What is AD/HD?
AD/HD is not a new diagnosis as some believe. It has been around for over a century, but it has been called different things like "minimal brain dysfunction", "hyperkinetic impulsive disorder," and "attention deficit disorder (ADD)." Currently the official recognized term since 1994 is Attention Deficit/Hyperactivity Disorder (AD/HD). However this term did not begin to be used more frequently until 2005. There are still many, including professionals, who use the terms ADD, ADHD and AD/HD interchangeably.
According to the DSM IV (the manual used by those diagnosing individuals with AD/HD) there are three different types of AD/HD:
- Predominantly Inattentive Type (some people refer to this as ADD)
- Predominantly Hyperactive/Impulsive Type (some refer to this as ADHD)
- Combined Type
It is estimated that the prevalence of AD/HD is:
- 5% - 7.5% in children
- 3-6% in adults
Once thought to be a childhood disorder predominately affecting males, we now know that approximately 75-85% of children will continue experiencing this condition on into adulthood and that it also affects females.
AD/HD has different causes and there are differing theories that have been studied, such as:
- Genetics
- Neurobiological challenges in several different areas of the brain, including the pre-frontal cortex
- Developmental disorder of self-control (Barkley 1995)
- Brain Insults – head trauma, toxins/chemicals
- AD/HD is NOT caused by sugar intake or poor parenting. Learn more about causes
