Despite affecting 3-7% of UK schoolchildren (of whom up to half will continue to have symptoms in adulthood) ADHD remains a poorly understood condition by the general public. For more than 20 years ADDISS has been working to improve awareness and understanding of ADHD by providing information, training, and support to sufferers of ADHD, their parents and carers, and healthcare professionals.

We support a multi-disciplinary assessment and treatment protocol, including education and behavioural interventions, with or without medication. We always keep an open mind and try to help families find their own most appropriate approach to intervention.

ADHD may have serious consequences, which can include under-performance at school, depression, problems with relationships, problems finding and keeping a job, and criminal behaviour.

ADHD exists in conjunction with many other conditions whose symptoms can overlap and mask those of ADHD such as Asperger’s syndrome, language disorder, dyspraxia, and obsessive compulsive disorder.
