Diagnosing ADHD can be difficult, especially as your child gets older. But for many, it can be the explanation for difficulties at school. It’s never too late to get an ADHD diagnosis. In fact, you’ll be surprised at the resources available to your child once the problem is identified.
ADHD symptoms: Understanding what ADHD looks like

What do these students have in common?
Jan never did any homework while attending her large public high school, but she was bright and had an excellent memory. Her teachers and parents often said things to her like, “You’re so smart. If only you would work harder, you could be the top student in your class.” Nonetheless, she was able to get good enough grades to be accepted into a highly ranked large state university.
Norah was an artistic and forgetful girl whose room was always a disaster. She did her homework with other classmates or her older sister, who helped her stay on task. She got excellent grades at her small all-girls religious school.
Ned always turned his homework in late, but the teachers at his small private school made allowances because he participated in class. He had a high grade point average and outstanding test scores.
All of these students had attention deficit hyperactivity disorder, and had had it since childhood, although it was never officially diagnosed. They had mostly inattentive symptoms rather than the more familiar pattern of hyperactivity and impulsivity.
What is ADHD? Diving into a diagnosis

Students with the hyperactive type of ADHD are the ones you commonly think about when you hear about ADHD. They fidget and squirm in their seats, talk nonstop, and are constantly in motion. They are impulsive and act without regard for consequences. Thus, these students will cause enough disruption at home or school to get their condition diagnosed early on.
Kids with inattentive ADHD may not be noticed by teachers. They have difficulty focusing but also have innate deficits in what's called "executive functioning," which involves skills such as organizing, planning complex actions, and being able to look forward and anticipate consequences. They might be easily distracted, miss details, and forget things. They also have difficulty processing information as quickly and accurately as others. “The most comprehensive way that ADHD is diagnosed is through a neuropsychological assessment,” Katherine Chan, a licensed marriage and family therapist, told Mom.com.
When children with inattentive symptoms face situations that are difficult and can't figure out a way to manage it, they tend to shut down and just avoid the situation. They may feel too ashamed to ask for help. Since they don't themselves realize that they have an actual deficit, they can¹t explain what's going on.
People are often surprised to hear that ADHD can be undetected until even the college years, but it happens much more often than you'd think. Elementary, middle, and high schools provide significant structure and support, so students with milder types of ADHD can succeed academically despite their deficits. In contrast, the college environment provides them with very little structure and accountability.
In elementary, middle, and high school, classes are held every day. They are small enough so that teachers know each student. The deadlines for homework assignments are short, and students get constant feedback about how they are performing. Parents are notified if the student begins to slip, and remedial action can be taken.
It¹s much easier for students to fall between the cracks when they get to college. Freshmen frequently take large lecture courses, where attendance is not taken. They spend much less time attending classes compared to high school, so they need to be able to structure their time in between classes more independently and effectively.
In certain classes, grades may hinge on just a few exams. In other classes, students may be given weeks to read large volumes of material and write long papers that will determine most of their grade. Therefore, students with ADHD can and often do procrastinate to a much greater degree than they could get away with in earlier grades.
Parents of college students are rarely notified when their children are struggling academically. Privacy laws prevent colleges from sending grades home to parents without the student's permission, even though the parents are footing the tuition bills. Thus, the first information the parent may have about a child¹s school problems often comes when the child arrives home at the end of the first or second semester with news that he's on academic probation.
How to get diagnosed for ADHD: Get information

If you recognize your child in the above vignettes, the first step is to learn more about ADHD. You can start by checking out the CHADD (Children and Adults with Attention Deficit Hyperactivity) website. A good book to look at is Driven to Distraction by Edward M. Hallowell.
Then consider having your child evaluated by a psychiatrist or behavioral pediatrician who specializes in the disorder. If they receive the diagnosis, you can discuss the type of supports he needs, including medications, counseling, and perhaps extra support from his school.
When I see such students, I start by helping them understand the way their brain functions. Once they arrive at my office, they and their parents can be quite demoralized, frustrated, and angry with one another. Understanding that their child is not “lazy, crazy, or stupid” can go a long way toward easing tensions and building self-esteem.
The next step is to help the student learn how to manage their disorder in a school setting. They may need to take medications prescribed by their doctor. They may do better with smaller classes and assistance like tutoring. Many schools these days have learning centers where they can get help.
But no matter how much you try to avoid problems, inattentive ADHD often doesn’t show up until after a semester of failure. This can’t always be prevented, despite your best efforts.
If it happens, don’t panic. As I tell my patients, you are gathering data about yourself, so everything you go through gives you a better idea about what supports you need in order to function as best you can. “Certainly, as a mom, getting a diagnosis for your child can be life changing and overwhelming,” Dana Baker, a mother of an ADHD child, told Mom.com. Take the time to understand the diagnosis and the options available to you and your child.
