From time immemorial adults have envied the energy, passion and spontaneity of children. For the same amount of time, adults have complained about those same qualities. It wasn’t until the late 1800’s that physicians attempted to define excessive activity and impulsivity as a clinical syndrome. And it wasn’t until 1980 that the term Attention Deficit Disorder (ADD) was officially adopted by the American Psychiatric Association. 
This article will examine the basics of ADHD including symptoms, some look alike conditions, possible treatments & side effects, and prognosis. Finally, it will discuss why the diagnosis remains controversial.

 There are three main symptoms of ADHD:
For a formal diagnosis these symptoms must:
Finally for children under 16 they must have at least 6 criteria for either inattention or hyperactivity/impulsivity. The criteria are listed below.
* For children and adults over the age of 16 at least five of the above criteria must be met, instead of six.
When a child is diagnosed with ADHD they are put into one of three categories:
Severity of symptoms is also specified:
Researchers have conducted numerous studies on those, who have ADHD, and found that the percentage of population with ADHD truly depends on the diagnostic criteria. In the United States, the criteria most commonly used are listed above. According to these criteria, the percentage of Americans with ADHD is approximately 7%. (3) However, when stricter criteria are used, the percent is approximately 5%. (3)
Therefore, the prevalence is approximately 6% for American adults. (3)
The only known cause for ADHD is genetic. That said, not everyone with family with a history of ADHD will have ADHD themselves and vice versa. Researchers believe that at least two genes are involved in the development of ADHD and it is likely other medical and environmental conditions affect the presence and expression of the disorder (e.g. specific symptoms and severity).
In addition to genetics there are many environmental factors which are correlated with ADHD, however it is unclear if they actually cause ADHD. Some of these are:
Research into the causes of ADHD is ongoing.
Summary: Causes and Risk Factors
If you are concerned about your child’s behavior the first place to start is with your child’s pediatrician. Most pediatricians are experienced with treatment and evaluation of ADHD. However if they feel your child’s condition is complicated, they may refer you to a child or family therapist or a psychiatrist for further evaluation and treatment.
A good history is the best way to diagnose ADHD. A physical exam and family history are essential to help rule out other causes of behavioral problems. Typically a psychiatrist will ask for medical records from the child’s pediatrician for review and will do only a focused neurological exam, as well as observing the child’s behavior closely during the appointment. Because they have evaluated hundreds of children with behavioral issues it is easier for them to notice behaviors which may be more typical of other problems than ADHD, and to assess any of those further.
There are some tests for attention and impulse control that are administered by computer. These are very accurate for detecting inattention and poor impulse control, but they are not able to identify the cause of inattention, which can be present for many reasons. That is why observing the child and getting a good history from parents, caregivers and teachers areis vital.
- Your pediatrician can diagnose simple ADHD.
- More complex problems will be referred to a specialist.
- Other conditions must be considered before a diagnosis is made.
- History and observation are vital for making a diagnosis.
The major treatments for ADHD include education, medication, assessment and treatment of any other conditions that interfere with attention, and educational accommodations as needed.
Education about the disorder for parents, the child and others involved in care of the child is the first part of treatment. Parents often must adjust expectations, family routines and disciplinary styles to suit the child’s strengths and weaknesses. A child with ADHD may have fewer symptoms with:
The calmer the parents are able to stay, generally speaking, the calmer the child will be. An ADHD child may often feel out of control, so greater structure and adult calmness can help reassure the child. When a child feels the world is in control it helps keep them be better able to pay attention and to cooperate with adults.
Other medications are sometimes effective for ADHD, but have not been approved by the FDA. Usually they are prescribed by a child psychiatrist or neurologist.
A summary detailing these medications can be found at this site, maintained by the American Academy of Child and Adolescent Psychiatry.
Sometimes basic education about managing ADHD is not enough. Play therapy for children and family therapy can be very helpful. In addition, support groups for parents and other caregivers can also be important tools for coping and learning.
Most children learn organizational, social and sequencing skills through normal family and school life, but some children benefit from extra exposure, which can often be through chores and games. Some of these can be focused on organizational skills, such as packing lunch or school supplies, playing memory games and repeating steps in order (dance routines, reciting songs or poems). Charts helping children identify emotions in themselves and others can be a good starting point for social skills.
In other cases a child may have a diagnosable learning disorder and may require more formal treatment. Often an occupational therapist can help with this, but a reading specialist or even an optometrist specializing in low vision or visual processing can help with this. These services are only sometimes provided through the schools and often can present a financial strain for families.
The frustration a child experiences from a learning disability can aggravate other emotional and behavioral issues the child has. Parents and siblings may also become frustrated. When these learning difficulties are addressed appropriately it may help the entire family.
Whether or not a learning disorder is present, a child with severe and poorly controlled ADHD (about 10% of children diagnosed and treated for ADHD) may require an individualized educational plan (or IEP). This type of plan can be very valuable as it allows the child to stay in a regular classroom with special limits on what is expected of the child and extra resources provided if necessary. At other times accommodations may be negotiated with the child’s teacher on a case -by -case basis. For example, a child who has great difficulty writing, might do his or her spelling word sentences by dictating them to a parent who writes them down for the child. This should generally be a temporary arrangement which prevents the child from falling behind in learning while the learning disability is being addressed.
Unfortunately, to date there is no reliable evidence for the usefulness of herbal remedies or biofeedback in the treatment of ADHD.
- Education about ADHD can help children and parents understand how to cope with symptoms and reduce tension at home.
- Medications are the mainstay of treatment for ADHD. There are several types available which are effective and generally safe when taken as prescribed.
- Therapy can be invaluable for families and children with severe ADHD or who have other coexisting disorders.
- Treatment of learning disorders and school accommodations may be needed.
- Many herbal and alternative treatments are available, but scientific and clinical data have not shown them to be effective as of March 2018.
Most children (and adults) have an excellent response to treatment for ADHD. Stimulants are effective in between 60 to 90% of cases. In the remaining cases there are often co-occuring conditions which complicate treatment, meaning that there are actually two or more conditions to be treated.
Up to one-third of children treated for ADHD may find that their symptoms diminish greatly in early adolescence and that they are able to discontinue medications altogether.
The remaining two thirds find they do much better on medication, at least while they are in a formal education setting.
And one third of children will become adults and find that they benefit from taking medication indefinitely. They will continue to struggle with impulsivity, interpretation of social cues and focusing unless the material is highly interesting to them. Fortunately, side effects of the medications are usually mild. Nonetheless it is vital for those who are on medication for ADHD long term to find and develop a good relationship with a psychiatrist for those who are on medications for ADHD for long term..
- Treatment is effective in 60-90% of patients.
- The other 10-40% have other conditions which also require treatment, or very severe symptoms.
- One third of patients seem to “grow out” of ADHD in early adolescence.
- One third may do better staying on medications while in a formal learning setting, but may not require medication long term.
- One third may do better remaining on medications indefinitely, depending on career and lifestyle choices.
1. Is ADHD a real disorder?
Yes, ADHD is a real disorder that affects all age groups, ethnicities, races, cultures, genders, economic groups, and sexual orientations.
2. Are all attention problems caused by ADHD?
No, in fact, ADHD is just one of many causes of inattention. Therefore, it is important to consider other factors that may be contributing to your child’s learning and discipline problems.
3. What are some nutritional deficiencies that can cause symptoms similar to ADHD?
The nutritional deficiencies that can cause symptoms similar to ADHD are:
In addition, essential fatty acid supplements and phosphatidylserine supplements may assist in brain and nervous system health ( Vayarin by prescription and various over the counter supplements).
4. Can exposure to toxins cause ADHD?
Yes, environmental toxins can impair attention and cause behavioral disturbances.
The most common and serious toxins are:

