The number of children being diagnosed with the behavioural disorder ADHD is currently 5 and 10 percent of the population in the UK. ADHD is characterised by symptoms of inattention, difficulties organising thoughts and ideas, problems inhibiting inappropriate speech and behaviour and impaired memory processes.
