Final answer:
The statement that atopic dermatitis tends to run in families is true, indicating a genetic component to the condition that often presents as part of the atopic triad, which includes asthma and allergic rhinitis.
Step-by-step explanation:
True or False: Atopic dermatitis has a tendency to run in families. This statement is true. Atopic dermatitis, also known as eczema, is a condition that is often seen to run in families, suggesting a genetic component to its development. This condition is characterized by dry, itchy skin that can become red and inflamed when scratched. Atopic dermatitis is part of what's known as the atopic triad, which also includes asthma and allergic rhinitis (hay fever), all conditions that are known to be affected by genetics and family history.
The prevalence of atopic dermatitis in families highlights the role that genetics play in the likelihood of developing certain immune-related conditions, such as allergies and autoimmune diseases. While having a family member with atopic dermatitis increases an individual's risk for developing the condition, it does not guarantee that it will occur, since environmental factors also play a role in its onset and severity.
