Alzheimer’s gene test has limited value

A group of Australian researchers recently reviewed two decades of literature to determine what, if any, impact genotype testing is likely to have psychologically and behaviourally.

Compared with predictive/diagnostic testing for high-risk disease-causing gene mutations, Apolipoprotein E (ApoE) genotyping provides much less certain risk information, but applies to a much larger proportion of the population, the authors explained.

Of the few studies available on testing for early onset Alzheimer’s Disease, only a small proportion of patients suffered
