The impact of deafness on children, those of working age and elderly people is discussed highlighting the specific effect of genetic factors. In particular there are chapters on deafblindness and otosclerosis and NF2 (a potentially lethal condition). The Who definitions and ICF are used as a framework for considering the effect on people’s lives of impairment and their participation in society. This provides a bridge between the medical and social models of disability. Contributors write from both their professional and personal experience in order to try and address some of the issues raised by the real impact of genetic deafness on everyday life and how these can best be tackled by those working in the field.