There are a variety of conditions that can mimic ADHD.
These conditions are listed below:
6. Can some mood and psychiatric disorders mimic ADHD?
Yes, some mood and psychiatric disorders can mimic ADHD, such as:
7. Are there any other neurological disorders that could be mistaken for ADHD?

Some of these disorders are listed below:
8. What about allergies – are there any allergies that could be linked to or mistaken for ADHD?
Yes, some allergies have been linked to or mistaken for ADHD.
These allergies are listed below:
9. Is ADHD Overdiagnosed?
The rate of diagnosis with ADHD has increased dramatically since 1980. However some states have a rate of 14% of children who are diagnosed with ADHD, other states have closer to 4% diagnosed with ADHD.[4,5,6] It is clear that in some places ADHD is underdiagnosed and in some places it is overdiagnosed.
This could be because:

The main symptoms of ADHD are: inattention, hyperactivity, and impulsivity. This condition can occur at any age, but it is usually diagnosed during childhood. In most cases, ADHD persists through adolescence and into adulthood. It typically affects approximately 9% of the general population and has been observed worldwide. ADHD can affect an individual’s self-esteem, romantic relationships, friendships, and academic and career success.
In fact, approximately 80% of those diagnosed with and treated for ADHD experience a reduction in symptoms (i.e. improved academic performance and better family and social relationships, along with decreased impulsivity and dangerous behaviors). However, approximately 20% of those diagnosed with ADHD do not receive satisfactory results from treatment.
For these individuals, additional problems – i.e. medical, developmental, and/or environmental in nature – should be addressed to help the child attain the best possible results. To be diagnosed with the condition, individuals must meet specific criteria. And, with early diagnosis and proper treatment, individuals with ADHD can go on to have happy and successful lives.
