Explanation:

Options for this question:

  • <em>FAD is the result of a genetic change in one or more chromosomes.</em>
  • <em>Natural selection will continue to reduce the incidence of FAD.</em>
  • <em>FAD affects only the genes of middle-aged people.</em>

Alzhaimer's disease is a type of dementia that is characterized by neuronal degeneration, causing disorientation, memory and manual skills loss , among others. The familiar variety (FAD) is hereditary and is associated as a cause of disease and early Alzhaimer, before 60-65 years.

So far, three types of mutated genes related to FAD have been established:

  • PSEN₁ or presenilin-1 gene , more frecuent.
  • APP or amyloid precursor protein gene.
  • PSEN₂ or gene for presenilin-2, very rare or uncommon.

In some cases, people affected by FAD have alteration in more than one gene at the same time.
