What is the biological explanation of OCD psychology?
Research has shown that imbalances in neurotransmitters, such as serotonin, dopamine, and glutamate, can contribute to OCD. These chemicals are responsible for transmitting messages in the brain, and when they are not functioning properly, they can lead to obsessive and compulsive behaviors.
What is the biological reasoning for OCD?
Etiology: Biological Models. Many investigators have contributed to the hypothesis that OCD involves dysfunction in a neuronal loop running from the orbital frontal cortex to the cingulate gyrus, striatum (cuadate nucleus and putamen), globus pallidus, thalamus and back to the frontal cortex.

What is the biological approach to explaining OCD 16 marker?
Explaining OCD The biological approach suggests that abnormal behaviour is caused by something physical happening in the body, which may be the result of genes. Genetic explanations: Genes may create a vulnerability (risk of developing) to OCD. There is evidence that OCD runs in families.
What is the biological explanation of OCD quizlet?
At least some cases of OCD may be explained by a reduction in the functioning of the serotonin system in the brain. Research has found sufferers of OCD have elevated levels of activity in the orbitofrontal cortex and the caudate nucleus (located in the basal ganglia).
Is OCD purely biological?
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.
What are the weaknesses of biological explanation of OCD?
Evidence to suggest OCD patients have abnormal levels of neurotransmitters or abnormal brain structure but this does not mean this is what causes OCD. Therefore other factors, such as learnt behaviour/ trauma may have a role to play in the cause of OCD, which will make the neural explanation only a partial explanation.
What is Freud explanation of OCD?
According to Sigmund Freud, obsessions are psychogenically related. Psychodynamic theory explains that OCD occurs because of a defensive regression to the early stages of development with the use of maladaptive defense mechanisms such as isolation of affect, undoing, displacement, and reaction formation.

Is OCD biological or environmental?
Is OCD More Genetic or Environmental? The development of OCD stems from a combination of genetic and environmental factors, though the balance of these influences is still somewhat undiscerned.
