Attention Deficit Hyperactivity Disorder

ADHD (Attention Deficit Hyperactivity Disorder)

What is Attention Deficit Hyperactivity Disorder?

Attention Deficit Hyperactivity Disorder (ADHD) is a treatable neurobiological condition, resulting in difficulties with impulsiveness, attention span and often, but not always, hyperactivity. It is estimated to affect between 3 and 5% of children.

While many children have lots of energy and can find it hard to concentrate, a child with ADHD will display this behaviour constantly and the problem is much more extreme. As a result they may find it difficult to fit in at school. The problem may continue into adulthood if a child with ADHD does not get the help they need.

Is ADHD a learning disability?

No. ADHD is not a learning disability. However, children with the condition may be more likely to have specific learning disabilities as well such as dyslexia.

What are the symptoms of ADHD?

The following behaviours are characteristic of ADHD and usually occur before the age of seven:

Onset of ADHD may be from as young as 18 months; however the condition is often not noticeable until around age 5, when the child starts primary school.

What causes ADHD?

While the cause of ADHD is not certain, research has shown that certain areas of the brain work more slowly in children with ADHD. Genetic factors are thought to be involved as ADHD tends to run in families. Head trauma or complications at birth resulting in injury to the brain have also been implicated in the development of ADHD; however these are only thought to be factors in a few cases. Cigarette smoke and alcohol abuse during pregnancy may also be linked to development of ADHD in the child. Food allergies, excess sugar, poor home life and watching too much TV are not thought to be factors in the development of ADHD.

How is ADHD diagnosed?

A diagnosis of ADHD may be considered if your child exhibits a number of the symptoms listed above before the age of seven and for more than six months. Children do not have to be hyperactive to have ADHD many children with ADHD are not hyperactive but still find it difficult to focus. If the child displays significant problems with concentrating or paying attention, but is not hyperactive, it may be referred to as Attention Deficit Disorder (ADD) rather than ADHD.

Early diagnosis and treatment has a major psychological, social and educational impact - it can help to spare your child the distress of inappropriate social skills and deflated confidence.

If your first port of call is a GP, your child may be referred on to a child psychiatrist who can then diagnose the condition. However often, a primary school teacher will be the first to raise concerns with parents. With the parents' consent, the National Educational Psychological Service (NEPS) will be contacted. As part of this service, a psychologist will be sent to the school to assess the child and determine what they need.

There are waiting lists for this service however and it is not available to secondary schools.

How is ADHD treated?

There is no single, simple treatment. Instead, treatment comprises a combination of medication (mainly psychostimulants and antidepressants), parent training, child and parent counselling and a special education environment. Some alternative and controversial treatments have been suggested - for example, dietary intervention, vitamin supplementation and optometric vision training - but there is no scientific evidence to support these theories.

Some parents worry that medication may sedate their children or make them feel 'dopey'. However when used correctly, this should not happen. In fact, it will often make children more focused and alert. Medication may not help in a small number of cases.

If your child does experience negative side effects, this may be because the medication itself does not suit them, the dosage is wrong or the interval between doses is wrong.

Drug-free interventions that have been shown to be effective include educational interventions, behaviour modification, parent training and anger management.

What is the long-term outlook for children with ADHD?

A lot can be done for people affected by ADHD, however this can depend on how early they are diagnosed. If a young person slips through the net and fails to be diagnosed, they are at risk of leaving school early and suffering problems such as low self-esteem and depression.

Adults with ADHD may have good attention spans but remain restless/fidgety and have to keep busy. Significant progress has been made in treatment, although much remains uncertain or ill-defined.

Can any professional tell me is it more benefical for a child with ADHD to live in a rural environment where he would have more space and would be less stimulated and less likely to get into trouble?

Hi, I'm worried that I may have ADD. I'm 27, reasonably healthy and I have good friends and family. But I find it extremely difficult to start tasks. Once i do i become restless and try to rush them and mostly only half finish them. My work is suffering as I constantly daydream and get distracted by my personal interests only to get distracted from my interests by something trivial. Plus I have difficulty following simple directions and arranging my timetable so in the end I have dozens of things planned but only usually get maybe one completed. If at all. I worry a lot and despite having a cool and calm demeanour I have great anxiety about talking to people and meeting people. I get quite paranoid that people don't like me and that they will be aggressive towards me. I worry about this as sometimes I can have a temper. I am quite creative and I write and play music but i find that I have so much going on that I can't get one song or story written as I'm thinking about the next or the previous. I hope someone has some suggestions or literature that I can get that may explain my problems. Thank you

Hi Id sounds like you might well have ADD - anxiety, irritability and temper can be part of it. Mostly I think from the frustration of things not working out as well as genetic susceptibility to irritability and anxiety. Constant thinking/worry etc. These may all be the negatives of ADD but usually once diagnosed - it all changes for the better, you get treated, have more personal control and confidence. Either way - whether its ADD or just anxiety disorder - you are suffering so I suggest you get some support and assessment anyway. Prof Michael Fitzgerald for ADHD assessment or Dr. Sean Fennell - North Dublin Una Fitzsimons psychologist/psychothertherpist for ADHD also south dublin. All are good and very up to speed with late diagnosis ADHD. Look up website for numbers - Cathy will direct you to the people above. Good luck. You deserve a break.

To my knowledge, ADHD can be triggered by food allergies. For me once I stopped the foods detected I found that I had a much clearer head!
