brain activity in specific regions.
Obsessive compulsive disorder, or OCD, is an anxiety disorder which, like many anxiety disorders, is marked by low levels of serotonin. Serotonin, a type of neurotransmitter, has a variety of functions that make a deficiency a serious and anxiety producing issue.
Is OCD Inherited? Research shows that OCD does run in families, and that genes likely play a role in the development of the disorder. Genes appear to be only partly responsible for causing the disorder, though.
Obsessive-compulsive disorder (OCD) is a serious psychiatric disorder that affects approximately 2% of the populations of children and adults. Family aggregation studies have demonstrated that OCD is familial, and results from twin studies demonstrate that the familiality is due in part to genetic factors.
Hoarding or collecting things. Having the need for order, symmetry or perfection. Worrying about a serious disease despite medical reassurances. Compulsively cleaning/washing, checking, repeating or counting things.
It can be difficult, demanding and exhausting to live with a person who has OCD. Family members and friends may become deeply involved in the person's rituals and may have to assume responsibility and care for many daily activities that the person with OCD is unable to undertake.
It has been established that cluster-C personality traits are common in patients with OCD.
Magnetic resonance imaging (MRI) scans conducted to compare the volumes of different brain regions in people with and without OCD have found smaller volumes of the orbitofrontal cortex and the anterior cingulate cortex in individuals with OCD.
Individuals with OCD often have certain chemical imbalances present in the brain. Changes in the neurochemicals serotonin, dopamine, and glutamate are normally present in OCD cases.
