Regarding asthmatic symptoms that occur to children at childhood peroid and then subsided as they grown , is this considered as asthma or ..?!

Yes: Asthma is difficult to diagnose in the first 2-3 years of life however if a child is found to be allergic , then the risk of asthma rises significantly. If a child continues to wheeze after age 3 unrelated to a viral infection then he likely has asthma. Many young adults seem to "lose" their asthma during puberty yet recurrence is common in the late 20's. Asthma is asthma but the course varies.

Yes, Asthma: Asthma is mostly your body's response to certain allergens showing up as airway narrowing, resulting in difficulty in breathing. One can get diagnosed with it at any age, usually earlier in life. Many children growing up will have diminished symptoms, especially if they have changed their living environment etc.

Maybe: About 60% of wheezing in infancy is triggered by infections. It is often managed as we would manage asthma, but so many of them stop wheezing by school age, it is hard to consider a lifelong label for some of them. If they have a strong family history, eczema, or were admitted to an ICU in childhood, it is likely lifetime asthma.
