I always thought that allergies were caused by the increase in pollen in the air during the spring and fall. Yes, there are a wide array of causes of allergies. The causes of allergies may seem harmless, but daily exposure to these items can cause chronic medical problems in adults and children. Allergies are often difficult to detect because they are caused by common things a child is exposed to every day. It is an even greater challenge to parents of small children because the children often cannot express their discomfort.
Allergies can affect every system in a child's body including the central nervous system.
When a child is experiencing an allergic reaction to a particular type of food, parents will often note a sudden change in behavior or mood. These signs are just guidelines or starting points for parents. A child experiencing the symptoms noted above should undergo a complete allergy evaluation with a family physician or pediatric allergist. My child's grades are declining and his overall development at school has halted. I'm concerned that he may have a learning disability.
