Thus, OCD is a biological disorder, rather than a “mental problem.” Interestingly, researchers bolstered the notion that the basal ganglia causes OCD when they linked the onset of OCD symptoms to several events, including: bacterial infections, hypoxia (lack of oxygen to the brain) and neurotoxic agents.

How does the biological perspective explain compulsions?
Biological perspective of obsessive-compulsive disorder focuses on the idea that obsessive-compulsive disorder may be linked to biological factors (LAMBERT, KINSLEY, 2005). Twins studies suggests that if one identical twin displays obsessive-compulsive disorder, the other can also develops the same disorder.
What are the biological and behavioral problems that are associated with obsessive compulsive disorder?
Problems resulting from obsessive-compulsive disorder may include, among others: Excessive time spent engaging in ritualistic behaviors. Health issues, such as contact dermatitis from frequent hand-washing. Difficulty attending work, school or social activities.
Is OCD caused by a chemical imbalance?
Is OCD Caused by a Chemical Imbalance? While studies in the past have shown possible links between chemical imbalances and deficiencies, including serotonin production issues, recent research has largely disproven any connection between an OCD diagnosis and chemical imbalances in the brain.
What part of the brain causes OCD?
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).
What causes compulsive behavior?
Compulsions are learned behaviours, which become repetitive and habitual when they are associated with relief from anxiety. OCD is due to genetic and hereditary factors. Chemical, structural and functional abnormalities in the brain are the cause.
How does biological psychology explain behavior?
The biological approach believes behavior to be as a consequence of our genetics and physiology. It is the only approach in psychology that examines thoughts, feelings, and behaviors from a biological and thus physical point of view. Therefore, all that is psychological is first physiological.
What triggers OCD in a child?
Causes of OCD We do know that it’s common for children to develop OCD if family members have a history of anxiety or if children have been through a stressful or traumatic event. And in some rare instances, children develop OCD symptoms after a streptococcal infection (a bacteria that can cause throat infections).
What chemicals are linked to OCD?
Is OCD Caused by a Chemical Imbalance? Changes in the neurochemical serotonin, as well as in the neurochemicals dopamine and glutamate, are likely present in OCD. Indeed, medications like the antidepressants known as selective serotonin reuptake inhibitors (SSRIs) improve symptoms for many people.
What chemical in the brain causes obsession?
These medications counter the brain’s imbalance of serotonin, the chemical linked with obsessive-compulsive disorder. It is important to monitor your response to medication, which usually becomes fully effective within several weeks.
Is OCD caused by lack of serotonin?
Researchers have found that obsessive-compulsive disorder (OCD), an anxiety condition, is linked to low levels of serotonin. Serotonin, a hormone/neurotransmitter, performs a variety of functions in the body, which is why a serotonin deficiency can lead to anxiety-provoking OCD symptoms.
Can OCD be caused by trauma?
Not a few patients with obsessive-compulsive disorder (OCD) have experienced events that affected the onset. The onset of OCD is not limited to the original meaning of trauma; rather, traumatic experiences such as unexpected exposure to contaminants or various stressful life events often cause the onset of OCD.
Can you see OCD on a brain scan?
OCD was one of the first psychiatric disorders in brain scans showed evidence of abnormal brain activity in specific regions.
Can OCD be caused by head trauma?
OCD and Traumatic Brain Injury. In addition to changes in cognitive function, behavior, and mobility, TBI can trigger symptoms of OCD including obsessions and compulsions. OCD following a TBI usually occurs soon, if not immediately, after the event has taken place.
Can stress cause OCD?
An OCD episode can be triggered by anything that causes, stress, anxiety, and especially a feeling of lack of control. For example, if a person with OCD develops cancer, which can certainly trigger obsessions and compulsions, especially with cleanliness.
What are the four biological explanations of behavior?
Surname 1 Name Instructor Course Date The four biological explanations of behavior include physiological, evolutionary, ontogenetic and functional. In terms of physiological, behavior is described as an activity of the brain.
What are the biological factors that influence human behaviour?
Abstract. A growing body of evidence suggests that biological factors such as genes, hormone levels, brain structure, and brain functioning influence the development and trajectory of conduct problems in youth.
What are biological influences?
Biological factors include genetic influences, brain chemistry, hormone levels, nutrition, and gender.
Do controlling parents cause OCD?
These results are consistent with those of our present study in the OCD patients. We conclude that paternal controlling and interfering rearing attitudes are linked to the development of OCD, and depression with obsessive traits, and not linked to the development of depression itself.
Is OCD inherited or learned?
The inheritance pattern of OCD is unclear. Overall, the risk of developing this condition is greater for first-degree relatives of affected individuals (such as siblings or children) as compared to the general public.
Can parenting cause OCD?
As previously indicated, there is no evidence that the way parents guide or discipline their children causes OCD. Parents should not be blamed when a child exhibits symptoms of this disorder.
What neurotransmitter is missing in OCD?
Recent evidence suggests that the ubiquitous excitatory neurotransmitter glutamate is dysregulated in OCD, and that this dysregulation may contribute to the pathophysiology of the disorder.
Does OCD cause memory loss?
It has been reported that episodic memory seems to be impaired in patients with obsessive-compulsive disorder (OCD) because the patients repeat a specific checking behavior, but it is still unknown if OCD patients show memory impairments associated with their unique symptoms or not.
What are the 4 stages of OCD?
- Step 1: Relabel. The critical first step is to learn to recognize obsessive thoughts and compulsive urges.
- Step 2: Reattribute.
- Step 3: Refocus.
- Step 4: Revalue.
What is best medication for OCD?
Antidepressants approved by the U.S. Food and Drug Administration (FDA) to treat OCD include: Clomipramine (Anafranil) for adults and children 10 years and older. Fluoxetine (Prozac) for adults and children 7 years and older. Fluvoxamine for adults and children 8 years and older.
