There are all kinds of conditions which are misdiagnosed this is not exclusive to ADHD. ADHD is a neurological disorder with the core symptoms of restlessness, distractibility and impulsivity, and short term memory problems these symptoms must be present to such a degree that they cause major problems in the life of the child or the adult being diagnosed. ADHD is not diagnosed based on behavior problems there is a list of criteria that must be met. It would be hard for someone not directly affected by the impact of this disorder to understand the devastating effects that it can have on a persons life. The medications used to treat ADHD do not "cure" behavior problems. One of the things the medications help with is activate a part of the brain (the frontal lobe) which is underactive in patients with ADHD. Once this part of the brain is activated the person is able to concentrate and helps improve short term memory which is often a big problem for people with ADHD. Often children with ADHD do not respond to behavior modification programs because they forget the instruction that was just given to them and they have no impulse control because nerve impulses in the frontal lobe are not firing off the way they should . The medication helps them by activating the frontal lobe. Parents who have kids with ADHD who happen to also have behavior issues have to work just as hard if not harder than any parent who has a child without ADHD and behavior issues even if the ADHD kid is on medication. People who do not have ADHD and develope traumatic brain injury to the frontal lobe can exhibit same symptoms as people with ADHD, because ADHD is a neurological disorder.
Furthermore, ADHD is highly hereditary. One theory that it is so prevalent in the USA is: People with ADHD tend to be highly creative, intelligent, risk takers. When the explorers left Europe to find a new land, what type of people would venture off to the unknown? Risk takers most likely people with ADHD, our ancestors.
To clarify another myth regarding medication: My husband has ADHD, my son age 11 has ADHD and My daughter age 8 has ADHD. They are not misdiagnosed. My son has inattentive type adhd he has trouble with short term memory, he is very distracted and disorganized this has a great affect on his life not only in school but at home and in social situations. My son does not have any behavior problems and yes he takes medication and once he started his life changed in ways that you will never imagine. At age 11 he came to me and said thank you mommy for not giving up on me.
On the other hand, my daughter also ADHD has the hyperactive/impulsive type with a lot of behavior problems, she does not take medication. We tried it and it is not the right treatment for her. We manage her ADHD with other types of modifications. There are many treatments for ADHD and what is right for one child may not be right for another.
Please don't ever judge a mother for doing what she feels is right for her child. Getting an ADHD diagnosis is not a relief. It is a life time sentence of everything being more difficult for that child. Parenting a child with ADHD is twice as hard as parenting a child without ADHD whether they are on medication or not.
One other thing, if someone does not have ADHD the medication won't help. Rarely do people with ADHD become addicted to their medication. People on pain medications have a far better chance of addiction.
Sorry to get on my soap box, I am just very passionate about this subject as I have come across many people who do not have the background knowledge regarding ADHD judge parents and their decisions regarding their children and their ADHD diagnosis. And yes, at times it is misdiagnosed as is everything else. I was misdiagnosed as having rheumatoid arthritis when it was actually a back problem.
