Question

Which is not true?

• A. VWD type 1 is mostly severe in children
• B. VWD type 3 is mostly severe in children
• C. VWD type 2 is more related to activity rather than levels
• D. VWD type 3 has severely low VWD

Hint:

VWD type 1 is usually a mild form with partial reduction in VWF levels, while type 3 presents with very low levels and more severe bleeding tendencies.

Answer 1

The Correct Option is A

To determine the statement that is not true regarding the different types of von Willebrand Disease (VWD), we need to evaluate each option:

• VWD type 1 is mostly severe in children: This statement is incorrect. VWD type 1 is the mildest form of VWD and usually results in mild to moderate bleeding symptoms. It is often not severe, especially in children.
• VWD type 3 is mostly severe in children: This statement is correct. VWD type 3 is the most severe form of the disease, characterized by very low or absent von Willebrand factor, leading to severe bleeding problems.
• VWD type 2 is more related to activity rather than levels: This statement is correct. VWD type 2 involves qualitative defects of von Willebrand factor, impacting its function more than its quantity. It is more about how the factor works (activity) rather than how much of it is present (levels).
• VWD type 3 has severely low VWD: This statement is correct. As stated earlier, VWD type 3 is marked by significantly reduced levels of von Willebrand factor, contributing to severe symptoms.

Therefore, the statement "VWD type 1 is mostly severe in children" is not true.
