Which psychiatric disorder is noted to have a genetic transmission?

1. Enuresis

2. Conduct disorder

3. Major depressive disorder

4. Attention deficit hyperactivity disorder

The correct answer is: Enuresis

The correct response identifies a disorder that is well-documented in research as having genetic components in its development. Enuresis, also known as bedwetting, may exhibit a familial pattern, with some studies indicating that a family history of enuresis increases the likelihood of an individual experiencing the same condition. This suggests that there may be a hereditary factor involved, although environmental influences also play a significant role in this disorder. When looking at the other options, while conduct disorder, major depressive disorder, and attention deficit hyperactivity disorder also have genetic elements associated with them, the relevance and extent can vary. Conduct disorder can correlate with a family history of behavioral issues but doesn't always present a strong genetic framework as seen in some other disorders. Major depressive disorder certainly involves genetic factors; studies have shown that individuals with relatives who have depression are at a higher risk themselves. Attention deficit hyperactivity disorder (ADHD) is also recognized for its genetic components, with a higher prevalence in individuals who have affected family members. However, enuresis as a pediatric condition particularly highlights genetic influences in its manifestation, making it a notable example of a psychiatric disorder with documented genetic transmission.
