ADDISS provides information, training and support for parents, sufferers and professionals in the fields of ADHD and related learning and behavioural difficulties. All our activity is supported by a professional board of expert advisers. ADDISS supports a multi-disciplinary assessment and treatment protocol, including education and behavioural interventions, with or without medication, keeping an open mind to help families find their own most appropriate approach to intervention. ADDISS holds a 3-day national conference each year, bringing together professionals and people living with ADHD. ADDISS is a registered charity, run by volunteers and staff. Income from their bookstore and conferences directly funds their work, together with donations and grants.
