Genetic Explanations For OCD

Question 1

What is the role of the COMT gene in relation to OCD?

Answer 1

COMT gene is linked to increased likelihood of OCD through its effect on dopamine levels.

High levels of dopamine lead to increased motivation which may increase the likelihood of compulsions.

Question 2

What does the term ‘genetic vulnerability’ refer to in the context of OCD?

Answer 2

Genetic vulnerability refers to the inherited factors that may increase the likelihood of developing OCD.

This concept is supported by family studies that investigate potential inheritance patterns.

Question 3

True or False: The relationship between genes and OCD is definitively causal.

Answer 3

False

Research suggests correlation rather than causation, which raises issues about the validity of findings.

Question 4

What neurotransmitter is associated with the SERT gene?

Answer 4

Serotonin

SERT is involved in serotonin reuptake channels and is crucial for emotion regulation.

Question 5

Fill in the blank: Gene therapy involves the replacement of a _______ gene with a healthy version to treat disorders.

Answer 5

defective

This approach is controversial and raises ethical concerns.

Question 6

What are the potential risks associated with socially sensitive research on genetic explanations for OCD?

Answer 6

Socially sensitive research can lead to eugenics and societal rejection or punishment of individuals with certain genetic traits.

This highlights the ethical considerations in genetic studies.

Question 7

What did Ozaki (2003) aim to investigate in their family studies related to OCD?

Answer 7

Ozaki aimed to investigate potential inheritance of OCD.

Their findings suggested evidence of genetic factors contributing to increased likelihood of OCD.

Question 8

What is a criticism of the genetic explanations for OCD?

Answer 8

Genetic explanations often ignore environmental factors that can also contribute to the development of OCD.

This suggests a need for a more holistic approach in understanding the disorder.

Question 9

How do COMT and SERT genes relate to other disorders?

Answer 9

COMT and SERT genes have been found to be more common in individuals with disorders like autism and anorexia.

This indicates potential overlapping genetic vulnerabilities across different mental health conditions.

Question 10

What is a limitation of the research regarding genetic causes of OCD?

Answer 10

The research lacks consistency and reliability, making it difficult to trust conclusions about inherited genetic causes of OCD.

This inconsistency calls for further investigation and validation of studies.
