Knowing the research will help nurses aid families.
OVERVIEW: Three genes with autosomal dominant mutations have been identified that may lead to Alzheimer symptoms in carriers before they reach age 60. Genetic tests exist for Alzheimer disease, but they are considered useful only for the small number of families with a history of early-onset illness. As researchers continue to uncover evidence of genetic links to Alzheimer disease, nurses can expect to field questions from family members about genetic testing. The article presents a variety of questions nurses may be asked, as well as possible answers.
