ADHD in children is common

ADHD (attention deficit hyperactivity disorder) and ADD (attention deficit disorder) are conditions affecting thousands of families in the UK.

ADHD and ADD are psychiatric disorders characterised by impulsive, hyperactive or inattentive behaviour. The child may appear ‘naughty’, can struggle in school and home settings and be challenging to parent.

The good news is that ADHD and ADD are treatable; getting a diagnosis is the first step.

If you are concerned that your child or teenager may have ADHD or if their school have raised this as an issue, we can provide you with a full professional ADHD assessment for your child.

We understand that this can be difficult for both you and your child, but by seeking a proper diagnosis you will be able to determine the root cause of the issue and also determine the best treatment plan.

Assessments are often available within a few days. Call 020 3761 7026 to arrange your appointment today.

What causes ADHD in children?

ADHD in children is thought to result from many genetic and environmental factors interacting.


Children with a family history of ADHD are much more likely to have the condition themselves.

Many children with ADHD have been found to have slightly different gene structures. One study found a greater number of ‘copy number variants’( a term used to refer to deletions and duplications of certain chromosomes)2 in children with ADHD. Read about adult ADHD here.


Brain imaging has shown a difference in the brain size of children with ADHD.

Brain maturation is slower in children with ADHD; grey matter maturity is approximately 3 years behind that of children who do not have ADHD3.

The levels of neurotransmitters – the chemicals that deliver messages in the brain – are different in children with ADHD. Noradrenaline, linked to our ability to pay attention and dopamine, linked to our ability to control impulses, have been found in lower levels in children with ADHD. Medications, such as Ritalin, are used to adjust the levels of brain chemicals.


Premature birth and low birth weights are linked to an increased chance of ADHD

Factors such as alcohol, drug and cigarette use during pregnancy have links to a greater likelihood of ADHD.
