Did you know it is thought that around 2% to 5% of school aged children may have Attention Deficit Hyperactivity Disorder (ADHD)? People are commonly diagnosed between age 6 to 12. There is no cure for ADHD but with the right support it can be managed; medication and therapy can help adults deal with the disorder.
The exact cause of ADHD is unknown, however a number of factors is thought to play a part, for instance brain function and structure, premature birth, exposure to certain toxins at a young age and passed on through genetics.
