Genetic counselling. Alzheimer's disease: advances in genetics

Recent advances in DNA technology have allowed identification of those carrying the gene mutation for early onset Alzheimer's disease in some families, and provide the prospect of an effective treatment or cure in the future. While last week's article questioned the existence of late onset Alzheimer's as a distinct disease entity, this one illustrates how and why these scientific advances may have far-reaching psychosocial consequences for some family members. It suggests why there is likely to be an increase in demand for the kind of information and support which can be offered by a genetic counselling service.
