This raises an important question: Can dementia skip a generation?

The answer depends on the type of genetic condition and its inheritance pattern.

A blood-based genetic test can sometimes fail to detect mosaicism, particularly when the genetically altered cell population is absent or present at a very low percentage in the blood.
