Are there obvious signs of learning disabilities in teens with ADHD?

Because teens with attention deficit hyperactivity disorder (ADHD) seem healthy, it is harder to tell whether they have learning disabilities. Typically, schoolwork and social relationships are affected. Teens may have trouble with normal classroom activities. These could include reading, writing, calculating numbers, or speaking in public. With ADHD, teens find it difficult to learn and concentrate. They may be easily distracted and hyperactive. There are two categories of learning disabilities:

• Verbal: difficulties with spoken and written words
• Nonverbal: difficulties with processing what is seen (as with numbers)
