Even the NIMH, which is the leading federal agency for mental health research, admitted that scientists don't fully understand what causes ADHD. They have identified numerous factors that contribute to a child's odds of having ADHD, including the following:
- Genes, meaning some aspects of ADHD may be attributed to inherited traits
- A mother who smoked cigarettes, or used alcohol or certain drugs during pregnancy
- A fetus' exposure to environmental toxins during pregnancy
- Exposure to environmental toxins, such as high levels of lead, at a young age
- Low birth weight
- Brain injuries
NIMH also noted that ADHD is more common in males than females, while females with ADHD are more likely to have problems primarily with inattention.
Conditions common in people who have ADHD include learning disabilities, anxiety disorder, conduct disorder, depression and substance abuse.
How to tell if your child has ADHD
Most children who potentially have ADHD end up going for an evaluation shortly after they enter grade school, because that's when their inability to focus, follow directions and control behavior becomes a real barrier to success in a structured setting, according to Parenting,com. But the age range for diagnosis can include kids as young as 4 and up to age 18.
Parenting listed symptoms from the American Psychiatric Association's Diagnostic and Statistical Manual IV, (DSM IV), the criteria a doctor would use to diagnose your child. It noted that for behaviors from the list to "be truly considered signs of ADHD, they must last for six months, be more severe than in other children the same age – i.e., they're causing significant problems at school, home and/or in social settings -- and some symptoms should have been present before your child turned 7."
To be diagnosed with ADHD/inattentive type, a child would have displayed at least six of these nine symptoms for at least six months:
- Does not pay close attention to details, makes careless mistakes
- Often has trouble keeping attention on tasks
- Often does not seem to listen when spoken to directly
- Often does not follow through on instructions and fails to finish work or chores (because of failure to understand, not defiance)
- Often has trouble organizing activities
- Often avoids or dislikes things that take a lot of mental effort for a long period of time.
- Often loses things needed for tasks and activities
- Is often easily distracted
- Is often forgetful in daily activities
To be diagnosed with ADHD/hyperactive-impulsive type, a child would have displayed at least six of these nine symptoms for at least six months::
- Often fidgets with hands and feet or squirms in seat
- Often gets up from seat
- Often excessively runs about or climbs when not appropriate
- Often has trouble playing or doing leisure activities quietly
- Is on the go as if driven by a motor
- Often talks excessively
- Often blurts out answers before questions have been finished
- Often has trouble waiting his turn
- Often interrupts or intrudes on others
Easing the ADHD situation
Regardless of the way a child or adult developed ADHD, anyone with the diagnosis will require guidance and understanding from parents, families and teachers to reach their full potential and to succeed, according to the NIMH. "For school-age children, frustration, blame, and anger may have built up within a family before a child is diagnosed," it noted. "Parents and children may need special help to overcome negative feelings. Mental health professionals can educate parents about ADHD and how it affects a family. They also will help the child and his or her parents develop new skills, attitudes and ways of relating to each other."
Most children are evaluated for ADHD shortly after they enter grade school because their inability to focus, follow directions and control behavior becomes a real barrier to success in that structured setting. However, in 2011 the American Academy of Pediatrics expanded the age range of diagnostic guidelines to include kids as young as 4 and up to age 18.
ADHD has three subtypes; predominately hyperactive-impulsive, predominately inattentive, and combined hyperactive-impulsive and inattentive. That means your child may have all of the symptoms in one category, or several from each.
The symptoms listed below come from the American Psychiatric Association's Diagnostic and Statistical Manual IV, (DSM IV) and are the criteria a doctor would use to diagnose your child. However, because living, breathing kids are more than a collection of lists in a diagnostic manual, we'll also provide some examples of how these behaviors can play out in real life.
For the behaviors listed below to be truly considered signs of ADHD, they must last for six months, be more severe than in other children the same age – i.e., they're causing significant problems at school, home and/or in social settings -- and some symptoms should have been present before your child turned 7.
