With summer fading, anxiety is on the rise for some students anticipating the return of school. But it isn't just the first days of classes that can provoke angst -- anxiety in school is seasonal and age dependent, say pediatric psychiatrists. And, they add, these issues are often predictable and highly treatable. "If parents are aware of the fears that might affect their school-age children at different times of the year, and at certain ages, there is a lot they can do to help," says Dr. John T. Walkup, director of child and adolescent psychiatry at NewYork-Presbyterian Hospital/Weill Cornell Medical Center and vice chair of the Department of Psychiatry at Weill Cornell Medical College.
