My son who is 9 years old was diagnosed with mono yesterday. He s had trouble concentrating in school and has recently failed a couple tests over simple material the teacher said 90 % of the class got A s on. My son is normally an A or B student and doesn t do poorly on tests. Is this something I should worry about or is simply fatigue from the mono causing lack of concentration in school?
