I want to know the answer to the following question:
When asthma is caused by allergens that is called what?
All the background I'm provided with is that "Asthma may also be classified as atopic (extrinsic) or non-atopic (intrinsic), based on whether symptoms are precipitated by allergens (atopic) or not (non-atopic).". Is that enough to answer the question?
Answer: yes
