Overview and Facts of ADHD

Attention deficit hyperactivity disorder (ADHD) is a group of neurobehavioural disorders and is among the most typical one in childrend which usually lasts into adulthood. Symptoms include inattentiveness, overly active and impulsiveness. Common signs of ADHD comprise of:

  • a short attention span
  • restlessness or constant fidgeting
  • being easily distracted

ADHD may appear in people of any intellectual capability. Nevertheless, most individuals affected by ADHD also have learning challenges. They might also have additional complications such as sleep disorders. The signs of ADHD are usually first seen at a young age, and could be more apparent when a child’s circumstances change, such as starting school. Young children are normally active and simply distracted and preoccupied. Nevertheless, if these characteristics are too much for a child’s age and normal developmental level, and impacting their everyday life, they could show ADHD.


ADHD is a common behavioral condition in U.S and most of the world. It is believed the disorder impacts 2-5% of children in school and young adults. It could be a life time disorder, and most children affected, will have symptoms when they become teenager and adult. Approximately over two thirds of children identified as having ADHD will continue to have symptoms as teenagers. Then it is likely that two thirds of them will present symptoms as adults. It is unclear whether adult ADHD can happen without first occurring in childhood.

What are the types of ADHD?

There are 3 different types of ADHD, determined by types of signs and symptoms in the individuals

Predominantly Inattentive Presentation: It’s difficult for people to coordinate and accomplish a task, to concentrate on specifics, or to follow discussions, conversations or directions. People affected with this type of ADHD are easily sidetracked or don’t remember details of day-to-day routines.

Predominantly Hyperactive-Impulsive Presentation: The patient fidgets and talks a lot. It is tough to sit still for long time.  For example they can’t sit for dinner or do homework.  The person is restless and is impulsive. Somebody that is impulsive may disrupt other people a lot, take things from others, or talk at inappropriate times. It’s difficult for the individual to wait their turn or pay attention to directions. An impulsive individual might have more mishaps and injuries than others.

Combined Presentation: Signs of the above mentioned are equally seen in the person.

What Causes ADHD? 

No one knows  the exact cause of this disorder but studies have shown that it’s likely genetics. Research also indicates that there might be variations in how a brain functions in individuals with ADHD. Some other possibilities include:

  • Brain injury
  • Alcohol, tobacco and drug use during pregnancy
  • Premature birth
  • Low birth weight
  • Exposures to environmental toxics

There is no evidence that ADHD is a result of consuming too much sugar, poor parenting, social factors such as financial hardship or watching too much TV.   Obviously, in some people, these and many other things may make symptoms worse but there are no proof that they are the primary reasons for it.

What are some of the signs?

It is natural for kids to sometime misbehave and not pay attention but children with ADHD continue with these behaviors to teenage years and adulthood.  They will have problems at home, school and with their friends.

Here are some of the signs:

  • daydreaming a lot
  • forget or lose things a lot
  • squirm or fidget
  • talk a lot
  • make careless mistakes or take unnecessary risks
  •  find it difficult resisting temptation
  • have trouble taking turns
  •  problems with getting along with others

How ADHD is diagnosed?

Diagnosis usually occurs in children between ages 3 to 7 and in some cases, maybe at later age.  Adult ADHD is more difficult to detect since there is no conclusive list of age-appropriate signs.   There are many steps to diagnose a child with ADHD.  There isn’t a single test to do it as many other conditions such as depression, share similar symptoms.

Typically children go through medical exams to eliminate other conditions with similar symptoms as ADHD.  Then a checklist maybe provided to rate the symptoms and take history of the behavior from parents, teachers and other.

What are the treatments?

Generally, treatment includes a mix of medication and therapy.  ADHD is incurable but it can be managed with a good treatment plan, follow ups and monitoring the changes. Dealing with a child with ADHD is not easy and you need help.  Take your child to psychologist or developmental pediatrician and work with teachers and school staff to make sure your child will reach his/her potential.
