The cause [s] of
conditions like dyslexia and other learning disabilities [often all lumped together, but can be very different] is still unknown, although there are a lot of theories, and my own personal view is that ultimately a number of «triggers» will be found.
If your teen suffers from
conditions like ADHD,
dyslexia, or other
conditions that affect their academic success, it's natural to feel stressed and overwhelmed, which often shows up in a teen as behavior issues, obstinacy, apathy, or strong emotional reactions to seemingly small stresses.
